解决springboot上传大文件失败的问题

在最近通过web上送文件超过1M报错：

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

或者报下面这个错

[dispatcherservlet] throw java io ioexception  stream close

解决方法：

1.spring boot 1.x 版本

spring.http.multipart.maxFileSize = 10Mb

spring.http.multipart.maxRequestSize=100Mb

2.spring boot 2.x 版本

spring.servlet.multipart.max-file-size=10MB
spring.servlet.multipart.max-request-size=100MB

配置后重启系统即可
