SpringBoot 文件上传遇到的错误解决

最近在做文件上传，把遇到的问题和解决办法整理出来：

1、NoClassDefFoundError: org/apache/commons/fileupload/FileItemFactory

这个是因为缺少  commons-fileupload 的包，pom里添加依赖即可解决。

<dependency>
    <groupId>commons-fileupload</groupId>
    <artifactId>commons-fileupload</artifactId>
    <version>1.3.3</version>
</dependency>

2、java.lang.IllegalStateException: org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException: the request was rejected because its size (106882301) exceeds the configured maximum (10485760)

这个需要修改文件上传默认的大小限制。通过以下application.yml的配置项来解决：

multipart:
  maxFileSize: 512Mb
  maxRequestSize: 512Mb
