这是我的c3p00l配置

 <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
  <!--  <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
     <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" >  -->
        <property name="driverClass"><value>${jdbc.driverClassName}</value></property>
        <property name="jdbcUrl"><value>${jdbc.url}</value></property>
        <property name="user"><value>${jdbc.username}</value></property>
        <property name="password"><value>${jdbc.password}</value></property>
    </bean>

我如何解决这个问题，这个问题是否与c3pool相关。我使用的是带有默认值的c3pool，是否需要指定任何c3pool属性

最佳答案

Did you try this one?

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
    <property name="driverClass"><value>${jdbc.driverClassName}</value></property>
    <property name="jdbcUrl"><value>${jdbc.url}</value></property>
    <property name="user"><value>${jdbc.username}</value></property>
    <property name="password"><value>${jdbc.password}</value></property>
    <property name="validationQuery" value="SELECT 1"/>
    <property name="testOnBorrow" value="true"/>
</bean>
