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-config>
   <max-file-size>52428800</max-file-size>
   <max-request-size>52428800</max-request-size>
   <file-size-threshold>0</file-size-threshold>
</multipart-config>

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 

Answer 2

Setting multipart.max-file-size=128MB and multipart.max-request-size=128MB works for me without additional configuration.

Answer 3

For those using Spring Boot 2.0 (as of M1 release), the property names have changed to:

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

Note the prefix is spring.servlet instead of spring.http.

Answer 4

For unlimited upload file size

It seems setting -1 will make it for infinite file size.

Before Spring Boot 2.0:

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

Answer 5

In my application.yml file

spring:
 servlet:
    multipart:
      max-file-size: 15MB
      max-request-size: 15MB

And If you have application.properties file

spring.servlet.multipart.max-file-size = 15MB
spring.servlet.multipart.max-request-size = 15MB

Even You can set file size to infinite

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