负值对 JMS 配置文件中的 TTL 意味着什么?

What does negative value means for TTL in JMS config file?

我有 JMS 的配置文件,我遇到连接问题 pooling.when 我查看了 weblogic 服务器的配置文件,我发现 TTL.could 的负值任何人请解释它的意思。

<queue name="UXFLogQueue">
    <sub-deployment-name>application</sub-deployment-name>
    <delivery-params-overrides>
      <delivery-mode>Persistent</delivery-mode>
      <time-to-live>-1</time-to-live>
      <priority>-1</priority>
      <redelivery-delay>-1</redelivery-delay>
    </delivery-params-overrides>
    <delivery-failure-params>
      <redelivery-limit>1</redelivery-limit>
    </delivery-failure-params>
    <jndi-name>UXFLogQueue</jndi-name>
  </queue>

"If no JMS template is specified for this destination, then -1 means that the destination will not override the TimeToLive setting. Otherwise, -1 means that the value comes from the template."
