SpringBoot上传文件大小受限问题怎么解决

org.springframework.web.multipart.MaxUploadSizeExceededException: Maximum upload size exceeded; nested exception is java.lang.IllegalStateException: org.apache.tomcat.util.http.fileupload.FileUploadBase$FileSizeLimitExceededException: The field file exceeds its maximum permitted size of 1048576 bytes.

#做限制的参数配置
spring:
  servlet:
    multipart:
      enabled: true #默认支持文件上传
      max-file-size: 20MB # 最大支持文件大小
      max-request-size: 30MB # 最大支持请求大小

#不做限制的参数配置
spring:
  servlet:
    multipart:
      enabled: true #默认支持文件上传
      max-file-size: -1 #不做限制
      max-request-size: -1 #不做限制
