Docker deployment

Hang the MiniIO data and configuration folders on the host computer

Docker run-p 9090 MINIO_ACCESS_KEY=admin 9000-- name minio\-e MINIO_ACCESS_KEY=admin-e MINIO_SECRET_KEY=123123123\-v / mydata/minio/data:/data\-v / mydata/minio/config:/root/.minio\-d minio/minio server / data;# if you do not create a username password, the default username password is minioadmin:minioadmin

Visit

Springboot uses minio

1 introduction of maven

Io.minio minio 7.0.2

2 configure application.properties

Minio.url= http://192.168.3.189:9090 minio.accessKey= adminminio.secretKey= 123123123 minio.secure=false minio.bucketName=testminio.configDir=/home/data/

3 injection attribute

@ Component @ ConfigurationProperties (prefix = "minio") public class MinioConfig {/ / "endPoint is a URL, domain name, IPv4 or IPv6 address" private String url; / / ("accessKey is similar to user ID and is used to uniquely identify your account") private String accessKey; / / ("secretKey is your account password") private String secretKey; / / ("if true, use https instead of http, default is true") private Boolean secure / / ("default bucket") private String bucketName; / / ("configuration directory") private String configDir; @ Bean public MinioClient getMinioClient () throws InvalidEndpointException, InvalidPortException {MinioClient minioClient = new MinioClient (url, accessKey, secretKey,secure); return minioClient;} public String getBucketName () {return bucketName;} public String getConfigDir () {return configDir;} public String getUrl () {return url } public void setUrl (String url) {this.url = url;} public String getAccessKey () {return accessKey;} public void setAccessKey (String accessKey) {this.accessKey = accessKey;} public String getSecretKey () {return secretKey;} public void setSecretKey (String secretKey) {this.secretKey = secretKey;} public Boolean getSecure () {return secure } public void setSecure (Boolean secure) {this.secure = secure;} public void setBucketName (String bucketName) {this.bucketName = bucketName;} public void setConfigDir (String configDir) {this.configDir = configDir;}}

4 create a tool class

@ Component public class MinioUtil {@ Autowired private MinioClient minioClient; / * upload File * / public void uploadFile (InputStream inputStream, String objectName) {String buckName = "test"; try {if (! minioClient.bucketExists (buckName)) {minioClient.makeBucket (buckName) } minioClient.putObject (buckName, objectName, inputStream, inputStream.available (), "image/jpeg");} catch (Exception e) {e.printStackTrace ();}} public void downloadFile (String bucketName, String fileName, String originalName, HttpServletResponse response) {try {InputStream file = minioClient.getObject (bucketName, fileName) String filename= new String (fileName.getBytes ("ISO8859-1"), StandardCharsets.UTF_8); response.setHeader ("Content-Disposition", "attachment;filename=" + filename); ServletOutputStream servletOutputStream = response.getOutputStream (); int len; byte [] buffer = new byte [1024] While ((len = file.read (buffer)) > 0) {servletOutputStream.write (buffer, 0, len);} servletOutputStream.flush (); file.close (); servletOutputStream.close ();} catch (ErrorResponseException e) {e.printStackTrace () } catch (Exception e) {e.printStackTrace ();}

5 Test

@ RestController public class GreetingsController {@ Autowired MinioUtil minioUtil; @ RequestMapping (value = "/ {name}", method = RequestMethod.GET) @ ResponseStatus (HttpStatus.OK) public String greetingText (@ PathVariable String name,HttpServletResponse response) throws FileNotFoundException {minioUtil.uploadFile (new File ("C:\ Users\\ ctyc\\ Desktop\ 1.jpg"), "test1.jpg") MinioUtil.downloadFile ("test", "test1.jpg", "t1.jpg", response); return "Hello" + name + "!";}} at this point, the study on "how to use the object storage service Minio" is over, hoping to solve everyone's doubts.
