java - 自定义SessionListener，名称未在此上下文中绑定(bind)javax.naming.NameNotFoundException

我正在尝试实现HttpSessionListener，以便该侦听器的用户可以将ISessionEvent接口的实现注册到会话Events.code如下：

public class MySessionListener implements HttpSessionListener{

 @Resource
 ISessionEvent sessionEvent;

 public ISessionEvent getSessionEvent() {
  return sessionEvent;
 }

 public void setSessionEvent(ISessionEvent sessionEvent) {
  this.sessionEvent = sessionEvent;
 }

 @Override
 public void sessionCreated(HttpSessionEvent arg0) {
  sessionEvent.SessionCreated(arg0.getSession());
 }

 @Override
 public void sessionDestroyed(HttpSessionEvent arg0) {
  sessionEvent.SessionDestroyed(arg0.getSession());
 }
}

当用户实现ISessionEvent并作为bean添加时，这些事件发生时将调用实现的SessionCreated和SessionDestroyed函数。您可以问为什么不只在侦听器方法中编写代码，我不尝试。

当我尝试上面的代码时，出现以下错误消息：

资源注释导致错误，但我无法解决。

谢谢大家...

接口与实现

@Resource
public interface ISessionEvent {

public void SessionCreated(HttpSession session);
 public void SessionDestroyed(HttpSession session);


}

@Resource
public class SessionEvent implements ISessionEvent {

 @Override
 public void SessionDestroyed(HttpSession session) {
  System.out.println("From Session Event Callback(Destroy):" + session.getId());
 }

 @Override
 public void SessionCreated(HttpSession session) {
  System.out.println("From Session Event Callback(Create):" + session.getId());
 }

}

Bean定义

<context:annotation-config/>
<context:component-scan base-package="com.mehmet6parmak">
</context:component-scan>

<bean id="sessionEvent" autowire="byName" class="com.mehmet6parmak.sessionlistener.SessionEvent"></bean>

解决方案：使用link中使用的方法。

最佳答案

我相信，这仅仅是因为ISessionEvent没有得到管理。是否具有@Resource批注？就像是，

@Resource
public class ISessionEvent {...}
