1.spring得到servletContext，这个和session没有什么关系，上下文可以说是一个session容器，一个上下文可以有多个会话session

在web.xml中有以下配置后。加入spring对上下文的监听，

    <listener>

       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

    </listener>

在后台用一下代码就可以得到javax.servlet.ServletContext

ContextLoader.getCurrentWebApplicationContext().getServletContext()

2.cxf得到session的方法，这个仅仅是为了测试每次webservice请求session不一样

package com.gaeainfo.tclgb.ws;import javax.annotation.Resource;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpSession;import javax.servlet.http.HttpSessionContext;import javax.xml.ws.WebServiceContext;import javax.xml.ws.handler.MessageContext;import org.apache.cxf.transport.http.AbstractHTTPDestination;import org.dom4j.Document;import org.dom4j.DocumentHelper;import org.dom4j.Element;import org.springframework.stereotype.Component;import org.springframework.web.context.ContextLoader;@Component(value="loginManagerWs")public class UserManagerWebServiceImpl implements UserManagerWebService {//会自动注入，配置了cxf监听之后    @Resource      private WebServiceContext context;     @Override    public String showUserInfo() {        /*String userName = (String) session.getAttribute("userName");        String depName = (String) session.getAttribute("depName");                Document doc = DocumentHelper.createDocument();        Element elt = doc.addElement("root").addElement("userName").addText(userName).addElement("depName").addText(depName);        String result = doc.asXML();*/        MessageContext ctx = context.getMessageContext();           HttpServletRequest request = (HttpServletRequest)            ctx.get(AbstractHTTPDestination.HTTP_REQUEST);           System.out.println(request.getSession().getId());                return "";    }}
