GrizzlyWebServer+Spring+Jersey+从JAR中提供静态内容

Question

我正在尝试使用Grizzly的com.sun.grizzly.http.embed.GrizzlyWebServer部署基于Jersey-Spring的REST API。我还想使用相同的服务静态内容。这是我所拥有的：

String host = "localhost";
int port = 8081;
// For jersey + Spring
ServletAdapter jAdapter = new ServletAdapter("jersey");
jAdapter.setContextPath("/api");        
jAdapter.setServletInstance(new SpringServlet());
jAdapter.addContextParameter("contextConfigLocation", "classpath:spring-context.xml");
jAdapter.addServletListener("org.springframework.web.context.ContextLoaderListener");
jAdapter.addServletListener("org.springframework.web.context.request.RequestContextListener");              
// create GrizzlyWebServer
GrizzlyWebServer grizzlyServer = new GrizzlyWebServer(host, port, "webapp", false);
// add jersey adapter
grizzlyServer.addGrizzlyAdapter(jAdapter, new String[]{"/api"}); 
// start server
grizzlyServer.start();
System.out.println("Start running server(host: " + host + ",port: " + Integer.toString(port));
System.out.println("Press any key to stop the server.");
// hang on
System.in.read();
// stop
grizzlyServer.stop();

"Jersey Adapter"工作正常，但我无法获得"webapp"文件夹中的静态内容（404错误）。

我的项目文件夹结构如下：

GrizzlyTest
  -- src
  |  |
  |  -- main
  |     |
  |     -- java
  |     -- resources
  |        |
  |        -- webapp
  |        |  |
  |        |  -- index.html
  |        -- spring-context.xml
  |
  -- pom.xml

我在new GrizzlyWebServer(host, port, "webapp", false);行中提供"webapp"的路径是不是犯了错误？？

或者，还有其他方式来提供静态内容吗？？

这里有一个关于如何从Grizzly2之上的文件夹和jar文件中提供Jersey Spring资源+静态内容的示例。

https://github.com/oleksiys/samples/tree/master/jersey1-grizzly2-spring

服务器代码看起来像：

// Initialize Grizzly HttpServer
HttpServer server = new HttpServer();
NetworkListener listener = new NetworkListener("grizzly2", "localhost", 3388);
server.addListener(listener);
// Initialize and add Spring-aware Jersey resource
WebappContext ctx = new WebappContext("ctx", "/api");
final ServletRegistration reg = ctx.addServlet("spring", new SpringServlet());
reg.addMapping("/*");
ctx.addContextInitParameter("contextConfigLocation", "classpath:spring-context.xml");
ctx.addListener("org.springframework.web.context.ContextLoaderListener");
ctx.addListener("org.springframework.web.context.request.RequestContextListener");
ctx.deploy(server);
// Add the StaticHttpHandler to serve static resources from the static1 folder
server.getServerConfiguration().addHttpHandler(
        new StaticHttpHandler("src/main/resources/webapp/static1/"), "/static");
// Add the CLStaticHttpHandler to serve static resources located at
// the static2 folder from the jar file jersey1-grizzly2-spring-1.0-SNAPSHOT.jar
server.getServerConfiguration().addHttpHandler(
        new CLStaticHttpHandler(new URLClassLoader(new URL[] {
            new File("target/jersey1-grizzly2-spring-1.0-SNAPSHOT.jar").toURI().toURL()}), "webapp/static2/"),
        "/jarstatic");
try {
    server.start();
    System.out.println("In order to test the server please try the following urls:");
    System.out.println("http://localhost:3388/api to see the default TestResource.getIt() resource");
    System.out.println("http://localhost:3388/api/test to see the TestResource.test() resource");
    System.out.println("http://localhost:3388/api/test2 to see the TestResource.test2() resource");
    System.out.println("http://localhost:3388/static/ to see the index.html from the webapp/static1 folder");
    System.out.println("http://localhost:3388/jarstatic/ to see the index.html from the webapp/static2 folder served from the jar file");
    System.out.println();
    System.out.println("Press enter to stop the server...");
    System.in.read();
} finally {
    server.shutdownNow();
}
