開發(fā)好物推薦7之對象存儲服務(wù)Minio
前言
開發(fā)中,一般都會單獨的分離出一個文件服務(wù)器,存儲對象存儲大容量非結(jié)構(gòu)化的數(shù)據(jù),例如圖片、視頻、日志文件、備份數(shù)據(jù)和容器/虛擬機鏡像等。大部分我們還在用FastDFS,我要吐槽幾句它部署麻煩,也沒有管理界面,所以我推薦另一個對象存儲服務(wù)Minio,肯定讓你眼前一亮,有種相見恨晚的感覺。
推薦理由
- 開源免費(是我們考慮的首要元素),高性能
- 長的好看:有漂亮的界面。
- 為云環(huán)境而生:與k8s、etcd、docker等深度集成。
- 文檔詳細:提供了Java、JavaScript、Python、Golang、.Net等各種語言的sdk,集成變得更加容易
- 部署簡單
docker部署
將MiniIO的數(shù)據(jù)和配置文件夾掛在到宿主機上
- docker run -p 9090:9000 --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;# 如果不創(chuàng)建用戶名密碼,默認用戶名密碼: minioadmin:minioadmin

springboot 使用minio
1 引入maven
- <dependency>
- <groupId>io.minio</groupId>
- <artifactId>minio</artifactId>
- <version>7.0.2</version>
- </dependency>
2 配置 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 注入屬性
- @Component
- @ConfigurationProperties(prefix = "minio")
- public class MinioConfig { // "endPoint是一個URL,域名,IPv4或者IPv6地址"
- private String url; //("accessKey類似于用戶ID,用于唯一標識你的賬戶")
- private String accessKey; //("secretKey是你賬戶的密碼")
- private String secretKey; //("如果是true,則用的是https而不是http,默認值是true")
- private Boolean secure; //("默認存儲桶")
- private String bucketName; //("配置目錄")
- 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 創(chuàng)建工具類
- @Component
- public class MinioUtil {
- @Autowired
- private MinioClient minioClient;
- /**
- * 上傳文件
- */
- 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 測試
- @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 FileInputStream(new File("C:\\Users\\ctyc\\Desktop\\1.jpg")), "test1.jpg");
- minioUtil.downloadFile("test", "test1.jpg", "t1.jpg", response);
- return "Hello " + name + "!";
- }}
