SpringBoot + minio实现分片上传、秒传、续传功能
作者:TNT报社
什么是minio
MinIO是一个基于Go实现的高性能、兼容S3协议的对象存储。它采用GNU AGPL v3开源协议,项目地址是https://github.com/minio/minio。
引用官网:
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:

一. 使用docker 搭建minio 服务
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
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:
二. 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,公众 号Java精选 * @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 (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(); } return null; } /** * @description: 获取上传文件的url,公众 号Java精选,有惊喜! * @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) { 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 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。)
下面展示页面html,使用的是VUE+element-ui进行渲染。
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <!-- import CSS --> <link rel="stylesheet" href="https://unpkg.com/element-ui/lib/theme-chalk/index.css" rel="external nofollow" > <title>上传图片</title> </head> <body> <div id="app"> <el-row :gutter="2"> <el-col :span="8"> <div class="div-center-class"> <div class=""> <center><h3>传统上传</h3></center> <el-upload class="upload-demo" action="#" drag :http-request="uploadHandle"> <i class="el-icon-upload"></i> <div class="el-upload__text">将文件拖到此处,或<em>点击上传</em></div> <div class="el-upload__tip" slot="tip">只能上传jpg/png文件,且不超过500kb</div> </el-upload> <div v-if="imgUrl"> <img :src="imgUrl" style="width: 40px;height: 40px"></img> </div> </div> </div> </el-col> <el-col :span="8"> <div class="div-center-class"> <div class=""> <center><h3>前端formData直传</h3></center> <el-upload class="upload-demo" action="#" drag :http-request="httpRequestHandle"> <i class="el-icon-upload"></i> <div class="el-upload__text">将文件拖到此处,或<em>点击上传</em></div> <div class="el-upload__tip" slot="tip">只能上传jpg/png文件,且不超过500kb</div> </el-upload> <div v-if="directUrl"> <img :src="directUrl" style="width: 40px;height: 40px"></img> </div> </div> </div> </el-col> <el-col :span="8"> <div class="div-center-class"> <div class=""> <center><h3>前端Url直传</h3></center> <el-upload class="upload-demo" action="#" drag :http-request="UrlUploadHandle"> <i class="el-icon-upload"></i> <div class="el-upload__text">将文件拖到此处,或<em>点击上传</em></div> <div class="el-upload__tip" slot="tip">只能上传jpg/png文件,且不超过500kb</div> </el-upload> <div v-if="uploadUrl"> <img :src="uploadUrl" style="width: 40px;height: 40px"></img> </div> </div> </div> </el-col> </el-row> </div> </body> <!-- import Vue before Element --> <script src="https://unpkg.com/vue/dist/vue.js"></script> <!-- import JavaScript --> <script src="https://unpkg.com/element-ui/lib/index.js"></script> <!--import axios --> <script src="https://unpkg.com/axios/dist/axios.min.js"></script> <script> new Vue({ el: '#app', data: function () { return { imgUrl: '', directUrl: '', uploadUrl: '' } }, methods: { uploadHandle(options) { let {file} = options; this.traditionPost(file); }, traditionPost(file) { _that = this const form = new FormData(); form.append("fileName", file.name); form.append("file", file); this.axiosPost("post", "/upload", form).then(function (res) { if (res.status === 200) { _that.imgUrl = res.data.data } else { alert("上传失败!") } }) }, getpolicy(file) { _that = this axios.get('policy?fileName=' + file.name) .then(function (response) { let {xamzalgorithm, xamzcredential, policy, xamzsignature, xamzdate, host} = response.data.data; let formData = new FormData(); formData.append("key", file.name); formData.append("x-amz-algorithm", xamzalgorithm); // 让服务端返回200,不设置则默认返回204。 formData.append("x-amz-credential", xamzcredential); formData.append("policy", policy); formData.append("x-amz-signature", xamzsignature); formData.append("x-amz-date", xamzdate); formData.append("file", file); // 发送 POST 请求 _that.axiosPost("post", host, formData).then(function (res) { if (res.status === 204) { axios.get('url?fileName=' + file.name).then(function (res) { _that.directUrl = res.data.data; }) } else { alert("上传失败!") } }) }) }, httpRequestHandle(options) { let {file} = options; this.getpolicy(file); }, UrlUploadHandle(options) { let {file} = options; this.getUploadUrl(file); }, getUploadUrl(file) { _that = this console.log(file) axios.get('uploadUrl?fileName=' + file.name) .then(function (response) { let url = response.data.data; // 发送 put 请求 let config = {'Content-Type': file.type} _that.axiosPost("put", url, file, config).then(function (res) { if (res.status === 200) { axios.get('url?fileName=' + file.name).then(function (res) { _that.uploadUrl = res.data.data; }) } else { alert("上传失败!") } }) }) }, //封装 //axios封装post请求 axiosPost(method, url, data, config) { let result = axios({ method: method, url: url, data: data, headers: config }).then(resp => { return resp }).catch(error => { return "exception=" + error; }); return result; } } }) </script> <style> .div-center-class { padding: 28% 0%; text-align: center; background: beige; } </style> </html>
页面的效果就如上图所示。
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。
