SpringBoot报错：The field file exceeds its maximum permitted size of 1048576 bytes

报错信息

The field file exceeds its maximum permitted size of 1048576 bytes

原因是 SpringBoot内嵌的 tomcat 默认的所有上传的文件大小为 1MB

解决办法

修改配置

spring:
  servlet:
    multipart:
      max-file-size: 50MB
      max-request-size: 50MB

或者

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

参考 【异常】The field file exceeds its maximum permitted size of 1048576 bytes.
