1.导入相关的依赖

 
    
        org.springframework.boot
        spring-boot-starter
         
            
                org.springframework.boot

        org.apache.logging.log4j
        log4j-core
    
    
    
        org.apache.logging.log4j
        log4j-api
    
    
    
        org.apache.logging.log4j

        org.slf4j
        slf4j-api

        log4j
        log4j
        1.2.12
    

2.log4j2 日志文件

3.dao层的接口以及实现类

文件路径：com.dzj.dao.Userdao.java

package com.dzj.dao;
 
public interface Userdao {
 
    void add();
 
    void update();
 
    void delete();
 
    void query();
}

文件路径：com.dzj.dao.UserDaoImpl.java

package com.dzj.dao;
 
import org.springframework.stereotype.Service;
 
@Service
public class UserDaoImpl implements Userdao {
    @Override
    public void add() {
        System.out.println("执行了添加方法...");
    }
 
    @Override
    public void update() {
 
        System.out.println("执行了修改方法...");
    }
 
    @Override
    public void delete() {
 
        System.out.println("执行了删除方法...");
    }
 
    @Override
    public void query() {
 
        System.out.println("执行了查找方法...");
    }
}

4.Service层业务实现类

文件路径：com.dzj.service.UserService.java

package com.dzj.service;
 
import com.dzj.dao.UserDaoImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
 
@Service
public class UserService {
 
    @Autowired
    UserDaoImpl userDao;
 
    public void add(){
        userDao.add();
    }
    public void update(){
        userDao.update();
    }
    public void delete(){
        userDao.delete();
    }
    public void query(){
        userDao.query();
    }
}

5.Controller层接口控制类

文件路径：com.dzj.controller.UserController.java

package com.dzj.controller;
 
import com.dzj.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
 
@Controller
@ResponseBody
public class UserController {
 
    @Autowired
    UserService userService;
 
    @RequestMapping("/test")
    public String userTest(){
 
        userService.add();
        return "chenggongle...";
    }
}

6.编写业务类增强类，加入一个日志文件记录

package com.dzj.advice;
 
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestAttributes;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;
 
import javax.servlet.http.HttpServletRequest;
import java.util.Arrays;
 
@Component
@Aspect
public class AdviceMethod {
 
    private static final Logger log = LoggerFactory.getLogger(AdviceMethod.class);
 
    @Pointcut("execution(public * com.dzj.service.UserService.*(..))")
    public void webLog(){}
 
    @Before("webLog()")
    public void before(JoinPoint joinPoint){
 
        //这个RequestContextHolder是Springmvc提供来获得请求的东西
        RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = ((ServletRequestAttributes)requestAttributes).getRequest();
 
        // 记录下请求内容
        log.info("################URL : " + request.getRequestURL().toString());//获取请求的地址
        log.info("################HTTP_METHOD : " + request.getMethod());//获取请求的方法
        log.info("################IP : " + request.getRemoteAddr());
        log.info("################THE ARGS OF THE CONTROLLER : " + Arrays.toString(joinPoint.getArgs()));
 
        /**
         * getSignature().getDeclaringTypeName()   是获取包+类名的
         * joinPoint.getSignature.getName()  获取了方法名
         * joinPoint.getTarget() 返回的是需要加强的目标类的对象
         * joinPoint.getThis())  返回的是经过加强后的代理类的对象
         */
        log.info("################CLASS_METHOD : " + joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName());
        log.info("################TARGET: " + joinPoint.getTarget());
        log.info("################THIS: " + joinPoint.getThis());
        System.out.println("方法执行之前...");
    }
 
    @After("webLog()")
    public void after(){
        System.out.println("方法执行之后...");
    }
}

7.运行测试，查看结果

启动主启动器类，在浏览器中输入http://localhost:8080/test，查看控制台输出信息
