Application is not stopped with missingTopicFatal and manually started listeners - spring

Question

I'm using spring and spring-kafka.
When the application starts, I'm loading compacted topics into memory then when the topics are fully read, the application is started.
In order to do that I created #KafkaListeners with autostartup to false and a SmartLifeCycle bean with AbstractMessageListenerContainer.DEFAULT_PHASE - 1 phase which is doing listener.start() on all those listeners (which read compacted topics) then wait for them to be finished.
This is working great but if I set spring.kafka.listener.missing-topics-fatal = true with a missing topic, there is an error :
org.springframework.context.ApplicationContextException: Failed to start bean 'org.springframework.kafka.config.internalKafkaListenerEndpointRegistry'; nested exception is java.lang.IllegalStateException: Topic(s) [mytopic] is/are not present and missingTopicsFatal is true
It's the expected behavior, but the application is not shutdown, my manually started listeners keeps running and sending errors :
java.lang.IllegalStateException: org.springframework.context.annotation.AnnotationConfigApplicationContext#502e1410 has not been refreshed yet
How can I make the application exit in this case ?

Answer 1

Catch the exception and shut down the JVM:
#SpringBootApplication
public class So60036945Application {
public static void main(String[] args) {
try {
SpringApplication.run(So60036945Application.class, args);
}
catch (ApplicationContextException ace) {
if (ace.getCause() instanceof IllegalStateException) {
ace.printStackTrace();
System.exit(1);
}
}
}
#KafkaListener(id = "so60036945", topics = "so60036945a")
public void listen(String in) {
System.out.println(in);
}
}
But, as I said in Gitter, it's better to auto-start the compacted topic listeners and start the other listeners manually (the other way around to what you are doing now).
