springboot 上传文件设置文件大小限制

报错内容：

org.springframework.web.multipart.MaxUploadSizeExceededException: Maximum upload size exceeded; nested exception is java.lang.IllegalStateException: org.apache.tomcat.util.http.fileupload.impl.SizeLimitExceededException: the request was rejected because its size (39353107) exceeds the configured maximum (10485760)

解决方案：

一   application.yml 添加配置 ：

spring:
  servlet:
    multipart:
      max-request-size: 100MB
      max-file-size: 100MB

二 Application启动类添加bean：

    @Bean
    public MultipartConfigElement multipartConfigElement() {
        MultipartConfigFactory factory = new MultipartConfigFactory();
        //单个文件最大
        factory.setMaxFileSize(DataSize.parse("5MB"));
        /// 设置总上传数据总大小
        factory.setMaxRequestSize(DataSize.parse("20MB"));
        return factory.createMultipartConfig();
    }
