業(yè)務(wù)Bean，接口就不貼了

package cn.itcast.service.impl;

import cn.itcast.service.PersonService;

public class PersonServiceBean implements PersonService {

public String getPersonName(Integer id) {
System.out.println("我是getPersonName()方法");
return "XXX";
}

public void save(String name) {
System.out.println("我是save()方法");
}

public void update(String name, Integer id) {
System.out.println("我是update()方法");
}

}

實(shí)現(xiàn)AOP的類　

package cn.itcast.service;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;

@Aspect
public class MyInterceptor {
@Pointcut("execution (* cn.itcast.service.impl.PersonServiceBean.*(..))")
private void anyMethod() {}

@Before("anyMethod()")
public void doAccessCheck(String userName) {
System.out.println("前置通知");
}
}

測試方法

package junit.test;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import cn.itcast.service.PersonService;

public class SpringAOPTest {
@Test
public void interceptorTest(){
ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");
PersonService personService = (PersonService)ctx.getBean("personService");
personService.save("xxx");
}
}
