Struts2和Spring 3集成+ AOP未能創建Action代理

Question

我已經集成了Struts 2和Spring 3，它工作正常。我使用自定義的ObjectFactory從Spring上下文獲取Action實例。現在我已經實現了AOP like，

@Pointcut("target(com.motherframework.frontendplugin.struts2.action.BaseAction)") 

BaseAction是抽象類。我還有一些爲Service層定義的切入點。但是，當服務器啓動時，我得到一個錯誤一樣，

DEBUG JdkDynamicAopProxy:113 - Creating JDK dynamic proxy: target source is SingletonTargetSource for target object [com.motherframework.application.school.action.security.CustomAction@c11557] 
DEBUG DefaultListableBeanFactory:452 - Finished creating instance of bean 'customAction'

SEVERE: Exception starting filter struts2 
Unable to load configuration. - action - file:<file-path>/EPMS/WEB-INF/classes/struts-security.xml:6:80 

... 
Caused by: Action class [customAction] does not have a public no-arg constructor 

下面是我strts.xml

<action name="restrictUser" class="customAction" method="restrictUser" /> 

請幫助！

當您使用JDK代理實現AOP時，代理類必須沒有參數構造函數。 下面的代碼添加到CustomAction

public CustomAction(){}
