背景：记录aop的使用方式。aop相关术语概念自行了解清楚，以下仅贴示例。
spring 版本：5.0.8.RELEASE
相关jar包，参考一下附件pom.xml

DAO
bean

package com.spring.aop.dao.bean;
public class User {
    private String name;
    private int age;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
}

dao

package com.spring.aop.dao.dao;
import com.spring.aop.dao.bean.User;
public interface UserDao {
	void add(User user);
	User queryByName(String name);
}

daoimpl

package com.spring.aop.dao.impl;
import com.spring.aop.dao.bean.User;
import com.spring.aop.dao.dao.UserDao;
public class UserDaoImpl implements UserDao {
	public void add(User user) {
		System.out.println("添加用户，姓名：" + user.getName() + "，年龄：" + user.getAge());
	}
	public User queryByName(String name) {
		System.out.println("DAO查询："+name);
		if("test".equals(name))
		{
			User user=new User();
			user.setName("test");
			user.setAge(18);
			return user;
		}else{
			return null;
		}
	}
}

Service

package com.spring.aop.service;
import com.spring.aop.dao.bean.User;
import com.spring.aop.dao.dao.UserDao;
public class UserService {
	private UserDao userDao;
	public void setUserService(UserDao userDao){
		this.userDao = userDao;
	}
	public  void addUser(User user) {
		userDao.add(user);
	}
	public User queryByName(String name){
		return userDao.queryByName(name);
	}
}

controller

package com.spring.aop.controller;
import com.spring.aop.dao.bean.User;
import com.spring.aop.service.UserService;
public class UserController {
	private UserService userService;
	public UserController(UserService userService){
		this.userService = userService;
	}
	public  void addUser(User user) {
		userService.addUser(user);
	}
	public User queryByName(String name) {
		return userService.queryByName(name);
	}
}

通知advice

package com.spring.aop.advice;
import com.spring.aop.dao.bean.User;
import org.aspectj.lang.ProceedingJoinPoint;
/**
 * 切面的工作 - 通知
 */
public class TestAdvice {
    public void before(){
        System.out.println("方法执行前执行...");
    }
    //调用方法后的返回值 - 在方法切之后执行
    public void returning(Object object){
        System.out.println("###方法返回之后的处理###" + (object==null ? "无数据" : object));
        if (object instanceof User){
            User user = (User) object;
            user.setName("你的名字被修改了！");
            System.out.println("#方法返回之后，处理完成");
        }
    }
    public void after(){
        System.out.println("方法执行之后执行...");
        System.out.println();
    }
    //环绕，在before和after之间执行
    public Object round(ProceedingJoinPoint point) throws Throwable {
        System.out.println("******before方法之前******");
        Object o = point.proceed();//调用对应方法
        System.out.println("******after方法之后******");
        return o;
    }
    public void throwing(Exception e) {
        System.out.println("方法出现异常时执行："+e.getMessage());
    }
}

test main

package com.spring.aop.main;
import com.spring.aop.controller.UserController;
import com.spring.aop.dao.bean.User;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Test {
	public static void main(String[] args) {
		ApplicationContext context=new ClassPathXmlApplicationContext("springaop.xml");
		UserController userController =context.getBean("userController", UserController.class);
//		UserDao userDao =context.getBean("userDaoImpl", UserDaoImpl.class);
		User user=new User();
		user.setAge(22);
		user.setName("AOP Test");
		userController.addUser(user);
		userController.queryByName("test");
	}
}

aop xml的配置
