Question

我已经使用grizzly-server运行了JAX-RS Web服务，但我无法配置我的@WebListener。我正在构建一个框架，所以我无法切换到Grizzly听众。

我有最新的图书馆。

    <artifactId>jersey-container-servlet</artifactId>
</dependency>

以下是一些代码：

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

    @WebListener
    public class SampleAdminListener implements ServletContextListener {
        private static final Logger log = Logger.getLogger(SampleAdminListener.class);

        @Override
        public void contextInitialized(ServletContextEvent servletContextEvent) {
            log.info("SampleAdminListener Initializing context.");
        }

        @Override
        public void contextDestroyed(ServletContextEvent servletContextEvent) {
            log.info("SampleAdminListener Destroying context.");
        }
    }
    /**
     * Starts Grizzly HTTP server exposing JAX-RS resources defined in this application.
     * @return Grizzly HTTP server.
     */
    public static HttpServer startServer() {
        // create a resource config that scans for JAX-RS resources and providers
        // in com.example.rest package
        final ResourceConfig rc = new SampleAdminApplication();

        // create and start a new instance of grizzly http server
        // exposing the Jersey application at BASE_URI
        HttpServer httpServer = GrizzlyHttpServerFactory.createHttpServer(URI.create(BASE_URI), rc);

        WebappContext context = new WebappContext("WebappContext", "/" + webapp);
        context.addListener("com.vilabs.sample.sampleadmin.server.servlet.SampleAdminListener");
        context.addFilter("SampleAdminFilter", SampleAdminFilter.class);
        context.addFilter("SampleAdminCsrfFilter", SampleAdminCsrfFilter.class);
//        ServletRegistration registration = context.addServlet("ServletContainer", new ServletContainer(rc));
        ServletRegistration registration = context.addServlet("ServletContainer", new ServletContainer(rc));
        registration.addMapping("/*");

        context.deploy(httpServer);
        return httpServer;
    }

对context.deploy（httpServer）的调用会抛出IllegalStateException。

谢谢，过滤器和监听器正在运行

logout:
            path: /logout
            handlers: [logout_handler]

Answer 2

IllegalStateException：资源配置在此上下文中不可修改

这是因为select department,count(*), sum(case when datecolumn= GETDATE() then 1 else 0 end) as Today, sum(case when month(datecolumn) =month(GETDATE() and year(datecolumn) =year(GETDATE()) then 1 else 0 end) as ThisMonth from YourTable group by department会自动启动服务器，除非布尔标志传递给重载方法，告诉它不自动启动。

另一件事是你正在尝试创建两个应用程序。一旦您致电createHttpServer(uri, resourceConfig)传递createHttpServer，另一次使用ResourceConfig创建ServletContainer。

你应该做的只是重载的ResourceConfig。这不会创建一个应用程序，也不会启动服务器。并在使用createHttpServer(uri)创建ServletContainer时创建Jersey应用程序，并将其传递给ResourceConfig。
