Spring簡單介紹Spring是一個開源框架，Spring是于2003年興起的一個輕量級的Java開發框架，簡單來說，Spring是一個 分層的JavaSE/EEfull-stack(一站式) 輕量級開源框架。總結幾點： 1) spring是輕量級的，而且是開放源碼的。 2) spring有控制反轉和依賴注入的特性，將類之間的主動關聯轉換為被動關聯，實現的相互間的解耦， 通過配置文件，簡化了開發； 3) aop面向切面編程，將系統核心業務與服務分離，實現了代碼的解耦，通過切面實現全局調用， 如日志，事務等； 4) 與其他框架能很好的集成，如mybatis,struts2,hibernate,redis等。4. mybatis簡單介紹 MyBatis是支持定制化 SQL、存儲過程以及高級映射的優秀的持久層框架。MyBatis避免了幾乎所有的 JDBC代碼和手動設置參數以及獲取結果集。MyBatis可以對配置和原生Map使用簡單的 XML或注解， 將接口和Java的 POJOs(Plain Old Java Objects,普通的 Java對象)映射成數據庫中的記錄。mybatis相對hibernate優勢 1) mybatis是輕量級的，學習成本較低，易上手； 2) mybatis是半自動化的，相關的sql需要手動實現；5.
