When uploading a file to a SpringBoot Application, you will get the following exception for files over 1 Mb size :

Maximum upload size exceeded; nestedexception is java.lang.IllegalStateException:org.apache.tomcat.util.http.fileupload.impl.FileSizeLimitExceededException: The field fileexceeds its maximum permitted size of1048576 bytes.

These are the default Spring Boot limits. To increase these limits to 10 Mb, with Spring Boot 2, add the following lines to your application.properties file:

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