之前我的 tomcat 服务器运行良好。

但突然出现以下错误。

请帮忙解决这个问题

谢谢

最佳答案

我想错误日志说明了一切。您在 tomcat 上部署了多个 servlet,它们的 web.xml 中映射了相同的 URL 模式 [/*]名为 [Project-1] 和 [com.example.project_1.Project_1UI$Servlet] 的 servlet 都映射到 url-pattern [/*],这在 org.apache.catalina.deploy.WebXml 中是不允许的。添加ServletMapping

这是令人困惑的,因为每当您点击 URL localhost:[yourPort]/[AppName-Maybe]/ 时,容器将不知道要调用哪个 servlet。尝试浏览 web.xml 并修复此问题,或者您可以在此处发布相同的内容并获得更多帮助。
