Spring Boot:The field file exceeds its maximum permitted size of 1048576 bytes.

Spring Boot做文件上传时出现了The field file exceeds its maximum permitted size of 1048576 bytes.错误，显示文件的大小超出了允许的范围。

可以修改配置文件来修改限制文件大小

Spring Boot1.4版本后配置更改为:

spring.http.multipart.maxFileSize = 10Mb 
spring.http.multipart.maxRequestSize=100Mb 

Spring Boot2.0之后的版本配置修改为:

spring.servlet.multipart.max-file-size=10MB
spring.servlet.multipart.max-request-size=100MB
