Why does my Spring Boot App always shutdown immediately after starting

Question

This is my first Spring Boot code  Unfortunately  it always shuts down  I was expecting it to run continuously so that my web client can get some data from the browser   package hello  import org springframework boot    import org springframework boot autoconfigure    import org springframework stereotype    import org springframework web bind annotation      Controller

Maybe it does not fit to your code but i found out if you have a code snippet like this    SpringBootApplication public class SpringBootApacheKafkaApplication        public static void main String   args            SpringApplication run SpringBootApacheKafkaApplication class args  close              then just remove the close   method  That s fixed my problem  Maybe I can help someone with that

If you have a circular spring injected dependency it will fail without warning  depending on the level of logging  and a few other factors  Class A injects Class B  and Class B injects Class A  Via constructor  in this particular case

I had this problem  and in my case it was caused by a simple clumsy mistake  my class had   SpringBootApplication public class MyApplication implements ApplicationRunner    public static void main String   args        SpringApplication run MyApplication class  args      public void run ApplicationArguments args  throws Exception         I removed the  quot implements ApplicationRunner quot  and the run method  which were there due to a copy-paste mistake  and then it worked

in my case i already had the maven dependency to  spring-boot-starter-web  and the project would start fine without auto-stopping when i run it as springboot app from within the IDE  however  when i deploy it to K8s  the app would start and auto-stop immediately  So i modified my main app class to extend SpringBootServletInitializer and this seems to have fixed the auto-stopping    SpringBootApplication public class MyApp extends SpringBootServletInitializer    public static void main String   args    SpringApplication run MyApp class  args

Resolution  the app is not a webapp because it doesn t have an embedded container  e g  Tomcat  on the classpath  Adding one fixed it  If you are using Maven  then add this in pom xml    lt dependency gt       lt groupId gt org springframework boot lt  groupId gt       lt artifactId gt spring-boot-starter-web lt  artifactId gt   lt  dependency gt    For Gradle  build gradle  it looks like  dependencies       compile  org springframework boot spring-boot-starter-web

I think the right answer was at Why does Spring Boot web app close immediately after starting  about the starter-tomcat not being set and if set and running through the IDE  the provided scope should be commented off  Scope doesn t create an issue while running through command  I wonder why   Anyways just added my additional thoughts

If you don t want to make your spring a web application then just add  EnableAsync or  EnableScheduling to your Starter   EnableAsync  SpringBootApplication public class App       public static void main String   args            SpringApplication run App class  args

In my case the problem was introduced when I fixed a static analysis error that the return value of a method was not used   Old working code in my Application java was       public static void main String   args                  SpringApplication run Application class  args           New code that introduced the problem was       public static void main String   args                  try  ConfigurableApplicationContext context              SpringApplication run Application class  args             LOG trace  context      context                   Obviously  the try with resource block will close the context after starting the application which will result in the application exiting with status 0  This was a case where the resource leak error reported by snarqube static analysis should be ignored

I went through the answers here and elsewhere and still had issues   It turned that  like the op   I was running in kubernetes  and the app was fine  but kubernetes had an issue  I forgot to have my app start based on my port environment variable   So  kubernetes helm was telling it to run on 8443 and to liveness probe that  but it was running on some other port  like 8123  from my application properties  The kubernetes events  get events  showed the live-ness probe was failing  so kubernetes was killing the pod app every 30 seconds or so

Here is how you can fix it    Check if you don t have dependency on spring-boot-starter-web in your pom xml file  To get you pom xml file right  use this link start spring io If you have above dependency  but still facing the issue  it is highly possible that your embedded tomcat jars are present   To confirm this  run maven build in debug mode -       mvn spring-boot run --debug   and look for messages like -       WARNING  error reading    Users sparrowmac1  m2 repository org apache tomcat embed tomcat-embed-core 8 5 20 tomcat-embed-core-8 5 20 jar    invalid LOC header  bad signature   WARNING  error reading    Users sparrowmac1  m2 repository com fasterxml jackson core jackson-core 2 8 10 jackson-core-2 8 10 jar    invalid LOC header  bad signature    If such messages are present  purge your local maven repo and try again -      mvn dependency purge-local-repository
