SSM：SpringMVC、Spring、Mybatis三大框架。
Spring 在其中充当粘合剂的作用，无条件管理SpringMVC和Mybatis两大框架。
其中，Spring和SpringMVC其实可以说是父子关系，但是它们并不是同一个容器。故Spring 粘合 SpringMVC可以做到无缝集成；
Spring 粘合 Mybatis 需要通过 SqlSessionFactoryBean 对象以及通过 MapperScannerConfigurer 对象来为Mapper接口创建代理对象以便将Mapper接口“实例化”并执行。
SpringMVC 核心配置 applicationContext-mvc.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:context="http://www.springframework.org/schema/context" 4 xmlns:aop="http://www.springframework.org/schema/aop" 5 xmlns:mvc="http://www.springframework.org/schema/mvc" 6 xmlns:tx="http://www.springframework.org/schema/tx" 7 xmlns:util="http://www.springframework.org/schema/util" 8 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 9 xsi:schemaLocation="http://www.springframework.org/schema/beans 10 http://www.springframework.org/schema/beans/spring-beans-3.2.xsd 11 http://www.springframework.org/schema/context 12 http://www.springframework.org/schema/context/spring-context-3.2.xsd 13 http://www.springframework.org/schema/util 14 http://www.springframework.org/schema/util/spring-util-3.2.xsd 15 http://www.springframework.org/schema/aop 16 http://www.springframework.org/schema/aop/spring-aop-3.2.xsd 17 http://www.springframework.org/schema/tx 18 http://www.springframework.org/schema/tx/spring-tx-3.2.xsd 19 http://www.springframework.org/schema/mvc 20 http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd"> 21 22 23 <!-- 开启包扫描 --> 24 <context:component-scan base-package="com.simon.Controller"/> 25 <!-- 开启mvc注解 --> 26 <mvc:annotation-driven/> 27 28 <!-- 视图解析器 拼接真实路径 在视图名称上添加前缀和后缀--> 29 <bean id="" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 30 <property name="prefix" value="/WEB-INF/"/> 31 <property name="suffix" value=".jsp"/> 32 </bean> 33 34 35 36 </beans>
Mybatis 核心配置sqlMapConfig.xml：
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE configuration 3 PUBLIC "-//mybatis.org//DTD Config 3.0//EN" 4 "http://mybatis.org/dtd/mybatis-3-config.dtd"> 5 <configuration> 6 <!--只需配置缓存，引入第三方缓存插件 --> 7 8 </configuration>
Spring配置文件 applicationContext.xml：【将mybatis框架整合到Spring中】
