让tomcat自动部署上下文

我有一个名为'projectx'的项目 . 我的目标是执行 mvn clean install 并让Tomcat使用/ target文件夹自动部署webapp .

我将带有以下内容的projectx.xml添加到/ tomcat / conf / Catalina / localhost /

<?xml version="1.0" encoding="UTF-8"?>
<Context docBase="C:\Users\Username\workspace\projectx-webapp\target" path="/projectx-webapp"/>

我可以在服务器日志中看到成功处理文件projectx.xml . webapp已成功部署 . 网站网址是localhost：8080 / projectx-webapp / . 但是当我转到网址时，找不到网络应用程序 .

当我在tomcat \ webapps中手动部署war文件时，当我转到指定的url时，webapp工作正常 . 我错过了在projectx.xml中配置的东西吗？

我的web.xml：

<web-app id="projectx-webapp" version="2.4"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
