Increase HTTP Post maxPostSize in Spring Boot

Question

I\'ve got a fairly simple Spring Boot web application, I have a single HTML page with a form with enctype=\"multipart/form-data\". I\'m getting this error:

Answer 1

If you are using using x-www-form-urlencoded mediatype in your POST requests (as I do), the multipart property of spring-boot does not work. If your spring-boot application is also starting a tomcat, you need to set the following property in your application.properties file:

# Setting max size of post requests to 6MB (default: 2MB)
server.tomcat.max-http-post-size=6291456

I could not find that information anywhere in the spring-boot documentations. Hope it helps anybody who also sticks with x-www-form-urlencoded encoding of the body.
