SpringAOP 的使用（两种方式）

 使用Spring AOP 拦截 方法，给被拦截的方法加上，前置通知，后置通知，例外通知，最终通知 的两个例子，见 附件

需要 spring.jar，cglib.jar，commons-logging.jar

 

方式1. 被拦截的类没有实现任何接口

 

关键代码：

package junit.test;
import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.aop.framework.ProxyFactoryBean;
import org.springframework.aop.support.DefaultPointcutAdvisor;

import cn.com.xinli.common.BusinessMethodInterceptor;
import cn.com.xinli.service.BusinessInterface;
import cn.com.xinli.service.impl.BusinessImpl;
/*springAOP 测试方式1 的测试用例 只需要spring.jar 支持
 * 
 * */
public class AOPTest
{
	static BusinessInterface face=null;
	@BeforeClass
	public static void setUpBeforeClass() throws Exception
	{
		BusinessImpl bi=new BusinessImpl();
		ProxyFactoryBean proxyFactoryBean = new ProxyFactoryBean();
		proxyFactoryBean.setTarget(bi);
		proxyFactoryBean.addAdvisor(new DefaultPointcutAdvisor(new BusinessMethodInterceptor()));
		proxyFactoryBean.setInterfaces(new Class[]{BusinessInterface.class});
		face= (BusinessInterface)proxyFactoryBean.getObject();
	}

	@Test
	public void testAdd() throws Exception
	{
		
		
		
		face.add();
	}

	@Test
	public void testDel()
	{
		face.del();
	}

	@Test
	public void testFind()
	{
		face.find();
	}

	@Test
	public void testUpdate()
	{
		face.update();
	}

}

 

方式2. 被拦截的类没有实现任何接口

 

关键代码：

package junit.test;
import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.aop.framework.ProxyFactory;
import org.springframework.aop.framework.ProxyFactoryBean;
import org.springframework.aop.support.DefaultPointcutAdvisor;

import cn.com.xinli.common.BusinessMethodInterceptor;
import cn.com.xinli.service.impl.Business;
/*springAOP 测试方式2 的测试用例 需要spring.jar和cglib.jar 支持
 * 
 * */
public class AOPTest2
{
	static Business business =null;
	@BeforeClass
	public static void setUpBeforeClass() throws Exception
	{
				/**/
				ProxyFactoryBean proxyFactoryBean = new ProxyFactoryBean();
				proxyFactoryBean.addAdvisor(new DefaultPointcutAdvisor( new BusinessMethodInterceptor()));
				proxyFactoryBean.setTarget(new Business());
				business = (Business) proxyFactoryBean.getObject();
	}

	@Test
	public void testAdd() throws Exception
	{
		/*另一种调用方式*/
		Business target = new Business();
        ProxyFactory pf = new ProxyFactory();
        pf.addAdvice(new BusinessMethodInterceptor()); 
        pf.setTarget(target);
        Business proxy = (Business) pf.getProxy();
        //输出代理对象调用的信息
         proxy.add();    
	}

	@Test
	public void testDel()
	{
		business.del();
	}

	@Test
	public void testFind()
	{
		business.find();
	}

	@Test
	public void testUpdate()
	{
		business.update();
	}

}
