容器未找到bean，Field usersMapper in com.imooc.impl.UserServiceImpl required a bean of type 'com.imoo

启动报未找到相关的实体类错误

Description:

Field usersMapper in com.imooc.impl.UserServiceImpl required a bean of type 'com.imooc.mapper.UsersMapper' 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.imooc.mapper.UsersMapper' in your configuration.

　原因可是是启动类扫描包范围问题，需要加上对应报错类的包路径的注解

import tk.mybatis.spring.annotation.MapperScan;

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