Max limit of MultipartFile in Spring Boot

Question

Is there a maximum file size that spring boot can handle in a MultipartFile upload process. I know that I can set the maxFileSize in the property l

Answer 1

Spring Boot have embbeed Tomcat with it so we don't need to configure it. MULTIPART properties in application-properties will take care of it.

For an external server, the default limit is 50MB. We can see it by opening webapps/manager/WEB-INF/web.xml

MULTIPART properties have been changed according to versions.

Spring Boot 1.3.x and earlier

multipart.max-file-size
multipart.max-request-size

After Spring Boot 1.3.x:

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

After Spring Boot 2.0:

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