Uploaded files are deleted using Apache Commons FileupLoad and Spring MVC

Uploaded files are deleted using Apache Commons FileupLoad and Spring MVC

I am new to Spring, and I want to use the Apache Commons FileUpload
library. The upload works, but the uploaded file eventually is deleted. I
looked at the FileUpload documentation, and it states that once the file
is no longer being referenced, it will be garbage collected.
I have a controller that I use to process the upload. I tried uploading
the file to a temp directory I created under the context root,
mywebapp\temp. Once the file is uploaded it eventually gets deleted. I
tried moving it to another directory after it was uploaded,
mywebapp\upload\images. The file still gets deleted. I'm not sure what I
am doing wrong.
Thanks for any help!
FileUploadController.java
@RequestMapping(value="uploadFile.request", method=RequestMethod.POST)
protected String uploadFile {@ModelAttribute("uploadForm")UploadForm
uploadForm, BindingResult result
if(!result.hasErrors()) {
CommonsMultipartFile multipartFile = uploadForm.getMultipartFile();
// Make sure the file has content.
if(multipartFile != null && multipartFile.getSize() > 0) {
FileItem item = multipartFile.getFileItem();
// Absolute file path to the temp directory
String tempDirectoryPath =
context.getInitParameter("TempDirectoryPath");
// Absolute file path to the upload directory
String uploadDirectoryPath =
context.getInitParameter("UploadDirectoryPath");
// Upload to temp directory
File uploadFile = new File(tempDirectoryPath + File.separator
+ fileName);
fileItem.write(uploadFile);
// Move the file to its final destination
FileUtils.moveFileToDirectory(uploadFile, new
File(uploadDirectoryPath), true);
}
return "nextPage";
}
UploadForm.java

this.name = name;
}

return multipartFile;
}

this.multipartFile = multipartFile;
this.name = multipartFile.getOriginalFilename();
}
