【SpringBoot二手交易系統全解析】從0到1搭建你的專屬平臺！

🔍 需求確認：溝通對接 🗣

💬 在項目啟動初期，我通過多次線上會議和需求文檔，與客戶深入交流，明確了系統需要支持的核心功能：商品分類、二手商品展示、訂單處理、取消購買、收發貨管理、配送跟蹤、留言反饋及系統設置等。📝

📊 系統功能結構：附思維導圖

思維導圖，展示各模塊間的邏輯關系，從用戶界面到后臺管理，層層遞進！

☆開發技術：

1、環境

（1）運行環境：java jdk 1.8，node 14。

（2）IDE環境：IDEA或者Eclipse; Visual Studio Code 或 WebStorm 均可；

（3）硬件環境：windows 10/11 或者 Mac OS；

（4）數據庫：MySql 5.7/8.0版本均可；

（5）Maven項目：maven 3.6;

2、技術棧

后臺：SpringBoot + Mybatis-plus + Mybatis + lombok插件等

前臺：Vue + Vue Router + ELementUI + Axios 等

3、使用說明

先啟動后端再啟動前端

4、后端：

（1）使用Navicat或者idea自帶的數據庫工具，在mysql中創建對應sql文件名稱的數據庫，并導入項目的sql文件；

（2）使用IDEA/Eclipse導入后端項目，導入成功后執行maven clean;maven install命令，然后運行；

（3）將項目中application.yml配置文件中的數據庫配置改為自己的配置;

（4）運行項目，后端運行成功后再運行前端項目；

5、前端:

（1）安裝好node及npm，通過命令node -v和npm -v 查看安裝是否成功；

（2）在Visual Studio Code 或 WebStorm 中打開front所在路徑；

（3）命令行執行npm run serve啟動項目；

🛠 系統功能：運行截圖展示

商品分類管理：靈活添加、編輯、刪除分類，讓商品井井有條！（圖2）

二手商品管理：上傳商品圖片、詳情，輕松管理庫存，讓二手好物找到新家！（圖3）

訂單信息管理：實時查看訂單狀態，處理退款、發貨等操作，交易更順暢！（圖4）

取消購買管理：用戶友好界面一鍵取消訂單，系統自動處理退款流程，確保交易靈活無憂！（圖5）

收貨信息管理：用戶可保存多個收貨地址，購物時快速選擇，收貨更便捷；商家端清晰查看收貨詳情，發貨不出錯！（圖6）

留言反饋系統：搭建用戶與商家溝通的橋梁，無論是咨詢商品詳情還是售后問題，都能得到及時響應，提升用戶滿意度！（圖7）
