SpringBoot 高性能存储服务
JimmyThomas 人气:01.什么是MinIO
MinIO是根据GNU Affero通用公共许可证v3.0发布的高性能对象存储。它与Amazon S3云存储服务兼容。使用MinIO构建用于机器学习，分析和应用程序数据工作负载的高性能基础架构。
官网地址：https://min.io/
文档地址：https://docs.min.io/
2.使用docker 搭建minio 服务
2.1.GNU / Linux和macOS
docker run -p 9000:9000 \ --name minio1 \ -v /mnt/data:/data \ -e "MINIO_ROOT_USER=AKIAIOSFODNN7EXAMPLE" \ -e "MINIO_ROOT_PASSWORD=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY" \ minio/minio server /data
2.2.windows
docker run -p 9000:9000 \ --name minio1 \ -v D:\data:/data \ -e "MINIO_ROOT_USER=AKIAIOSFODNN7EXAMPLE" \ -e "MINIO_ROOT_PASSWORD=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY" \ minio/minio server /data
MINIO_ROOT_USER：为用户keyMINIO_ROOT_PASSWORD：为用户密钥
以上搭建的都是单机版的。想要了解分布式 的方式请查看官网文档。
这就是在win的docker上运行的。
当启动后在浏览器访问 http://localhost:9000 就可以访问minio的图形化界面了，如图所示：
3.下面开始搭建springboot 环境
初始化一个springboot项目大家都会，这里不多做介绍。
主要是介绍需要引入的依赖：
<!-- thymeleaf模板渲染引擎-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<!-- 操作minio的java客户端-->
<dependency>
<groupId>io.minio</groupId>
<artifactId>minio</artifactId>
<version>8.2.1</version>
</dependency>
<!-- lombok插件-->
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<optional>true</optional>
</dependency>依赖可以官方文档里找：https://docs.min.io/docs/java-client-quickstart-guide.html
下面介绍配置文件：
spring:
servlet:
multipart:
max-file-size: 10MB
max-request-size: 10MB
#minio配置
minio:
access-key: AKIAIOSFODNN7EXAMPLE #key就是docker初始化是设置的，密钥相同
secret-key: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
url: http://localhost:9000
bucket-name: wdhcr
thymeleaf:
cache: false创建minio的配置类:
@Configuration
@ConfigurationProperties(prefix = "spring.minio")
@Data
public class MinioConfiguration {
private String accessKey;
private String secretKey;
private String url;
private String bucketName;
@Bean
public MinioClient minioClient() {
return MinioClient.builder()
.endpoint(url)
.credentials(accessKey, secretKey)
.build();
}
}使用配置属性绑定进行参数绑定,并初始化一个minio client对象放入容器中。
下面就是我封装的minio client 操作minio的简单方法的组件。
@Component
public class MinioComp {
@Autowired
private MinioClient minioClient;
@Autowired
private MinioConfiguration configuration;
/**
* @description: 获取上传临时签名
* @dateTime: 2021/5/13 14:12
*/
public Map getPolicy(String fileName, ZonedDateTime time) {
PostPolicy postPolicy = new PostPolicy(configuration.getBucketName(), time);
postPolicy.addEqualsCondition("key", fileName);
try {
Map<String, String> map = minioClient.getPresignedPostFormData(postPolicy);
HashMap<String, String> map1 = new HashMap<>();
map.forEach((k,v)->{
map1.put(k.replaceAll("-",""),v);
});
map1.put("host",configuration.getUrl()+"/"+configuration.getBucketName());
return map1;
} catch (ErrorResponseException e) {
e.printStackTrace();

} catch (InternalException e) {

} catch (InvalidKeyException e) {

} catch (InvalidResponseException e) {

} catch (IOException e) {
e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (ServerException e) {
e.printStackTrace();
} catch (XmlParserException e) {
e.printStackTrace();
}
return null;
}
/**
* @description: 获取上传文件的url
* @dateTime: 2021/5/13 14:15
*/
public String getPolicyUrl(String objectName, Method method, int time, TimeUnit timeUnit) {
try {
return minioClient.getPresignedObjectUrl(GetPresignedObjectUrlArgs.builder()
.method(method)
.bucket(configuration.getBucketName())
.object(objectName)
.expiry(time, timeUnit).build());
} catch (ErrorResponseException e) {

} catch (InvalidKeyException e) {

} catch (InvalidResponseException e) {

} catch (IOException e) {
e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (XmlParserException e) {
e.printStackTrace();
} catch (ServerException e) {
e.printStackTrace();
}
return null;
}
/**
* @description: 上传文件
* @dateTime: 2021/5/13 14:17
*/
public void upload(MultipartFile file, String fileName) {
// 使用putObject上传一个文件到存储桶中。
try {
InputStream inputStream = file.getInputStream();
minioClient.putObject(PutObjectArgs.builder()
.bucket(configuration.getBucketName())
.object(fileName)
.stream(inputStream, file.getSize(), -1)
.contentType(file.getContentType())
.build());
} catch (ErrorResponseException e) {
e.printStackTrace();
} catch (InsufficientDataException e) {
e.printStackTrace();
} catch (InternalException e) {
e.printStackTrace();
} catch (InvalidKeyException e) {
e.printStackTrace();
} catch (InvalidResponseException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (ServerException e) {
e.printStackTrace();
} catch (XmlParserException e) {
e.printStackTrace();
}
}
/**
* @description: 根据filename获取文件访问地址
* @dateTime: 2021/5/17 11:28
*/
public String getUrl(String objectName, int time, TimeUnit timeUnit) {
String url = null;
try {
url = minioClient.getPresignedObjectUrl(GetPresignedObjectUrlArgs.builder()
.method(Method.GET)
.bucket(configuration.getBucketName())
.object(objectName)
.expiry(time, timeUnit).build());
} catch (ErrorResponseException e) {
e.printStackTrace();
} catch (InsufficientDataException e) {
e.printStackTrace();
} catch (InternalException e) {
e.printStackTrace();
} catch (InvalidKeyException e) {
e.printStackTrace();
} catch (InvalidResponseException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (XmlParserException e) {
e.printStackTrace();
} catch (ServerException e) {
e.printStackTrace();
}
return url;
}
}简单说明：
- 使用MultipartFile接收前端文件流，再上传到minio。
- 构建一个formData的签名数据，给前端，让前端之前上传到minio。
- 构建一个可以上传的临时URL给前端，前端通过携带文件请求该URL进行上传。
- 使用filename请求服务端获取临时访问文件的URL。（最长时间为7 天，想要永久性访问，需要其他设置，这里不做说明。）

可以分别体验不同的实现效果。
以上就是使用springboot搭建基于minio的高性能存储服务的全部步骤了。
