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();
}
