Spring AOP概念学习（四）-基于schema的aop支持
看了文档，基于@JAspect支持的Spring AOP不知什么原因，编写相关的例子程序，没有运行成功，所以暂时不能写出来供大家交流，如果调试出来后，一定补上。现在先来看看Spring中另一种AOP的支持-基于Schema的AOP支持。
和以前一样，还是先把例子程序写出来，有什么注意的地方会在稍后注明。
1、通知
package com.javaeye.sunjiesh.aop.aspect;public class AspectExample {/** * 前置通知（Before advice） */public void beforeAdvice() {System.out.println("beforeAdvice");}/** * 带参数的前置通知（Before advice） * @param parameter */public void beforeAdvice2(String parameter){System.out.println("beforeAdvice2");System.out.println("parameter is "+parameter);}/** * 后通知（After (finally) advice） */public void afterAdvice() {System.out.println("afterAdvice");}/** * 返回后通知（After returning advice） * @param parameter 连接点运行后返回的参数 */public void afterReturnAdvice(String parameter) {System.out.println("afterReturnAdvice");System.out.println("parameter is "+parameter);}/** * 抛出异常后通知（After throwing advice） * @param ex 连接点运行时发生的异常 */public void afterThrowingAdvice(Exception ex) {System.out.println("afterThrowingAdvice");System.out.print(ex.getMessage());}/** * 环绕通知（Around Advice） */public void aroundAdvice() {System.out.println("aroundAdvice");}} 2、连接点
package com.javaeye.sunjiesh.aop.aspect;public class ServiceExample {public void adviceTest(){System.out.println("adviceTest is run");}public String adviceTest2(){System.out.println("adviceTest2 is run");try {throw new Exception();} catch (Exception e) {// TODO Auto-generated catch block//e.printStackTrace();System.out.println(e.getMessage());}finally{return null;}}} 3、spring配置文件

4、主函数
package com.javaeye.sunjiesh.aop.aspect;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class AspectMain {public static void main(String args[]) {ApplicationContext ctx = new ClassPathXmlApplicationContext("spring-beans4.xml");ServiceExample serviceExample=(ServiceExample) ctx.getBean("serviceExample");serviceExample.adviceTest();serviceExample.adviceTest2();System.out.println("使用通知参数");ServiceExample2 serviceExample2=(ServiceExample2) ctx.getBean("serviceExample2");serviceExample2.adviceTest("hello");}}
