使用docker安装minio（spring boot使用）

查看docker环境是否正常

docker search minIO

下载minIO的镜像

docker pull minio/minio

创建minIO容器

查看所有镜像

docker images

创建目录：

mkdir -p /data/minio/config
mkdir -p /data/minio/data

创建并启动minIO容器： 这里的 \ 指的是命令还没有输入完，还需要继续输入命令，先不要执行的意思。 这里的9090端口指的是minio的客户端端口。虽然设置9090，但是我们在访问9000的时候，他会自动跳到9090。

docker run -p 9091:9091 -p 9090:9090 \
 --net=host \
 --name minio \
 -d --restart=always \
 -e "MINIO_ACCESS_KEY=admin" \
 -e "MINIO_SECRET_KEY=Cjw970404" \
 -v /docker/minio/data:/docker/minio/data \
 -v /docker/minio/config:/docker/minio/config \
 minio/minio server \
 /data --console-address ":9090" -address ":9091"


 # 设置为和 docker 绑定启动,docker 启动则 minio 就启动
docker update --restart=always

访问地址

http://ip:9090

到这里。minio就算安装完成了

SpringBoot整合Minio

首先我们先要导入项目依赖

导入依赖

<dependency>
    <groupId>io.minio</groupId>
    <artifactId>minio</artifactId>
    <version>8.2.2</version>
</dependency>

application.properties配置信息

这边的配置，需要自己根据需求进行配置。

# 限制上传文件大小
spring.servlet.multipart.max-file-size=200MB
spring.servlet.multipart.max-request-size=200MB

# minio配置
minio.endpoint=http://*.*.*.*:9001
minio.bucketName=taluohui
minio.accessKey=admin
minio.secretKey=Cjw970404

MinioConfig.class配置类

将配置文件中的配置读取出来，并进行MinioClient的配置申明。

@Data
@Configuration
@ConfigurationProperties(prefix = "minio")
public class MinioConfig {

    @Value("${minio.url}")
    private String endpoint;

    @Value("${minio.accessKey}")
    private String accessKey;

    @Value("${minio.secretKey}")
    private String secretKey;

    @Value("${minio.bucketName}")
    private String bucketName;

    @Bean
    public MinioClient minioClient() {
        return MinioClient.builder()
                .endpoint(endpoint)
                .credentials(accessKey, secretKey)
                .build();
    }
}

minio工具类

实现minio的配置方法，更加方便我们之后的时候。

文件处理接口

实现文件增删改查等操作的接口。

@Api(tags = "文件相关接口")
@Slf4j
@RestController

    public JsonResponse getAllBuckets() {
        List<Bucket> allBuckets = minioUtil.getAllBuckets();
        return new JsonResponse<>(allBuckets);
    }

    @ApiOperation(value = "文件上传返回url")
    @PostMapping("/upload")

    public JsonResponse download(@RequestParam("fileName") String fileName, HttpServletResponse res) {
        minioUtil.download(fileName,res);
        return JsonResponse.success();
    }

    @ApiOperation(value = "删除文件", notes = "根据url地址删除文件")
    @PostMapping("/delete")
    public JsonResponse remove(String url) {
        String objName = url.substring(url.lastIndexOf(prop.getBucketName()+"/") + prop.getBucketName().length()+1);
        minioUtil.remove(objName);
        return JsonResponse.success(objName);
    }
}

解决链接7天失效问题

访问minio的管理界面，点击对应的存储桶的设置 Access Policy选项选择custom 将其中的ListBucket配置删除掉，这样别人就没办法通过存储桶地址获取所有图片，并删除图片了。
