1.导入相关的依赖

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.adyPZyDd();

}

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
