springboot整合minio

minio安装参考

1. 添加依赖

        <dependency>
            <groupId>io.minio</groupId>
            <artifactId>minio</artifactId>
            <version>${minio.version}</version>
        </dependency>

2. 配置

2.1 yml配置minio相关信息

minio:
  endpoint: http://192.168.31.48:9000
  accessKey: root
  secretKey: root@123456!
  bucketName: test-bucket
