Multipart File Upload:Size exceed exception in spring boot return JSON error message

Question

As I have set maximum file upload limit,I am getting

org.apache.tomcat.util.http.fileupload.FileUploadBase$FileSizeLimitExceededException: The field file exceed         


        

Answer 1

Add a special exception handler into your Controller:

@ExceptionHandler(FileSizeLimitExceededException.class)
public YourReturnType uploadedAFileTooLarge(FileSizeLimitExceededException e) {
    /*...*/
}

(If this does not work, you have to enable exception handling in your configuration. Normally Spring does this by default.)
