Charlie :
I am doing file upload with Spring Boot and I am getting the following error.
Could not parse multipart servlet request; nested exception is java.io.IOException: org.apache.tomcat.util.http.fileupload.FileUploadBase$IOFileUploadException: Processing of multipart/form-data request failed. Connection reset by peer
I searched for this error and found this article which says this error occurs when user tries to upload a file which is larger than the specified limit.
But for my application this scenario is not possible because I check the file size in the UI code before uploading the file.
Here is my file upload controller:
@RequestMapping(value = "fileUpload", method = RequestMethod.POST)
public ResponseEntity<?> uploadFile(@RequestParam("uploadedFile") MultipartFile uploadedFile,
PersistentEntityResourceAssembler resourceAssembler) throws IOException {
if (uploadedFile.getSize() / 1024 > MAX_FILE_SIZE) {
throw new CustomConstraintViolationException("File Size exceeds 25 MB");
}
//save file
return new ResponseEntity<>(resourceAssembler.toResource(savedFile), HttpStatus.CREATED);
}
I also have file size specified in the application.properties as well.
spring.http.multipart.max-file-size=26240KB
spring.http.multipart.max-request-size=26240KB
So what am I doing wrong?
UPDATE
I am using Spring Boot 1.5.17
UPDATE 2
Here is the full stacktrace

For anyone having the same problem, I found out this error was caused by a timeout set on file uploads by UI and it is not related to Spring. Now this may not be true for all instances of this error so take a look at this article as well.
