SpringBoot集成Minio文件服务器实现文件上传
作者:互联网
1.本文章用docker启动 首先拉取minio镜像 命令:
docker load -i /home/tools/minio.tar
2.启动minion文件服务器 命令:
docker run -p 9000:9000 -d --name minio -e "MINIO_ACCESS_KEY=admin" -e "MINIO_SECRET_KEY=admin123" -v /opt/services/minio/data:/data -v /opt/services/minio/config:/root/.minio docker.io/minio/minio:RELEASE.2020-10-12T21-53-21Z server /data
3.查看minio是否启动成功 命令:docker ps
4. 登录minio服务器 输入步骤2中设置的用户名 密码:
5.搭建springBoot项目工程 添加maven依赖:
<!-- minio客户端 --> <dependency> <groupId>io.minio</groupId> <artifactId>minio</artifactId> <version>7.1.0</version> </dependency>
6.编写minio工具类:
package com.example; import io.minio.*; import org.springframework.beans.factory.annotation.Value; import org.springframework.stereotype.Component; import org.springframework.web.multipart.MultipartFile; import javax.activation.MimetypesFileTypeMap; import javax.servlet.ServletOutputStream; import javax.servlet.http.HttpServletResponse; import java.io.File; import java.io.FileInputStream; import java.io.InputStream; import java.nio.charset.StandardCharsets; import lombok.extern.slf4j.Slf4j; @Component @Slf4j public class MinioService { @Value("${minio.url}") private String url; @Value("${minio.access-key}") private String accessKey; @Value("${minio.secret-key}") private String secretKey; /** * 初始化连接 * @return * @throws Exception */ public MinioClient getMinioClient(){ return MinioClient.builder().endpoint(url).credentials(accessKey, secretKey).build(); } /** * 根据存储桶的名称判断桶是否存在,不存在就创建 * @param bucketName * @throws Exception */ public void isExistBucketName(String bucketName) throws Exception { boolean isExist = getMinioClient().bucketExists(BucketExistsArgs.builder().bucket(bucketName).build()); if(!isExist) { getMinioClient().makeBucket(MakeBucketArgs.builder().bucket(bucketName).build()); log.info(bucketName+"创建成功"); } } /** * Minio文本地文件上传 * @param filePath 完整路径文件名 * @param fileName 修饰过的文件名 非源文件名 * @return */ public Results localMinioUpload(String filePath, String fileName,String bucketName) { try { //判断存储桶是否存在,不存在则创建 isExistBucketName(bucketName); // minio仓库名 File file = new File(filePath); InputStream is = new FileInputStream(file); String contentType = new MimetypesFileTypeMap().getContentType(file); System.out.println(contentType); getMinioClient().putObject( PutObjectArgs.builder() .bucket(bucketName) .object(fileName) .stream(is, file.length(), -1) .contentType(contentType) .build()); log.info("成功上传文件 " + fileName + " 至 " + bucketName); return Results.success(System.currentTimeMillis()); } catch (Exception e) { e.printStackTrace(); return Results.requestFailMsg(System.currentTimeMillis(),"上传存储服务器出错异常"); } } /** * Minio远程文件上传 上传对象是MultipartFile * @param file 文件实体 * @param fileName 修饰过的文件名 非源文件名 * @return */ public Results minioUpload(MultipartFile file, String fileName, String bucketName) { try { //判断存储桶是否存在,不存在则创建 isExistBucketName(bucketName); // fileName为空,说明要使用源文件名上传 if (fileName == null) { fileName = file.getOriginalFilename(); fileName = fileName.replaceAll(" ", "_"); } getMinioClient().putObject( PutObjectArgs.builder() .bucket(bucketName) .object(fileName) .stream(file.getInputStream(), file.getSize(), -1) .contentType(file.getContentType()) .build()); log.info("成功上传文件 " + fileName + " 至 " + bucketName); // String fileUrl = bucketName + "/" + fileName; // Map<String, Object> map = new HashMap<String, Object>(); // map.put("fileUrl", fileUrl); // map.put("bucketName", bucketName); // map.put("originFileName", fileName); return Results.success(System.currentTimeMillis()); } catch (Exception e) { e.printStackTrace(); return Results.requestFailMsg(System.currentTimeMillis(),"上传存储服务器出错异常"); } } /** * 判断文件是否存在 * @param fileName 文件全路径 * @param bucketName 存储桶名称 * @return */ public boolean isFileExisted(String fileName,String bucketName) { InputStream inputStream = null; try { inputStream = getMinioClient().getObject( GetObjectArgs.builder() .bucket(bucketName) .object(fileName) .build()); if (inputStream != null) { return true; } } catch (Exception e) { return false; } finally { if (inputStream != null) { try { inputStream.close(); } catch (Exception e) { e.printStackTrace(); } } } return false; } /** * 删除文件 * @param bucketName 桶名(文件夹) * @param fileName 文件名 * @return */ public boolean delete(String bucketName,String fileName) { try { getMinioClient().removeObject( RemoveObjectArgs.builder().bucket(bucketName).object(fileName).build()); return true; } catch (Exception e) { log.error(e.getMessage()); return false; } } /** * 获取文件的外链访问URL,并设置URL访问有效期 * @param fileName * @return * @throws Exception */ public String getShowUtrl (String fileName,int expires,String bucketName) throws Exception{ String tempUrl = getMinioClient().presignedGetObject(bucketName, fileName, expires); return tempUrl; } /** * 下载文件 * @param objectName 文件名 * @param response * @return */ public Results downloadFile(String objectName, HttpServletResponse response, String bucketName) { try { InputStream stream = getMinioClient().getObject(GetObjectArgs.builder().bucket(bucketName).object(objectName).build()); String filename = new String(objectName.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=stream.read(buffer)) > 0){ servletOutputStream.write(buffer, 0, len); } servletOutputStream.flush(); stream.close(); servletOutputStream.close(); return Results.success(System.currentTimeMillis()); } catch (Exception e) { e.printStackTrace(); return Results.requestFailMsg(System.currentTimeMillis(),"下载报错异常!"); } } public static void main(String[] args) throws Exception { MinioService ms = new MinioService(); String strUrl = "D:/photo/1.jpg"; ms.localMinioUpload(strUrl,"D:/photo/1.jpg","test"); } } 7.编写测试TestController层
/** * @author 何志鹏 * @version 1.0 * @date 2021/10/28 17:08 */ @RestController @RequestMapping("/minio") public class TestController { @Value("${minio.bucket-name}") private String bucketName; @Autowired private MinioService minioService; @PostMapping("/minioUpload") public Results minioUpload(MultipartFile file){ String fileName = file.getOriginalFilename(); return minioService.minioUpload(file, fileName, bucketName); } }
8.通过postman进行文件上传测试
9.然后去minio文件服务器上查看刚才上传的文件
10.最后附上码云gitee地址:https://gitee.com/hezhipeng_ek/minio.git 项目中有minio的docker镜像
