我使用spring mvc + spring boot hibernate。在我运行应用程序之前突然出现这个错误。下面是错误mesage得到错误java：找不到符号类

C：\用户\ User_2 \ PDRM \ SRC \主\的java \ COM \示例\ RegisterController.java 错误：(23，19)的java：无法找到符号 符号：类Default_profilesRepository 位置：包com。示例 错误：(33，13)的java：无法找到符号 符号：类Default_profilesRepository 位置：类com.example.RegisterController

这里RegisterController类
