Servlet.service() for servlet [springmvc] in context with path [] threw exception [Request processin

地址栏输入地址没有变化，DeBug没有到控制器，在tomcat日志中报出以下错误

Servlet.service() for servlet [springmvc] in context with path [] threw exception [Request processing failed; nested exception is java.lang.IllegalStateException: Ambiguous handler methods mapped for HTTP path 'http://localhost:5230/gsda1.htm':

出现这样的问题，是因为 url跟其它的控制器的url冲突。
