问题可能是因为IBM MQ不支持较高版本，或者与Spring 6不兼容，但不确定。正在寻找解决此问题的方法。

MQ提供与Jakarta兼容的软件包。您需要更改您的依赖项以使用正确的模块。
如果您正在使用MQ Spring Boot库，请使用相应的V3.x.x构件。
如果您直接引用MQ客户端库，请改用com.ibm.mq.jakarta.client，而不是com.ibm.mq.allclient。
英文:
MQ provides Jakarta-compatible packages. You have to change your dependencies to use the correct module.
If you're using the MQ Spring Boot library, then use the corresponding V3.x.x artifact.
If you are directly referencing the MQ client libraries, then use com.ibm.mq.jakarta.client instead of the com.ibm.mq.allclient.
