关于Spring、SpringMVC、Mybatis框架的整合  
1.首先在工程中建立一个Dynamic Web 或者Maven工程  
2.引入相关的jar包  
2.1一共是3个配置文件：SpringContext.xml、Springmvc.xml、SqlMapConfig.xml  
3.配置applicationContext.xml文件：  
3.1一开始配置相应的schema检测（这里可以根据自己情况增加，并不是说就这些）

3.2配置jdbc属性文件：  
` <context:property-placeholder location="classpath:jdbc.properties" />`

3.3封装数据源：

这里的数据池我用了阿里的Druid

3.4配置SqlSessionFactory:

<bean class="org.mybatis.spring.SqlSessionFactoryBean">
    		
    		<property name="configLocation" value="classpath:SqlMapConfig.xml" />
    		
    		<property name="dataSource" ref="dataSource" />
    		
    		<property name="typeAliasesPackage" value="com.wzu.crm.pojo"></property>
    	</bean>

这其中的Mybatis全局配置文件我取名是“SqlMapConfig.xml”

3.5Mapper包的扫描：

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    		
    		<property name="basePackage" value="com.wzu.crm.mapper" />
    	</bean>

3.6Service包的扫描：

<context:component-scan base-package="com.wzu.crm.service"></context:component-scan>

3.7有关事务的部分：配置事务管理器：

<bean id="transactionManager"	class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    		
    		<property name="dataSource" ref="dataSource" />
    	</bean>
    
    	
    	<tx:advice id="txAdvice" transaction-manager="transactionManager">
    		<tx:attributes>
    			
    			<tx:method name="save*" propagation="REQUIRED" />
    			<tx:method name="insert*" propagation="REQUIRED" />
    			<tx:method name="add*" propagation="REQUIRED" />
    			<tx:method name="create*" propagation="REQUIRED" />
    			<tx:method name="delete*" propagation="REQUIRED" />
    			<tx:method name="update*" propagation="REQUIRED" />
    			<tx:method name="find*" propagation="SUPPORTS" read-only="true" />
    			<tx:method name="select*" propagation="SUPPORTS" read-only="true" />
    			<tx:method name="get*" propagation="SUPPORTS" read-only="true" />
    			<tx:method name="query*" propagation="SUPPORTS" read-only="true" />
    		</tx:attributes>
    	</tx:advice>

3.8 配置AOP切面：

<aop:config>
    		<aop:advisor advice-ref="txAdvice"
    			pointcut="execution(* com.wzu.crm.service.*.*(..))" />
    	</aop:config>

4.到这里的话完整的Spring配置文件已经配好，接下来是SpringMvc.xml

4.1:SpringMvc内容较少：

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
    	xmlns:context="http://www.springframework.org/schema/context"
    	xmlns:mvc="http://www.springframework.org/schema/mvc"
    	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
            http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">
    	
    	<context:component-scan base-package="com.wzu.crm.controller" />
      
        <context:property-placeholder   location="classpath:crm.properties"/>
    	
    	<mvc:annotation-driven></mvc:annotation-driven>	
    	
    	<bean	class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    		
    		<property name="prefix" value="/WEB-INF/jsp/" />
    		
    		<property name="suffix" value=".jsp" />
    	</bean>
    </beans>

5.Mybatis的全局配置文件SqlMapConfig.xml:

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
    "http://mybatis.org/dtd/mybatis-3-config.dtd">
    <configuration>
    
    </configuration>

6.还需要在WEB.xml中配置相关内容：

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
      </context-param>
      
      
      <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
      
      
      <filter>
        <filter-name>encoding</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
      </filter>
      <filter-mapping>
        <filter-name>encoding</filter-name>
        <url-pattern>/*</url-pattern>
      </filter-mapping>
      
      
      <servlet>
        <servlet-name>CRM</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:springmvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
      </servlet>
      <servlet-mapping>
        <servlet-name>CRM</servlet-name>
        <url-pattern>*.action</url-pattern>
      </servlet-mapping>

配置到这里就已经完成了：只需要改动配置文件中的包名就行！然后按照正常的开发步骤做下去即可：Pojo——Mapper——Service——Serviceimpl——Controller

PS：在开发过程中applicationContext.xml可能会变得很多，你也可以按照功能的区别将其拆分成：1.applicationContext-dao.xml 2.applicationContext-service.xml 3.applicationContext-tran.xml
