问题描述
springboot项目，在做图片上传项目时，上传图片出现下面的异常：
org.springframework.web.multipart.MaxUploadSizeExceededException: Maximum upload size exceeded; nested exception is java.lang.IllegalStateException: org.apache.tomcat.util.http.fileupload.impl.FileSizeLimitExceededException: The field file exceeds its maximum permitted size of 1048576 bytes.

这个错误是因为Spring Boot应用程序接收到的文件大小超过了默认的最大限制。默认情况下，Spring Boot限制上传文件的大小为1MB。
要解决这个问题，你可以通过配置Spring Boot应用程序来增加文件上传的最大限制。
解决方案
修改application.properties或application.yml文件中
application.properties:
spring.servlet.multipart.max-file-size=10MB
spring.servlet.multipart.max-request-size=10MBapplication.yml:
spring:
servlet:
multipart:
max-file-size: 10MB
max-request-size: 10MB
