MultipartException Current request is not a multipart request

Question

I am trying to make a restful controller to upload files  I have seen this  and made this controller    RestController public class MaterialController         RequestMapping value   upload   method  RequestMethod POST      public String handleFileUpload               RequestParam  file   MultipartFile file           String name    test11           if   file isEmpty                  try                   byte   bytes   file getBytes                    BufferedOutputStream stream                           new BufferedOutputStream new FileOutputStream new File name    -uploaded                      stream write bytes                   stream close                    return  You successfully uploaded     name     into     name    -uploaded                   catch  Exception e                    return  You failed to upload     name       gt      e getMessage                            else               return  You failed to upload     name     because the file was empty                        and then i used postman to send a pdf     But the server crashes with the error    MultipartException  Current request is not a multipart request   Again i have found this  and added a bean xml file   lt  xml version  1 0  encoding  UTF-8   gt   lt beans xmlns  http   www springframework org schema beans         xmlns xsi  http   www w3 org 2001 XMLSchema-instance         xsi schemaLocation  http   www springframework org schema beans http   www springframework org schema beans spring-beans xsd  gt        lt bean id  multipartResolver            class  org springframework web multipart commons CommonsMultipartResolver  gt       lt  bean gt   lt  beans gt    Unfortunately  it still complains with the same error

That happened once to me  I had a perfectly working Postman configuration  but then  without changing anything  even though I didn t inform the Content-Type manually on Postman  it stopped working  following the answers to this question  I tried both disabling the header and letting Postman add it automatically  but neither options worked  I ended up solving it by going to the Body tab  change the param type from File to Text  then back to File and then re-selecting the file to send  somehow  this made it work again  Smells like a Postman bug  in that specific case  maybe

Check the file which you have selected in the request   For me i was getting the error because the file was not present in the system  as i have imported the request from some other machine

When you are using Postman for multipart request then don t specify a custom Content-Type in Header  So your Header tab in Postman should be empty  Postman will determine form-data boundary  In Body tab of Postman you should select form-data and select file type  You can find related discussion at https   github com postmanlabs postman-app-support issues 576

in ARC  advanced rest client  - specify as below to make it work Content-Type multipart form-data   this is header name and header value  this allows you to add form data as key and values  you can specify you field name now as per your REST specification and select your file to upload from file selector

In application properties  please add this   spring servlet multipart max-file-size 128KB spring servlet multipart max-request-size 128KB spring http multipart enabled false   and in your html form  you need an   enctype  multipart form-data   For example    lt form method  POST  enctype  multipart form-data  action     gt    Hope this help

It looks like the problem is request to server is not a multi-part request  Basically you need to modify your client-side form  For  example    lt form action       method  post  enctype  multipart form-data  gt     lt input type  file  name  file    gt   lt  form gt    Hope this helps

I was also facing the same issue with Postman for multipart  I fixed it by doing the following steps    Do not select Content-Type in the Headers section   In Body tab of Postman you should select form-data and select file type    It worked for me
