MinIO
MinIO基于Apache License v2.0开源协议的对象存储服务,可以做为云存储的解决方案用来保存海量的图片,视频,文档。

快速入门
使用docker 安装:
docker search minio
- 拉取镜像:
docker pull minio/minio
- 运行(无法访问):
docker run -p 9000:9000 --name minio -d --restart=always \
-e "MINIO_ACCESS_KEY=minio" \
-e "MINIO_SECRET_KEY=minio123" \
-v ~/tools/docker-volumes/minio:/data \
-v ~/tools/docker-volumes/minio-config:/root/.minio \
minio/minio server /data
参数解释:
-v ~/tools/docker-volumes/minio:/data
表示将本地系统中的~/tools/docker-volumes/minio
目录挂载到 MinIO 容器中的/data
目录。-v ~/tools/docker-volumes/minio-config:/root/.minio
表示将本地系统中的~/tools/docker-volumes/minio-config
目录挂载到 MinIO 容器中的/root/.minio
目录。9000:9000
是将本地系统的9000端口映射到MinIO容器的9000端口,以便通过该端口访问MinIO服务。server /data
部分表示在MinIO容器内运行MinIO服务器,并将数据存储在容器内的/data
目录。
此时如果启动会发现访问本地的localhost:9000
会自动跳转到其他静态端口,例如我的是:33625
找到,发现需要 设置两个端口,
成功运行的命令如下:
docker run -p 9000:9000 -p 9090:9090 \
--name minio -d --restart=always \
-e "MINIO_ACCESS_KEY=minio" \
-e "MINIO_SECRET_KEY=minio123" \
-v ~/tools/docker-volumes/minio:/data \
-v ~/tools/docker-volumes/minio-config:/root/.minio \
minio/minio server /data --console-address ":9090"
此时发现端口对应 上了:
可以 正常访问:
基本概念说明:
- Bucket 类似于文件系统的目录
- Object类似于文件系统的文件
- keys类似于文件名
Springboot中使用
依赖:
<dependencies>
<dependency>
<groupId>io.minio</groupId>
<artifactId>minio</artifactId>
<version>7.1.0</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
</dependency>
</dependencies>
进行上传之前先设置一下权限:
public class MinIOTest {
public static final String MY_FILE = "/tmp/list.html";
public static final String ACCESS_KEY = "minio";
public static final String SECRET_KEY = "minio123";
public static void main(String[] args) {
FileInputStream fileInputStream = null;
try {
fileInputStream = new FileInputStream(MY_FILE);
//1.创建minio链接客户端
MinioClient minioClient = MinioClient.builder().credentials(ACCESS_KEY, SECRET_KEY)
.endpoint("http://localhost:9000").build();
//2.上传
PutObjectArgs putObjectArgs = PutObjectArgs.builder()
.object("list.html")//文件名
.contentType("text/html")//文件类型
.bucket("leadnews")//桶名词 与minio创建的名词一致
.stream(fileInputStream, fileInputStream.available(), -1) //文件流
.build();
minioClient.putObject(putObjectArgs);
System.out.println("http://localhost:9000/leadnews/list.html");
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
运行代码,此时可以进行访问.http://localhost:9000/leadnews/list.html
封装为starter
配置类:
@Data
@ConfigurationProperties(prefix = "minio") // 文件上传 配置前缀file.oss
public class MinIOConfigProperties implements Serializable {
private String accessKey;
private String secretKey;
private String bucket;
private String endpoint;
private String readPath;
}
@Data
@Configuration
@EnableConfigurationProperties({MinIOConfigProperties.class})
//当引入FileStorageService接口时
@ConditionalOnClass(FileStorageService.class)
public class MinIOConfig {
@Autowired
private MinIOConfigProperties minIOConfigProperties;
@Bean
public MinioClient buildMinioClient() {
return MinioClient
.builder()
.credentials(minIOConfigProperties.getAccessKey(), minIOConfigProperties.getSecretKey())
.endpoint(minIOConfigProperties.getEndpoint())
.build();
}
}
业务实现:

/**
* 上传html文件
* @param prefix 文件前缀
* @param filename 文件名
* @param inputStream 文件流
* @return 文件全路径
*/
public String uploadHtmlFile(String prefix, String filename,InputStream inputStream);
/**
* 删除文件
* @param pathUrl 文件全路径
*/
public void delete(String pathUrl);

*/
public byte[] downLoadFile(String pathUrl);

在其他模块中使用:
- 导入依赖:
<dependency>
<groupId>com.heima</groupId>
<artifactId>heima-file-starter</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
- 创建配置文件
minio:
accessKey: minio
secretKey: minio123
bucket: leadnews
endpoint: http://localhost:9000
readPath: http://localhost:9000
- 使用:
@SpringBootTest
class MinIOApplicationTest {
@Autowired
private FileStorageService fileStorageService;
@Test
void test() throws Exception{
FileInputStream fs = null;
fs = new FileInputStream("/tmp/list.html");
String path = fileStorageService.uploadHtmlFile("", "list.html", fs);
System.out.println(path);
}
}
