I have a job application (to be run as an outside cron in EKS, not a cron within this Spring Boot app itself) which needs to terminate. I run it in Eclipse as Application.java -> Run, and when it's done, it does not terminate (similar to a Web app).
But when I do this manually at the end of my run()
:
@SpringBootApplication
public class MyApplication implements CommandLineRunner {
@Autowired
private ApplicationContext appContext;
@Override
public void run(String... args) throws Exception {
// ... Run job, and at the end terminate manually
SpringApplication.exit(appContext, new ExitCodeGenerator() {
@Override
public int getExitCode() {
return 0;
}
});
I get this error:

Is there a way to remove the Tomcat layer from this Spring Boot job app and have it terminate manually?
I found the solution: just remove from Pom.xml the spring-boot-starter-web dependency, per this thread.
<!-- Removed
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
-->
This automatically removes the embedded Tomcat. In fact, I don't even need to do SpringApplication.exit()
anymore, I got rid of that extra code. Now the job immediately terminates on completion.
