Question

我正在尝试将Jetty配置为http和https的代理。我已经下载了两个不同版本的码头，但我遇到了同样的问题。

我目前使用的版本是：在CentOs 6.2上运行的jetty-distribution-8.1.8.v20121106。

解压缩tar.gz后，我修改了start.ini文件，添加了etc / jetty-proxy.xml 到配置文件列表：

#etc/jetty-jmx.xml
etc/jetty.xml
<b>etc/jetty-proxy.xml</b>
etc/jetty-annotations.xml
etc/jetty-ssl.xml
# etc/jetty-requestlog.xml
etc/jetty-deploy.xml
#etc/jetty-overlay.xml
etc/jetty-webapps.xml
etc/jetty-contexts.xml
etc/jetty-testrealm.xml

Jetty定期开始。我可以访问它：

http://localhost:8080/
https://localhost:8443/

读取日志文件似乎已在端口8080,8443和8888上启动了三个抽象连接器：

2012-12-04 12:40:03.400:INFO:oejs.AbstractConnector:Started SelectChannelConnector@0.0.0.0:8080
2012-12-04 12:40:03.666:INFO:oejus.SslContextFactory:Enabled Protocols [SSLv2Hello, SSLv3, TLSv1] of [SSLv2Hello, SSLv3, TLSv1]
2012-12-04 12:40:03.668:INFO:oejs.AbstractConnector:Started SslSelectChannelConnector@0.0.0.0:8443
2012-12-04 12:40:03.668:INFO:oejs.Server:jetty-8.1.8.v20121106
2012-12-04 12:40:03.732:INFO:oejs.AbstractConnector:Started SelectChannelConnector@0.0.0.0:8888

当我将浏览器配置为访问端口8888上的代理时，jetty会失败并出现以下异常：

我已经验证文件夹$ JETTY_HOME / lib包含jar文件：

jetty-client-8.1.8.v20121106.jar

包含类org.eclipse.jetty.client.HttpExchange。要执行jetty，我使用命令： bin / jetty.sh start

命令bin / jetty.sh检查返回以下信息：

Jetty running pid=15498

谢谢

在start.ini添加客户端的OPTIONS中，代理环境要求客户端工件可用。与使用ProxyServlet相同，您需要在servlet web-inf / lib目录中拥有jetty-client及其依赖项。

无论如何，这将显示可能的选项以及在运行它时它在类路径中的作用。 start.jar真的只是帮助构建环境下的jetty运行。

java -jar start.jar --list-options

这将通过给出给定配置的示例命令行来向您显示当前的设置：

java -jar start.jar --dry-run

如需更多帮助，请查看：

java -jar start.jar --help
