基于XML的Spring AOP

Spring版本: Spring3.0

1. IUserService.java

package com.lk.springdi.service;

import com.lk.springdi.model.User;

public interface IUserService {
    
    int addUser(User user);
    
    void deleteUser(User user);

}

UserServiceImpl.java

package com.lk.springdi.service.impl;

import javax.annotation.Resource;
import org.springframework.stereotype.Service;

import com.lk.springdi.dao.IUserDao;
import com.lk.springdi.model.User;
import com.lk.springdi.service.IUserService;

@Service("userService")
public class UserServiceImpl implements IUserService {
    private IUserDao userDao;

    @Override
    public int addUser(User user) {
        userDao.add(user);
        return 0;
    }

    @Override
    public void deleteUser(User user) {
        System.out.println("delete user");
    }

    public IUserDao getUserDao() {
        return userDao;
    }
    
    @Resource
    public void setUserDao(IUserDao userDao) {
        this.userDao = userDao;
    }
}

切面类: LogIntercepter.java

package com.lk.springdi.aop;

public class LogIntercepter {
    
    public void beforeMethod() {
        System.out.println("do some thing before method");
    }
    
    public void afterMethod() {
        System.out.println("do some thing after method");
    }
}

测试

@Test
    public void test1() {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
        IUserService userService = (IUserService) applicationContext.getBean("userService");
        User user = new User();
        userService.deleteUser(user);
    }
