Class WrappingSimonDataSource

java.lang.Object

org.javasimon.jdbcx4.AbstractSimonDataSource

org.javasimon.jdbcx4.WrappingSimonDataSource

All Implemented Interfaces:

Wrapper, CommonDataSource, DataSource

public class WrappingSimonDataSource
extends AbstractSimonDataSource
implements DataSource

WrappingSimonDataSource allows to wrap existing datasource instead of providing the Driver and URL information. For example - it can be used with Spring easily:

<bean id="dataSource" class="org.javasimon.jdbcx.WrappingSimonDataSource">
     <property name="dataSource" ref="pooledDataSource"/>
     <property name="prefix" value="sky.batchpricer.skydb"/>
 </bean>

 <bean id="pooledDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
     <property name="driverClassName" value="my.driver.class.Driver"/>
     <property name="url" value="${mydb.url}"/>
     <property name="initialSize" value="0"/>
     <property name="maxActive" value="5"/>
     <property name="maxIdle" value="2"/>
     <property name="validationQuery" value="SELECT 1"/>
 </bean>
