About running springboot times unregistering jmx-exposed beans on shutdown solutions

In fact, this error does not affect the operation of the program, but for Virgo's colleagues, see the error is inevitably uncomfortable, then look at the solution, this error message means: In the shutdown state is not registered JMX exposed beans.

The solution is to add annotations to the @EnableMBeanExport (registration = registrationpolicy.ignore_existing) on the Ingress class

As for the reason, personal understanding is because: because springboot inside in order to see the performance of each bean, so monitoring each bean,jmx is background monitoring, if you want to receive the bean, it is necessary to register, and JMX detects that there are registered or re-registered beans will report this error
