我有一个嵌入 Jetty 作为 Web 服务器来托管 RESTful API 的应用程序。我一直在 Ubuntu 上的 Eclipse 中开发它，从 IDE 启动时一切正常。但是，当我打包应用程序并将其部署在服务器上时，Jetty 不再响应请求。

服务器确实在我指定的端口上打开了一个套接字，并为 spring-mvc 打开 INFO 日志记录显示我的控制器及其方法被适当地映射。请求成功打开连接，但没有数据被发回，事实上该请求从未发送到我的控制器代码。当我关闭应用程序时，我看到所有已建立的连接都被终止了。

我已经检查了 Eclipse 项目的类路径上的所有库在部署时都在类路径上。我还应该检查什么来弄清楚为什么它在 Eclipse 中工作并且在其他地方被破坏了？

Jetty 版本 9，Java 版本 1.7，Spring 3.2.2。

当我提出请求时，编辑来自 Jetty 的调试日志记录：

我需要调度程序 servlet 来了解定义此 Jetty 服务器的 ApplicationContext，因此作为参考，我的 DispatcherServletWrapper 类如下所示：

package com.company.project.api;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.GenericWebApplicationContext;
import org.springframework.web.servlet.DispatcherServlet;

public class DispatcherServletWrapper extends DispatcherServlet implements ApplicationContextAware {

    private static final long serialVersionUID = -2281511575328213502L;
    private ApplicationContext appContext;

    @Override
    public void setApplicationContext(ApplicationContext arg0)
            throws BeansException {
        this.appContext = arg0; 
    }

    protected WebApplicationContext createWebApplicationContext(WebApplicationContext arg0) {
        GenericWebApplicationContext wac = new GenericWebApplicationContext();
        wac.setParent(appContext);
        wac.refresh();

        return wac;
    }

}

啊，Jetty 9 改变了连接器。

从 Jetty 9 开始，连接器由 ConnectionFactory 链组成，提供连接类型检测和回退。

这样做是为了支持替代 Web 连接类型的现代现实（例如 TLS 扩展、NPN、SPDY、WebSocket 甚至为HTTP/2.0.

以下是一些嵌入式示例：

在 Jetty 9 中配置标准 HTTP 连接器

package org.eclipse.jetty.embedded;

import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.server.ServerConnector;

public class OneConnector
{
    public static void main(String[] args) throws Exception
    {
        // The Server
        Server server = new Server();

        // HTTP connector
        ServerConnector http = new ServerConnector(server);
        http.setHost("localhost");
        http.setPort(8080);
        http.setIdleTimeout(30000);

        // Set the connector
        server.addConnector(http);

        // Set a handler
        server.setHandler(new HelloHandler());

        // Start the server
        server.start();
        server.join();
    }
}

在 Jetty 9 中为 SSL + NPN + SPDY/3 + SPDY/2 + HTTPS 配置连接器链

package org.eclipse.jetty.embedded;

import org.eclipse.jetty.server.HttpConfiguration;
import org.eclipse.jetty.server.HttpConnectionFactory;
import org.eclipse.jetty.server.SecureRequestCustomizer;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.server.ServerConnector;
import org.eclipse.jetty.server.SslConnectionFactory;
import org.eclipse.jetty.spdy.server.NPNServerConnectionFactory;
import org.eclipse.jetty.spdy.server.SPDYServerConnectionFactory;
import org.eclipse.jetty.spdy.server.http.HTTPSPDYServerConnectionFactory;
import org.eclipse.jetty.spdy.server.http.ReferrerPushStrategy;
import org.eclipse.jetty.util.ssl.SslContextFactory;

public class SpdyConnector
{
    public static void main(String[] args) throws Exception
    {
        String jetty_home = System.getProperty("jetty.home","../../jetty-distribution/target/distribution");
        System.setProperty("jetty.home", jetty_home);

        // The Server
        Server server = new Server();

        // HTTP Configuration
        HttpConfiguration http_config = new HttpConfiguration();
        http_config.setSecureScheme("https");
        http_config.setSecurePort(8443);

        // HTTP connector
        ServerConnector http = new ServerConnector(server,new HttpConnectionFactory(http_config));        
        http.setPort(8080);
        server.addConnector(http);

        // SSL Context Factory for HTTPS and SPDY
        SslContextFactory sslContextFactory = new SslContextFactory();
        sslContextFactory.setKeyStorePath(jetty_home + "/etc/keystore");
        sslContextFactory.setKeyStorePassword("OBF:1vny1zlo1x8e1vnw1vn61x8g1zlu1vn4");
        sslContextFactory.setKeyManagerPassword("OBF:1u2u1wml1z7s1z7a1wnl1u2g");

        // HTTPS Configuration
        HttpConfiguration https_config = new HttpConfiguration(http_config);
        https_config.addCustomizer(new SecureRequestCustomizer());

        // SPDY versions
        HTTPSPDYServerConnectionFactory spdy2 = 
            new HTTPSPDYServerConnectionFactory(2,https_config);

        HTTPSPDYServerConnectionFactory spdy3 = 
            new HTTPSPDYServerConnectionFactory(3,https_config,new ReferrerPushStrategy());

        // NPN Factory
        SPDYServerConnectionFactory.checkNPNAvailable();
        NPNServerConnectionFactory npn = 
            new NPNServerConnectionFactory(spdy3.getProtocol(),spdy2.getProtocol(),http.getDefaultProtocol());
        npn.setDefaultProtocol(http.getDefaultProtocol());

        // SSL Factory
        SslConnectionFactory ssl = new SslConnectionFactory(sslContextFactory,npn.getProtocol());

        // SPDY Connector
        ServerConnector spdyConnector = 
            new ServerConnector(server,ssl,npn,spdy3,spdy2,new HttpConnectionFactory(https_config));
        spdyConnector.setPort(8443);
        server.addConnector(spdyConnector);

        // Set a handler
        server.setHandler(new HelloHandler());

        // Start the server
        server.start();
        server.join();
    }
}
