Spring boot+MinIo进行分布式文件服务（工具类+简单测试）

参考文章：springboot 使用 minio

---

一、 安装MinIo

中文官网

二、 yml配置

#minio文件服务
minio:
  url: http://127.0.0.1:9000
  accessKey: minioadmin
  secretKey: minioadmin
  bucketName: hbq

三、Pom依赖

	io.minio
	minio
	7.0.2

四、MinIoUtil

package com.yk.i_wms.util;

@Slf4j
@Component
public class MinIoUtil {

    private static MinioClient minioClient;

    @Value("${minio.url}")
    private String url;
    @Value("${minio.accessKey}")
    private String accessKey;
    @Value("${minio.secretKey}")
    private String secretKey;
    @Value("${minio.bucketName}")
    private String bucketName;

五、Test

package com.yk.i_wms.common.controller;

@RestController
@RequestMapping("/test")
public class TestController {

    @PostMapping("/createBucket")
    public void createBucket(String bucketName)  {
        MinIoUtil.createBucket(bucketName);
    }

    @PostMapping("/upload")
    public Object upload (String bucketName,@RequestParam("file") MultipartFile multipartFile)  {
        return MinIoUtil.upload(bucketName,multipartFile);
    }
    @PostMapping("/download")
    public void download (String bucketName,String fileName, HttpServletResponse response)  {
        MinIoUtil.download(bucketName,fileName,response);
    }
    @PostMapping("/deleteFile")
    public void deleteFile (String bucketName,String fileName)  {
        MinIoUtil.deleteFile(bucketName,fileName);
    }
}
