今天通过docker安装了一个minio的容器 ，用来存储文件和图片 ，使用的命令为

docker pull minio/minio:RELEASE.2021-01-16T02-19-44Z
docker run --name minio -p 9000:9000 -d \
-v /home/root/data/minio/data:/data \
-v /home/root/data/minio/config:/root/.minio \
-e "MINIO_ACCESS_KEY=admin" -e "MINIO_SECRET_KEY=123@newedu.com" \
--restart=always minio/minio:RELEASE.2021-01-16T02-19-44Z  server /data 
然后想通过java程序来进行上传文件的存储  ，写好了，记录一下
一：加入依赖
<!--  minio的依赖-->
        <dependency>
            <groupId>io.minio</groupId>
            <artifactId>minio</artifactId>
            <version>8.2.2</version>
            <scope>compile</scope>
        </dependency>
<form action="uploadFile" method="post" enctype="multipart/form-data">
    <p>请选择文件：<input type="file" name="file"></p>
    <p><button>上传</button></p>
</form>
package com.example.testboot.config;
import io.minio.MinioClient;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
 * Minio 配置类
@Configuration
@ConfigurationProperties(prefix = "minio")
public class MinioConfig
     * 服务地址
    private String url;
     * 用户名
    private String accessKey;
    private String secretKey;
     * 存储桶名称
    private String bucketName;
    public String getUrl()
        return url;
    public void setUrl(String url)
        this.url = url;
    public String getAccessKey()
        return accessKey;
    public void setAccessKey(String accessKey)
        this.accessKey = accessKey;
    public String getSecretKey()
        return secretKey;
    public void setSecretKey(String secretKey)
        this.secretKey = secretKey;
    public String getBucketName()
        return bucketName;
    public void setBucketName(String bucketName)
        this.bucketName = bucketName;
    @Bean
    public MinioClient getMinioClient()
        return MinioClient.builder().endpoint(url).credentials(accessKey, secretKey).build();
请求控制类
