Tomcat启动失败，启动子级时出错 IllegalStateException,因为我们有相同的WebServlet注解配置路径，有两个相同的上下文路径，所以会报错。

这是一个关于Tomcat启动Web项目时出现异常的报错信息。报错信息中提到了一个IllegalStateException异常，这个异常通常是由于Tomcat在启动子级时出现了错误导致的。具体来说，这个异常可能是由于以下原因引起的：
- 应用程序的上下文路径已经存在于Tomcat中，但是Tomcat正在尝试将其添加到现有的上下文中。
- 应用程序的上下文路径已经存在于Tomcat中，但是Tomcat正在尝试将其添加到现有的上下文中。
- 应用程序的上下文路径已经存在于Tomcat中，但是Tomcat正在尝试将其添加到现有的上下文中。
解决这个问题的方法可能包括：
- 检查Tomcat的日志文件，查看是否有其他错误或异常。
- 检查应用程序的配置文件，确保没有重复的上下文路径。
- 检查应用程序的依赖项，确保它们都正确地配置和部署。
- 尝试重新启动Tomcat和应用程序，看看是否可以解决问题。
