springboot+vue实现Minio文件存储的示例代码
作者:今年不养猪只除草
本文主要介绍了springboot+vue实现Minio文件存储的示例代码,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧
安装minio
首先点击进入MINIO官网,进行一个minio服务器的下载
下载好了之后在本地磁盘找一个文件夹,把下载的exe放入文件夹,再新建一个文件夹准备存放数据和文件
在当前目录cmd进入控制台,输入代码
minio.exe server data
成功后会有访问路径以及账号密码
访问这个路径,输入刚刚控制台打印的账号密码就可以进入
http://127.0.0.1:9000
进入后创建buckets
后端
在官网找到依赖并导入
<dependency> <groupId>io.minio</groupId> <artifactId>minio</artifactId> <version>8.4.3</version> </dependency>
添加yml文件配置
# Minio配置 wyj配置 minio: endpoint: http://127.0.0.1:9000 accessKey: minioadmin secretKey: minioadmin bucketName: svt-ttt
MinIoClientConfig配置文件
这里bean文件只能有这一个,如果是多人团队项目开发记得在测试的时候协商好@Value
的注解导入是spring的原生注解
package com.wedu.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; /* * Minio的配置类 * */ @Data @Component public class MinIoClientConfig { @Value("${minio.endpoint}") private String endpoint; @Value("${minio.accessKey}") private String accessKey; @Value("${minio.secretKey}") private String secretKey; @Value("${minio.bucket-name}") private String bucketName; /** * 注入minio 客户端 * * @return */ @Bean public MinioClient minioClient() { return MinioClient.builder() .endpoint(endpoint) .credentials(accessKey, secretKey) .build(); } }
工具类MinIOUtil
工具类里有很多可使用的方法,这里只用到了uploadFile
package com.wedu.modules.tain.utils; import com.amazonaws.util.IOUtils; import com.wedu.modules.equi.entity.ObjectItem; import io.minio.*; import io.minio.messages.DeleteError; import io.minio.messages.DeleteObject; import io.minio.messages.Item; import lombok.SneakyThrows; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.boot.context.properties.ConfigurationProperties;

@Value("${minio.access-key}") private String accessKey; @Value("${minio.secret-key}") private String secretKey; @Value("${minio.bucket-name}") private String bucketName; /** * 上传文件到指定的存储桶中 * * @param bucketName 存储桶名称 * @param file 上传的文件 * @param objectName 存储对象的名称 * @param contentType 文件的内容类型 * @return 文件上传的响应对象 * @throws Exception 如果上传过程中发生异常 */ @SneakyThrows(Exception.class) public ObjectWriteResponse uploadFile(String bucketName, MultipartFile file, String objectName, String contentType) { InputStream inputStream = file.getInputStream(); return minioClient.putObject( PutObjectArgs.builder() .bucket(bucketName) .object(objectName) .contentType(contentType) .stream(inputStream, inputStream.available(), -1) .build()); } /** * description: 判断bucket是否存在,不存在则创建 * * @return: void */ 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(); } } /** * 创建存储bucket * @param bucketName 存储bucket名称 * @return Boolean */ public Boolean makeBucket(String bucketName) { try { minioClient.makeBucket(MakeBucketArgs.builder() .bucket(bucketName) .build()); } catch (Exception e) { e.printStackTrace(); return false; } return true; } /** * 删除存储bucket * @param bucketName 存储bucket名称 * @return Boolean */ public Boolean removeBucket(String bucketName) { try { minioClient.removeBucket(RemoveBucketArgs.builder() .bucket(bucketName) .build()); } catch (Exception e) { e.printStackTrace(); return false; } return true; } /** * description: 上传文件 * * @param multipartFile * @return: java.lang.String */ public List<String> upload(MultipartFile[] multipartFile) { List<String> 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; } /** * description: 下载文件 * * @param fileName * @return: org.springframework.http.ResponseEntity<byte [ ]> */ public ResponseEntity<byte[]> download(String fileName) { ResponseEntity<byte[]> 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<byte[]>(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; } /** * 查看文件对象 * @param bucketName 存储bucket名称 * @return 存储bucket内文件对象信息 */ public List<ObjectItem> listObjects(String bucketName) { Iterable<Result<Item>> results = minioClient.listObjects( ListObjectsArgs.builder().bucket(bucketName).build()); List<ObjectItem> objectItems = new ArrayList<>(); try { for (Result<Item> 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; } /** * 批量删除文件对象 * @param bucketName 存储bucket名称 * @param objects 对象名称集合 */ public Iterable<Result<DeleteError>> removeObjects(String bucketName, List<String> objects) { List<DeleteObject> dos = objects.stream().map(e -> new DeleteObject(e)).collect(Collectors.toList()); Iterable<Result<DeleteError>> results = minioClient.removeObjects(RemoveObjectsArgs.builder().bucket(bucketName).objects(dos).build()); return results; } }
controller调用uploadFile
@Autowired private MinIOUtil minIOUtil; @Autowired private MinIoClientConfig minIoClientConfig; //minio @PostMapping("/minIoUpload") public R minIoUpload(@RequestParam("file") MultipartFile file) throws IOException { //文件名 String fileName = file.getOriginalFilename(); String newFileName = System.currentTimeMillis() + "." + StringUtils.substringAfterLast(fileName, "."); //类型 String contentType = file.getContentType(); minIOUtil.uploadFile(minIoClientConfig.getBucketName(), file, newFileName, contentType); return R.ok("上传成功"); }
postman测试
测试成功
前端
主页面和springboot+vue实现oss文件存储一样,在弹窗的下拉框中添加一个2,访问路径变为自己的post的访问路径即可
