Spring - @PostConstruct method called two times
Question
Here is my Spring Controller class
@Controller
public class SchedularController{
@Autowired
ProjectRepository projectRepository;
@Autowired
UtilityRepository utilityRepository;
@PostConstruct
public void postconstruct(){
System.out.println("Starting schedular...");
}
}
Problem is when I start server postconstruct method runs two times.
I have checked another posts on this which mostly says - "That can happen if you have multiple frameworks managing the same bean class. Eg JSF and CDI, or JSF and Spring, or CDI and Spring, etc."
But I am not using JSF or CDI and still having this problem.(and my @PostConstruct method is in controller class)
How to resolve this?
Edit -
Here is my pom file

I was also facing the same problem few days back and I have successfully solve this issue.
In my case I have created application using Spring starter .
When you import project in Eclipse or any IDE you saw there is two classes in main package:
ServletInitializer.java which extends
SpringBootServletInitializerand overridesconfigure(), it gets called when we create war file and run under tomcat serverYourApplication.java contains
main()which is entry point to our application if run/debug application on local server.
I have referred to this to create war file and do necessary change.
Problem was I forgot to remove ServletInitializer.java which also contains the same method, this was the main cause of getting initialising twice.
Once you remove the extra code from that file, Spring Boot will only initialise your context once and will able to execute your code once.
