1.MinioConfig配置类
@Configuration @ConfigurationProperties(prefix = "minio") @Data public class MinioConfig { /** * minio部署的机器ip地址 */ @Value("${minio.endpoint}") private String endpoint; /** * minio使用的端口 */ @Value("${minio.port}") private Integer port; /** *唯一标识的账户 */ @Value("${minio.accessKey}") private String accessKey; /** * 账户的密码 */ @Value("${minio.secretKey}") private String secretKey; /** * 如果是true,则用的是https而不是http,默认值是true */ @Value("${minio.secure}") private Boolean secure; /** * 默认使用的桶名称 */ @Value("${minio.bucketName}") private String defaultBucketName; /** * 对象交给spring管理 */ @Bean public MinioClient getMinioClient() { MinioClient minioClient = MinioClient.builder() .endpoint(endpoint , port , secure) .credentials(accessKey, secretKey) .build(); return minioClient; } }

3.对应使用方法文章来源地址https://www.toymoban.com/news/detail-514821.html
public class SysFileServiceImpl extends ServiceImpl<SysFileMapper, SysFile> implements SysFileService { @Resource private MinioConfig minioConfig; @Autowired private MinioUtil minioUtil; @Resource SysFileMapper sysFileMapper; @Override public HashMap<String, String> uploadFile(MultipartFile file) { //上传minio String bucketName = minioConfig.getDefaultBucketName(); //桶 String fileCode = IdUtil.simpleUUID(); String fileName = file.getOriginalFilename(); //文件名称 String fileUrl = minioUtil.getDatePath() + fileCode + "_"+fileName; //文件存放路径 minioUtil.upload(bucketName, fileUrl, file); //保存文件 SysFile sysFile = new SysFile(); sysFile.setName(fileName); sysFile.setUrl(fileUrl); sysFileMapper.insert(sysFile); //返回数据 HashMap<String, String> objectInfo = new HashMap<>(); objectInfo.put("fileName", fileName); //只能预览图片、txt等部分文件 String viewPath = minioUtil.getPresignedObjectUrl(bucketName, fileUrl, 1, TimeUnit.DAYS); objectInfo.put("viewPath", viewPath); objectInfo.put("fileId", String.valueOf(sysFile.getId())); return objectInfo; } @Override public String getFileUrl(String fieldId) { String bucketName = minioConfig.getDefaultBucketName(); SysFile sysFile = sysFileMapper.selectById(fieldId); return minioUtil.preview(sysFile.getUrl(),bucketName); } }
