问题描述
我在Tomcat错误日志下面。我已经检查过，没有重复或多个服务器实例在运行。另外，我检查了server.xml并将其调整为从8080到8000的其他端口，但这不能解决问题。
感谢您的时间！

解决方法
不要像在 servlet 中那样在 web.xml 文件和 servlet 中给出相同的路径：
@WebServlet("/don't put same name")
并在您的 web.xml 文件中：
<servlet-mapping>
<servlet-name>spring</servlet-name>
<URL-pattern>/here don't put same path</URL-pattern>
</servlet-mapping>
选择其中任何一个。
