java - Jetty 无法启动 - ContextHandler 已停止

Question

我试图找出根本原因，而我的应用程序在 Jelastic 上运行时无法工作，而在本地使用 maven jetty:run 运行时则工作正常。

Jetty 服务器上的这个应用程序无法启动的主要原因是什么？有什么提示吗？

Answer 1

一些建议(来自输出):

WARN:oejs.HomeBaseWarning:main: This instance of Jetty is not running from a separate {jetty.base} directory, this is not recommended. See documentation at http://www.eclipse.org/jetty/documentation/current/startup.html

按照这些说明进行操作，设置正确的 ${jetty.base} 目录，不要更改、添加、删除、重命名或一般更改 ${jetty.home} 中的任何内容 目录(又名 jetty-distribution 目录。系统上的 /opt/repo/versions/9.3.7/)

首先，在磁盘上的某个位置解压缩(或解压)jetty-distribution 的新副本。然后按照说明创建 ${jetty.base} 目录(这是您的特定 Jetty 实例的配置，包括 webapps)
