我有一个小型的spring-boot应用程序，该应用程序连接到ActiveMQ上的一个或多个主题，这些主题在启动时在应用程序的application.properties文件中设置-然后将这些消息发送到数据库。

这一切都很好，但是在尝试实施故障转移时遇到一些问题-基本上，应用程序将尝试重新连接，但是在重试一定次数后，应用程序进程将自动退出，从而防止重试(理想情况下，我希望该应用程序能够永久重试，直到被手动终止或ActiveMQ再次可用为止。我尝试将连接URL(使用application.properties中的maxReconnectAttempts)中的连接选项(例如url.options)显式设置为-1/0/99999，但这些都似乎不正确，因为行为是相同的每一次。通过查看有关Apache's own reference page的建议，我也希望该行为也可以作为默认行为。

[如果有人有任何建议强制不要退出该应用程序，我将非常感谢！我认为很重要的代码如下：@Configuration

public class AmqConfig {

private static final Logger LOG = LogManager.getLogger(AmqConfig.class);
