1. 引入依赖

          <!-- MinIO --><dependency><groupId>io.minio</groupId><artifactId>minio</artifactId><version>8.2.1</version></dependency>

2. yml配置

# MinIO 配置
minio:endpoint: http://192.168.45.85:9000      # MinIO服务地址fileHost: http://192.168.45.85:9000      # 文件地址hostbucketName: imooc                      # 存储桶bucket名称accessKey: imooc                         # 用户名secretKey: imooc123456                     # 密码imgSize: 1024                           # 图片大小限制，单位：mfileSize: 1024

3. 客户端配置

}
