文档说明表示，每个文件的配置最大为1Mb，单次请求的文件的总数不能大于10Mb。要更改这个默认值需要在配置文件（如application.properties）中加入两个配置

 

1. multipart.maxFileSize = 10Mb
   
2. multipart.maxRequestSize=100Mb
   

multipart.maxFileSize=10Mb是设置单个文件的大小, multipart.maxRequestSize=100Mb是设置单次请求的文件的总大小

如果是想要不限制文件上传的大小，那么就把两个值都设置为-1就行啦

*****************************后续更新******************************如果有误，请查看文末提示官方文档哈

Spring Boot1.4版本后配置更改为:

 

1. spring.http.multipart.maxFileSize = 10Mb
   
2. spring.http.multipart.maxRequestSize=100Mb
   

Spring Boot2.0之后的版本配置修改为:

 

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

详情参考Spring Boot官方文档，感谢评论的小伙伴给出的建议更新提示。

**************

重要：根据评论区的老铁们给的提示，如果以上的配置有误，尝试将=更改为:或者将Mb单位更改为MB，大家以Spring Boot的官方文档为准哈，如果博文给大家带来麻烦，还请谅解，因为Spring Boot版本迭代很快，我已经很久没有接触了哈，谢谢大家，谢谢评论区的小伙伴。
