Max limit of MultipartFile in Spring Boot

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 like multipart.maxFileSize=1Mb.

So, like that can I allow a huge file to upload, like 50MB. The application runs on the Tomcat server integrated with Spring Boot. Do I need to configure the tomcat server also? Or is the file size unlimited?

as far as I know, it's better to set maxFileSize and maxRequestSize... good question anyway! - Ivan Aracki
i want to what is the maxfile size it can handle. - Ravindu
Unlimited is never a good thing for stuff like this. Better to set it to a large number - bigger than you would ever expect. Someone uploads a file larger than that, and it may very well be an attack, and you'll be grateful for that IllegalStateException that saved your site. - Tony the Tech

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.

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

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

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

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

I am still looking for the answer, What is maximum size we can upload with multiPartFile in springboot application but i have used 450mb successfully and it took approx 10min to do that. Below is the only configuration i did in application.properties file to make it work :

spring.servlet.multipart.max-file-size=500MB
spring.servlet.multipart.max-request-size=500MB
