Question

我已经将Struts 2与Spring 3集成在一起工作正常。我使用自定义ObjectFactory从Spring上下文中获取Action实例。现在我已经实现了AOP，

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

BaseAction是抽象类。我还为Service层定义了一些其他切入点。但是，当服务器启动时，我收到一个错误，

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

下面是我的strts.xml

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

请帮助!!

使用JDK代理实现AOP时，代理类必须没有args构造函数。将以下代码添加到CustomAction

public CustomAction(){}

Struts2和Spring 3集成+ AOP无法创建Action代理
