使用Spring框架進行J2SE程序設計(一).doc

實驗4 AOP一、實驗目的1. 掌握創(chuàng)建增強類和切面類的方法2. 掌握基于AspectJ注解的AOP3. 掌握基于XML配置文件的AOP二、實驗器材1. 計算機三、實驗內(nèi)容1. 創(chuàng)建Waiter接口和NaiveWaiter類2. 定義切面類以及前置增強和后置增強，并織入到greetTo()方法3. 使用AspectJ注解和XML配置文件兩種方式四、實驗步驟1.創(chuàng)建Waiter接口package com.myw.spring3;public interface Waiter public void greetTo();2 創(chuàng)建NaiveWaiter類package com.myw.spring3;public class NaiveWaiter implements WaiterOverridepublic void greetTo() System.out.println(hello);3 創(chuàng)建切面類package com.myw.spring2;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Before;Aspectpublic class GreetAspect Before(execution(* greetTo(.) public void beforeGreet() System.out.println(before); 4 編寫配置文件 5 編寫測試類package com.myw.spring2;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class TestAnno public static void main(String args) ApplicationContext cnt = new ClassPathXmlApplicationContext(spring1.xml); Waiter waiter = (Waiter) cnt.getBean(waiter); waiter.greetTo(); 6運行結果截圖7 xml方式的切面類package com.myw.spring3;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Before;Aspectpublic class GreetAspect public void beforeGreet() System.out.println(befor
