oracle - BoneCP 在工作中自动关闭

Question

我们有一个 Oracle 11g 数据库，一个使用 hibernate 的 Web 服务。我们最近改用 BoneCP 进行连接池，但似乎出了点问题，BoneCP 在软件启动过程中关闭了。

这是 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> 

在软件启动时，会执行三个查询，但在第三个查询有机会执行之前，BoneCP 似乎已关闭，日志文件中包含以下行:

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

这是相关的堆栈跟踪:

我们使用的是bonecp-0.7.1.RELEASE.jar、bonecp-provider-0.7.1.RELEASE.jar 和 guava-14.0.1.jar。

这意味着池下面的层显式调用关闭，因此您的问题出在其他地方。
