spring在英文里有春天、彈簧、跳躍和泉眼的意思。Spring 也表示是一個(gè)開源框架,是為了解決企業(yè)應(yīng)用程序開發(fā)復(fù)雜性由Rod Johnson創(chuàng)建的。框架的主要優(yōu)勢之一就是其分層架構(gòu),分層架構(gòu)允許使用者選擇使用哪一個(gè)組件,同時(shí)為 J2EE 應(yīng)用程序開發(fā)提供集成的框架。Spring使用基本的JavaBean來完成以前只可能由EJB完成的事情。然而,Spring的用途不僅限于服務(wù)器端的開發(fā)。從簡單性、可測試性和松耦合的角度而言,任何Java應(yīng)用都可以從Spring中受益。
