SpringBoot 集成Mybatis时 使用通用插件Mapper 注意事项
1、如果在SpringBoot的启动入口类上面加入注解
@MapperScan(basePackages = "com.leecx.mapper") 使用的是 org.mybatis.spring.annotation.MapperScan;
那么在使用通用Mapper插件的时候 会报错 信息如下：

对于 这种报错 解决方法如下：
在SpringBoot的启动入口类上面加入注解 由原来的
@MapperScan(basePackages = "com.leecx.mapper") 使用的是 org.mybatis.spring.annotation.MapperScan;
改为
@tk.mybatis.spring.annotation.MapperScan(basePackages = "com.leecx.mapper") 使用的是 tk.mybatis.spring.annotation.MapperScan
可以避免如上错误信息
