PersonServiceBean.java

package com.allen.service.imp;

import com.allen.service.PersonService;

public class PersonServiceBean implements PersonService {
	public String user = "";

	
	public String getUser() {
		return user;
	}

	public PersonServiceBean(){}
	
	public PersonServiceBean(String user){
		this.user=user;
	}
	
        @Override
	public String getPersonName(Integer personid) {
		System.out.println("我是getPersonName()");
		return "AAAAA";
	}

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

        @Override
	public void update(String name) {
		System.out.println("我是update()");
	}

}
PersonService.java
package com.allen.service;

public interface PersonService {
    public void save (String name);
    public void update(String name);
    public String getPersonName(Integer personid);
}

JDKProxyFactory.java
package com.allen.aop;

import java.lang.reflect.InvocationHandler;
import java.lang.reflect.Method;
import java.lang.reflect.Proxy;

import com.allen.service.imp.PersonServiceBean;

public class JDKProxyFactory implements InvocationHandler {
	private Object targeObject;
	
	public Object createProxyIntance(Object targetObject){
		this.targeObject = targetObject;
		return Proxy.newProxyInstance(this.targeObject.getClass().getClassLoader(),
				this.targeObject.getClass().getInterfaces(), this);
	}

	@Override
	public Object invoke(Object proxy, Method method, Object[] args)
			throws Throwable {
		PersonServiceBean bean = (PersonServiceBean) this.targeObject;
		Object result =null;
		if(bean.getUser()!=""){
			result  = method.invoke(targeObject, args);
		}
		return result;
	}
}

这是测试用的 junit4
AopTest.java

package junit.test;


import org.junit.BeforeClass;
import org.junit.Test;

import com.allen.aop.CGLibFactory;
import com.allen.aop.JDKProxyFactory;
import com.allen.service.PersonService;
import com.allen.service.imp.PersonServiceBean;

public class AopTest {

	@BeforeClass
	public static void setUpBeforeClass() throws Exception {
	}
	
	@Test public void proxyTest(){
		JDKProxyFactory factory = new JDKProxyFactory();
		PersonService service = (PersonService) factory.createProxyIntance(new PersonServiceBean("asf"));
		service.save("888");
	}
}

不管评论什么 我都接受！！！
