java - 在 Tomcat 服务器中部署 WAR 文件时出错 - org.springframework.web.context.ContextLoaderListener 未加载

Question

我的项目在通过 eclipse 和 tomcat 服务器 7 运行的本地计算机上运行良好。我正在通过执行 Maven install 生成 WAR 文件并将其部署到 tomcat 服务器中。部署后项目未运行并显示 404 Not Found。

在日志文件中我得到这样的错误:

有人可以帮我解决问题吗？我找不到我做错的地方。我在 pom.xml

中设置了所有依赖项

刚刚注意到该项目在 eclipse 中运行良好，但在独立服务器中运行良好。复制您在 eclipse tomcat 配置中设置的所有运行时属性，并将其粘贴到独立的 tomcat catalaina 文件中。您可以找到 java opts 并添加它。

存在空指针异常。

您可以在 PropertyUtil 类的第 86 行放置一个调试点。从方法名getPropertiesFromEnvironmentVariable来看，我猜测是某个环境变量没有设置，或者获取它的值有问题。

如果无法调试，则尝试使用 System.out.println 语句查看什么是 null。

我希望你能从这里调试。
