我的 Tomcat 有问题，它停止工作了。我在 3 周前安装了 Tomcat，我已经制作了 50 多个 web 动态项目、maven 项目，一切都运行良好。今天 Tomcat 停止工作了。例如，我在 Eclipse 中创建了一个项目，当我尝试运行它时出现此错误:本地主机上的服务器 Tomcat v9.0 服务器无法启动。

我可以从 Windows 服务启动 Tomcat，我可以打开 http://localhost:8080/浏览器中的页面，但我无法在 eclipse 中启动 Tomcat。不只是针对一个项目，因为所有项目都不起作用。问题出在 Tomcat 上，而不是所有应用程序上。我卸载并重新安装它，但不起作用。我应该怎么办？我们将不胜感激任何反馈!

我在控制台中收到此消息:

INFO: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

最佳答案

来自上面的评论

“严重:子容器在启动期间失败”

“引起:java.lang.IllegalArgumentException:名为 [LoginRegisterServlet] 和 [login.register.LoginRegisterServlet] 的 servlet 都映射到不允许的 url-pattern [/loginRegister]”

您的“/loginRegister”代码之前是否有效？

“我知道只有一个名为LoginRegisterServlet的servlet，我刚刚删除了它，现在我看到Tomcat启动成功了。感谢您的回复!您帮了我很多。”

关于jsp - 本地主机上的 Tomcat v9.0 服务器无法在 Eclipse 中启动，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/51025776/
