搜索镜像
docker search minio拉取镜像
docker pull minio/minio启动minio
docker run -p 9000:9000 -p 9090:9090 --name minio \-d --restartalways \-e MINIO_ACCESS_KEYvinci \-e MINIO_SECRET_KEY123456\-v /usr/local/minio/data:/data \-v /usr/local/minio/config:/root/.minio \minio/minio server /data --console-address :9000 --address :9090-p: 指定端口映射格式为主机端口:容器端口 (这里注意要映射两个否则API会访问不到) -e “MINIO_ROOT_USERvinci” minio用户名 -e MINIO_SECRET_KEY123456 minio 密码 -d: 后台运行容器并返回容器ID -v: 绑定一个卷 这里可以看到minio已经在docker里启动起来了
接下来我们可以通过以下命令来查看 minio console和minio api 访问端口
docker logs minio访问minio控制台 在此步骤前记得开放端口号 我们接下来可以使用密码和账号登录minio控制台了
3.Spring Boot 整合 minio
在此之前我们可以先通过控制台来创建一个bucket
集成minio
dependencygroupIdio.minio/groupIdartifactIdminio/artifactIdversion8.4.0/version
/dependency编写minio配置类
/*** package: com.vinci.minio.config* className: MinioConfig* author: Vinci* description: minio配置类* date: 2023/10/27 13:10*/
Data
Configuration
ConfigurationProperties(prefix minio)
public class MinioConfig {private String endpoint;private String accessKey;private String secretKey;private String bucketName;Beanpublic MinioClient minioClient(){return MinioClient.builder().endpoint(endpoint).credentials(accessKey, secretKey).build();}}在application.properties中添加以下配置
minio.endpointhttp://108.13.21.28:9090/
minio.bucket-nameimages
minio.access-keyxxxxx
minio.secret-keyxxxxx注意 minio.endpoint 是minio API地址不是控制台地址 minio.bucket-name 是 bucket的名称 minio.access-key 是用户名 minio.secret-key是密码 编写minio工具类

4.测试 minio 文件上传、下载及图片预览等功能
编写controller通过接口的方式来测试minio功能
package com.vinci.minio.controller;import com.vinci.minio.utils.MinioUtil;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.multipart.MultipartFile;import javax.annotation.Resource;
import javax.servlet.http.HttpServletResponse;/*** package: com.vinci.minio.controller* className: TestMinioController* author: Vinci* description: 测试minio* date: 2023/10/27 13:48*/
Controller
RequestMapping(value /minio)
public class TestMinioController {Resourceprivate MinioUtil minioUtil;/*** description: 文件上传测试* author: Vinci* date: 2023/10/27 13:48**/ResponseBodyPostMapping(/upload)public String fileUpload(MultipartFile file) {return minioUtil.upload(file);}/*** description: 文件下载测试* author: Vinci* date: 2023/10/27 13:51**/ResponseBodyGetMapping(/download)public String fileDownload(String fileName, HttpServletResponse response){minioUtil.download(fileName,response);return success;}/*** description: 图片预览* author: Vinci* date: 2023/10/27 13:53**/GetMapping(/preview)public String imagePreview(String fileName){return minioUtil.preview(fileName);}}
测试文件上传 使用postMan来调用文件上传的接口 我们返回控制台可以看到文件已经上传上去了 测试文件下载 我们借助postman工具点击发送并下载可以看到文件下载成功了 图片在线预览 我们同样借助postman工具发送请求我们可以看到返回了图片的在线浏览地址点击即可在线浏览图片 以上便是minio 整合springboot的全部流程了感谢阅读 SpringBoot案例地址https://gitee.com/vinci99/springboot-minio-test.git
