我构建了一个应用程序并在本地部署...它工作得很完美。我将其部署在远程服务器上，并开始获取主题行中提到的异常。这不是因为任何防火墙问题。

我将hibernate.xml更改为通过IP地址连接，而不是本地主机，现在我在本地部署的应用程序上获得了相同的超时。当我让应用程序运行超过一天时，我得到这个错误。

我自己在提交事务或关闭会话后不会执行任何操作。我在hibernate.cfg.xml中使用以下属性

<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://myremotehost:3306/akp</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.connection.password">root</property>
        <property name="hibernate.show_sql">false</property>
        <property name="hibernate.current_session_context_class">thread</property>
        <property name="hibernate.query.factory_class">org.hibernate.hql.ast.ASTQueryTranslatorFactory</property>

原因: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException:驱动程序隐式关闭connection closed.Connection后不允许执行任何操作。

You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.

Caused by: java.net.SocketException: Software caused connection abort: socket write error

有没有人知道可能导致这种行为的原因？

编辑:现在我在我的hibernate.cfg.xml file.Is中使用了folloing，对吗？
