Question

The log information before stopping is as follows:

2017-12-26 15:12:10.857  INFO 10878 --- [       Thread-3]   ationConfigEmbeddedWebApplicationContext : Closing org.springframework.boot.context.embedded.AnnotationConfigEmbeddedWebApplicationContext@64a294a6: startup date [Tue Dec 26 14:53:02 CST 2017];  root of context hierarchy
 2017-12-26 15:12:10.860  INFO 10878 --- [       Thread-3] o.s.j.e.a.AnnotationMBeanExporter        : Unregistering JMX-exposed beans on shutdown
 2017-12-26 15:12:10.867  INFO 10878 --- [       Thread-3] org.mongodb.driver.connection            : Closed connection [connectionId{localValue:2,   serverValue:26574}] to  120.25.224.11:28888 because the pool has been closed.

I used mongodb and redis databases, built-in tomcat
What is the reason? How should we solve it?
Thank you

Answer 1

These are not the reasons. They look more like the results of the shutdown. Look up again to see if there are any other related log outputs.
