设置日志注解：

@Target({ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface BusinessOption {
String moduleName() default "";
String menuName() default "";

}

HelloWorld:

package cn.jzj;




import java.util.Map;


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;






@Controller("/Hello")
@RequestMapping("/Hello")
@Configuration
public class Helloworld {

@Autowired  
private UserMapper userMapper;
@BusinessOption(moduleName="的说法都是", menuName="谁不是")
@RequestMapping(value="/hello")
public String helloWorld() {

return "success";
}

}

UserMapper.java:

import java.util.List;


public interface UserMapper {
void save(User user);
void update(User user);
void delete(int id);
User findById(int id);
List findAll();

}

UserMapper.xml:

insert into user_log(name,desc1)
values(#{name},#{desc})




update user_log
set name = #{name},
desc1 = #{desc},
where id = #{id}



delete from user_log
where id = #{id}




select *
from user_log
where id = #{id}



select * 
from user_log
