Question

I am trying to use Quartz 2.2.1 with spring boot. Im trying to declare a scheduled task that is supposed to write some datas into a file. My Job is defined like below :

Answer 1

Spring Boot manages it for you. Remove the quartz dependency and just create a Service for having scheduled executions:

@Service
public class JobScheduler{

    @Autowired
    JobController controller;

    //Executes each 5000 ms
    @Scheduled(fixedRate=5000)
    public void performJob() {
        controller.doPrintData();
    }
}

And enable the task scheduling for your application:

@SpringBootApplication
@EnableScheduling
public class Application {

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class);
    }
}
