Answer 1

from documentation: https://spring.io/guides/gs/uploading-files/

Tuning file upload limits

When configuring file uploads, it is often useful to set limits on the size of files. Imagine trying to handle a 5GB file upload! With Spring Boot, we can tune its auto-configured MultipartConfigElement with some property settings.

Add the following properties to your existing src/main/resources/application.properties:

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

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

The multipart settings are constrained as follows:

• spring.http.multipart.max-file-size is set to 128KB, meaning total file size cannot exceed 128KB.

• spring.http.multipart.max-request-size is set to 128KB, meaning total request size for a multipart/form-data cannot exceed 128KB.

Answer 2

In application.properties file write this:

# Max file size.
spring.http.multipart.max-file-size=1Mb
# Max request size.
spring.http.multipart.max-request-size=10Mb

Adjust size according to your need.

Update

Note: As of Spring Boot 2, however you can now do

# Max file size.
spring.servlet.multipart.max-file-size=1MB
# Max request size.
spring.servlet.multipart.max-request-size=10MB
