軟件測測之框架：一個使用spring框架AOP的有趣例子

            < value>com.denny_blue.springdemo.aop.BuyBook< /value>
        < /property>
        < property name="interceptorNames">
            < list>
                  < value>myBeforeAdvice< /value>
                  < value>myAfterAdvice< /value>
                  < value>myAroundAdvice< /value>
                  < value>myThrowsAdvice< /value>
            < /list>
        < /property>
        < property name="target">
            < ref bean="myBuyBookTarget"/>
        < /property>
     < /bean>
< /beans>

我們先聲明所有的bean，通過

 < bean id="myBuyBookTarget" class="com.denny_blue.springdemo.aop.MyBuyBook"/>
確定將要被增強的對象??目標對象(target)，我們可以很容易地替換這個目標對象，只要它實現業務接口。代理的接口通過:

< property name="proxyInterfaces">
            < value>com.denny_blue.springdemo.aop.BuyBook< /value>
< /property>
設定，然后是要用到一系列增強，注意，順序是很有影響的！你可以嘗試著改變順序看看結果：）

< property name="interceptorNames">
            < list>
                  < value>myBeforeAdvice< /value>
                  < value>myAfterAdvice< /value>
                  < value>myAroundAdvice< /value>
                  < value>myThrowsAdvice< /value>
            < /list>
< /property>

一切準備好了，我們來測試吧，GO GO GO

package test;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

import com.denny_blue.springdemo.aop.BuyBook;

public class TestAdvice {
 public static void main(String args[]){
  ApplicationContext ctx=new FileSystemXmlApplicationContext("/src/beans.xml"); 

  //我的beans.xml放在項目下的src目錄，eclipse環境下，請自己調整
  BuyBook buybook=(BuyBook)ctx.getBean("buyBook");
  buybook.buyBook("jordan","< 深入淺出hibernate>");
  // buybook.buyBook("dennis","< spring in action>");    //去掉注釋即可觀察異常增強
 // buybook.buyBook("jordan","< 深入淺出hibernate>");   //去掉注釋即可觀察環繞增強

 }
}
