内容：spring读取jdbc.properties的配置信息；

**一.jdbc.properties的配置信息**

jdbc.properties的配置信息主要包括用户名、密码以及连接池的一些配置，代码如下：

jdbc.driverClassName=com.mysql.jdbc.Driver
    #jdbc.url=jdbc\:mysql\://172.18.73.253\:3307/network
    jdbc.url=jdbc\:mysql\://127.0.0.1\:3306/webwork
    #jdbc.url=jdbc\:mysql\://172.18.73.5\:3306/webwork
    jdbc.username=root
    jdbc.password=root
    jdbc.initialPoolSize=20  
    jdbc.maxPoolSize=100  
    jdbc.minPoolSize=10  
    jdbc.maxIdleTime=600  
    jdbc.acquireIncrement=5  
    jdbc.maxStatements=50
    jdbc.idleConnectionTestPeriod=60

二、 在applicationContext.xml中怎么读取jdbc.properties的配置信息；

废话少说，直接上代码，代码如下：

<?xml version="1.0" encoding="UTF-8"?>
    <beans
    	xmlns="http://www.springframework.org/schema/beans"
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            <property name="locations">  
               <list>  
                     <value>classpath:jdbc.properties</value>  
               </list>  
            </property>  
         </bean>  
         
         
         <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
    		destroy-method="close"
    		p:driverClass="${jdbc.driverClassName}"
    		p:jdbcUrl="${jdbc.url}"
    		p:user="${jdbc.username}"
    		p:password="${jdbc.password}"
    		p:maxPoolSize="${jdbc.maxPoolSize}"
    		p:minPoolSize="${jdbc.minPoolSize}"
    		p:initialPoolSize="${jdbc.initialPoolSize}"
    		p:maxIdleTime="${jdbc.maxIdleTime}"
    		p:acquireIncrement="${jdbc.acquireIncrement}"
    		p:maxStatements="${jdbc.maxStatements}"
    		p:idleConnectionTestPeriod="${jdbc.idleConnectionTestPeriod}"
    	 />
