嵌入式碼頭不能連接

嵌入式碼頭在應用程序中跟隨代碼，但不能請求成功。它永遠等待。嵌入式碼頭不能連接

public static class TestHandler extends ContextHandler { 
    public TestHandler(String contextPath) { 
     super(contextPath); 
    } 

    @Override 
    public void doHandle(String target, Request baseRequest, HttpServletRequest request, 
      HttpServletResponse response) throws IOException, ServletException { 
     super.doHandle(target, baseRequest, request, response); 
     System.out.println(""); 
    } 
} 

public static void main(String[] args) throws Exception { 

    Server server = new Server(new QueuedThreadPool(5, 4)); 
    ServerConnector connector = new ServerConnector(server); 
    connector.setPort(9001); 
    server.setConnectors(new Connector[] { connector }); 

    HandlerCollection handler = new HandlerCollection(); 
    ContextHandlerCollection contexts = new ContextHandlerCollection(); 
    contexts.setHandlers(new Handler[] { new TestHandler("/test") }); 

    handler.setHandlers(new Handler[] { contexts, new DefaultHandler() }); 
    server.setHandler(handler); 
    server.start(); 
    server.dumpStdErr(); 
    server.join(); 
}

但改變了服務器的contstructor到另一個，它會好的，有人可以解釋原因嗎？我跟蹤代碼，找不到原因。謝謝!!

public static void main(String[] args) throws Exception { 
    Server server = new Server(9001); 

    // Server server = new Server(new QueuedThreadPool(5, 4)); 
    // ServerConnector connector = new ServerConnector(server); 
    // connector.setPort(9001); 
    // server.setConnectors(new Connector[] { connector }); 

    HandlerCollection handler = new HandlerCollection(); 
    ContextHandlerCollection contexts = new ContextHandlerCollection(); 
    contexts.setHandlers(new Handler[] { new TestHandler("/test") }); 

    handler.setHandlers(new Handler[] { contexts, new DefaultHandler() }); 
    server.setHandler(handler); 
    server.start(); 
    server.dumpStdErr(); 
    server.join(); 
}

PS：帶碼頭服務器9.1.0.M0版本

你需要有至少一個線程池中的最大6：

「線程不足：最大= 5 <需要（受體= 1個+選擇= 4 + 請求= 1）」

變化的構造這樣：

Server server = new Server(new QueuedThreadPool(60, 6));

更新：

我logback.xml中（src /主/資源）

<?xml version="1.0" encoding="UTF-8"?> 
<configuration scan="false" scanPeriod="10 seconds"> 

<appender name="stdout" class="ch.qos.logback.core.ConsoleAppender"> 
    <Target>System.out</Target> 
    <encoder> 
     <pattern>%p %d{HH:mm:ss} [%c{1}] - %m%n</pattern> 
    </encoder> 
</appender> 

<logger name="org.eclipse.jetty" level="DEBUG" /> 

<root level="INFO"> 
    <appender-ref ref="stdout" /> 
</root>

堆棧跟蹤：

我瓚ge日誌級別爲DEBUG，沒有找到消息，哪個java文件用這個消息存在？謝謝 – nealons 2014-11-05 10:09:07

我使用Slf4J + Logback作爲日誌框架。我認爲你的應用程序的一些消息沒有被記錄，請參閱[這裏]（http://www.eclipse.org/jetty/documentation/current/configuring-logging.html#selecting-log-framework）。 – Stefan 2014-11-05 10:15:16

我也用slf4j + logback – nealons 2014-11-05 10:16:42
