SpringBoot整合MiNIO

进入Minio官网,下载对应的Minio版本

官网安装文档

下载完成之后，启动(windows版)

minio.exe server D:\minio\server

minio.exe server：启动服务

D:\minio\server：设置上传图片存储路径

api：上传图片链接(端口默认9000)

RootUser：账号

RootPass：密码

Console：控制台地址

访问控制台地址：Http://192.168.1.15:50932 进入控制台

创建存储桶

引入依赖

<!--minio-->
        <dependency>
            <groupId>io.minio</groupId>
            <artifactId>minio</artifactId>
            <version>8.0.3</version>
        </dependency>

yml配置

server:
  port: 8099
spring:
  # 配置文件上传大小限制
  servlet:
    multipart:
      max-file-size: 200MB
      max-request-size: 200MB
minio:
#文件上传接口
  endpoint: http://127.0.0.1:9000
  accessKey: minioadmin
  secreTKEy: minioadmin
  #存储通名称
  bucketName: img

配置类（注册minio客户端）

@Data
@Component
public class MinioclientConfig {

    @Value("${minio.endpoint}")
    private String endpoint;

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

    @Value("${minio.secretKey}")
    private String secreKey;

    
    @Bean
    public MinioClient minioClient(){
        return MinioClient.builder()
                .endpoint(endpoint)
                .credentials(accessKey,secreKey)
                .build();
    }
}

        return results;
    }

}

实体类


@Data
public class ObjectItem {
    private String objectName;
    private Long size;
}

编写Controller


@RestController
public class MinioController {
    @Resource
    private MinioUtils minioUtils;
    @Value("${minio.endpoint}")
    private String address;
    @Value("${minio.bucketName}")
    private String bucketName;

    
    @PostMapping("/upload")
    public Object upload(MultipartFile[] files){
        List<String> uploadUrl = new ArrayList<>();
        List<String> upload = minioUtils.upload(files);
        for (String s : upload) {
            uploadUrl.add(address+"/"+bucketName+"/"+s);
        }
        return uploadUrl;
    }

    
    @PostMapping("/remove")
    public Object remove(@RequestBody List<String> imgUrlList){
        Iterable<Result<DeleteError>> img = minioUtils.removeObjects("img", imgUrlList);
        return img;
    }

    
    @GetMapping("/download/{fileName}")
    public Object download(@PathVariable("fileName") String fileName){
        ResponseEntity<byte[]> download = minioUtils.download(fileName);
        return download;
    }
}
