Failed to bind properties under spring.servlet.multipart.max-file-size to org.springframework.util

前言:在使用Spring Boot2.0+版本时,配置了文件上传的yml,启动时报错如图一所示

完成目标:
1、无法启动项目报错

2、maven配置截图

3、解决方案

一、错误信息:

Description:

Failed to bind properties under ‘spring.servlet.multipart.max-file-size’ to org.springframework.util.unit.DataSize:

Property: spring.servlet.multipart.max-file-size
Value: 30mb
Origin: class path resource [application.yml]:22:22
Reason: failed to convert java.lang.String to org.springframework.util.unit.DataSize

Action:

Update your application’s configuration

图一:
Failed to bind properties under spring.servlet.multipart.max-file-size to org.springframework.util_第1张图片

二、maven配置截图

Failed to bind properties under spring.servlet.multipart.max-file-size to org.springframework.util_第2张图片

三、解决方案

spring:
servlet:
multipart:
max-file-size: 30mb
max-request-size: 30mb

改为

spring:
servlet:
multipart:
max-file-size: 30MB
max-request-size: 30MB

Failed to bind properties under spring.servlet.multipart.max-file-size to org.springframework.util_第3张图片

好了,这样就解决了~
