Here is the Scheduling Configuration
@Configuration
@EnableScheduling
public class RWInventorySchedule {
protected org.slf4j.Logger log = LoggerFactory.getLogger(RWInventorySchedule.class);
@PersistenceContext
private EntityManager entityManager;
@Bean
public RWInventoryProcessor constructInventoryProcessor() {
log.debug("RWInventorySchedule constructs InventoryProcessor, entityManager : {} " , entityManager);
return new RWInventoryProcessor(entityManager);
}
}
Inventory Processor is the following
public class RWInventoryProcessor {
...
@Scheduled(fixedRate = 5000,initialDelay = 3000)
@Transactional
public void runProcess() {
...
}
}
During execution, getting the following errors in debug log
DEBUG org.springframework.scheduling.annotation.ScheduledAnnotationBeanPostProcessor - Could not find default TaskScheduler bean org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.scheduling.TaskScheduler' available
...
DEBUG org.springframework.scheduling.annotation.ScheduledAnnotationBeanPostProcessor - Could not find default ScheduledExecutorService bean org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'java.util.concurrent.ScheduledExecutorService' available
Am I missing anything
If you're using Java configuration you need an @Bean definition for the type of scheduler you wish to use. Spring does not have a default bean for this. For example
@Bean
public TaskScheduler taskScheduler() {
return new ConcurrentTaskScheduler(); //single threaded by default
}
I have used this form my xml Spring Configuration:
<task:annotation-driven executor="executor" />
<task:scheduler id="scheduler" pool-size="10"/>
<task:executor id="executor" pool-size="7"/>
My Component processor is:
@Component
public class QueueConsumer {
@Autowired
ProcessQueue queue;
@Autowired
TaskProcessor processor;
@Autowired
TaskResultRepository resultRepository;
@Scheduled(fixedDelay = 15000)
public void runJob() {
ProcessTask task = queue.poll();
...
}
}
You need the annotation equivalent to <task:scheduler id="scheduler" pool-size="10"/>
