Spring2.5学习笔记2-AOP-利用注解

一、AspectJProxyFactory
XML文件：

     < bean id ="helloWorldDao" class ="cn.aop.aspect.dao.HelloWorldDaoImpl"   p:helloworld ="helloworldDao" />
   < bean id ="helloworldService" class ="cn.aop.aspect.service.HelloWorldServiceImpl"     p:helloWorldDao-ref ="helloWorldDao" />

java Main 函数

  ListableBeanFactory factory    = new ClassPathXmlApplicationContext( "aspectAop.xml");
    GenericBeanFactoryAccessor gbf = new GenericBeanFactoryAccessor(factory);
    IHelloWorldService hw = gbf.getBean( "helloworldService");
    log.info(hw.getContext( "哈哈"));
    log.info( "==========================before==============================");
    AspectJProxyFactory ajpFactory = new AspectJProxyFactory(gbf.getBean( "helloworldService"));
    ajpFactory.addAspect(LoggingBeforeAspect. class);
    IHelloWorldService hw2 = ajpFactory.getProxy();
    log.info(hw2.getContext( "哈哈"));

输出：

AspectAOPMain(AspectAOPMain.java:27) -0        [main]    - helloworldDao    哈哈
AspectAOPMain(AspectAOPMain.java:28) -2        [main]    - ==========================before==============================

LoggingBeforeAspect(LoggingBeforeAspect.java:22) -219    [main]    - 哈哈
LoggingBeforeAspect(LoggingBeforeAspect.java:23) -219    [main]    - cn.aop.aspect.service.HelloWorldServiceImpl@7a1576
LoggingBeforeAspect(LoggingBeforeAspect.java:24) -219    [main]    - cn.aop.aspect.service.HelloWorldServiceImpl@7a1576
AspectAOPMain(AspectAOPMain.java:32) -220    [main]    - helloworldDao    哈哈
