SpringBoot2.0集成FastDFS
前两篇整体上介绍了通过 Nginx 和 FastDFS 的整合来实现文件服务器。但是，在实际开发中对图片或文件的操作都是通过应用程序来完成的，因此，本篇将介绍 Spring Boot 整合 FastDFS 客户端来实现对图片/文件服务器的访问。
如果有不了解 FastDFS 的读者可以先浏览《CentOS7 安装FastDFS分布式文件系统》或是另行查阅网上相关资料。
一、整合编码
项目整体的代码结构图如下：

我在里面添加了Mybatis和数据连接驱动，使用的日志系统是Solf4j,log4j2

注意： FastDFS的第三方客户端包引入的时候要去除logback的包，不然与log4j2冲突,启动会报错

测试效果
然后通过swagger-ui的接口直接测试文件上传功能
