推荐理由
开源免费(是我们考虑的首要元素),高性能
长的好看:有漂亮的界面。
为云环境而生:与k8s、etcd、docker等深度集成。
文档详细:提供了Java、JavaScript、Python、Golang、.Net等各种语言的sdk,集成变得更加容易
部署简单
docker部署
将MiniIO的数据和配置文件夹挂在到宿主机上
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;# 如果不创建用户名密码,默认用户名密码: minioadmin:minioadmin
访问
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 注入属性
@Component @ConfigurationProperties(prefix = "minio") public class MinioConfig { // "endPoint是一个URL,域名,IPv4或者IPv6地址" private String url; //("accessKey类似于用户ID,用于唯一标识你的账户") private String accessKey; //("secretKey是你账户的密码") private String secretKey; //("如果是true,则用的是https而不是http,默认值是true") private Boolean secure; //("默认存储桶") private String bucketName; //("配置目录") 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 创建工具类
@Component public class MinioUtil { @Autowired private MinioClient minioClient; 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 测试
@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 + "!"; }}
