带有Jersey和嵌入式Jetty的CrossOriginFilter

我知道这个问题和上但他们没有回答和4年前问。此外，没有答案对我有用。我无法将crossOriginFilter添加到嵌入式码头服务器。

我的代码-不幸的是，我没有在响应中得到任何Header字段！

        ServletContextHandler dynamicResourceContext = new ServletContextHandler();
        dynamicResourceContext.setContextPath("/rest");

        FilterHolder holder = new FilterHolder(CrossOriginFilter.class);
        holder.setInitParameter(CrossOriginFilter.ALLOWED_ORIGINS_PARAM, "*");
        holder.setInitParameter(CrossOriginFilter.ACCESS_CONTROL_ALLOW_ORIGIN_HEADER, "*");
        holder.setInitParameter(CrossOriginFilter.ALLOWED_METHODS_PARAM, "GET,POST,HEAD");
        holder.setInitParameter(CrossOriginFilter.ALLOWED_HEADERS_PARAM, "X-Requested-With,Content-Type,Accept,Origin");
        dynamicResourceContext.addFilter(holder, "/*", EnumSet.of(DispatcherType.REQUEST));

        ServletContextHandler staticResourceContext = new ServletContextHandler();
        staticResourceContext.setContextPath("/resources");
        DefaultServlet defaultServlet = new DefaultServlet();
        ServletHolder holderPwd = new ServletHolder("default", defaultServlet);
        holderPwd.setInitParameter("resourceBase", "./src/webapp/");


        staticResourceContext.addServlet(holderPwd, "/*");

        HandlerList handlers = new HandlerList();
        handlers.addHandler(dynamicResourceContext);
        handlers.addHandler(staticResourceContext);

        server = new Server(port);
        server.setHandler(handlers);
        // set logging to console
        StdErrLog logger = new StdErrLog();
        logger.setDebugEnabled(webserverLogging);
        Log.setLog(logger);

        ServletHolder jerseyServlet = dynamicResourceContext
                .addServlet(org.glassfish.jersey.servlet.ServletContainer.class, "/*");

        jerseyServlet.setInitOrder(0);


        // Tells the Jersey Servlet which REST service/class to load.
        jerseyServlet.setInitParameter("jersey.config.server.provider.classnames", getMyClasses());


        try {
            server.start();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            // server.destroy();
        }    

我怎么了 我没有收到任何错误消息！

编辑

另外，以下教程无法正常工作。无论是使用Postman还是使用chrome，我都看不到其他响应头条目。响应如下所示：

HTTP/1.1 200 OK
Date: Tue, 26 Mar 2019 19:41:36 GMT
Content-Length: 0
Server: Jetty(9.4.15.v20190215)

编辑我能够使用资源配置创建标头字段，但是我仍然无法使用CrossOriginFilter创建标头字段。

ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);

context.setContextPath("/"); 
Server jettyServer = new Server(9998);

jettyServer.setHandler(context);


ResourceConfig webapiResourceConfig = new ResourceConfig();
webapiResourceConfig.register(CorsFilter.class);


ServletHolder jerseyServlet  = new ServletHolder(new ServletContainer(webapiResourceConfig));
context.addServlet(jerseyServlet, "/*");
        //context.addServlet(org.glassfish.jersey.servlet.ServletContainer.class, "/*");

jerseyServlet.setInitOrder(0);

jerseyServlet.setInitParameter( "jersey.config.server.provider.classnames",MyServerConfig.class.getCanonicalName());
