**dao层配置文件主要做数据库相关的配置.**  
文件名:applicationContext-dao.xml

<?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:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    	
    	<context:property-placeholder location="classpath:db.properties"/>
    
    	
    	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
    		<property name="driverClass" value="${jdbc.driver}"/>
    		<property name="jdbcUrl" value="${jdbc.url}"/>
    		<property name="user" value="${jdbc.username}"/>
    		<property name="password" value="${jdbc.password}"/>
    	</bean>
    
    	
    	
    	
    	
    	
    	
    	
    	
    	
    
    	
    	<bean class="org.mybatis.spring.SqlSessionFactoryBean" id="sqlSessionFactory">
    		<property name="dataSource" ref="dataSource"/>
    		<property name="configLocation" value="classpath:SqlMapperClient.xml"/>
    		<property name="typeAliasesPackage" value="com.csdn.pojo" />
    	</bean>
    	
    	
    
    
    		<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    			<property name="basePackage" value="com.csdn.mapper"/>
    			
    		</bean>
    
    </beans>

## 附上properties文件: ##

jdbc.driver=com.mysql.jdbc.Driver
    jdbc.url=jdbc:mysql://localhost:3306/mysql505?characterEncoding=utf-8
    jdbc.username=root
    jdbc.password=root
