spring boot报错：the field file exceeds its maximum permitted size

在spring boot的上传文件时报错，the field file exceeds its maximum permitted size

原因：上传文件大小超过的tomcat的最大允许范围

解决办法： 在application.yaml文件中，增加两个行配置信息,servlet.multipart.max-file-size

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/xiaobai?serverTimezone=GMT%2b8
    username: root
    password: mysql
  servlet:
    multipart:
      max-file-size: 10MB
      max-request-size: 50MB
