docker服务器先下载minio镜像

安装脚本:

#创建映射文件夹
mkdir -p /home/minio/data /home/minio/config
#后台启动镜像
docker run -itd -p 9000:9000 --name minio1 \
  -e "MINIO_ACCESS_KEY=AKIAIOSFODNN7EXAMPLE" \
  -e "MINIO_SECRET_KEY=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY" \
  -v /home/minio/data:/data \
  -v /home/minio/config:/root/.minio \
  minio/minio server /data

方案一：

启动文件上传项目，按照文件提示进行上传下载

方案二：

改造上传下载项目的源代码

①：加入依赖

        <dependency>
            <groupId>io.minio</groupId>
            <artifactId>minio</artifactId>
            <version>8.3.3</version>
        </dependency>
        <dependency>
            <groupId>com.squareup.okhttp3</groupId>
            <artifactId>okhttp</artifactId>
            <version>4.8.1</version>
        </dependency>

②：改造代码；JDK版本1.8/spring 微服务版本：2021.1

添加配置：

#文件服务器地址
minio.host=http://minio文件服务器端口:9000
local.host=http://应用服务器部署ip:网管端口
minio.accessKey=AKIAIOSFODNN7EXAMPLE
minio.secretKey=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY

把下面代码复制到项目中：
