动态切换数据源

so-fast框架支持基于注解的动态数据源切换功能。默认只支持主从库。

使用方式如下：

• 配置文件配置主从DB

   # 数据源配置
   spring:
     datasource:
       type: com.alibaba.druid.pool.DruidDataSource
       driverClassName: com.mysql.cj.jdbc.Driver
       druid:
         # 主库数据源
         master:
           url: jdbc:mysql://xxxx:3306/so-fast?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT%2B8
           username: username
           password: password
         # 从库数据源
         slave:
           # 从数据源开关/默认关闭
           enabled: false
           url:
           username:
           password:
  

• 通过注解切换DB

  在Controller或Service的类或方法上添加注解。例如：读写分离场景

   @DynamicDS(value = DataSourceType.SLAVE)
   @ApiOperation(value = "查询操作日志")
   @LogOperator(title = "查询操作日志", type = Constants.SELECT_OPERATOR)
   @GetMapping(value = "/")
   public R<Page<OperatorLog>> list(OperatorLogQueryVo operatorLogQueryVo) {
  
   @DynamicDS(value = DataSourceType.MASTER)
   @ApiOperation(value = "根据ID删除日志")
   @LogOperator(title = "日志删除", type = Constants.DELETE_OPERATOR)
   @PostMapping(value = "/delete/{ids}")
   public R delete(@PathVariable Long[] ids) {
