Minio Windows安装和使用

windows 服务端下载地址
https://dl.minio.io/server/minio/release/windows-amd64/minio.exe
安装启动
在cmd窗口中，命令行进行minio.exe所在的文件夹，输入如下命令 server后面的地址是你图片上传之后的存储目录

.\minio.exe server E:\minio

访问默认ip地址http://localhost:9000/minio/login，默认账号密码都是minioadmin

Java客户端

首先创建一个Springboot项目，在resources中的application.yml文件添加如下配置：

server:
  port: 8080
  
spring:
  servlet:
    multipart:
      enabled: true #开启文件上传
      max-file-size: 500MB
      max-request-size: 500MB

minio:
  endpoint: http://localhost:9000 #Minio服务所在地址
  bucketName: tcc #存储桶名称
  accessKey: tanchuntcc #访问的key
  secretKey: tanchuntcc #访问的秘钥

添加minio的maven依赖：

 <dependency>
      <groupId>io.minio</groupId>
      <artifactId>minio</artifactId>
      <version>3.0.10</version>
    </dependency>

controller的代码如下：

@RestController("/minioDemo")
public class MinioDemoController {

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

    @Value("${minio.endpoint}")
    private  String ENDPOINT;
    @Value("${minio.bucketName}")
    private  String BUCKETNAME;
    @Value("${minio.accessKey}")
    private  String ACCESSKEY;
    @Value("${minio.secretKey}")
    private  String SECRETKEY;

    //文件创建
    @PostMapping
    public String upload(MultipartFile file) {
        String s=null;
        try {
            MinioClient minioClient = new MinioClient(ENDPOINT, ACCESSKEY, SECRETKEY);
            //存入bucket不存在则创建，并设置为只读
            if (!minioClient.bucketExists(BUCKETNAME)) {
                minioClient.makeBucket(BUCKETNAME);
                minioClient.setBucketPolicy(BUCKETNAME, "*.*", PolicyType.READ_ONLY);
            }
            String filename = file.getOriginalFilename();
            SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
            // 文件存储的目录结构
            String objectName = sdf.format(new Date()) + "/" + filename;
            // 存储文件
            minioClient.putObject(BUCKETNAME, objectName, file.getInputStream(), file.getContentType());
            LOGGER.info("文件上传成功!");
            s=ENDPOINT + "/" + BUCKETNAME + "/" + objectName;
        } catch (Exception e) {
            LOGGER.info("上传发生错误: {}！", e.getMessage());
        }
        return s;
    }

    //文件删除
    @DeleteMapping
    public String delete(String name) {
        try {
            MinioClient minioClient = new MinioClient(ENDPOINT, ACCESSKEY, SECRETKEY);
            minioClient.removeObject(BUCKETNAME, name);
        } catch (Exception e) {
            return "删除失败"+e.getMessage();
        }
        return "删除成功";
    }
}

    @GetMapping
    public void downloadFiles(@RequestParam("filename") String filename, HttpServletResponse httpResponse) {

        try {

            MinioClient minioClient = new MinioClient(ENDPOINT, ACCESSKEY, SECRETKEY);
            InputStream object = minioClient.getObject(BUCKETNAME, filename);
            byte buf[] = new byte[1024];
            int length = 0;
            httpResponse.reset();

            httpResponse.setHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode(filename, "UTF-8"));
            httpResponse.setContentType("application/octet-stream");
            httpResponse.setCharacterEncoding("utf-8");
            OutputStream outputStream = httpResponse.getOutputStream();
            while ((length = object.read(buf)) > 0) {
                outputStream.write(buf, 0, length);
            }
            outputStream.close();
        } catch (Exception ex) {
            LOGGER.info("导出失败：", ex.getMessage());
        }
    }

编写好demo程序后使用postman进行测试：使用postman文件上传时选择body中的form-data选项，然后属性栏里面选择file属性就可以实现文件上传了。
