I'm a beginner who studies spring.
I added code for INSERT to the controller (FILE UPLOAD), but that error occurs. I ask for your help
spring spring-boot mybatis java sql
message Request processing failed; nested exception is java.lang.ClassCastException: org.apache.catalina.connector.RequestFacade cannot be cast to org.springframework.web.multipart.MultipartHttpServletRequest
There is an exact cause of the error.
Error transforming org.apache.catalina.connector.RequestFacade to org.springframework.web.multipart.MultipartHttpServletRequest.
Check the code.
