【问题标题】：Tomcat v8.0 Server Failed to StartTomcat v8.0 服务器启动失败
【发布时间】：2019-06-08 14:54:54
【问题描述】：

我正在尝试为我的最终 uni 项目制作一个在 Eclipse-ee 中的 apache tomcat v8.0 服务器上运行的动态 Web 应用程序，但无法启动服务器。它一直运行良好，然后似乎无缘无故停止了。我是整个网络应用程序的新手，所以如果我做了任何愚蠢的事情，请提前道歉！

这是我在尝试启动服务器时收到的错误消息：

这是服务器概览选项卡：

这是我尝试启动服务器时的控制台输出。有一些错误，但我不明白它们的意思：

最后是 web.xml 文件。我没有改变它，所以我希望这很好：

【问题讨论】：

    标签： java eclipse tomcat web server


    【解决方案1】：

    我相信这是问题

    引起：java.lang.IllegalArgumentException：servlet 命名为 [LoginCheck] 和 [Registration] 都映射到 url-pattern [/LoginCheck] 这是不允许的

    将 servlet 更改为具有 2 个单独的路径。

    【讨论】：

      【解决方案2】：

      您有多个 servlet 映射到同一个 URL：

      Caused by: java.lang.IllegalArgumentException: The servlets named [LoginCheck] and [Registration] are both mapped to the url-pattern [/LoginCheck] which is not permitted

      可能是复制粘贴错误，您可能应该将您的网址更改为Registration
