首先说一下从零开始自己去搭一个fastdfs挺麻烦，后来看到有人把做好的 docker 镜像传出来了，那搭建起来就很容易了

有服务器的可以自己在服务器上玩玩,没有的可以新建一个centos7.5虚拟机玩玩，遇到虚拟机不能上网和换阿里云的源的问题可以参考https://blog.csdn.net/qq_37759106/article/details/82985113这篇文章

PS：更多 Docker 和 Spring Boot 的文章可以关注微信公众号「Java后端」回复「666」下载技术栈手册。

1.第一步安装docker:

 在 root 权限下

yum install -y docker-io #安装docker
service docker star #启动docker
docker -v # 查看docker版本

2. 拉取镜像

docker pull qbanxiaoli/fastdfs

启动 fastdfs

docker run -d --restart=always --privileged=true --net=host --name=fastdfs -e IP=192.168.127.131 -e WEB_PORT=80 -v ${HOME}/fastdfs:/var/local/fdfs qbanxiaoli/fastdfs

IP 后面是你的服务器公网ip或者虚拟机的IP，-e WEB_PORT=80 指定 nginx 端口

测试fastdfs是否搭建成功

docker exec -it fastdfs /bin/bash
echo "Hello FastDFS!">index.html
fdfs_test /etc/fdfs/client.conf upload index.html

能返回 url 就意见搭建成功

这样 fastdfs 就搭建好啦

下面进入 Spring Boot 整合部分

<groupId>com.github.tobato</groupId><artifactId>fastdfs-client</artifactId>
<version>1.26.2</version>

在 Spring Boot 启动类上加

@Import(FdfsClientConfig.class)
@EnableMBeanExport(registration = RegistrationPolicy.IGNORE_EXISTING)

创建FastDFSClient工具类

配置yml文件

测试类
@RunWith(SpringRunner.class)
@SpringBootTest
public class FileClientApplicationTests {@Testpublic void Upload() {String fileUrl = this.getClass().getResource("/test.jpg").getPath();File file = new File(fileUrl);String str = FastDFSClient.uploadFile(file);FastDFSClient.getResAccessUrl(str);}@Testpublic void Delete() {FastDFSClient.deleteFile("group1/M00/00/00/rBEAClu8OiSAFbN_AAbhXQnXzvw031.jpg");}
}

运行测试类

返回的 url 就是能访问的地址
