what is minio
Quoting the official website:
MinIO is a high-performance object storage released under the GNU Affero General Public License v3.0. It is compatible with Amazon S3 cloud storage service. Build high-performance infrastructure for machine learning, analytics, and application data workloads with MinIO.
Official website address:
https://min.io/
Document address:
https://docs.min.io/
1. Use docker to build minio service.
GNU/Linux and 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 /datawindows
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 /dataMINIO_ROOT_USER: is the user keyMINIO_ROOT_PASSWORD: is the user key
The above builds are all standalone versions. To understand the distributed method, please check the official website documentation.
This is what runs on win's docker.
After startup, http://localhost:9000you can access the graphical interface of minio in the browser, as shown in the figure:
2. Let's start to build the springboot environment
Everyone knows how to initialize a springboot project, so I won't introduce it here.
Recommend a Spring Boot basic tutorial and practical example: https://github.com/javastacks/spring-boot-best-practice
It mainly introduces the dependencies that need to be introduced:
<!-- 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>In addition, this Spring Boot study notes are shared with you.
Dependencies can be found in the official documentation:https://docs.min.io/docs/java-client-quickstart-guide.html
The configuration files are described below:
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: falseCreate a configuration class for minio:
@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();
}
}Use configuration property binding for parameter binding, and initialize a minio client object into the container. The latest Spring Boot interview questions have been sorted out, and you can brush the questions online in the Java interview library applet.
The following are the components of the simple way I encapsulated the minio client to operate minio.
@Component
public class MinioComp {
@Autowired
private MinioClient minioClient;
@Autowired
private MinioConfiguration configuration;
/**

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;
