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

<property name="locations">

<value>classpath:jdbc.properties</value>
</list>
</property>
</bean>

<!-- c3p0数据源配置方式-->
<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}"
/>
