手把手Maven搭建SpringMVC+Spring+MyBatis框架

SSM（Spring+SpringMVC+Mybatis），目前较为主流的企业级架构方案。标准的MVC设计模式，将整个系统划分为显示层、Controller层、Service层、Dao层四层，使用SpringMVC负责请求的转发和视图管理，Spring实现业务对象管理, MyBatis作为数据对象持久化引擎。

一. 框架详情

Spring 是一个轻量级的Java开发框架，它是为了解决企业应用开发的复杂性而创建的。Spring的用途不仅限于服务器端的开发。从简单性、可测试性和松耦合的角度而言，任何Java应用都可以从Spring中受益。简单来说，Spring是一个轻量级的控制反转（IoC）和面向切面（AOP）的容器框架。
SpringMVC 属于SpringFrameWork的后续产品，分离了控制器、模型对象、分派器以及处理程序对象的角色，这种分离让它们更容易进行定制。
MyBatis 是一个基于Java的持久层框架。MyBatis提供的持久层框架包括SQL Maps和Data Access Objects（DAO）它消除了几乎所有的JDBC代码和参数的手工设置以及结果集的检索。MyBatis 使用简单的 XML或注解用于配置和原始映射，将接口和 Java映射成数据库中的记录。

二. 创建Maven项目

Eclipse中用Maven创建项目
按默认Next
找到maven-archetype-webapp后，点击next
填写相应的信息，GroupID是项目组织唯一的标识符，实际对应JAVA的包的结构。ArtifactID就是项目的唯一的标识符，实际对应项目的名称，就是项目根目录的名称。Package填了默认给你建一个包，不写也可以。
刚建好的目录如下
Maven规定必须添加以下Source Folder：
src/main/resources
src/main/java
src/test/resources
src/test/java
在这步之前最好先项目上右键选择properties，然后点击java build path，在Librarys下，编辑JRE System Library，选择workspace default jre。
分别修改输出路径为，对应关系如下：
将项目转换成Dynamic Web Project，在项目上右键Properties，在左侧选择 Project Facets。
设置部署时的文件发布路径，删除test的两项，因为test是测试使用，并不需要部署。
设置将Maven的jar包发布到lib下。Add -> Java Build Path Entries -> Maven Dependencies -> Finish

三. Maven引入需要的JAR包

Xml代码

四. 相关配置文件配置，整合SSM框架

web.xml
Java代码

spring.xml
Java代码

为了代替手工使用 SqlSessionDaoSupport 或 SqlSessionTemplate 编写数据访问对象 (DAO)的代码,MyBatis-Spring 提供了一个动态代理的实现:MapperFactoryBean。这个类可以让你直接注入数据映射器接口到你的 service 层 bean 中。当使用映射器时,你仅仅如调用你的 DAO 一样调用它们就可以了,但是你不需要编写任何 DAO 实现的代码,因为 MyBatis-Spring 将会为你创建代理。
