一、使用docker部署minio
1、拉取镜像
docker pull minio/minio2、创建目录
mkdir -p /home/minio/configmkdir -p /home/minio/data3、创建Minio容器并运行
docker run -p 9000:9000 -p 9090:9090 \ --net=host \ --name minio \ -d --restart=always \ -e "MINIO_ACCESS_KEY=minioadmin" \ -e "MINIO_SECRET_KEY=minioadmin" \ -v /home/minio/data:/data \ -v /home/minio/config:/root/.minio \ minio/minio server \ /data --console-address ":9090" -address ":9000"
4、登录minio控制台
5、创建buckets存储桶测试
创建一个名为public的存储桶（名字可自定义），上传文件。
通过http://ip:9000/存储桶名/文件名访问文件
若出现：
可以将存储桶的访问权限设置为public.
二、SpringBoot整合minio
1、创建minio-demo项目
2、引入pom依赖
io.minio minio 7.0.2 3、编写配置文件
在application.yml文件中编写相关配置。
server: port: 8081spring: # 配置文件上传大小限制 servlet: multipart: max-file-size: 200MB max-request-size: 200MBminio: host: http://127.0.0.1:9000 url: ${minio.host}/${minio.bucket}/ access-key: minioadmin secret-key: minioadmin bucket: public4、编写MinioConfig配置类
import io.minio.MinioClient;import io.minio.ObjectStat;import io.minio.PutObjectOptions;import io.minio.Result;import io.minio.messages.Bucket;import io.minio.messages.Item;import org.apache.tomcat.util.http.fileupload.IOUtils;import org.springframework.beans.factory.InitializingBean;import org.springframework.beans.factory.annotation.Value;import org.springframework.stereotype.Component;import org.springframework.util.Assert;import org.springframework.web.multipart.MultipartFile;import org.springframework.web.util.UriUtils;import javax.servlet.http.HttpServletResponse;import java.io.IOException;import java.io.InputStream;import java.net.URLEncoder;import java.nio.charset.StandardCharsets;import java.util.ArrayList;import java.util.List;@Componentpublic class MinioConfig implements InitializingBean { @Value(value = "${minio.bucket}") private String bucket; @Value(value = "${minio.host}") private String host; @Value(value = "${minio.url}") private String url; @Value(value = "${minio.access-key}") private String accessKey; @Value(value = "${minio.secret-key}") private String secretKey; private MinioClient minioClient; @Override public void afterPropertiesSet() throws Exception { Assert.hasText(url, "Minio url 为空"); Assert.hasText(accessKey, "Minio accessKey为空"); Assert.hasText(secretKey, "Minio secretKey为空"); this.minioClient = new MinioClient(this.host, this.accessKey, this.secretKey); } public String putObject(MultipartFile multipartFile) throws Exception { // bucket 不存在，创建 if (!minioClient.bucketExists(this.bucket)) { minioClient.makeBucket(this.bucket); } try (InputStream inputStream = multipartFile.getInputStream()) { // 上传文件的名称 String fileName = multipartFile.getOriginalFilename(); // PutObjectOptions，上传配置(文件大小，内存中文件分片大小) PutObjectOptions putObjectOptions = new PutObjectOptions(multipartFile.getSize(), PutObjectOptions.MIN_MULTIPART_SIZE); // 文件的ContentType putObjectOptions.setContentType(multipartFile.getContentType()); minioClient.putObject(this.bucket, fileName, inputStream, putObjectOptions); // 返回访问路径 return this.url + UriUtils.encode(fileName, StandardCharsets.UTF_8); } } public void download(String fileName, HttpServletResponse response){ // 从链接中得到文件名 InputStream inputStream; try { MinioClient minioClient = new MinioClient(host, accessKey, secretKey); ObjectStat stat = minioClient.statObject(bucket, fileName); inputStream = minioClient.getObject(bucket, fileName); response.setContentType(stat.contentType()); response.setCharacterEncoding("UTF-8"); response.setHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode(fileName, "UTF-8")); IOUtils.copy(inputStream, response.getOutputStream()); inputStream.close(); } catch (Exception e){ e.printStackTrace(); System.out.println("有异常：" + e); } } public List listBucketNames() throws Exception { List bucketList = listBuckets(); List bucketListName = new ArrayList<>(); for (Bucket bucket : bucketList) { bucketListName.add(bucket.name()); } return bucketListName; } public List listBuckets() throws Exception { return minioClient.listBuckets(); } public boolean bucketExists(String bucketName) throws Exception { boolean flag = minioClient.bucketExists(bucketName); if (flag) { return true; } return false; } public boolean makeBucket(String bucketName) throws Exception { boolean flag = bucketExists(bucketName); if (!flag) { minioClient.makeBucket(bucketName); return true; } else { return false; } } public boolean removeBucket(String bucketName) throws Exception { boolean flag = bucketExists(bucketName); if (flag) { Iterable> myObjects = listObjects(bucketName); for (Result- result : myObjects) { Item item = result.get(); // 有对象文件，则删除失败 if (item.size() > 0) { return false; } } // 删除存储桶，注意，只有存储桶为空时才能删除成功。 minioClient.removeBucket(bucketName); flag = bucketExists(bucketName); if (!flag) { return true; } } return false; } public Iterable
> listObjects(String bucketName) throws Exception { boolean flag = bucketExists(bucketName); if (flag) { return minioClient.listObjects(bucketName); } return null; } public List listObjectNames(String bucketName) throws Exception { List listObjectNames = new ArrayList<>(); boolean flag = bucketExists(bucketName); if (flag) { Iterable> myObjects = listObjects(bucketName); for (Result- result : myObjects) { Item item = result.get(); listObjectNames.add(item.objectName()); } } return listObjectNames; } public boolean removeObject(String bucketName, String objectName) throws Exception { boolean flag = bucketExists(bucketName); if (flag) { List
objectList = listObjectNames(bucketName); for (String s : objectList) { if(s.equals(objectName)){ minioClient.removeObject(bucketName, objectName); return true; } } } return false; } public String getObjectUrl(String bucketName, String objectName) throws Exception { boolean flag = bucketExists(bucketName); String url = ""; if (flag) { url = minioClient.getObjectUrl(bucketName, objectName); } return url; }} 5、编写MinioController类
import com.minio.demo.config.MinioConfig;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.*;import org.springframework.web.multipart.MultipartFile;import javax.servlet.http.HttpServletResponse;import java.util.List;@RestController@CrossOrigin@RequestMapping("/test")public class MinioController { @Autowired MinioConfig minioConfig; // 上传 @PostMapping("/upload") public Object upload(@RequestParam("file") MultipartFile multipartFile) throws Exception { return this.minioConfig.putObject(multipartFile); } // 下载文件 @GetMapping("/download") public void download(@RequestParam("fileName")String fileName, HttpServletResponse response) { this.minioConfig.download(fileName,response); } // 列出所有存储桶名称 @PostMapping("/list") public List list() throws Exception { return this.minioConfig.listBucketNames(); } // 创建存储桶 @PostMapping("/createBucket") public boolean createBucket(String bucketName) throws Exception { return this.minioConfig.makeBucket(bucketName); } // 删除存储桶 @PostMapping("/deleteBucket") public boolean deleteBucket(String bucketName) throws Exception { return this.minioConfig.removeBucket(bucketName); } // 列出存储桶中的所有对象名称 @PostMapping("/listObjectNames") public List listObjectNames(String bucketName) throws Exception { return this.minioConfig.listObjectNames(bucketName); } // 删除一个对象 @PostMapping("/removeObject") public boolean removeObject(String bucketName, String objectName) throws Exception { return this.minioConfig.removeObject(bucketName, objectName); } // 文件访问路径 @PostMapping("/getObjectUrl") public String getObjectUrl(String bucketName, String objectName) throws Exception { return this.minioConfig.getObjectUrl(bucketName, objectName); }} 6、测试（上传）
开发中上传接口用得较多，其他接口可自行测试。
三、Vue+Element-ui前端交互
# npm下载element-ui
npm install element-ui -S
// 引入ElementUIimport ElementUI from 'element-ui'import 'element-ui/lib/theme-chalk/index.css'Vue.use(ElementUI)
![]()
