java - 在 Eclipse IDE 上使用 Tomcat 7 时，JSP 页面未加载到本地主机上

Question

我正在从事一个使用 Java Servlets 和 JSP 的项目。早些时候项目运行良好，但现在运行项目时，服务器已正确设置，但一些 JSP 页面未运行，其他页面未显示任何应用于它的 CSS。

同时控制台显示警告。

你能检查一下你的 war/ear 文件是否存在于 tomcat 中并且也被部署了吗？如果不确定，只需在清理后重新启动服务器(删除 temp、work 和 logs 目录)。然后尝试访问http://localhost:8080/或 http://localhost:8080/YOUR_DEPLOYABLE_FILE_NAME

如果仍然无法正常工作，请检查 web.xml 中的映射。
