1、java代码

@Test

public void testSchemaAroundAdvice() {

System.out.println("======================================");

long start = System.currentTimeMillis();

ApplicationContext ctx = new ClassPathXmlApplicationContext("chapter6/advice.xml");

IHelloWorldService helloworldService = ctx.getBean("helloWorldService", IHelloWorldService.class);

helloworldService.sayAround("haha");

System.out.println("======================================");

long end = System.currentTimeMillis();

System.out.println("end!        performance took "+(end-start)+" milliseconds");

}

2、advice.xml中

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:context="http://www.springframework.org/schema/context"

xmlns:aop="http://www.springframework.org/schema/aop"

xsi:schemaLocation="

http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/aop

advice-ref="beforeAdvice"/>

method="beforeAdvice(java.lang.String)"

method="afterReturningAdvice"

arg-names="retVal"

method="afterThrowingAdvice"

method="afterFinallyAdvice"/>

method="aroundAdvice"/>

implement-interface="cn.javass.spring.chapter6.service.IIntroductionService"

default-impl="cn.javass.spring.chapter6.service.impl.IntroductiondService"/>

3、切面中的 方法

public Object aroundAdvice(ProceedingJoinPoint pjp) throws Throwable {

System.out.println("===========around before advice");

Object retVal = pjp.proceed(new Object[] {"replace"});

System.out.println("===========around after advice");

return retVal;

}
