我的代碼= >>>

Hero.java：

package codes; 

public class Hero { 

    Knife knife; 

    public Hero(Knife knife) 
    { 
     this.knife=knife; 
    } 
    public Knife getKnife() { 
     return knife; 
    } 
}

Knife.java

package codes; 

public class Knife { 

    public void kill() 
    { 
     System.out.println("Killed!"); 
    } 
}

小號inger.java：

包裝碼;

public class Singer { 

    public void beforeKill() 
    { 
     System.out.println("cha chah..before kill"); 
    } 
    public void afterKill() 
    { 
     System.out.println("cha cha..after kill"); 
    } 
}

aspect.xml：

<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd 
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"> 


<bean id="knifeBean" class="codes.Knife"></bean> 

<bean id="SingerBean" class="codes.Singer"></bean> 

<bean id="HeroBean" class="codes.Hero"> 
<constructor-arg ref="knifeBean"></constructor-arg> 
</bean> 

<aop:config> 
<aop:aspect ref="SingerBean"> 
<aop:pointcut expression="execution(* *.kill(..))" id="SingerPointCut"/> 
<aop:before method="beforeKill" pointcut-ref="SingerPointCut"/> 
<aop:after method="afterKill" pointcut-ref="SingerPointCut"/> 
</aop:aspect> 
</aop:config> 

</beans>

測試類：

package codes; 

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

public class Test { 

    public static void main(String[] args) { 
     System.err.println("start.."); 
     ApplicationContext ac=new ClassPathXmlApplicationContext("codes/aspect.xml"); 
     System.out.println(ac); 
     Hero sina=(Hero)ac.getBean("HeroBean"); 
     sina.getKnife().kill(); 
    } 
}

和我的jarfiles中有：彈簧3個jarfiles中+公共測井+ aopppliance

我會大大心存感激尋求幫助

堆棧跟蹤表示您從類路徑中缺少org.aspectj.weaver.reflect.ReflectionWorld。這可以在AspectJ JAR中找到，根據版本，可以是aspectjweaver.jar或aspectjtools.jar。

爲什麼我應該擁有它們？我認爲默認的aop能力來自spring 3 pack.is不正確？ – sarah

我添加了aspectjweaver.jar，現在我給這個頭添加了新的異常：線程「main」中的異常org.springframework.beans.factory.BeanCreationException：在類路徑資源[codes/aspect中定義的名稱'knifeBean'創建bean時出錯。 xml]：bean初始化失敗;嵌套異常是org.springframework.aop.framework.AopConfigException：無法代理目標類，因爲CGLIB2不可用。將CGLIB添加到類路徑或指定代理接口。 – sarah

@sarah：就這樣做 - 將cglib添加到類路徑 – skaffman

您缺少一些依賴關係。如果您正在使用maven添加這些依賴關係：

<dependency> 
     <groupId>org.aspectj</groupId> 
     <artifactId>aspectjtools</artifactId> 
     <version>1.6.2</version> 
    </dependency> 

    <dependency> 
     <groupId>cglib</groupId> 
     <artifactId>cglib</artifactId> 
     <version>2.2</version> 
    </dependency>

否則，只下載需要的jar文件，並添加到您的類路徑中。

+11

但是，如果這是Spring的必要依賴，爲什麼Spring沒有聲明它是一個依賴？ – Raedwald

我遇到了這個使用Maven的相同錯誤，並將aspectjtools依賴項解決了它。 cglib的依賴是不必要的，因爲我的項目運行良好，註釋掉了。然而，謝謝你的快速修復:) – FateNuller

如果您暴露每個pojo的接口，則不需要Cglib。
