Grizzly Embedded Server + 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。有什么想法吗？

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，以您上面的方式注册ResourceConfig将有效地绕过Grizzly Servlet容器。

为了利用Servlet过滤器，您需要这样的东西：

    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();
