Spring Boot - Multipart file maximum upload size exception

Question

I'm developing a endpoint with Spring Boot 2.1.3<\/strong> (using the standard Tomcat embedded web server) to upload an image and I want to limit the size of the multipart upload. I can do this easily with the properties:

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

Answer 1

A bit late. You need set in application.properties or application.yml server.tomcat.max-swallow-size=-1 With it tomcat will not interferred in the upload request and the operation will be handle fully by spring and your exception controller will work perfectly. References

Answer 2

Please add this in your application.properties :

spring.servlet.multipart.max-file-size=50MB
spring.servlet.multipart.max-request-size=50MB

You can change the size as you need in the above config

Answer 3

Was having a similar problem. Tomcat kept complaining that the request was exceeding the configured maximum (2097152), even though I had the default settings in place in the global web.xml:

      <max-file-size>52428800</max-file-size>
      <max-request-size>52428800</max-request-size>

Finally figured out: the servlet class I am developing extends a servlet class that has the @MultipartConfig annotation, but my local class did not have the @MultipartConfig annotation. So the request was not being treated as multi-part, which was tripping this error.

The code that was throwing the error is in the super class at these lines:

//Search through the parts for an uploaded file
for (Part part : request.getParts()) {
