您将kafkaTopicPattern设置为-

You are getting kafkaTopicPattern as -

@Qualifier("kafkaTopicPattern")
private String kafkaTopicPattern;

我看到您正在更新--

this.kafkaTopicPattern = "new-topic-pattern";

但是，如果这两个实例位于不同的实例对象中，则不会刷新注入到侦听器中的"kafkaTopicPattern"的原始值.因此，您必须确保使用新的模式刷新侦听器对象.

But the original value for "kafkaTopicPattern" which is injected in listener wont be refreshed by this if these 2 are in different instance objects. So you will have to make sure that the listener objects are refreshed with the new pattern.
