java - Grizzly 嵌入式服务器 + Jersey 服务 + Servlet 过滤器

Question

以下代码运行我的 REST 服务，但我的 servlet 过滤器永远不会被调用。有任何想法吗？

WebappContext webappContext = new WebappContext("grizzly web context", "");

FilterRegistration testFilterReg = webappContext.addFilter("TestFilter", TestFilter.class);
testFilterReg.addMappingForUrlPatterns(EnumSet.allOf(DispatcherType.class), "/*");

ResourceConfig rc = new ResourceConfig().register(MyResource.class);
HttpServer httpServer = GrizzlyHttpServerFactory.createHttpServer(URI.create("http://localhost:8080/myapp/"), rc);
webappContext.deploy(httpServer);

简而言之，以上述方式注册 ResourceConfig 将有效地绕过 Grizzly Servlet 容器。

为了利用 Servlet 过滤器，您需要这样做：

    WebappContext webappContext = new WebappContext("grizzly web context", "");

    FilterRegistration testFilterReg = webappContext.addFilter("TestFilter", TestFilter.class);
    testFilterReg.addMappingForUrlPatterns(EnumSet.allOf(DispatcherType.class), "/*");

    ServletRegistration servletRegistration = webappContext.addServlet("Jersey", org.glassfish.jersey.servlet.ServletContainer.class);
    servletRegistration.addMapping("/myapp/*");
    servletRegistration.setInitParameter("jersey.config.server.provider.packages", "com.example");


    HttpServer server = HttpServer.createSimpleServer();
    webappContext.deploy(server);
    server.start();
