Answer 1

The error message tells you this: 错误消息告诉您：

Servlet [com.gym.GymperUI$Servlet] and Servlet [MyUIServlet] have the same url Pattern: [/].

This just means that you have two servlets which try to handle the / URL. 这仅意味着您有两个尝试处理/ URL的servlet。 So either remove the other servlet or make sure they handle separate URL's. 因此，请删除其他servlet或确保它们处理单独的URL。
