How to set the max size of upload file

Question

I\'m developing application based on Spring Boot and AngularJS using JHipster. My question is how to set max size of uploading files?

If I\'m trying

Answer 1

I know this is extremely late to the game, but I wanted to post the additional issue I faced when using mysql, if anyone faces the same issue in future.

As some of the answers mentioned above, setting these in the application.properties will mostly fix the problem

spring.http.multipart.max-file-size=16MB
spring.http.multipart.max-request-size=16MB

I am setting it to 16 MB, because I am using mysql MEDIUMBLOB datatype to store the file.

But after fixing the application.properties, When uploading a file > 4MB gave the error: org.springframework.dao.TransientDataAccessResourceException: PreparedStatementCallback; SQL [insert into test_doc(doc_id, duration_of_doc, doc_version_id, file_name, doc) values (?, ?, ?, ?, ?)]; Packet for query is too large (6656781 > 4194304). You can change this value on the server by setting the max_allowed_packet' variable.; nested exception is com.mysql.jdbc.PacketTooBigException: Packet for query is too large (6656781 > 4194304). You can change this value on the server by setting the max_allowed_packet' variable.

So I ran this command from mysql:

SET GLOBAL max_allowed_packet = 1024*1024*16;
