BoneCP在工作中自动关闭

Question

我们有一个Oracle 11g数据库，一个使用休眠的Web服务。我们最近切换到BoneCP进行连接池，但似乎有些问题，BoneCP在软件启动过程中关闭。

这里是hibernate.cfg文件：

<hibernate-configuration> 
<session-factory> 
    <property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property> 
    <property name="hibernate.connection.password">pass</property> 
    <property name="hibernate.connection.url">url/property> 
    <property name="hibernate.connection.username">user</property> 
    <property name="hibernate.default_schema">SYSTEM</property> 
    <property name="hibernate.dialect">org.hibernate.dialect.OracleDialect</property> 
    <property name="hibernate.connection.defaultNChar">true</property> 
    <property name="hibernate.connection.writedelay">0</property> 
    <property name="hbm2ddl.auto">update</property> 
    <property name="show_sql">true</property> 

    <property name="bonecp.partitionCount">1</property> 
    <property name="bonecp.maxConnectionsPerPartition">45</property> 
    <property name="bonecp.minConnectionsPerPartition">10</property> 
    <property name="bonecp.acquireIncrement">10</property> 
    <property name="bonecp.idleConnectionTestPeriodInMinutes">1</property> 
    <property name="bonecp.idleMaxAgeInMinutes">10</property> 
    <property name="bonecp.idleConnectionTestPeriod">60</property> 
    <property name="bonecp.poolAvailabilityThreshold">5</property> 
    <property name="bonecp.partitionCount">1</property> 
    <property name="bonecp.acquireIncrement">3</property> 
    <property name="bonecp.releaseHelperThreads">3</property> 
    <property name="bonecp.connectionTestStatement">SELECT 1</property> 
    <property name="connection.provider_class">com.jolbox.bonecp.provider.BoneCPConnectionProvider</property> 
</session-factory> 
</hibernate-configuration> 

在软件的启动，三个查询将被执行，但是第三个查询获取要执行的机会前，BoneCP似乎被关闭，这条线在日志文件：

SEVERE: [http-thread-pool-8080(5)] INFO com.jolbox.bonecp.BoneCP - Shutting down connection pool... 

下面是相关的堆栈跟踪：

这意味着池下方被明确调用shutdown所以你各层的问题不在于此。
