springboot 启动后 No mapping found for HTTP request with URI

org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/register/sendValidateCode.html] in DispatcherServlet with name ‘dispatcherServlet’

今天使用springboot的模板技术开发后端界面，在本地环境运行没有问题。但是丢到线上启动服务之后就不停的刷警告日志，看起来特别讨厌。日志信息如下：
