若依-更换数据库-sqlite

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

2.application-druid.yml

2.1

# 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

	# 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mysql
		paginationInnerInterceptor.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.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
