如何实现从一个数据库连接到另一个数据库

ibatis连接数据库的方式是通过下面两个文件实现的：

1.appcontext-common.xml

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">

<property name="driverClassName">

<value>${jdbc.database.driver}</value>

</property>

<property name="url">

<value>${jdbc.database.url}</value>

</property>

<property name="username">

<value>${jdbc.database.username}</value>

</property>

<property name="password">

<value>${jdbc.database.password}</value>

</property>

</bean>

2.appcontext.xml

<bean id="resMonitorDao"

class="com.zltel.zjmonitor.resmonitor.dao.ibatis.ResMonitorDaoImpl"

parent="baseIbatisDao">

</bean>

<bean id="resMonitorService"

class="com.zltel.zjmonitor.resmonitor.service.impl.ResMonitorServiceImpl">

<property name="resMonitorDao">

<ref local="resMonitorDao" />

</property>

</bean>

ibatis查询方法：

private static final String NAMESPACE = "resMonitor."

public List<MonitorType>queryMonitorTypeForList() {

return this.getSqlMapClientTemplate().queryForList(

NAMESPACE + "queryMonitorTypeForList")

}

IBatis连接Oracle连接如下： <transactionManager type="JDBC"> <dataSource type="SIMPLE"> <property name="JDBC.Driver" value="oracle.jdbc.driver.OracleDriver"/> <property name="JDBC.ConnectionURL" value="jdbc:oracle:thin:@localhost:1521:oradb"/> <property name="JDBC.Username" value="用户名"/> <property name="JDBC.Password" value="密码"/> <property name="Pool.MaximumActiveConnections" value="10"/> <property name="Pool.MaximumIdleConnections" value="5"/> <property name="Pool.MaximumCheckoutTime" value="120000"/> <property name="Pool.TimeToWait" value="500"/> <property name="Pool.PingQuery" value="select 1 from ACCOUNT"/> <property name="Pool.PingEnabled" value="false"/> <property name="Pool.PingConnectionsOlderThan" value="1"/> <property name="Pool.PingConnectionsNotUsedFor" value="1"/> </dataSource> </transactionManager>
