如何通过CXF拦截器使会话无效？ [英] How to invalidate session by CXF Interceptor?

问题描述

我是Cxf Web服务的新手，但所提供的信息不知所措。我写了一个cxf Interceptor（cxf：outInterceptors），它扩展了AbstractPhaseInterceptor。服务执行后，我试图使当前会话无效。我的问题是：

I am new to Cxf webservice and bit overwhelmed by information provided. I have written a cxf Interceptor(cxf:outInterceptors) which extends AbstractPhaseInterceptor. I am trying to invalidate the current session after service executes. My issues are:

1. 我是否在构造函数中使用了正确的相位？ （阶段发送）


2. 如何从消息中获取会话信息？现在，对于下面的方法，请求实例返回null。

还是有更好的方法呢？

  public ServiceSessionInvalidator() {
      super(Phase.SEND);
  }

@Override
public void handleMessage(Message message) throws Fault {

    System.out.println("Hitting Handler");

    HttpSession session;

    HttpServletRequest req = (HttpServletRequest)message.get(AbstractHTTPDestination.HTTP_REQUEST);

    session = (req != null)? req.getSession(): null;

    if(req == null ){

        System.out.println("Request is Null");

    }


}

输出：

16 Jun 2015 13:35:40 INFO   - Inbound Message
----------------------------

ID: 1

Address: http://localhost:8090/services/VariableService/variableService/

Http-Method: GET

推荐答案

@Resource
WebServiceContext wsContext;
@Context
private HttpServletRequest request;



 private HttpServletRequest invalidateSession() {
    MessageContext mc = wsContext.getMessageContext();
    HttpServletRequest req;
    if (mc != null) {
        req = (HttpServletRequest) mc.get(MessageContext.SERVLET_REQUEST);
    } else {
        req = request;
    }

    req.getSession().invalidate();
}
