我想在Windows下用netbeans生成的.war文件来部署它，我的项目是一个web应用程序，我想在LINUX（LUBUNTU）中运行，但是我无法启动它。我正在使用 manager-gui。

【解决方案1】：

这是您过分冗长（且重复）的日志中最重要的一行：

严重：错误 listenerStart

这基本上意味着ServletContextListener 实现由类上的@WebListener 注释或web.xml 中的<listener> 条目注册，在contextInitialized() 方法中引发了未处理的异常。这通常是由开发人员的错误（错误）引起的，需要修复。例如，NullPointerException。

如果您无法通过仅盯着或单元测试 contextInitialized() 方法中的代码来找出原因，那么您需要在项目的 src 文件夹中创建一个 logging.properties 文件（在那里您有你的 Java 类；它至少应该最终在构建的 WAR 的 /WEB-INF/classes 文件夹中结束），内容如下：

org.apache.catalina.core.ContainerBase.[Catalina].level = 信息 org.apache.catalina.core.ContainerBase.[Catalina].handlers = java.util.logging.ConsoleHandler

这将告诉 Tomcat 在启动侦听器（和过滤器）期间将异常记录到控制台。

【讨论】：

  • 在哪里可以查看logging.properties的日志结果？
  • 控制台。与您从问题中复制粘贴该部分的日志相同。
