前兩篇總體上介紹了經過 Nginx 和 FastDFS 的整合來實現文件服務器。可是,在實際開發中對圖片或文件的操做都是經過應用程序來完成的,所以,本篇將介紹 Spring Boot 整合 FastDFS 客戶端來實現對圖片/文件服務器的訪問。html
若是有不瞭解 FastDFS 的讀者能夠先瀏覽《CentOS7 安裝FastDFS分佈式文件系統》或是另行查閱網上相關資料。java
項目總體的代碼結構圖以下:mysql

注意: FastDFS的第三方客戶端包引入的時候要去除logback的包,否則與log4j2衝突,啓動會報錯docker

而後經過swagger-ui的接口直接測試文件上傳功能
