Failed to load resource: the server responded with a status of 413 (Request Entity Too Large)【上传图片】

1、错误描述

Failed to load resource: the server responded with a status of 413 (Request Entity Too Large)

2、错误原因与解决方法

      1.上传文件时，利用localhost访问系统，不会出现这个问题；用域名访问这个系统时，出现这个问题，提示是：请求实体太大由于Nginx反向代理服务器client_max_body_size默认值为1MB，而上传文件大于1MB，所以就出现这个错误

       2.Springboot中，上传文件大小限制过小。       

#控制文件上传的大小
spring.servlet.multipart.max-file-size=100MB
spring.servlet.multipart.max-request-size=1000MB
