我有一个使用c3p0 0.9.1.2,hibernate 3.2.1.ga和spring 2.5.5.问题是数据库连接没有自行关闭.这是日志:

[22 mars 2012 12:29:56,091] DEBUG com.mchange.v2.resourcepool.BasicResourcePool ["http-apr-8080"-exec-4]获取测试池已经达到最大值.[管理:20; max:20] [22 mars 2012 12:29:56,091] DEBUG com.mchange.v2.resourcepool.BasicResourcePool ["http-apr-8080"-exec-4] awaitAvailable():com.mchange.v2.c3p0.impl .NewPooledConnection @ 15cc604 [22 mars 2012 12:29:56,091] DEBUG com.mchange.v2.resourcepool.BasicResourcePool ["http-apr-8080"-exec-4] trace com.mchange.v2.resourcepool.BasicResourcePool@6b0524 [托管:20,未使用:0,排除:0](例如com.mchange.v2.c3p0.impl.NewPooledConnection@15cc604)

这是数据源配置:

<!-- Local DataSource that works in any environment -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
    <property name="driverClass" value="${database.driver}"/>
    <property name="jdbcUrl" value="${database.url}"/>
    <property name="user" value="${database.user}"/>
