更新時間：2024年10月31日 14:49:59 作者：Xiao_zuo_ya

本文主要介紹了如何通過Docker安裝Minio并進行訪問測試,同時也講解了如何在SpringBoot中上傳文件到Minio,內(nèi)容包含了pom文件引入依賴,application.properties配置,Minio配置,MinioClinet,FileService,FileServiceImpl的配置

Docker安裝Minio

docker pull minio/minio
docker images
REPOSITORY    TAG       IMAGE ID       CREATED      SIZE
minio/minio   latest    162489e21d26   7 days ago   165MB
nginx         latest    7f553e8bbc89   7 days ago   192MB
# 外掛磁盤存儲使用
mkdir -p /usr/local/minio/data
# 外掛配置文件使用
mkdir -p /usr/local/minio/config
# 創(chuàng)建minio 容器
docker run -d   --name minio   -p 9000:9000   -p 9001:9001   -v /usr/local/minio/data:/data   -v /usr/local/minio/config:/root/.minio   -e MINIO_ROOT_USER=admin   -e MINIO_ROOT_PASSWO
RD=admin   minio/minio server /data --console-address ":9001"
# 創(chuàng)建失敗
docker logs minio
FATAL Unable to validate credentials inherited from the shell environment: Invalid credentials
      > Please provide correct credentials
      HINT:
        MINIO_ROOT_USER length should be at least 3, and MINIO_ROOT_PASSWORD length at least 8 characters
# 密碼不能少于8個字符
docker rm minio
docker run -d   --name minio   -p 9000:9000   -p 9001:9001   -v /usr/local/minio/data:/data   -v /usr/local/minio/config:/root/.minio   -e MINIO_ROOT_USER=admin   -e MINIO_ROOT_PASSWO

SpringBoot上傳文件到Minio

pom文件引入依賴

     <dependency>
         <groupId>io.minio</groupId>
         <artifactId>minio</artifactId>
         <version>8.5.2</version>
     </dependency>

application.properties配置Minio

spring.minio.access-key=pNehtjUDw9ENBlULVTGT
spring.minio.secret-key=p3yVngZ2Ei1uCtn6vKozrof6ICB7GFBiYPr5RAWW
spring.minio.endpoint=http://192.168.10.227:9000

配置MinioClinet

@Data
@Configuration
@ConfigurationProperties(prefix = "spring.minio")
@Slf4j
public class MinioConfig {

    private String accessKey;
    private String secretKey;
    private String endpoint;

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

FileService

public interface FileService {

    /**
     * 是否存在桶
     */
    Boolean bucketExists(String bucketName);

    /**
     * 創(chuàng)建桶
     */
    void makeBucket(String bucketName);

    /**
     * 刪除桶
     */
    void removeBucket(String bucketName);

    /**
     * 獲取當所有桶
     */
    List<Bucket> getAllBuckets();

    /**
     *  上傳文件
     */
    String uploadFile(String bucketName, String prefix, MultipartFile file) throws Exception;

    /**
     * 文件預(yù)覽
     */
    String preview(String bucketName, String prefix, String fileName) throws Exception;

    /**
     * 文件下載
     */
    void download(String bucketName, String prefix, String fileName, HttpServletResponse res);

    /**
     * 刪除文件
     */
    Boolean removeFile(String bucketName, String prefix, String fileName);

    /**
     * 文件是否存在
     */
    boolean isFileExists(String bucketName, String prefix, String fileName) throws Exception;

    /**
     * 生成一個帶到期時間、簽名的URL，這個地址可以提供給沒有登錄的第三方共享訪問或者上傳對象，針對于Bucket為私有的情況
     */
    String getPresignedObjectUrl(String bucketName, String prefix, String fileName);
}
