Minio 整合springboot 开发 实现文件上传

Minio 作为对象存储，灵活方便，结合java 实现minio 文件上传

1.搭建maven环境，添加依赖包

<properties>    <minio.version>4.0.0</minio.version></properties>
<dependency>    <groupId>io.minio</groupId>    <artifactId>minio</artifactId>    <version>${minio.version}</version></dependency>2.书写一个MinioUtils
public class MinioClientUtils {

private static final Logger LOGGER = LoggerFactory.getLogger(MinioClientUtils.class);

private static MinioClientUtils minioClientUtils;

private MinioClient minioClient;

public static void main(String[] args) {        MinioClientUtils.getInstance().createBucketPublic("helo");    }

}
 
}3.工具类已经封装各种上传。4.public void upload(@RequestParam("file") MulipartFile data,String bucketName,String path){String fileName = data.getOriginalFilename();String filePath = path+"/"+fileName;String contentType = data.getContentType();InputStream inputStram = data.getInputStream();MinioClientUtils minioClientUtils = MinioCLinetUtils.getInstance();
minioClientUtils.uploadStream(
bucketName,
filePath,inputStream,contentType
);
}

Springboot如何启用文件上传功能

网上的文章在写 "springboot文件上传" 时,都让你加上模版引擎,我只想说,我用不上,加模版引擎,你是觉得我脑子坏了,还是觉得我拿不动刀了. springboot如何启用文件上传功能: 其实你啥都不用做,直接用就是了.文件上传相关的随着你的webStarter引入,就被引入到你的项目里面了. POM依赖: 代码: 注意事项: springboot文件上传 单个请求包含的文件默认大小:1MB-10MB 请求格式POST 参数格式form-data 如果出错了,请仔细查看报错信息!
