I have created one scheduler class
public class TestSchedulderNew {
@Scheduled(fixedDelay = 3000)
public void fixedRateJob1() {
System.out.println("Job 1 running");
}
@Scheduled(fixedDelay = 3000)
public void fixedRateJob2() {
System.out.println("Job 2 running");
}
}
In configuration i have put @ConditionalOnProperty annotation to enable this on conditional purpose.
@Bean
@ConditionalOnProperty(value = "jobs.enabled")
public TestSchedulderNew testSchedulderNew() {
return new TestSchedulderNew();
}
Now in controller, i have created "stopScheduler" method to stop those scheduler , in this controller i have autowired TestSchedulderNew class
@RestController
@RequestMapping("/api")
public class TestCont {
private static final String SCHEDULED_TASKS = "testSchedulderNew";
@Autowired
private ScheduledAnnotationBeanPostProcessor postProcessor; /]
@Autowired
private TestSchedulderNew testSchedulderNew;
@GetMapping(value = "/stopScheduler")
public String stopSchedule(){
postProcessor.postProcessBeforeDestruction(testSchedulderNew,
SCHEDULED_TASKS);
return "OK";
}
}
Now the problem is if conditional property is false then i get below exception
Field testSchedulderNew in com.sbill.app.web.rest.TestCont required a bean of type 'com.sbill.app.schedulerJob.TestSchedulderNew
In case of true everything works fine,
Do we have any option to solve this ?
You can use @Autowired(required=false)
and null check in stopScheduler
method.
@Autowired(required=false)
private TestSchedulderNew testSchedulderNew;
@GetMapping(value = "/stopScheduler")
public String stopSchedule() {
if (testSchedulderNew != null) {
postProcessor.postProcessBeforeDestruction(testSchedulderNew,
SCHEDULED_TASKS);
return "OK";
}
return "NOT_OK";
}
