引入依赖
<dependency> <groupId>io.minio</groupId> <artifactId>minio</artifactId> <version>7.1.0</version> </dependency>
也用到了这个 如果已经引入就不需要
<dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency>
配置文件yml
minio: url: http://192.168.80.134:9000 access-key: AKIAiosFODNN7EXAMPLE secret-key: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY bucket-name: test
MinioProperties.java
import lombok.Data; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.context.annotation.Configuration; /** * @author * @date 2021/06/25 */ @Data @Configuration @ConfigurationProperties(prefix = "minio") public class MinioProperties { /** * minio 服务地址 http://ip:port */ private String url; /** * 用户名 */ private String accessKey; /** * 密码 */ private String secretKey; /** * 桶名称 */ private String bucketName; }
工具类
MinIoUtil.java
import com.example.minio.config.MinioProperties; import io.minio.MinioClient; import io.minio.ObjectStat; import io.minio.PutObjectOptions; import io.minio.messages.Bucket; import lombok.SneakyThrows; import lombok.extern.slf4j.Slf4j; import org.apache.tomcat.util.http.fileupload.IOUtils; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import org.springframework.web.multipart.MultipartFile; import javax.annotation.PostConstruct; import javax.servlet.http.HttpServletResponse; import java.io.InputStream; import java.net.URLEncoder; import java.util.List; /** * * Minio工具类 */ @Slf4j @Component public class MinIoUtil { public static MinioClient minioClient; @Autowired private MinioProperties minioProperties; public static MinIoUtil minIoUtil; /** * 初始化minio配置 */ @PostConstruct public void init() { minIoUtil=this; minIoUtil.minioProperties=this.minioProperties; try { minioClient = MinioClient.builder().endpoint(minioProperties.getUrl()).credentials(minioProperties.getAccessKey(),minioProperties.getSecretKey()).build(); createBucket(minioProperties.getBucketName()); log.info(">>>>>>>>>>>minio 初始化成功"); } catch (Exception e) { e.printStackTrace(); log.error("》》》》》》》》》》初始化minio异常: 【{}】", e.fillInStackTrace()); } } /** * 判断 bucket是否存在 * * @param bucketName 桶名 * @return: boolean */ @SneakyThrows(Exception.class) public static boolean bucketExists(String bucketName) { return minioClient.bucketExists(bucketName); } /** * 创建 bucket * @param bucketName 桶名 * @return: void */ @SneakyThrows(Exception.class) public static void createBucket(String bucketName) { boolean isExist = minioClient.bucketExists(bucketName); if (!isExist) { minioClient.makeBucket(bucketName); } } /** * * 获取全部bucket * @return: java.util.List<io.minio.messages.Bucket> */ @SneakyThrows(Exception.class) public static List<Bucket> getAllBuckets() { return minioClient.listBuckets(); } /** * 文件上传 * @param bucketName 桶名 * @param fileName 文件名 * @param filePath 文件路径 */ @SneakyThrows(Exception.class) public static void upload(String bucketName, String fileName, String filePath) { minioClient.putObject(bucketName, fileName, filePath, null); } /** * 文件上传(返回URL下载地址) * @param bucketName 桶名 * @param fileName 文件名 * @param stream 文件流 * @return: 文件url下载地址 */ @SneakyThrows(Exception.class) public static String upload(String bucketName, String fileName, InputStream stream) { minioClient.putObject(bucketName, fileName, stream, new PutObjectOptions(stream.available(), -1)); return getFileUrl(bucketName, fileName); } /** * 文件上传 (返回URL下载地址) * @param bucketName 桶名 * @param file 文件 * @return: 文件url下载地址 */ @SneakyThrows(Exception.class) public static String upload(String bucketName, MultipartFile file) { final InputStream is = file.getInputStream(); final String fileName = file.getOriginalFilename(); minioClient.putObject(bucketName, fileName, is, new PutObjectOptions(is.available(), -1)); is.close(); return getFileUrl(bucketName, fileName); } /** * 删除文件 * @param bucketName 桶名 * @param fileName 文件名 */ @SneakyThrows(Exception.class) public static void deleteFile(String bucketName, String fileName) { minioClient.removeObject(bucketName, fileName); } /** * 下载文件 (流输出) * @param bucketName 桶名 * @param fileName 文件名 */ @SneakyThrows(Exception.class) public static void download(String bucketName, String fileName, HttpServletResponse response) { // 获取对象的元数据 final ObjectStat stat = minioClient.statObject(bucketName, fileName); response.setContentType(stat.contentType()); response.setCharacterEncoding("UTF-8"); response.setHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode(fileName, "UTF-8")); InputStream is = minioClient.getObject(bucketName, fileName); IOUtils.copy(is, response.getOutputStream()); is.close(); } /** * * 获取minio文件的下载地址 * @param bucketName 桶名 * @param fileName 文件名 */ @SneakyThrows(Exception.class) public static String getFileUrl(String bucketName, String fileName) { return minioClient.presignedGetObject(bucketName, fileName); } }
使用直接调用工具类的方法即可 例如
@PostMapping(value = "/upload") public String upload(@RequestParam(value = "file") MultipartFile file){ String upload = MinIoUtil.upload("test", file); return upload; }
