Rename file while uploading on webapp in spring using MultiPartFile datatype

Question

I have to upload an image from the user interface and change its name according to my need.

i.e. if user uploads an image with a name WIN_20151122_09_57_47_Pro.jpg I would have to change it to 1.jpg

I am using Spring mvc and for file upload and display I am using MultiPartFile datatype

Below is the model.

FileBucket.java

package com.faisal.model;

import org.springframework.web.multipart.MultipartFile ;

public class FileBucket {

      MultipartFile file ;

       public MultipartFile getFile() {
             return file ;
      }

       public void setFile(MultipartFile file ) {
             this.file = file;
      }
}

The controller part where I am uploading the file on the server

@Autowired
      ServletContext servletContext;

@RequestMapping(value = "/singleUpload" , method = RequestMethod.POST)
       public String singleFileUpload(@Valid FileBucket fileBucket,
                  BindingResult result, ModelMap model ) throws IOException {

            String PROFILE_UPLOAD_LOCATION = servletContext.getRealPath("/" )
                        + File. separator + "resources" + File.separator
                        + "profile_images" + File.separator;

             if (result .hasErrors()) {
                  System. out.println("validation errors" );
                   return "singleFileUploader" ;
            } else {
                  System. out.println("Fetching file" );
                  String destination=PROFILE_UPLOAD_LOCATION
                              + fileBucket.getFile().getOriginalFilename();

                  File file = new File(destination);
                  File newFile=new File(PROFILE_UPLOAD_LOCATION +"1.jpg" );


                  FileCopyUtils. copy(fileBucket.getFile().getBytes(), file);
                  FileUtils. moveFile(file, newFile);


                  MultipartFile multipartFile = fileBucket .getFile();
                  String fileName = multipartFile .getOriginalFilename();
                   model.addAttribute("fileName" , fileName );
                   return "success" ;
            }
      }

View page

<body>
       <div class="success" >

       <img src=" ${pageContext.request.contextPath}/resources/profile_images/${fileName} " height ="100" width="100" />
       <br/>
            File <strong> ${fileName}</strong > uploaded successfully.
       </div>

</body>

In the code above I have successfully renamed the file but then while redirecting on the same page the image is not displayed since it has been replaced by 1.jpg

Try `` like this ``. Here's how I implemented [UserController](https://github.com/RawSanj/spring-tiles-sample-app/blob/master/src/main/java/com/sanjay/springtiles/controller/UserController.java) and in jsp view `` — Sanjay Rawat, Mar 25 '16 at 19:43
here is the thing in more simpler way: 1. uploading a file on server (which is accomplished) 2.uploading the file and renaming it at the server side to more appropriate name(This I am trying to accomplish now) — Md Faisal, Mar 25 '16 at 20:54
@SanjayRawat this solved my problem , please write an answer so that I can accept it. — Md Faisal, Mar 27 '16 at 06:43

Try <spring:url> like this <img src='<spring:url value="/resources/profile-pictures/${user.profileImage}" />' >.

Here's how I implemented UserController and in jsp view <img src='<spring:url value="/resources/profile-pictures/${user.profileImage}" />' alt="User Image">
