SpringBoot整合mybatis时，启动报错：

**Field userMapper in com.csf.controller.UserController required a bean of type ‘com.csf.mapper.UserMapper’ that could not be found.
The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type ‘com.csf.mapper.UserMapper’ in your configuration.
Process finished with exit code 1
**
找不到UserMapper这个接口，具体原因，UserMapper没有被IOC容器扫描到，我的包导入的都是正确的，唯一没有弄好的时springboot启动器上面没有添加注解，具体映射扫描到UserMapper所在的包。

添加@MapperScan()

@SpringBootApplication
@MapperScan("com.csf.mapper")
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class,args);
    }
}

OK！
稍微记录一下！
