一、概述

随着技术栈的不断更新迭代，我们需要快速的在企业中搭建一个项目，并使用市面上前沿且稳定的技术栈。本期将跟大家一起从0到1搭建一个基于SpringBoot 的项目，并集成MyBatis-Plus、Druid、Logback 等主流技术。后续也会整合 Docker，自定义构建 Docker 项目，实现 Docker Compose 部署。源码附在文末。

二、创建统一的依赖管理

2.1、统一的依赖管理工程创建

创建一个名称为 my-project-dependencies的项目，该项目负责统一的依赖管理

pom.xml内容如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

   </build></project>

2.2、Maven托管

将其交给Maven托管

三、创建通用模块

3.1、创建通用模块工程

创建一个名称为 my-project-common的项目，该项目负责通用的类库以及工具类

pom.xml内容如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">    <modelVersion>4.0.0</modelVersion>    <parent>        <groupId>com.micromaple</groupId>        <artifactId>my-project-dependencies</artifactId>        <version>1.0.0-SNAPSHOT</version>        <relativePath>../my-project-dependencies/pom.xml</relativePath>    </parent>    <artifactId>my-project-common</artifactId>    <packaging>jar</packaging>    <name>my-project-common</name>    <dependencies>                <dependency>            <groupId>org.apache.commons</groupId>            <artifactId>commons-lang3</artifactId>        </dependency>        <dependency>            <groupId>cn.hutool</groupId>            <artifactId>hutool-all</artifactId>        </dependency>                        <dependency>            <groupId>com.fasterxml.jackson.core</groupId>            <artifactId>jackson-databind</artifactId>        </dependency>        <dependency>            <groupId>com.google.guava</groupId>            <artifactId>guava</artifactId>        </dependency>        <dependency>            <groupId>org.projectlombok</groupId>            <artifactId>lombok</artifactId>        </dependency>        <dependency>            <groupId>commons-collections</groupId>            <artifactId>commons-collections</artifactId>        </dependency>                        <dependency>            <groupId>org.apache.httpcomponents</groupId>            <artifactId>httpclient</artifactId>        </dependency>        <dependency>            <groupId>org.apache.httpcomponents</groupId>            <artifactId>fluent-hc</artifactId>        </dependency>        <dependency>            <groupId>org.apache.httpcomponents</groupId>            <artifactId>httpmime</artifactId>        </dependency>            </dependencies></project>

3.2、Maven托管

可以使用右侧的Maven 的 + 号来进行项目的托管。

3.3、完善目录结构

创建 src/main/java 目录后，创建包名，包名为：com.micromaple.my.project.common

此工程是放一些通用的类库或者是工具类之类的。

3.4、定义通用类库

3.4.1、返回状态码

创建常量包constant。

通用常量返回状态码HttpStatus

package com.micromaple.my.project.common.constant;/** * 返回状态码 * Title: HttpStatus * Description: * * @author Micromaple */public class HttpStatus {    /**     * 操作成功     */    public static final int SUCCESS = 200;    /**     * 对象创建成功     */    public static final int CREATED = 201;    /**     * 请求已经被接受     */    public static final int ACCEPTED = 202;    /**     * 操作已经执行成功，但是没有返回数据     */    public static final int NO_CONTENT = 204;    /**     * 资源已被移除     */    public static final int MOVED_PERM = 301;    /**     * 重定向     */    public static final int SEE_OTHER = 303;    /**     * 资源没有被修改     */    public static final int NOT_MODIFIED = 304;    /**     * 参数列表错误（缺少，格式不匹配）     */    public static final int BAD_REQUEST = 400;    /**     * 未授权     */    public static final int UNAUTHORIZED = 401;    /**     * 访问受限，授权过期     */    public static final int FORBIDDEN = 403;    /**     * 资源，服务未找到     */    public static final int NOT_FOUND = 404;    /**     * 不允许的http方法     */    public static final int BAD_METHOD = 405;    /**     * 资源冲突，或者资源被锁     */    public static final int CONFLICT = 409;    /**     * 不支持的数据，媒体类型     */    public static final int UNSUPPORTED_TYPE = 415;    /**     * 系统内部错误     */    public static final int ERROR = 500;    /**     * 接口未实现     */    public static final int NOT_IMPLEMENTED = 501;}

3.4.2、通用返回结果

创建数据传输包dto。

通用数据传输返回结果BaseResult

package com.micromaple.my.project.common.dto;import com.micromaple.my.project.common.constant.HttpStatus;import java.util.HashMap;/** * 返回结果 * Title: BaseResult * Description: * * @author Micromaple */public class BaseResult extends HashMap<String, Object> {    private static final long serialVersionUID = 1L;    /**     * 状态码     */    public static final String CODE_TAG = "code";    /**     * 返回内容     */    public static final String MSG_TAG = "msg";    /**     * 数据对象     */    public static final String DATA_TAG = "data";    /**     * 初始化一个新创建的 BaseResult 对象，使其表示一个空消息。     */    public BaseResult() {    }    /**     * 初始化一个新创建的 BaseResult 对象     *     * @param code 状态码     * @param msg  返回内容     */    public BaseResult(int code, String msg) {        super.put(CODE_TAG, code);        super.put(MSG_TAG, msg);    }    /**     * 初始化一个新创建的 BaseResult 对象     *     * @param code 状态码     * @param msg  返回内容     * @param data 数据对象     */    public BaseResult(int code, String msg, Object data) {        super.put(CODE_TAG, code);        super.put(MSG_TAG, msg);        super.put(DATA_TAG, data);    }    /**     * 返回成功消息     *     * @return 成功消息     */    public static BaseResult success() {        return BaseResult.success("操作成功");    }    /**     * 返回成功数据     *     * @return 成功消息     */    public static BaseResult success(Object data) {        return BaseResult.success("操作成功", data);    }    /**     * 返回成功消息     *     * @param msg 返回内容     * @return 成功消息     */    public static BaseResult success(String msg) {        return BaseResult.success(msg, null);    }    /**     * 返回成功消息     *     * @param msg  返回内容     * @param data 数据对象     * @return 成功消息     */    public static BaseResult success(String msg, Object data) {        return new BaseResult(HttpStatus.SUCCESS, msg, data);    }    /**     * 返回错误消息     *     * @return     */    public static BaseResult error() {        return BaseResult.error("操作失败");    }    /**     * 返回错误消息     *     * @param msg 返回内容     * @return 警告消息     */    public static BaseResult error(String msg) {        return BaseResult.error(msg, null);    }    /**     * 返回错误消息     *     * @param msg  返回内容     * @param data 数据对象     * @return 警告消息     */    public static BaseResult error(String msg, Object data) {        return new BaseResult(HttpStatus.ERROR, msg, data);    }    /**     * 返回错误消息     *     * @param code 状态码     * @param msg  返回内容     * @return 警告消息     */    public static BaseResult error(int code, String msg) {        return new BaseResult(code, msg, null);    }}

3.4.3、通用工具类

创建工具类包utils。

通用Jackson工具类MapperUtils

package com.micromaple.my.project.common.utils;import com.fasterxml.jackson.annotation.JsonInclude;import com.fasterxml.jackson.databind.DeserializationFeature;import com.fasterxml.jackson.databind.JavaType;import com.fasterxml.jackson.databind.ObjectMapper;import org.apache.commons.lang3.StringUtils;import java.io.IOException;import java.util.ArrayList;import java.util.List;import java.util.Map;/** * Jackson 工具类 * Title: MapperUtils * Description: * * @author Micromaple */public class MapperUtils {    private final static ObjectMapper objectMapper = new ObjectMapper();    public static ObjectMapper getInstance() {        return objectMapper;    }    /**     * 转换为 JSON 字符串     *     * @param obj     * @return     * @throws Exception     */    public static String obj2json(Object obj) {        try {            return objectMapper.writeValueAsString(obj);        } catch (Exception e) {            e.printStackTrace();        }        return "";    }    /**     * 转换为 JSON 字符串，忽略空值     *     * @param obj     * @return     * @throws Exception     */    public static String obj2jsonIgnoreNull(Object obj) throws Exception {        ObjectMapper mapper = new ObjectMapper();        mapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);        return mapper.writeValueAsString(obj);    }    /**     * 转换为 JavaBean     *     * @param jsonString     * @param clazz     * @return     * @throws Exception     */    public static <T> T json2pojo(String jsonString, Class<T> clazz){        objectMapper.configure(DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY, true);        try{            return objectMapper.readValue(jsonString, clazz);        }catch (Exception e){            e.printStackTrace();        }        return null;    }    /**     * 字符串转换为 Map     *     * @param jsonString     * @return     * @throws Exception     */    public static <T> Map<String, Object> json2map(String jsonString){        if(StringUtils.isBlank(jsonString)) return null;        ObjectMapper mapper = new ObjectMapper();        mapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);        try {            return mapper.readValue(jsonString, Map.class);        } catch (IOException e) {            e.printStackTrace();        }        return null;    }    /**     * 深度转换 JSON 成 Map     *     * @param json     * @return     */    public static Map<String, Object> json2mapDeeply(String json) throws Exception {        return json2MapRecursion(json, objectMapper);    }    /**     * 把 JSON 解析成 List，如果 List 内部的元素存在 jsonString，继续解析     *     * @param json     * @param mapper 解析工具     * @return     * @throws Exception     */    private static List<Object> json2ListRecursion(String json, ObjectMapper mapper) throws Exception {        if (json == null) {            return null;        }        List<Object> list = mapper.readValue(json, List.class);        for (Object obj : list) {            if (obj != null && obj instanceof String) {                String str = (String) obj;                if (str.startsWith("[")) {                    obj = json2ListRecursion(str, mapper);                } else if (obj.toString().startsWith("{")) {                    obj = json2MapRecursion(str, mapper);                }            }        }        return list;    }    /**     * 把 JSON 解析成 Map，如果 Map 内部的 Value 存在 jsonString，继续解析     *     * @param json     * @param mapper     * @return     * @throws Exception     */    private static Map<String, Object> json2MapRecursion(String json, ObjectMapper mapper) throws Exception {        if (json == null) {            return null;        }        Map<String, Object> map = mapper.readValue(json, Map.class);        for (Map.Entry<String, Object> entry : map.entrySet()) {            Object obj = entry.getValue();            if (obj != null && obj instanceof String) {                String str = ((String) obj);                if (str.startsWith("[")) {                    List<" />
 
四、创建项目服务模块
 
4.1、创建项目服务模块工程
 
创建一个名称为 my-project-server的项目，该项目负责实现具体业务，以及提供服务。
 
pom.xml内容如下：
 
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">    <modelVersion>4.0.0</modelVersion>    <parent>        <groupId>com.micromaple</groupId>        <artifactId>my-project-dependencies</artifactId>        <version>1.0.0-SNAPSHOT</version>        <relativePath>../my-project-dependencies/pom.xml</relativePath>    </parent>    <artifactId>my-project-server</artifactId>    <packaging>jar</packaging>    <name>my-project-server</name>    <dependencies>                <dependency>            <groupId>com.micromaple</groupId>            <artifactId>my-project-common</artifactId>            <version>1.0.0-SNAPSHOT</version>        </dependency>                        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-test</artifactId>            <scope>test</scope>        </dependency>        <dependency>            <groupId>com.alibaba</groupId>            <artifactId>druid-spring-boot-starter</artifactId>        </dependency>        <dependency>            <groupId>com.baomidou</groupId>            <artifactId>mybatis-plus-boot-starter</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-validation</artifactId>        </dependency>                        <dependency>            <groupId>junit</groupId>            <artifactId>junit</artifactId>            <scope>test</scope>        </dependency>                <dependency>            <groupId>mysql</groupId>            <artifactId>mysql-connector-java</artifactId>        </dependency>                        <dependency>            <groupId>org.apache.poi</groupId>            <artifactId>poi-ooxml</artifactId>        </dependency>            </dependencies>    <build>        <plugins>            <plugin>                <groupId>org.springframework.boot</groupId>                <artifactId>spring-boot-maven-plugin</artifactId>                <configuration>                    <mainClass></mainClass>                </configuration>            </plugin>        </plugins>    </build></project>
4.2、Maven托管
可以使用右侧的Maven 的 + 号来进行项目的托管。
4.3、完善目录结构
创建 src/main/java 和 src/main/resource 目录
在 src/main/java 目录下创建包名，包名为：com.micromaple.my.project.server
在 src/main/resource 目录下创建application.yml，内容如下：
# Spring配置spring:  jackson:    #时间戳统一转换为指定格式    date-format: yyyy-MM-dd HH:mm:ss    # 时区修改为东8区    time-zone: GMT+8server:  port: 8899
4.4、创建 Application
这里使用 Spring 提供的 MyBatis 包扫面注解
package com.micromaple.my.project.server;import org.mybatis.spring.annotation.MapperScan;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication@MapperScan(value = "com.micromaple.my.project.server.mapper")public class MyProjectServerApplication {    public static void main(String[] args) {        SpringApplication.run(MyProjectServerApplication.class, args);    }}
在 pom.xml 中的 mainClass 指定该 Application
<build>        <plugins>            <plugin>                <groupId>org.springframework.boot</groupId>                <artifactId>spring-boot-maven-plugin</artifactId>                <configuration>                    <mainClass>com.micromaple.my.project.server.MyProjectServerApplication</mainClass>                </configuration>            </plugin>        </plugins>    </build>
4.5、整合 Logback
在 src/main/resource 目录下创建logback-spring.xml，内容如下：
<configuration>    <substitutionProperty name="logBase" value="./logs/" />    <substitutionProperty name="logName" value="my-project-server" />    <substitutionProperty name="logPatternExp" value="%date{YYYY-MM-dd HH:mm:ss.SSS} [%-5level] [%thread] %logger{9999} %L -=> %msg%n" />    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">        <encoder>            <pattern>${logPatternExp}</pattern>        </encoder>    </appender>    <appender name="rollingFile" class="ch.qos.logback.core.rolling.RollingFileAppender">        <file>${logBase}${logName}.log</file>        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">            <fileNamePattern>${logBase}${logName}-%d{yyyy-MM-dd}-%i.zip</fileNamePattern>            <maxHistory>180</maxHistory>            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">                <maxFileSize>30MB</maxFileSize>            </timeBasedFileNamingAndTriggeringPolicy>        </rollingPolicy>        <encoder>            <pattern>${logPatternExp}</pattern>        </encoder>    </appender>        <logger name="com.micromaple.my.project.server" level="DEBUG" />    <logger name="org.springframework" level="ERROR" />        <root level="DEBUG">        <appender-ref ref="console" />        <appender-ref ref="rollingFile" />    </root></configuration>
在application.yml增加配置：
logging:  config: classpath:logback-spring.xml
4.6、整合 Druid 数据库连接池
在 src/main/resource 目录下创建application-druid.yml，内容如下：
spring:  datasource:    type: com.alibaba.druid.pool.DruidDataSource    driver-class-name: com.mysql.cj.jdbc.Driver    url: jdbc:mysql://192.168.110.135:3306/my-project?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&serverTimezone=GMT%2B8    username: root    password: 123456    druid:      #连接池配置 初始化连接池的连接数量 大小，最小，最大      initial-size: 5      min-idle: 5      max-active: 20      #配置获取连接等待超时的时间      max-wait: 60000      #配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒      time-between-eviction-runs-millis: 60000      # 配置一个连接在池中最小生存的时间，单位是毫秒      min-evictable-idle-time-millis: 30000      validation-query: SELECT 1 FROM DUAL      test-while-idle: true      test-on-borrow: true      test-on-return: false      # 是否缓存preparedStatement，也就是PSCache  官方建议MySQL下建议关闭   个人建议如果想用SQL防火墙 建议打开      pool-prepared-statements: true      max-pool-prepared-statement-per-connection-size: 20      # 配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙      filter:        stat:          merge-sql: true          slow-sql-millis: 5000      #3.基础监控配置      web-stat-filter:        enabled: true        url-pattern: /*        #设置不统计哪些URL        exclusions: "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*"        session-stat-enable: true        session-stat-max-count: 100      stat-view-servlet:        enabled: true        # 数据监控访问路径        url-pattern: /druid/*        reset-enable: true        #设置监控页面的登录名和密码        login-username: admin        login-password: admin        allow: 127.0.0.1
在 application.yml 增加配置，内容如下：
# Spring配置spring:  # 启用指定配置文件  #（文件名需满足application-{profile}.yml的格式）  profiles:    active: druid
application.yml 完整配置如下：
# Spring配置spring:  jackson:    #时间戳统一转换为指定格式    date-format: yyyy-MM-dd HH:mm:ss    # 时区修改为东8区    time-zone: GMT+8  # 启用指定配置文件  #（文件名需满足application-{profile}.yml的格式）  profiles:    active: druidserver:  port: 8899logging:  config: classpath:logback-spring.xml
最终项目效果图如下：
 
五、创建代码生成模块
5.1、创建代码生成模块工程
创建一个名称为 my-project-generator的项目，该项目负责通过数据库自动生成通用的增删改查。
pom.xml内容如下：
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">    <modelVersion>4.0.0</modelVersion>    <parent>        <groupId>com.micromaple</groupId>        <artifactId>my-project-dependencies</artifactId>        <version>1.0.0-SNAPSHOT</version>        <relativePath>../my-project-dependencies/pom.xml</relativePath>    </parent>    <artifactId>my-project-generator</artifactId>    <packaging>jar</packaging>    <name>my-project-generator</name>    <dependencies>                <dependency>            <groupId>com.micromaple</groupId>            <artifactId>my-project-common</artifactId>            <version>1.0.0-SNAPSHOT</version>        </dependency>                        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-test</artifactId>            <scope>test</scope>        </dependency>        <dependency>            <groupId>com.baomidou</groupId>            <artifactId>mybatis-plus-boot-starter</artifactId>        </dependency>                        <dependency>            <groupId>junit</groupId>            <artifactId>junit</artifactId>            <scope>test</scope>        </dependency>                <dependency>            <groupId>mysql</groupId>            <artifactId>mysql-connector-java</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-mail</artifactId>        </dependency>                                <dependency>            <groupId>org.apache.velocity</groupId>            <artifactId>velocity-engine-core</artifactId>        </dependency>                <dependency>            <groupId>org.freemarker</groupId>            <artifactId>freemarker</artifactId>        </dependency>                        <dependency>            <groupId>com.baomidou</groupId>            <artifactId>mybatis-plus-generator</artifactId>        </dependency>    </dependencies></project>
5.2、Maven托管
可以使用右侧的Maven 的 + 号来进行项目的托管。
5.3、完善目录结构
创建 src/main/java 和 src/main/resource 目录
在 src/main/java 目录下创建包名，包名为：com.micromaple.my.project.generator。
创建代码生成类，内容如下：
package com.micromaple.my.project.generator;import com.baomidou.mybatisplus.generator.FastAutoGenerator;import com.baomidou.mybatisplus.generator.config.DataSourceConfig;import com.baomidou.mybatisplus.generator.config.OutputFile;import com.baomidou.mybatisplus.generator.config.StrategyConfig;import com.baomidou.mybatisplus.generator.config.converts.MySqlTypeConvert;import com.baomidou.mybatisplus.generator.config.querys.MySqlQuery;import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;import com.baomidou.mybatisplus.generator.keywords.MySqlKeyWordsHandler;import java.util.Collections;/** * 代码生成 * Title: GeneratorApplication * Description: * * @author Micromaple */public class GeneratorApplication {    public static void main(String[] args) {        String projectPath = System.getProperty("user.dir");        String finalProjectPath = projectPath + "/my-project-generator";        // 数据源配置        DataSourceConfig.Builder dataSourceConfig = new DataSourceConfig                .Builder(                "jdbc:mysql://192.168.110.135:3306/my-project?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&serverTimezone=GMT%2B8",                "root",                "123456")                .dbQuery(new MySqlQuery())                .typeConvert(new MySqlTypeConvert())                .keyWordsHandler(new MySqlKeyWordsHandler());        new StrategyConfig.Builder()                .serviceBuilder()                .formatServiceFileName("%sService")                .formatServiceImplFileName("%sServiceImp")                .build();        FastAutoGenerator.create(dataSourceConfig)                .globalConfig(builder -> {                    builder.author("Micromaple") //设置作者                            .commentDate("yyyy-MM-dd HH:mm:ss")//注释日期                            .outputDir(finalProjectPath + "/src/main/java"); //指定输出目录                })                .packageConfig(builder -> {                    builder.parent("com.micromaple.my.project.server")                            .moduleName("") // 设置父包模块名                            .entity("domain") //设置entity包名                            //.other("model.dto") // 设置dto包名                            .pathInfo(Collections.singletonMap(OutputFile.mapperXml, finalProjectPath + "/src/main/resources/mapper")); // 设置mapperXml生成路径                })                .strategyConfig(builder -> {                    builder.addInclude("sys_user") // 设置需要生成的表名                            .addTablePrefix("tb_"); // 设置过滤表前缀                    builder.entityBuilder().enableLombok();//开启 lombok 模型                    builder.entityBuilder().enableTableFieldAnnotation();//开启生成实体时生成字段注解                    builder.controllerBuilder().enableRestStyle();//开启生成@RestController 控制器                })                .templateEngine(new FreemarkerTemplateEngine()) // 使用Freemarker引擎模板，默认的是Velocity引擎模板                .execute();    }}
5.4、测试代码生成
建表语句：
CREATE TABLE `sys_user` (  `id` int NOT NULL AUTO_INCREMENT COMMENT '主键',  `code` varchar(100) COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '编号',  `name` varchar(50) COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '姓名',  `sex` varchar(2) COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '性别',  `age` int DEFAULT NULL COMMENT '年龄',  `birthday` date DEFAULT NULL COMMENT '生日',  `mail` varchar(50) COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '邮箱',  `created_date` datetime DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',  `updated_date` datetime DEFAULT NULL COMMENT '更新时间',  PRIMARY KEY (`id`)) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci COMMENT='用户表'
新增数据：
insert into `sys_user` (`code`, `name`, `sex`, `age`, `birthday`, `mail`, `created_date`, `updated_date`) values('admin','超级管理员','男','18','2004-01-01','micromaple@qq.com','2022-09-21 21:48:33',NULL);
执行 GeneratorApplication 类的 main 方法后，可以看到生成的代码，效果如下图：
 
将其拷贝到my-project-server工程模块中，完整效果如下：
 
5.5、测试生成效果
我们在 my-project-server 工程编写单元测试，测试生成的代码是否可用。
创建 src/test/java 目录，在该目录创建包 com.micromaple.my.project.server.service；
接着创建测试类 SysUserServiceTest，内容如下：
package com.micromaple.my.project.server.service;import com.micromaple.my.project.server.MyProjectServerApplication;import com.micromaple.my.project.server.domain.SysUser;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.test.context.SpringBootTest;import org.springframework.test.context.junit4.SpringRunner;import java.util.List;@SpringBootTest(classes = MyProjectServerApplication.class)@RunWith(SpringRunner.class)public class SysUserServiceTest {    @Autowired    private ISysUserService sysUserService;    /**     * 测试新增     */    @Test    public void addTest() {        SysUser sysUser = new SysUser();        sysUser.setCode("user");        sysUser.setName("用户");        sysUser.setSex("女");        sysUser.setAge(18);        boolean save = sysUserService.save(sysUser);        System.out.println(save);        // 输出 true 代表插入成功    }    /**     * 测试查询     */    @Test    public void selectTest() {        List<SysUser> sysUsers = sysUserService.getBaseMapper().selectList(null);        for (SysUser sysUser : sysUsers) {            System.out.println(sysUser.getName());        }        /**         * 输出内容如下：         * 超级管理员         * 用户         */    }}
5.6、测试 Controller 层
SysUserController 代码如下：
package com.micromaple.my.project.server.controller;import com.micromaple.my.project.common.dto.BaseResult;import com.micromaple.my.project.common.utils.MapperUtils;import com.micromaple.my.project.server.domain.SysUser;import com.micromaple.my.project.server.service.ISysUserService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import java.util.List;/** * 
 * 用户表 前端控制器 * 
 * * @author Micromaple * @since 2022-09-21 21:51:15 */@RestController@RequestMapping("/sys-user")public class SysUserController {    @Autowired    private ISysUserService sysUserService;    @GetMapping("/get/all")    public BaseResult getAll() {        List<SysUser> sysUsers = sysUserService.getBaseMapper().selectList(null);        return BaseResult.success(sysUsers);    }}
启动 MyProjectServerApplication 服务，访问地址：
http://localhost:8899/sys-user/get/all
效果如下：
