HikariCP陷入空闲连接

Question

使用HiknateCP和hibernate 5.1.0.Final执行应用程序时遇到问题。在以下日志条目中可以看到连接似乎停留在空闲状态的某个时刻：

2017-08-04 11:13:28 [TreasyPool管家] DEBUG com.zaxxer.hikari.pool.HikariPool - TreasyPool - 池统计数据（总数= 10，活跃= 0，空闲= 10，等待= 0）< / p>

关于在HikariCP中保持连接处于空闲状态所需条件的任何想法？它发生在使用arquillian执行集成测试期间。 persistence.xml包含HikariCP配置参数，如下所示：

    

    <property name="hibernate.current_session_context_class">thread</property>

    <!-- Alterado para compatibilidade do hibernate5 -->
    <property name="hibernate.id.new_generator_mappings">false</property>

    <!-- Second-Level Cache -->

    <property name="net.sf.ehcache.configurationResourceName">/ehcache.xml</property>
    <property name="hibernate.generate_statistics">false</property>

</session-factory>

亲切的问候。
