①:配置Swagger2生成API接口文档

1. 概述

​ 前后端分离开发模式中,api文档是最好的沟通方式。Swagger 是一个规范和完整的框架,用于生成、描述、调用和可视化 RESTful 风格的 Web 服务。及时性 (接口变更后,能够及时准确地通知相关前后端开发人员)规范性 (并且保证接口的规范性,如接口的地址,请求方式,参数及响应格式和错误信息)一致性 (接口信息一致,不会出现因开发人员拿到的文档版本不一致,而出现分歧)可测性 (直接在接口文档上进行测试,以方便理解业务)

2. 配置Swagger2

(1)在classRoom_parent下创建子模块common

(2)在common模块引入依赖 并删除common中的src目录

<dependencies>    <dependency>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-web</artifactId>        <scope>provided </scope>    </dependency>        <dependency>        <groupId>com.baomidou</groupId>        <artifactId>mybatis-plus-boot-starter</artifactId>        <scope>provided </scope>    </dependency>        <dependency>        <groupId>org.projectlombok</groupId>        <artifactId>lombok</artifactId>    </dependency>        <dependency>        <groupId>io.springfox</groupId>        <artifactId>springfox-swagger2</artifactId>    </dependency>    <dependency>        <groupId>io.springfox</groupId>        <artifactId>springfox-swagger-ui</artifactId>    </dependency>    <dependency>        <groupId>com.alibaba</groupId>        <artifactId>fastjson</artifactId>    </dependency></dependencies>

(3)在common下创建子模块service_utils

(4)在service_utils创建swagger2配置类

import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import springfox.documentation.builders.ApiInfoBuilder;import springfox.documentation.service.ApiInfo;import springfox.documentation.service.Contact;import springfox.documentation.spi.DocumentationType;import springfox.documentation.spring.web.plugins.Docket;import springfox.documentation.swagger2.annotations.EnableSwagger2;@Configuration@EnableSwagger2public class Swagger2Config {    @Bean    public Docket webApiConfig(){        return new Docket(DocumentationType.SWAGGER_2)                .groupName("ggkt")                .apiInfo(webApiInfo())                .select()                //只显示api路径下的页面                //.paths(Predicates.and(PathSelectors.regex("/api/.*")))                .build();    }    private ApiInfo webApiInfo(){        return new ApiInfoBuilder()                .title("网站-API文档")                .description("本文档描述了网站微服务接口定义")                .version("1.0")                .contact(new Contact("it", "http://it.com", "it.com"))                .build();    }}

(5)在service模块引入service_utils依赖

<dependency>    <groupId>com.it</groupId>    <artifactId>service_utils</artifactId>    <version>0.0.1-SNAPSHOT</version></dependency>

(6)在service_vod启动类上添加注解,进行测试

@SpringBootApplication@ComponentScan("com.it")public class ServiceVodApplication {    public static void main(String[] args) {        SpringApplication.run(ServiceVodApplication.class, args);    }}

3. 定义接口说明和参数说明

定义在类上:@Api

定义在方法上:@ApiOperation

定义在参数上:@ApiParam

@Api(tags = "讲师管理接口")@RestController@RequestMapping(value="/admin/vod/teacher")public class TeacherController {    @Autowired    private TeacherService teacherService;    //删除讲师    @ApiOperation("逻辑删除讲师")    @DeleteMapping("{id}")    public boolean removeById(@ApiParam(name = "id", value = "ID", required = true) @PathVariable String id){        return teacherService.removeById(id);    }    //查询所有讲师列表    @ApiOperation("所有讲师列表")    @GetMapping("findAll")    public List<Teacher> findAll(){        List<Teacher> list = teacherService.list();        return list;    }}

4. swagger2测试

(1)浏览器输入固定地址 http://localhost:8301/swagger-ui.html

(2)测试接口

(3)执行接口
