Spring upload file size limit error

Question

I am using Spring Boot and I can send images that are smaller than 1MB, but when I make a post request with a large image larger than 1MB I get this error:

Maximum upload size exceeded; nested exception is java.lang.IllegalStateException:org.apache.tomcat.util.
http.fileupload.FileUploadBase$FileSizeLimitExceededException: The field file exceeds its maximum permitted size of 1048576 bytes.

I have been looking around so many places to try to find the answer to this error. I have looked at all of these questions and tried implementing what they suggest to no avail: Spring upload file size limit , I am trying to set maxFileSize but it is not honored , org.apache.tomcat.util.http.fileupload.FileUploadBase$FileSizeLimitExceededException , and Max Limit of MultipartFile in spring boot

I am using version 2.0.3 of Spring and here is my post mapping:

    @PostMapping("/post")
    public ResponseEntity<String> handleFileUpload(@RequestParam("file") MultipartFile file) {
      String message = "";
      try {
        storageService.store(file);
        files.add(file.getOriginalFilename());

        message = "You successfully uploaded " + file.getOriginalFilename() + "!";
        return ResponseEntity.status(HttpStatus.OK).body(message);
      } catch (Exception e) {
      message = "FAIL to upload " + file.getOriginalFilename() + "!";
      return ResponseEntity.status(HttpStatus.EXPECTATION_FAILED).body(message);
  }

}

And here are all the application.properties configuration that I have tried:

1

spring.servlet.multipart.max-file-size=-1
spring.servlet.multipart.max-request-size=-1

2

spring.servlet.multipart.max-file-size=5MB
spring.servlet.multipart.max-request-size=5MB

3

spring.http.multipart.max-file-size=5MB
spring.http.multipart.max-request-size=5MB

4

multipart.max-file-size=5MB
multipart.max-request-size=5MB

5

server.tomcat.max-file-size=5000000

6

server.tomcat.max-http-post-size=5000000

7

spring.servlet.multipart.maxFileSize=-1
spring.servlet.multipart.maxRequestSize=-1

Even tried changing it to application.yml:

spring:
  servlet:
    multipart:
      max-file-size: 5MB
      max-request-size: 5MB

I also looked into changing the request size allowed by Tomcat in web.xml file, but I don't have a web.xml file. The Tomcat I am using is bundled in to the app.

Answer 1

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

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

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

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

Answer 2

As per latest Spring Boot Common properties below should work

MULTIPART (MultipartProperties)

spring.servlet.multipart.enabled=true # Whether to enable support of multipart uploads.
spring.servlet.multipart.file-size-threshold=0 # Threshold after which files are written to disk. Values can use the suffixes "MB" or "KB" to indicate megabytes or kilobytes, respectively.
spring.servlet.multipart.location= # Intermediate location of uploaded files.
spring.servlet.multipart.max-file-size=1MB # Max file size. Values can use the suffixes "MB" or "KB" to indicate megabytes or kilobytes, respectively.
spring.servlet.multipart.max-request-size=10MB # Max request size. Values can use the suffixes "MB" or "KB" to indicate megabytes or kilobytes, respectively.
spring.servlet.multipart.resolve-lazily=false # Whether to resolve the multipart request lazily at the time of file or parameter access.

or If you just want to control the multipart properties then multipart.max-file-size and multipart.max-request-size properties should work.

multipart.max-file-size=5MB
multipart.max-request-size=5MB

Answer 3

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

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

Spring Boot 2.x / above:

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

Answer 4

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

Answer 5

Did you try this ?

spring.http.multipart.maxFileSize = 20MB
spring.http.multipart.maxRequestSize = 20MB

OR

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

Works for me with Spring Boot 1.5.x

Answer 6

This worked for me.
We can make changes to file size either in
1. application.properties 2. TOMCAT configuration(server.xml)

A. Ideally we should make use of application.properties 
B. And for that first we need to disable in TOMCAT config file "server.xml" by setting maxSwallowSize=-1 .

    <Connector port="8080" protocol="HTTP/1.1"
      connectionTimeout="20000"
      redirectPort="8443"
      maxSwallowSize = "-1"/>

C. Then set application.properties as

spring.servlet.multipart.max-file-size=15MB
spring.servlet.multipart.max-request-size=15MB
spring.servlet.multipart.enabled=true

Answer 7

Refer org.springframework.boot.autoconfigure.web.MutltipartProperties class to understand what prefix to use when setting the property. All the above naming convention works for different versions of springframework.
