============ 数据库名可以这样指定 ==============

Xml代码

1. <property name="connection.url">  
2.     jdbc:sqlserver://localhost:1433;DatabaseName=supermarket  
3. </property>  

<property name="connection.url"> jdbc:sqlserver://localhost:1433;DatabaseName=supermarket </property>

==============URL 还可以传参数===================

Xml代码

1. <property name="connection.driver_class">org.gjt.mm.mysql.Driver</property>  
2. <property name="connection.url">  
3. jdbc:mysql://localhost:3306/struts?useUnicode=true&characterEncoding=GBK  
4. </property>  

<property name="connection.driver_class">org.gjt.mm.mysql.Driver</property> <property name="connection.url"> jdbc:mysql://localhost:3306/struts?useUnicode=true&characterEncoding=GBK </property>
目前，proxool用法，被大部分人认为是最优秀的。

就可以监控到连接池的状况了！
