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

First, make sure you are using spring.servlet instead of spring.http.

spring:
  servlet:
    multipart:
      max-file-size: 10MB
      max-request-size: 10MB

If you have to use tomcat, you might end up creating EmbeddedServletContainerCustomizer, which is not really nice thing to do.

If you can live without tomat, you could replace tomcat with e.g. undertow and avoid this issue at all.
