The servlets named [create_subscription] and [servlet.create] are both mapped to the url-pattern

原因，代码中在public前已经有了默认的配置路径：

如：

@WebServlet("/ShowUser")
public class ShowUser extends HttpServlet

如果在xml中继续配置则会出项

The servlets both mapped to the url-pattern 错误

一般理解把其一干掉即可。

如注销xml中的路径，问题解决：

The servlets named [create_subscription] and [servlet.create] are both mapped to the url-pattern

但是注释掉java中的默认路径配置或删除默认路径均无效：

The servlets named [create_subscription] and [servlet.create] are both mapped to the url-pattern
