版本选择
- JDK 1.8
1. CentOS安装MinIO
https://blog.csdn.net/llwy1428/article/details/99618252
2. 创建Bucket
在MinIO控制台中创建Bucket：springboot-minio-demo
3. 创建Maven项目
3.1. 项目结构
3.2. pom.xml引入依赖

3.3. application.yaml 配置MinIO
server:
port: 8080
tomcat:
connection-timeout: 10000 # 10s
minio:
endpoint: 192.168.0.121
port: 9000
accessKey: minioadmin
secretKey: minioadmin
secure: false
bucketName: springboot-minio-dev
3.4. SpringBoot启动类
