Spring AOP 中的控制流切入點

1 控制流切入點

          匹配一個類的某一個方法或該方法下的所有方法調用。

。實現代碼如下：

package cuigh.spring.aop.step02;

import org.aopalliance.aop.Advice;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.aop.Advisor;
import org.springframework.aop.Pointcut;
import org.springframework.aop.framework.ProxyFactory;
import org.springframework.aop.support.ControlFlowPointcut;
import org.springframework.aop.support.DefaultPointcutAdvisor;
/**
 * 功能：演示控制流切入點使用
 */
public class ControlFlowPointcutExample {
	
	static Log log = LogFactory.getLog(ControlFlowPointcutExample.class);

	public static void main(String[] args) {

		//創建目標
		TestControlFlowPointcut target = new TestControlFlowPointcut();
		//創建 通知 
		Advice advice = new MyBeforeAdvice();
		//創建切入點 MyDynamicPointcut 方法 testNotAdvice（） 被攔截
		Pointcut pointcut = new ControlFlowPointcut(TestControlFlowPointcut.class,"testNotAdvice");
		//創建通知者
		Advisor  advisor = new DefaultPointcutAdvisor(pointcut,advice);
		
		//創建代理
		ProxyFactory pf = new ProxyFactory();
		pf.setTarget(target);
		pf.addAdvisor(advisor);
		TestControlFlowPointcut proxy = (TestControlFlowPointcut)pf.getProxy();
		
		log.info("-----下面未被攔截------");
		target.test(proxy);
		log.info("-----下面被攔截------");
		target.testNotAdvice(proxy);

	}
}

package cuigh.spring.aop.step02;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
/*
 * 功能：控制流切入點示例類
 * */
public class TestControlFlowPointcut {
	static Log log = LogFactory.getLog(TestControlFlowPointcut.class);

	public void test1(){
		log.info(this.getClass().getName()+".test1()");
	}
	
	public void test2(){
		log.info(this.getClass().getName()+".test2()");
	}
	
	public void test(TestControlFlowPointcut bean){
		bean.test1();
		bean.test2();
	}
	//對此方法進行攔截
	public void testNotAdvice(TestControlFlowPointcut bean){
		bean.test1();
		bean.test2();
	}
}

package cuigh.spring.aop.step02;

import java.lang.reflect.Method;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.aop.MethodBeforeAdvice;

public class MyBeforeAdvice implements MethodBeforeAdvice {

	static Log log = LogFactory.getLog(MyBeforeAdvice.class);
	@Override
	public void before(Method method, Object[] args, Object target)
			throws Throwable {
		log.info("方法執行前攔截，被攔截方法="+method.getName());
	}
}

程序輸出：
