minio安装配置教程及整合springboot
1、进入minio官网
https://www.minio.org.cn/
点击下载(Download),选择自己需要的版本即可
2、选择放置minio文件路径
在此路径下,
新建文件夹minioData(与minio.exe处于同一路径)
在minio.exe文件夹的路径处输入cmd进入命令行界面(该exe文件不能双击运行)
输入命令:minio.exe server minioData全路径
例如:minio.exe server E:\software\minioData
后面路径为创建的minioData文件夹的路径
(如果上面命令执行的时候,命令框在疯狂跳动,就关闭该命令框,以管理员方式开启cmd窗口,进入自己的minio文件夹,执行上面的命令即可)
3、根据命令行提示访问minio面板
有多个url可以访问,但是其中固定的是127.0.0.1:9000
第一次访问,会进入登录页面,登录账户和密码均为minioadmin,
进入点击Create Bucket,bucket Name 建议设定为项目的名字,再点击Create Bucket即可,注意如果需要后期通过访问url预览,需要在新建的bucket Name点击Manage,点击AccessPolicy后面的icon(图标),将访问权限改为Public即可,在项目运行中必须开启minio服务,否则无法使用minion。
4、minio配置(yaml文件版)
spring: # 配置文件上传大小限制(minio文件上传) servlet: multipart: max-file-size: 200MB max-request-size: 200MBminio: endpoint: http://127.0.0.1:9000 accessKey: minioadmin secretKey: minioadmin bucketName: community-web
如果前面有spring配置,只需要将spring的配置minio文件限制复制贴贴到spring下即可。
5、编写minio的配置文件MinIoClientConfig
package com.example.config;import io.minio.MinioClient;import lombok.Data;import org.springframework.beans.factory.annotation.Value;import org.springframework.context.annotation.Bean;import org.springframework.stereotype.Component;@Data@Componentpublic class MinIoClientConfig { @Value("${minio.endpoint}") private String endpoint; @Value("${minio.accessKey}") private String accessKey; @Value("${minio.secretKey}") private String secretKey; @Bean public MinioClient minioClient() { return MinioClient.builder() .endpoint(endpoint) .credentials(accessKey, secretKey) .build(); }}
6、新建minio工具类需要的实体类ObjectItem
package com.example.sys.entity;import lombok.Data;@Datapublic class ObjectItem { private String objectName; private Long size;}
7、编写minio的工具类MinioUtils
package com.example.utils;import com.example.sys.entity.ObjectItem;import io.minio.*;import io.minio.messages.DeleteError;import io.minio.messages.DeleteObject;import io.minio.messages.Item;import org.apache.tomcat.util.http.fileupload.IOUtils;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Value;import org.springframework.http.HttpHeaders;import org.springframework.http.HttpStatus;import org.springframework.http.MediaType;import org.springframework.http.ResponseEntity;import org.springframework.stereotype.Component;import org.springframework.web.multipart.MultipartFile;import java.io.ByteArrayOutputStream;import java.io.IOException;import java.io.InputStream;import java.io.UnsupportedEncodingException;import java.net.URLEncoder;import java.util.ArrayList;import java.util.Arrays;import java.util.List;import java.util.stream.Collectors;@Componentpublic class MinioUtils { @Autowired private MinioClient minioClient; @Value("${minio.bucketName}") private String bucketName; public void existBucket(String name) { try { boolean exists = minioClient.bucketExists(BucketExistsArgs.builder().bucket(name).build()); if (!exists) { minioClient.makeBucket(MakeBucketArgs.builder().bucket(name).build()); } } catch (Exception e) { e.printStackTrace(); } } public Boolean makeBucket(String bucketName) { try { minioClient.makeBucket(MakeBucketArgs.builder() .bucket(bucketName) .build()); } catch (Exception e) { e.printStackTrace(); return false; } return true; } public Boolean removeBucket(String bucketName) { try { minioClient.removeBucket(RemoveBucketArgs.builder() .bucket(bucketName) .build()); } catch (Exception e) { e.printStackTrace(); return false; } return true; } public List upload(MultipartFile[] multipartFile) { List names = new ArrayList<>(multipartFile.length); for (MultipartFile file : multipartFile) { String fileName = file.getOriginalFilename(); String[] split = fileName.split("\\."); if (split.length > 1) { fileName = split[0] + "_" + System.currentTimeMillis() + "." + split[1]; } else { fileName = fileName + System.currentTimeMillis(); } InputStream in = null; try { in = file.getInputStream(); minioClient.putObject(PutObjectArgs.builder() .bucket(bucketName) .object(fileName) .stream(in, in.available(), -1) .contentType(file.getContentType()) .build() ); } catch (Exception e) { e.printStackTrace(); } finally { if (in != null) { try { in.close(); } catch (IOException e) { e.printStackTrace(); } } } names.add(fileName); } return names; } public ResponseEntity download(String fileName) { ResponseEntity responseEntity = null; InputStream in = null; ByteArrayOutputStream out = null; try { in = minioClient.getObject(GetObjectArgs.builder().bucket(bucketName).object(fileName).build()); out = new ByteArrayOutputStream(); IOUtils.copy(in, out); //封装返回值 byte[] bytes = out.toByteArray(); HttpHeaders headers = new HttpHeaders(); try { headers.add("Content-Disposition", "attachment;filename=" + URLEncoder.encode(fileName, "UTF-8")); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } headers.setContentLength(bytes.length); headers.setContentType(MediaType.APPLICATION_OCTET_STREAM); headers.setAccessControlExposeHeaders(Arrays.asList("*")); responseEntity = new ResponseEntity(bytes, headers, HttpStatus.OK); } catch (Exception e) { e.printStackTrace(); } finally { try { if (in != null) { try { in.close(); } catch (IOException e) { e.printStackTrace(); } } if (out != null) { out.close(); } } catch (IOException e) { e.printStackTrace(); } } return responseEntity; } public List listObjects(String bucketName) { Iterable> results = minioClient.listObjects( ListObjectsArgs.builder().bucket(bucketName).build()); List objectItems = new ArrayList<>(); try { for (Result- result : results) { Item item = result.get(); ObjectItem objectItem = new ObjectItem(); objectItem.setObjectName(item.objectName()); objectItem.setSize(item.size()); objectItems.add(objectItem); } } catch (Exception e) { e.printStackTrace(); return null; } return objectItems; } public Iterable
> removeObjects(String bucketName, List objects) { List dos = objects.stream().map(e -> new DeleteObject(e)).collect(Collectors.toList()); Iterable> results = minioClient.removeObjects(RemoveObjectsArgs.builder().bucket(bucketName).objects(dos).build()); return results; }}
8、编写minio的Controller层MinioController
package com.example.sys.controller;import com.example.utils.MinioUtils;import lombok.extern.slf4j.Slf4j;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Value;import org.springframework.web.bind.annotation.PostMapping;import org.springframework.web.bind.annotation.RestController;import org.springframework.web.multipart.MultipartFile;import java.util.List;@RestController@Slf4jpublic class MinioController { @Autowired private MinioUtils minioUtils; @Value("${minio.endpoint}") private String address; @Value("${minio.bucketName}") private String bucketName; @PostMapping("/upload") public Object upload(MultipartFile file) { List upload = minioUtils.upload(new MultipartFile[]{file}); return address + "/" + bucketName + "/" + upload.get(0); }}
9.通过接口测试工具测试
1)新建一个请求(Request)
2)请求方式修改为post
3)请求的url,项目访问路径/upload
例如:http://127.0.0.1:8080/upload
4)选择Body
5)选择Form-Data
6)填写key和value
第一个键值
key—>file
参数类型为file
value—>点击Select Files按钮,选择文件(建议图片)
第二个键值
key—>bucketName
参数类型:选择String
value—>个人设置的桶(bucketName)的名称
最后点击send,发送即可
通过响应的url,复制到浏览器,打开即可,一般打开即可预览到图片,有些电脑会直接下载图片。
