Spring的AOP应用实例

/**
 * 实现org.springframework.aop.MethodBeforeAdvice
 */
public class WelcomeAdvice implements MethodBeforeAdvice{
    public void before(Method method, Object[] objects, Object o) throws Throwable {
        System.out.println("Welcome,这是MethodBeforeAdvice的before方法!");
    }
}

/**
 *实现了org.springframework.aop.AfterReturningAdvice
 */ 
public class ThankYouAdvice implements AfterReturningAdvice{
    public void afterReturning(Object o, Method method, Object[] objects, Object o1) throws Throwable {
        System.out.println("Thank you, come again!  这是 AfterReturningAdvice的afterReturning方法！");
    }
}

public interface IAopTest {
    void test();
}
public class AopTest implements IAopTest{
    public void test() {
        System.out.println("Aop Testing.......");
    }
}

public class TestResultImpl {
    private IAopTest aopTest;
    public void setAopTest(IAopTest aopTest) {
        this.aopTest = aopTest;
    }
    public void test() {
        aopTest.test();
    }
}

/**

 */
public class MyTest {
    @Test
    public void test() {
        ApplicationContext ctx = new ClassPathXmlApplicationContext(new String[] {"aop/test.xml"});
        TestResultImpl aopTest = (TestResultImpl)ctx.getBean("testResult");
        aopTest.test();
    }
}

这是测试结果：

Welcome,这是MethodBeforeAdvice的before方法!
Aop Testing.......
Thank you, come again! 这是AfterReturningAdvice的afterReturning方法！

有源码吗？按你的操作写了，不能运行！
