定制SessionListener，名称没有在此背景下，javax.naming.NameNotFoundException绑定 [英] Custom SessionListener, name is not bound in this context, javax.naming.NameNotFoundException

问题描述

我想实现HttpSessionListener使这一监听器的用户可以注册实施ISessionEvent接口的会话活动code是如下：

I am trying to implement HttpSessionListener so that users of this listener can register implementation of ISessionEvent interface to session Events.code is below:

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());
 }
}

当用户执行ISessionEvent并添加一个bean，实现SessionCreated和SessionDestroyed功能将被当这些事件发生调用。你可以问你为什么不只是写里面的侦听器的方法，我不我只是想。

When user implement ISessionEvent and add as a bean, SessionCreated and SessionDestroyed functions of implementation will be called when these events occured. You can ask why dont you just write inside listeners methods, i dont i'm just trying.

当我尝试code上面我得到了以下错误消息：

When i try the code above i got the following error message:

Resource注解导致错误，但我不能解决这个问题。

Resource annotation causes the error but i could not resolve it.

感谢所有...

接口和实现

@Resource
public interface ISessionEvent {

公共无效SessionCreated（HttpSession的会议）;
 公共无效SessionDestroyed（HttpSession的会议）;

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：使用的链接工作。

推荐答案

这是仅仅因为 ISessionEvent 不管理，我相信。是否有 @Resource 标注？喜欢的东西，

It's merely because ISessionEvent is not managed, I believe. Does it have @Resource annotation? Something like,

@Resource
public class ISessionEvent {...}
