基础

我是在ruoyi-vue已经安装了mybatis-plus的基础上进行的修改

关于SQLite

SQLite 是一个软件库，实现了自给自足的、无服务器的、零配置的、事务性的 SQL 数据库引擎。
SQLite主页：https://www.sqlite.org/index.html

1. pom.xml

  org.springframework.boot  spring-boot-starter-web  org.projectlombok  lombok  true  org.xerial  sqlite-jdbc  3.21.0.1  com.baomidou  mybatis-plus-boot-starter  3.4.3.1

2.application-druid.yml2.1 配置驱动

# 数据源配置spring:    datasource:        type: com.alibaba.druid.pool.DruidDataSource        driverClassName: org.sqlite.JDBC        druid:            # 主库数据源            master:                url: jdbc:sqlite:db\\db.sqlite3?date_string_format=yyyy-MM-dd HH:mm:ss                username:                password:

注意： date_string_format=yyyy-MM-dd HH:mm:ss 必须添加否则有时会导致查询是报错

Caused by: java.sql.SQLException: Error parsing time stamp

2.2 修改初始化时校验是否连接成功查询

# 配置检测连接是否有效validationQuery: SELECT 1 FROM sys_config

3.MybatisPlusConfig

/** * 分页插件，自动识别数据库类型 https://baomidou.com/guide/interceptor-pagination.html */public PaginationInnerInterceptor paginationInnerInterceptor(){PaginationInnerInterceptor paginationInnerInterceptor = new PaginationInnerInterceptor();// 设置数据库类型为mysqlpaginationInnerInterceptor.setDbType(DbType.SQLITE);// 设置最大单页限制数量，默认 500 条，-1 不受限制paginationInnerInterceptor.setMaxLimit(-1L);return paginationInnerInterceptor;}

4. 修改因为mapper中使用sysdate() 报错问题4.1 BaseEntity

    /** 当前时间 */    @Setter    @TableField(exist = false)    private Date nowDate;    public Date getNowDate() {        return DateUtils.getNowDate();    }

4.2 修改mapper

SysLogininforMapper.xmlinsert into sys_logininfor (user_name, status, ipaddr, login_location, browser, os, msg, login_time) values (#{userName}, #{status}, #{ipaddr}, #{loginLocation}, #{browser}, #{os}, #{msg}, #{nowDate})SysUserMapper.xmlremark = #{remark},update_time = #{nowDate}where user_id = #{userId}

5.mysql表数据结构转移为sqlite表结构及数据

我在这里分享一份我整理好的 可能版本会有点旧 到时候缺字段在补充吧链接：https://pan.baidu.com/s/19UFOhYv0qTpRZgoAsjFj2g 提取码：pwc2

把数据库文件放到这里就可以了
