我试图在连接失败后中止挂起的事务或查询。我通过插入网线来模拟连接失败（wildfly坐在本地，db在远程服务器上）。
我尝试了几种配置，使用验证检查器和两个数据库，oracle：
<valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.oracle.OracleValidConnectionChecker"></valid-connection-checker>
<stale-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.oracle.OracleStaleConnectionChecker"></stale-connection-checker>
<exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.oracle.OracleExceptionSorter"></exception-sorter>
<background-validation>true</background-validation>
<background-validation-millis>5000</background-validation-millis>
和postgresql：
<valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.postgres.PostgreSQLValidConnectionChecker"/>
<check-valid-connection-sql>SELECT 1</check-valid-connection-sql>
<background-validation>true</background-validation>
<background-validation-millis>10000</background-validation-millis>
<exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.postgres.PostgreSQLExceptionSorter"/>
我还尝试设置事务管理器服务，这里收到了一些输出：

我认为获得锁定的问题可能是原因，但不知道如何解决它。我可以添加数据库连接是使用hibernates Session进行的。 Hibernate的版本是5.0.0
我也尝试了查询超时
<timeout>
<query-timeout>60</query-timeout>
</timeout>
令人惊讶的是，它仅在没有连接失败时才有效。 我做错了什么？
