我有一个非常简单的 Java REST 应用程序，它使用 grizzly2 (jersey-grizzly2 1.12) 和 jersey (jersey-bundle 1.12)

当我发出第一个 http 请求时，我得到一个 404 响应（但映射的方法仍然在服务器上执行）。如果我再次发出相同的请求，那么我会得到预期的 200 响应。

疯狂的部分是，即使是 404 错误，映射的方法仍然执行。

也许有一个错误？还是我错误地配置了我的服务器？这是我第一次尝试 grizzly2，所以欢迎任何见解！

我这样启动服务器：

final ResourceConfig rc = new DefaultResourceConfig(
            TestResource.class
            );
rc.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, true);
rc.getFeatures().put(ResourceConfig.FEATURE_TRACE, true);

URI path = UriBuilder.fromPath(baseUri).build();                        
HttpServer httpServer = GrizzlyServerFactory.createHttpServer(path, rc);            
httpServer.start();

我的资源如下所示：

@Path("/test")
public class TestResource {
    @GET    
    @Produces(MediaType.APPLICATION_JSON)
    @Path("go") 
    public Integer startSomethingElse() {
        return new Integer(4);
    }        
}

还有我的示例连接示例：

然后第二次尝试（完全相同的请求，紧随第一次之后）
