自动恢复Wildfly 8.2 for Oracle中的连接，而不使用匹配时验证

Question

我正在使用wildfly 8.2和oracle 11g，如果可能的话，我让我的连接池刷新一个无效的连接并创建一个新的连接。我在后端也使用了Spring和Hibernate (我们正在通过JNDI查找连接)

我在网上找不到一个简洁的oracle池配置示例，所以我从各种来源抄袭了一些东西，并设法让它正常工作。

我的问题是。我将"Validate On Match“设置为true，但是Jboss文档(https://docs.jboss.org/jbossas/docs/Server_Configuration_Guide/beta500/html/ch13s13.html)声明

​

<validate-on-match> - Prior to JBoss 4.0.5, connection validation occurred when the JCA layer attempted to match a managed connection. With the addition of <background-validation> this is no longer required. Specifying <validate-on-match> forces the old behavior. NOTE: this is typically NOT used in conjunction with <background-validation>

​

如果我能避免的话，我不想使用“旧行为”。谁有使用Oracle 11g Wildfly 8.2自动恢复连接池的示例。并使用ojdbc6驱动程序。

谢谢

顺便说一下，我当前的池设置如下(nb我知道我将池大小设置为1，这样我就可以轻松地终止会话并知道池恢复)。

尝试此validation节点：

<validation>
    <background-validation>true</background-validation>
    <background-validation-millis>200000</background-validation-millis>
    <check-valid-connection-sql>select 1 from dual</check-valid-connection-sql>
</validation>

记住要调整background-validation-millis的值。
