Spring Boot 3.2 automatically change log level during shutdown

Question

We recently upgraded springBoot version to 3.2, and Java 21 64 bit. We observed wired behaviour while shutting down spring boot application , log level automatically change INFO to ERROR, and we are not getting expected log messages.

After so many research, we found there is a feature "automatic log level propagation".

We have some important INFO messages that should appear during application off.

We tried to disable with few properties like : management.tracing.enabled = false spring.main.log-shutdown-info = true

But nothing help, it is still ERROR.

Please suggest and help what we can do to get INFO level at end of application.

We need INFO log level while spring boot application is shutting down.

As per Shutdown Log when run the application with argument -Dlog4j2.debug : TRACE StatusLogger [AsyncContext@25bbe1b6] AsyncLoggerDisruptor: disruptor has been shut down :

Answer 1

The problem you are having is due to the ordering between application listeners: the LoggingApplicationListener has a very high precedence of:

Ordered.HIGHEST_PRECEDENCE + 20

This means that the listener is called pretty early at startup, but unless I am mistaken Spring calls listeners in the same order at shutdown.

If your shutdown listener requires logging, it should have a precedence between Ordered.HIGHEST_PRECEDENCE and Ordered.HIGHEST_PRECEDENCE + 19. Specifying the order can be done either by implementing Ordered or using the @Order annotation.
