[help] c3p0:JDBC driver, cannot unregister when the Web application stops. To prevent memory leaks, the JDBC driver has been forcibly logged out.

using JDBCDataSouce is normal, startup and stop are normal, and no error is reported.
when switching to C3P0

configuration in C3P0 XML:

<!-- -->
<bean id="dataSource_c3p0_properties"
 class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
    <property name="driverClass" value="${jdbc.driver}"/>
    <property name="jdbcUrl" value="${jdbc.url}"/>
    <property name="user" value="${jdbc.username}"/>
    <property name="password" value="${jdbc.password}"/>
</bean>

I don"t know how to solve it. The online materials say that I want to cancel the registration, but that"s all JAVA programs.
