SSi(spring+struts_ibatis)多数据库连接解决方案

1。创建配置文件 jdbc.properties

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://192.168.99.100/infodata?useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&transformedBitIsBoolean=true
jdbc.username=root
jdbc.password=root
jdbc2.driverClassName=com.mysql.jdbc.Driver
jdbc2.url=jdbc:mysql://192.168.99.101/data1?useUnicode=true&characterEncoding=utf-8
jdbc2.username=root
jdbc2.password=root
jdbc3.driverClassName=com.mysql.jdbc.Driver
jdbc3.url=jdbc:mysql://192.168.99.102/data2?useUnicode=true&characterEncoding=utf-8
jdbc3.username=root
jdbc3.password=root 

2。在spring配置文件中写入

<?xml version="1.0" encoding="UTF-8"?>

 3。导入两个jar包：

c3p0-0.9.1.2.jar
commons-pool.jar
commons-dbcp.jar
