如果是在Spring中使用DBCP连接池，在定义datasource增加属性

validationQuery

和

testOnBorrow

<bean id="vrsRankDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="${jdbc.driverClassName}" />
<property name="url" value="${countNew.jdbc.url}" />
<property name="username" value="${countNew.jdbc.user}" />
<property name="password" value="${countNew.jdbc.pwd}" />
<property name="validationQuery" value="SELECT 1" />
<property name="testOnBorrow" value="true"/>
</bean>

如果是在Spring中使用c3p0连接池，则在定义datasource的时候，添加属性

testConnectionOnCheckin

和

testConnectionOnCheckout

<bean name="cacheCloudDB" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driver}"/>
<property name="jdbcUrl" value="${cache.url}"/>
<property name="user" value="${cache.user}"/>
<property name="password" value="${cache.password}"/>
<property name="initialPoolSize" value="10"/>
<property name="maxPoolSize" value="${cache.maxPoolSize}"/>
<property name="testConnectionOnCheckin" value="false"/>
<property name="testConnectionOnCheckout" value="true"/>
<property name="preferredTestQuery" value="SELECT 1"/>
