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：
