Spring upload file size limit error

Add the below lines in application.properties for Spring Boot version 2.0.0.RELEASE and above -

spring.servlet.multipart.max-file-size=128MBspring.servlet.multipart.max-request-size=128MBspring.servlet.multipart.enabled=true

Please note for lower versions, i.e. 1.5.9.RELEASE and below the configuration used to be as follows:

spring.http.multipart.max-file-size = 20MBspring.http.multipart.max-request-size = 20MB

Dependes on Spring boot Version , example 1.X, on your application.properties, set the file size limit:

spring.http.multipart.max-file-size=128KBspring.http.multipart.max-request-size=128KB

Spring Boot 2.x / above:

spring.servlet.multipart.max-file-size=10MBspring.servlet.multipart.max-request-size=10MB

This is what I have and it works perfectly for me for the backend.

@PutMapping(value = USER_PROFILE_UPDATE_URL_MAPPING)  public String updateProfile(      @ModelAttribute(AUTHORIZED_USER_MODEL_KEY) User user,      BindingResult bindingResult,      @RequestParam(name = "file") MultipartFile multipartFile,      Model model, @RequestParam Map<String, String> params) {    Authentication authentication = SecurityContextHolder.getContext().getAuthentication();    User authorizedUser = (User) authentication.getPrincipal();    //....       return REDIRECT_TO_LOGIN;    }

And in the bootstrap.yml file, I will simply have something like this...which will only allow the maximum file size of 2 megabytes.

---spring:  servlet:    multipart:      max-file-size: 2MB      max-request-size: 2MB

and finally, in my HTML file, I will have something like this...

<form id="profileForm"   th:action="@{/update}"   th:object="${user}"   method="post" enctype="multipart/form-data">   <!-- This will modify the method to PUT to match backend -->   <input type="hidden" name="_method" value="PUT">   ...   <div class="col-md-3">      <div class="form-group row">         <label for="file" class="custom-file">           <input name="file" type="file" id="file" aria-describedby="fileHelpId"  class="form-control-file btn btn-outline-info">          </label>          <small id="fileHelpId" class="form-text text-muted">Maximum size should be 2MB</small>       </div>   </div>

And this should work perfectly fine. I am also using Spring Boot 2.0.3
