泽西灰熊容器瓦特/ @WebListener ServletContextListeners

Question

我有我的JAX-RS网络服务与灰熊服务器运行，但我不能配置我的@WebListener工作。我正在构建一个框架，因此我无法切换到灰熊听众。

我有最新的图书馆。

<dependency> 
    <groupId>javax.servlet</groupId> 
    <artifactId>javax.servlet-api</artifactId> 
    <version>3.0.1</version>

</dependency> 
<dependency> 
    <groupId>org.glassfish.jersey.containers</groupId> 
    <artifactId>jersey-container-servlet</artifactId> 
</dependency> 

下面是一些代码：

@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; 
    } 

的调用context.deploy（HttpServer的）抛出IllegalStateException异常。

Answer 1

IllegalStateException异常：资源配置是不是在这种情况下修改

它，除非布尔标志传递给重载的方法，因为createHttpServer(uri, resourceConfig)自动启动服务器，告诉它不到自动启动。

另一件事是你正在试图创建两个应用程序。一旦您拨打createHttpServer通过ResourceConfig，而另一次当您创建ServletContainer与ResourceConfig相同。

你应该做的只是超载createHttpServer(uri)。这不会创建应用程序，并且不会启动服务器。当您创建ServletContainer与ResourceConfig并将其传递到WebAppContext时，您创建泽西岛应用程序。

Answer 2

感谢，过滤器和监听器工作

/** 
* 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)); 

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)); 
registration.addMapping("/*"); 

context.deploy(httpServer); 
return httpServer; 
}
