Unsatisfied dependency expressed through field 'baseMapper'

使用MyBatisX自动生成Mapper接口，启动springboot项目时却报错

Error creating bean with name 'commentServiceImpl': Unsatisfied dependency expressed through field 'baseMapper';
...

• 原因：
  自动生成的Mapper接口没有被扫描到
• 解决方法
  1. 给每个Mapper接口添加@Mapper注解
  2. 或添加一个配置类，用@MapperScan注解扫描Mapper所在包名

@Configuration
@MapperScan("com.xxx.mappper")
public class MyBatisPlusConfig {
}
