jetty服务器无响应,嵌入式Jetty Web服务器无法正常工作，处理程序未被调用

我正在尝试将Jetty 8(8.1.18.v20150929)嵌入到Java(jdk1.7.0_67)应用程序中。我有以下代码：

public static final String HTTP_PATH = "/session";

public static final int HTTP_PORT = 9995;

// Open the HTTP server for listening to requests.

logger.info("Starting HTTP server, Port: " + HTTP_PORT + ", Path: "

+ "/session");

httpServer = new Server();

SelectChannelConnector connector = new SelectChannelConnector();

connector.setPort(HTTP_PORT);

connector.setHost("localhost");

httpServer.addConnector(connector);

TestHttpHandler handler = new TestHttpHandler(this);

ContextHandler ch = new ContextHandler();

ch.setContextPath(HTTP_PATH);

ch.setHandler(handler);

httpServer.setHandler(ch);

try {

httpServer.start();

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

我的处理程序非常基本作为测试：

public void handle(String target, Request baseRequest,

HttpServletRequest request, HttpServletResponse response)

throws IOException, ServletException {

logger.debug("Handling");

}

如果我运行应用程序然后使用CURL向http://localhost:9995/session发送GET请求，则它返回200状态，但没有调试输出。

我在线阅读了很多例子但由于某些原因我似乎无法使处理程序正常工作。难道我做错了什么？感谢
