Question

嗨我想从休息服务中的http会话对象访问anf的数据我已经google了很多，发现javax.ws.rs.core.Context的@context给出了HttpServlet对象但是因为它是interfaec我总是得到它空值。我的代码如下

@Context
private HttpServletRequest request;
private HttpSession session = request.getSession(); 

@Path(value = "/listAllQuestion")
@GET
@Produces(MediaType.APPLICATION_JSON)
public Response listAllQuestion(){
    int pgNo = 1;
    int pgSize = 5;
    IPResponse response = new IPResponse();
    try {
        if (session.getAttribute(IpConstants.TOPIC) != null
                && session.getAttribute(IpConstants.LEVEL) != null) {
                    session.removeAttribute(IpConstants.TOPIC);
                    session.removeAttribute(IpConstants.LEVEL); 
        }                                              
        session.setAttribute(IpConstants.PAGENO, pgNo);
        session.setAttribute(IpConstants.PAGESIZE, pgSize);
        quesList = questionService.listAllQuestion(pgNo, pgSize);

请试试这个：

将您的request.getSession（）向下移动到listAllQuestion（）方法中，如下所示：

public Response listAllQuestion(){
    HttpSession session = request.getSession():

我不相信您的请求对象将填充在实际请求处理程序的上下文之外。
