记录minio 文件上传
MinIO提供多个语言版本SDK的支持，下边找到java版本的文档：
地址：https://docs.min.io/docs/java-client-quickstart-guide.html
maven依赖如下：
XML
<dependency><groupId>io.minio</groupId><artifactId>minio</artifactId><version>8.4.3</version>
</dependency>
<dependency><groupId>com.squareup.okhttp3</groupId><artifactId>okhttp</artifactId><version>4.8.1</version>
</dependency>
需要三个参数才能连接到minio服务。
参数 说明
Endpoint 对象存储服务的URL
Access Key Access key 就像用户ID，可以唯一标识你的账户。
Secret Key Secret key 是你账户的密码。
1.上传
1.1 配置注入
package com.zhan.Config;import io.minio.MinioClient;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;/*** minio 配置注入*/@Data
@ConfigurationProperties(prefix = "minio")
@Configuration
public class MinioConfiguration {private String endpoint;private String accessKey;private String secretKey;private String bucketName;@Beanpublic MinioClient minioClient() {return MinioClient.builder().endpoint(endpoint).credentials(accessKey, secretKey).build();}
}
1.2 上传一个文件
/*** 上传一个文件* @param stream* @param bucket* @param objectName // 文件名* @throws Exception*/public void uploadFile(InputStream stream, String bucket, String objectName) throws Exception {minioClient.putObject(PutObjectArgs.builder().bucket(bucket).object(objectName).stream(stream, -1, 10485760).build());}
@Testpublic void upload() {//根据扩展名取出mimeTypeContentInfo extensionMatch = ContentInfoUtil.findExtensionMatch(".mp4");String mimeType = MediaType.APPLICATION_OCTET_STREAM_VALUE;//通用mimeType，字节流if(extensionMatch!=null){mimeType = extensionMatch.getMimeType();}try {UploadObjectArgs testbucket = UploadObjectArgs.builder().bucket("testbucket")
// .object("test001.mp4").object("001/test001.mp4")//添加子目录.filename("D:\\develop\\upload\\1mp4.temp").contentType(mimeType)//默认根据扩展名确定文件内容类型，也可以指定.build();minioClient.uploadObject(testbucket);System.out.println("上传成功");} catch (Exception e) {e.printStackTrace();System.out.println("上传失败");}}2.删除
@Test
public void delete(){try {minioClient.removeObject(RemoveObjectArgs.builder().bucket("testbucket").object("001/test001.mp4").build());System.out.println("删除成功");} catch (Exception e) {e.printStackTrace();System.out.println("删除失败");}
}3. ☆查询文件 (后端处理同文件判断，同一文件秒传)
@Transactional@ApiOperation("上传一个文件")@RequestMapping(value = "/uploadfild",method = RequestMethod.POST)public ResponseUtils fileupload(@RequestParam("file") MultipartFile multipartFile, @RequestParam(defaultValue = "****") String bucket, @RequestParam(required = false) String objectName) throws Exception {MediaResources mediaResources = new MediaResources();/*** 方法默认的保存路径为：C:\Documents and Settings\Administrator\Local Settings\Temp*///立即删除文件 file.delete(); //在JVM退出时删除文件 file.deleteOnExit();File tempFile = File.createTempFile("minio","temp");/*** 先获取流 后面会改变*/InputStream stream = multipartFile.getInputStream();/*** 上传的文件拷贝到临时文件*/multipartFile.transferTo(tempFile);String absolutePath = tempFile.getAbsolutePath();FileInputStream fileInputStream = new FileInputStream(new File(absolutePath));String s_md5 = DigestUtils.md5Hex(fileInputStream);//删除tempFile.delete();/*** 数据放入*/mediaResources.setFileUniqueValue(s_md5);mediaResources.setBucket(bucket);mediaResources.setAccessAddress("/"+bucket+"/"+multipartFile.getOriginalFilename());mediaResources.setUploadedBy("zhan_yuan");mediaResources.setUploadTime(new Date());mediaResources.setState("以审核");String[] s = multipartFile.getOriginalFilename().split("\\.");ContentInfo ex = ContentInfoUtil.findExtensionMatch("."+s[1]);mediaResources.setFileType(ex.getMimeType());mediaResources.setFileName(multipartFile.getOriginalFilename());/*** 新增*/mediaResourcesService.save(mediaResources);minioUtil.createBucket(bucket);if(objectName != null) minioUtil.uploadFile(stream,bucket,objectName+"/"+multipartFile.getOriginalFilename());else minioUtil.uploadFile(stream,bucket,multipartFile.getOriginalFilename());return ResponseUtils.success("/"+bucket+"/"+multipartFile.getOriginalFilename());}
