SSM框架介紹

SPRing框架介紹

Spring是一個(gè)開源框架，Spring是于2003 年興起的一個(gè)輕量級的java 開發(fā)框架，由Rod Johnson 在其著作Expert One-On-One J2EE Development and Design中闡述的部分理念和原型衍生而來。它是為了解決企業(yè)應(yīng)用開發(fā)的復(fù)雜性而創(chuàng)建的。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。簡單來說，Spring是一個(gè)輕量級的控制反轉(zhuǎn)（IoC）和面向切面（AOP）的容器框架。

Spring Mvc框架介紹

Spring MVC屬于SpringFrameWork的后續(xù)產(chǎn)品，已經(jīng)融合在Spring Web Flow里面。Spring MVC 分離了控制器、模型對象、分派器以及處理程序?qū)ο蟮慕巧@種分離讓它們更容易進(jìn)行定制。

Mybatis框架介紹

MyBatis 本是apache的一個(gè)開源項(xiàng)目iBatis, 2010年這個(gè)項(xiàng)目由apache software foundation 遷移到了google code，并且改名為MyBatis 。MyBatis是一個(gè)基于Java的持久層框架。iBATIS提供的持久層框架包括SQL Maps和Data access Objects（DAO）MyBatis 消除了幾乎所有的JDBC代碼和參數(shù)的手工設(shè)置以及結(jié)果集的檢索。MyBatis 使用簡單的 xml或注解用于配置和原始映射，將接口和 Java 的POJOs（Plain Old Java Objects，普通的 Java對象）映射成數(shù)據(jù)庫中的記錄。
