Question

问题陈述：

我们在开发队列管理器（USTCMN01）上设置了2个主题

一个用于我们的开发用途（EDM.BIRS.RDP.ONEPPM.TO_RDA），另一个用于SIT（EDM.BIRS.RDP.S1.ONEPPM.TO_RDA）

发布到我们的SIT主题时，我们的消费者队列（EDM.BIRS.RDP.S1.RDA.FROM_ONEPPM）没有在另一端收到消息。在制作信息时我们没有得到任何例外。

问题：

当我们尝试在Java客户端中查找SIT主题时，尽管我们正在提供专用于SIT的目的地，但它正在解析为DEV主题。

Answer 1

这段代码：

String destinationStr = "EDM.BIRS.RDP.S1.ONEPPM.TO_RDA";

Destination destination;
try {
    destination = (Destination) ic.lookup("cn=" + destinationStr);

从JNDI查找JMS Destination对象;在这种情况下，您已将其配置为LDAP支持的JNDI。请注意，提供的名称是正在使用的查找名称或队列索引Java对象。返回的实际Destination将控制控制该LDAP / JNDI服务器的任何人。

对目标对象执行.toString（）并查看要解析的内容。这实际上就是发送消息的地方。

请注意，从JNDI查找对象所提供的名称不是要使用的队列或主题的实际名称。

Answer 2

问题是由于LDAP服务器中的外部配置不匹配导致返回的目标值不同。

IBM MQ主题查找始终返回默认目标
