1、 項目簡介
1.1、 簡介
智慧校園管理系統(tǒng)：主要是以年級、班級為單位，進(jìn)行老師和學(xué)生信息記錄和統(tǒng)計功能。項目采用前后端分離架構(gòu)思想，前端采用 HTML+CSS+VUE來實現(xiàn)頁面效果展示，后端采用 SpringBoot+MybatisPlus 框架實現(xiàn)數(shù)據(jù)存儲等服務(wù)。存儲層使用高性能的 MySQL，服務(wù)器使用 SpringBoot 內(nèi)置的Tomcat9.x，項目構(gòu)建工具使用Maven來管理jar包和項目構(gòu)建。
1.2、 項目模塊
1.3 使用的技術(shù)
2、 項目環(huán)境搭建
2.1、使用IDEA的SpringBoot創(chuàng)建一個Maven項目
設(shè)置好包名及存放的位置即可，無需添加其他功能，后面會對Pom.xml進(jìn)行修改，其他功能可以通過maven即可。
2.2 pom.xml 導(dǎo)入依賴
為了避免影響其他插件的使用，需要使用較低的 SpringBoot 的版本
由于我的數(shù)據(jù)庫是 mysql5.7，導(dǎo)入的依賴也應(yīng)該是 5.x 版本的

完成以上搭建后，應(yīng)該可以實現(xiàn)對首頁的訪問，但我這里失敗了。后來發(fā)現(xiàn)是因為數(shù)據(jù)庫版本的不一致的問題。
由于我的 MySQL 版本為 5.7，這里需要在 pom.xml 中更改導(dǎo)入的數(shù)據(jù)庫驅(qū)動版本
<dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.38</version></dependency>application.yaml 中數(shù)據(jù)庫的配置也要與 5.7 版本的格式對應(yīng)
