Springboot 整合 MinIO

專案通過maven構建首先新增MinIO的maven依賴

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

在resources目錄下建立minio.properties配置檔案，內容如下:

minio.endpoint=http://localhost:9000
minio.accessKey=minioadmin
minio.secretKey=minioadmin
minio.bucketName=demo

在spring boot專案下建立MinioConfig配置類

使用ConfigurationProperties註解載入指定prefix的值 ，使用@PropertiesSource註解指定的配置檔案，將minio.properties中的配置項載入進來

並建立MinioClient交給spring容器管理

@Data
@Component
@ConfigurationProperties(prefix = "minio")
@PropertySource(value = "classpath:minio.properties")
public class MinioConfig {

    private String endpoint;

    private int port;

    private String accessKey;

    private String secretKey;

    private String bucketName;

    @SneakyThrows
    @Bean
    public MinioClient getMinioClient() {
        MinioClient minioClient = new MinioClient(endpoint, accessKey, secretKey);
        return minioClient;
    }

}

建立MinioController，編寫一個上傳檔案的方法

此處的

minioClient.putObject(minioConfig.getBucketName(), objectName, inputStream, MimeTypeUtils.IMAGE_JPEG_VALUE);

後期應寫於sevice層

@RequestMapping("/minio")
@RestController
public class MinioController {

    @Autowired
    private MinioClient minioClient;

    @Autowired
    private MinioConfig minioConfig;


    @PostMapping("upload")
    public String uploadFile(MultipartFile file) throws IOException {
        try {
            String fileName = file.getOriginalFilename();
            String objectName = new SimpleDateFormat("yyyy/MM/dd/").format(new Date()) + UUID.randomUUID().toString().replaceAll("-", "")
                    + fileName.substring(fileName.lastIndexOf("."));
            InputStream inputStream = file.getInputStream();
            minioClient.putObject(minioConfig.getBucketName(), objectName, inputStream, MimeTypeUtils.IMAGE_JPEG_VALUE);
        } catch (Exception e) {
            e.printStackTrace();
            return "上傳失敗";
        }
        return "上傳成功";
    }

}
