基於SpringMVC+Spring+Hibernate+Maven+Bootstrap的簡單Demo
阿新 • • 發佈：2019-01-29
趁著週末自己複習搭建了一個SpringMVC小demo。有很多不正之處還請指教。有什麼問題可以私信或者下方留言。有關Ioc可以參考Spring Ioc詳細配置與使用,有關AOP可以參考SpringAOP詳細配置與使用
專案用到的技術：
開發環境IDE eclipse Neon
伺服器Tomcat8.0
JDK 1.8 （正在學習1.8所以還沒有使用到新的語法）
資料庫 Mysql5.5
Maven 3.3.9
分頁框架 pager taglib
後臺框架 Spring4.2.4 SpringMVC4.2.4 Hibernate4.3.10
前端框架 Bootstrap3.3.10
日誌採用了 log4j
測試框架 Spring-test + junit4
