I. Background description

This project is a Springboot project, the function is to do a file upload, and an error is found during the test. The uploaded file is a word file with a size of 1.25MB. The error message is as follows:

Caused by: org.apache.tomcat.util.http.fileupload.FileUploadBase$FileSizeLimitExceededException: The fieldfile exceeds its maximum permitted size of 1048576 bytes.

The detailed error report is shown in the following figure:

Second, the reason for the error

SpringBoot project appears Caused by: org.apache.tomcat.util.http.fileupload.FileUploadBase$FileSizeLimitExceededException: The field file exceeds its maximum permitted size of 1048576 bytes. The error shows that the file size exceeds the allowed range.The reason is that the default size of all uploaded files in SpringBoot's embedded tomcat is 1MB. If this size is exceeded, an error will be reported. To solve this problem, you need to change the following two defaults.

• multipart.maxFileSize
• multipart.maxRequestSize

Three. Solution

The solution should be determined according to the version of SpringBoot. The following lists several situations, which can be corresponded according to the version of SpringBoot of your own project: just modify the default file size limit.The following is the file size limit used in my project, and changing it to 50MB can meet my needs.

Before 3.1 SpringBoot 1.3.x

multipart.maxFileSize=50Mbmultipart.maxRequestSize=50Mb

3.2 SpringBoot 1.4.x

spring.http.multipart.maxFileSize=50Mbspring.http.multipart.maxRequestSize=50Mb

After 3.3 SpringBoot 2.0.x

spring.servlet.multipart.max-file-size=50MBspring.servlet.multipart.max-request-size=50MB

After configuring the above restrictions, restart the project, Bingo, done!!!

It's over!
