我在嵌入式模式下使用 Jetty 6。我在 ContextHandlerCollection 中有许多 servlet。除了这个问题之外,servlet 在它们不同的 URL 上也能正常工作。

ContextHandlerCollection contexts = new ContextHandlerCollection();
server.setHandler(contexts);
HandlerContainer mainhandler = contexts;

    Context qxrpc = new Context(contexts,"/api",Context.SESSIONS);

    ServletHolder rpcServHolder = new ServletHolder(new FrzRpcServlet()); 
    rpcServHolder.setInitParameter("referrerCheck", "public"); 
            // allows cross-domain calls
    qxrpc.addServlet( rpcServHolder, "*.qxrpc");

    Context statscontext =new Context(contexts,"/stats",Context.SESSIONS);
    ServletHolder statsHolder = new ServletHolder(new FrzStatsServlet());
    statsHolder.setInitParameter("restrictToLocalhost", "false"); 
                // allows cross-domain calls        
    statscontext.addServlet(statsHolder, "/*");

    Context hellocontext = new Context(contexts,"/hello", Context.SESSIONS);        
    hellocontext.addServlet(new ServletHolder(new HelloServlet("HELLO TEST: ")),
                                          "/*");

    Context zdbcontext = new Context(contexts,"/zdb", Context.ALL);     
    ServletHolder zdbHolder = new ServletHolder(new FrzZdbServlet());
    statsHolder.setInitParameter("restrictToLocalhost", "false");
            // allows cross-domain calls        

    zdbcontext.addServlet(zdbHolder, "/*");

    Context root = new Context(mainhandler,"/",Context.SESSIONS);
    root.setResourceBase(docroot);
    root.addServlet(DefaultServlet.class, "/");  

我知道 POST 请求正在发送到我的服务器。这是一些 ngrep 输出:

不成功的 POST - 报告 200 OK - 但从未到达 servlet

我无法弄清楚为什么 doPost() 没有被调用,而 doGet() 被调用。有问题的 servlet 是 FrzZdbServlet。

在 Google 上找到了许多线程,但 Jetty 的人只指向示例,而这些示例又只为 Context 示例实现 do doGet()。就像在这里

另外,我从 GWT 代码发布,我使用的是内容类型的应用程序/json。这可能是问题吗?任何指针将不胜感激。

我的上下文显然不接受内容类型为:application/json 的 POST。在我的客户端代码上删除它修复了它。如果其他人有意见,不胜感激。
