Spring MVC save uploaded MultipartFile to specific folder

Question

I want to save uploaded images to a specific folder in a Spring 3 MVC application deployed on Tomcat

My problem is that I cannot save the uploaded images files to the host where the appliciation is running.

Here is what I tried:

private void saveFile(MultipartFile multipartFile, int id) throws Exception {     String destination = "/images/" + id + "/"  + multipartFile.getOriginalFilename();     File file = new File(destination);     multipartFile.transferTo(file); } 

Result: FileNotFoundException - Yes sure, I do want create this file!?!

I tried it using the context.getRealPath or getResources("destination"), but without any success.

How can I create a new file in a specific folder of my app with the content of my multipart file?

Answer 1

This code will surely help you.

String filePath = request.getServletContext().getRealPath("/");  multipartFile.transferTo(new File(filePath));

Let's create the uploads directory in webapp and save files in webapp/uploads:

@RestController public class GreetingController {      private final static Logger log = LoggerFactory.getLogger(GreetingController.class);      @Autowired     private HttpServletRequest request;       @RequestMapping(value = "/uploadfile", method = RequestMethod.POST)         public         @ResponseBody         ResponseEntity handleFileUpload(@RequestParam("file") MultipartFile file) {             if (!file.isEmpty()) {                 try {                     String uploadsDir = "/uploads/";                     String realPathtoUploads =  request.getServletContext().getRealPath(uploadsDir);                     if(! new File(realPathtoUploads).exists())                     {                         new File(realPathtoUploads).mkdir();                     }                      log.info("realPathtoUploads = {}", realPathtoUploads);                       String orgName = file.getOriginalFilename();                     String filePath = realPathtoUploads + orgName;                     File dest = new File(filePath);                     file.transferTo(dest); 

the code
String realPathtoUploads = request.getServletContext().getRealPath(uploadsDir);

returns me next path if I run the app from Idea IDE
C:\Users\Iuliia\IdeaProjects\ENumbersBackend\src\main\webapp\uploads\

and next path if I make .war and run it under Tomcat:
D:\Programs_Files\apache-tomcat-8.0.27\webapps\enumbservice-0.2.0\uploads\
