Does your handler implement a supported interface like Controller?] with root cause

spring MVC 出现以下错误,是因为我再Controller中,我没有配置

@RequestMapping(method = {RequestMethod.POST,RequestMethod.GET})

严重: Servlet.service() for servlet [auth] in context with path [/Auth2] threw exception [No adapter for handler [com.jin.auth.android.ProtobufferControl@32704b3]: Does your handler implement a supported interface like Controller?] with root cause

javax.servlet.ServletException: No adapter for handler [com.jin.auth.android.ProtobufferControl@32704b3]: Does your handler implement a supported interface like Controller?
