上下文webapp下的java Grizzly静态内容路径

Question

只是花了一天时间试图让Grizzly静态内容正常工作。Grizzly博客的以下URL解释了很多：Grizzly STatic Content

我试图模仿Tomcat，因为我希望静态内容的路径位于webapp或上下文句柄之下

public class SampleAdminApplication extends ResourceConfig {
    public SampleAdminApplication() {
        packages("com.companyname.sample.sampleadmin.server.services");
    }
}

public class SampleGrizzlyWebServer {
    public static void main(String[] args) throws IOException {
        try {
            HttpServer httpServer = GrizzlyHttpServerFactory.createHttpServer(
                URI.create("http://localhost:9090/Sample/"));

            /*--- Static Content ---*/
            String jarPath = getJarPath(SampleGrizzlyWebServer.class);
            CLStaticHttpHandler clStaticHttpHandler = new CLStaticHttpHandler(
                    new URLClassLoader(new URL[] {new File(jarPath).toURI().toURL()}),
                    "/", "/lib/", "/js/", "/css/");
            ServerConfiguration sc = httpServer.getServerConfiguration();
            sc.addHttpHandler(clStaticHttpHandler,"/SampleUI");

            /*--- SampleAdmin WebappContext ---*/
            WebappContext SampleAdminContext = new WebappContext("WebappContext", "/" + webapp + "/" + "SampleAdmin");

            /*--- Servlet ---*/
            final ResourceConfig sampleAdminRc = new SampleAdminApplication();
            ServletRegistration sampleAdminRegistration = SampleAdminContext.addServlet("ServletContainer", new ServletContainer(sampleAdminRc));
            sampleAdminRegistration.addMapping("/*");

            /**
             * Deploy Server
             */
            SampleAdminContext.deploy(httpServer);
            /**
             * Start Server
             */
            httpServer.start();
        } catch (Exception ex) {
            System.err.println("Error: " + ex.getMessage());
        }           
    }
} 

以上代码适用于以下URL：

http://localhost:9090/Sample/SampleAdmin/restmethod
http://localhost:9090/SampleUI/hello.htm

不过，我希望静态页面位于webapp路径“示例”下方 比如：

http://localhost:9090/Sample/UI/hello.htm

任何帮助都将不胜感激

我不知道我是否因为回答自己的问题而获得任何徽章：） 我工作了几天，试图实现过滤器的转发。这个论坛上有很多关于泽西转发的帖子没有回复。不清楚如何从过滤器中转发。忍耐

我的解决方案是使用不推荐使用的对HttpHandlerRegistration的调用。builder（）使我能够有效地设置/Sample/UI上下文

现在，代码的行为类似于Tomcat，其中Sample/{samplemin，UI}是端点

   startServer("http://", "localhost", "Sample", "UI", "9090");

   public static void startServer(String protocol, String host, String webapp, String ui, String port) {
        try {
            String BASE_URI = protocol + host + ":" + port + "/" + webapp + "/";

            HttpServer httpServer = GrizzlyHttpServerFactory.createHttpServer(URI.create(BASE_URI));

            /* - Static UI Content  -*/
            if(ui!=null && !ui.equals("")) {
                String jarPath = getJarPath(SampleGrizzlyWebServer.class);
                if (jarPath != null) {
                    CLStaticHttpHandler clStaticHttpHandler = new CLStaticHttpHandler(
                            new URLClassLoader(new URL[]{new File(jarPath).toURI().toURL()}),
                            "/", "/lib/", "/js/", "/css/");
                    ServerConfiguration sc = httpServer.getServerConfiguration();
                    sc.addHttpHandler(clStaticHttpHandler, HttpHandlerRegistration.builder().contextPath("/" + webapp + "/" + ui + "").urlPattern("").build());
                }
            }

            /* - SampleAdmin WebappContext  -*/
            WebappContext SampleAdminContext = new WebappContext("WebappContext", "/" + webapp + "/" + "SampleAdmin");

            /* - Servlet  -*/
            final ResourceConfig sampleAdminRc = new SampleAdminApplication();
            ServletRegistration sampleAdminRegistration = SampleAdminContext.addServlet("ServletContainer", new ServletContainer(sampleAdminRc));
            sampleAdminRegistration.addMapping("/*");

            /**
             * Deploy Server
             */
            SampleAdminContext.deploy(httpServer);
            httpServer.start();

            System.out.println("Jersey app started with WADL available at:");
            System.out.println(BASE_URI + "SampleAdmin/application.wdl");
            System.out.println("Hit enter to stop it...");
            System.in.read();
            httpServer.shutdown();
        }
        catch(Exception ex) {
           System.err.println("Error: " + ex.getMessage());
        }
    }
