Question

我有一个Spring应用程序，该应用程序使用JMS Solace连接到具有多个订阅的Solace代理。每个订阅都有一个不同的msgVPN和队列值。我能够使用solace-jms-spring-boot-starter创建与一个队列的连接。问题是，当我尝试在同一连接上创建第二个队列时，出现Solace 503错误“未知队列”错误。

理想情况下，我想要一个JMS连接和几个队列，以从所有订阅中检索消息。 Solace可以做到这一点吗，还是我还需要另一种方式？

当前，这就是我试图建立连接的方式。

我发现JMS Solace中每个连接只能有一个队列。因此，如果您需要多个连接，则可以使用不同的登录值创建另一个Connection bean（例如，公共Connection connection2（））。

我必须将solConnectionFactory（）折叠到我的连接方法中以具有不同的值，但是它现在可以正常工作。

无法在同一连接上使用不同的msgVPN连接到多个Solace队列
