struts2註釋spring管理bean

Question

我使用Spring來管理struts 2動作bean。我正在嘗試從基於XML的配置遷移到基於註釋的配置。我正在使用struts2-spring-plugin，以便struts獲取由spring管理的對象的句柄。 以下內容位於myAction的applicationContext文件中。

<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:context="http://www.springframework.org/schema/context" 
    xsi:schemaLocation=" 
     http://www.springframework.org/schema/beans http://www.springframework.org/schema 
     /beans/spring-beans-3.0.xsd 
     http://www.springframework.org/schema/context http://www.springframework.org 
     /schema/context/spring-context-3.0.xsd"> 
    <context:annotation-config /> 
    <bean id="myAction123" class="com.action.MyAction" scope="prototype"></bean> 
</beans> 

在struts2-tiles配置文件中，我定義了請求映射。該映射使用對spring創建的bean的引用。 class屬性引用spring bean定義中定義的id屬性。

<action name="myAction_*" method="{1}" class="myAction123"> 
     <result name="success" type="tiles">action.request.view</result> 
    </action> 

Action類被註釋如下：

@Controller 
public class MyAction { 

    @Autowired 
    public MyService myService; 

    public MyService getMyService() { 
     return myService; 
    } 

    public void setMyService(MyService myService) { 
     this.myService = myService; 
    } 

    public String doSearch() { 
     /* ... */ 
    } 
} 

請看以下堆棧跟蹤，通過支柱拋出，當我刪除春風行動bean引用。

據我所知，我沒有把正確的註解放在哪個地方，這是造成這個問題的原因。儘管我已經嘗試瞭解這一點，但我仍然對移植這個特定部分感到困惑。我無法弄清楚我是否會爲此使用struts 2註釋或者Spring註解。任何幫助表示讚賞。謝謝。

您還需要行

<context:component-scan base-package="my.package.path" /> 

在您的應用程序context.xml文件來告訴Spring去哪裏去找註釋。使用@Controller註釋沒有任何問題。
