Здесь WebConfig.java:

@Configuration 
@EnableScheduling 
@EnableWebMvc 
@ComponentScan(basePackages="com.project") 
public class WebConfig implements SchedulingConfigurer 
{  
protected static final Logger slf4jLogger = Logger.getLogger(WebConfig.class.getName()); 
private static final String cronExpression = "0 0 * * * ?"; 



/*@Bean 
public MobileNotifSchedulerBean schedulerbean() 
{ 
    return new MobileNotifSchedulerBean(); 
}*/ 

@Bean 
public InternalResourceViewResolver getInternalResourceViewResolver() 
{ 
    InternalResourceViewResolver resolver = new InternalResourceViewResolver(); 
    resolver.setPrefix("/WEB-INF/jsp/"); 
    resolver.setSuffix(".jsp"); 
    resolver.setSuffix(".html"); 
    resolver.setSuffix(".htm"); 
    return resolver; 
} 

@Bean 
CronTrigger cronTrigger() 
{ 
    //String timeZone = "Asia/Calcutta"; 

    String timeZone = null; 
    HashSet<String> userTimeZonesfromDB = FetchUserTimeZones.fetchUserTimeZone(); 
    for (String s : userTimeZonesfromDB) 
    { 
     timeZone = s; 
     slf4jLogger.info(s); 
    } 
    return new CronTrigger(cronExpression, TimeZone.getTimeZone(timeZone)); 
} 


@Override 
public void configureTasks(ScheduledTaskRegistrar taskRegistrar) 
{ 

    taskRegistrar.addCronTask(new CronTask(new MobileNotifSchedulerBean(), cronTrigger())); 
} 

@Bean(destroyMethod="shutdown") 
public Executor taskExecutor() 
{ 
    return Executors.newScheduledThreadPool(1); 
} 
} 

Вот мой MobileNotifSchedulerBean:

@EnableScheduling 
public class MobileNotifSchedulerBean implements Runnable 
{ 
protected static final Logger slf4jLogger = Logger.getLogger(MobileNotifSchedulerBean.class.getName()); 


public void sendQuestionNotif() 
{ 
    try 
    { 
     HashSet<String> reg_ids = FetchRegistrationIDs.fetchItems(); 
     for (String s : reg_ids) 
     { 
      String REGISTRATION_IDs = s; 
      slf4jLogger.info(s);     
      MobileSNSPushNotification.sendNotification(REGISTRATION_IDs); 
     } 
    } 
    catch (IOException e) 
    { 
     //e.printStackTrace(); 
     slf4jLogger.error(e); 
     slf4jLogger.error(e.getMessage()); 
     slf4jLogger.error(e.getStackTrace()); 
    } 
} 


@Override 
public void run() 
{ 
    sendQuestionNotif(); 
} 
} 

Я использую Java 8 и Spring MVC 4. Я хочу, чтобы решить эту ошибку «Нет квалификационная рожкового типа [org.springframework.scheduling.TaskScheduler] определяется « любезно помогите мне. ТИА.

Answer 1

Обозначает MobileNotifSchedulerBean@Configurable. Я думаю, это сработает.

Answer 2

Это исключение регистрируется от org.springframework.scheduling.annotation.ScheduledAnnotationBeanPostProcessor.inishRegistration():

if (this.registrar.hasTasks() && this.registrar.getScheduler() == null) { 
    Assert.state(this.beanFactory != null, "BeanFactory must be set to find scheduler by type"); 
    try { 
     // Search for TaskScheduler bean... 
     this.registrar.setTaskScheduler(this.beanFactory.getBean(TaskScheduler.class)); 
    } 
    catch (NoSuchBeanDefinitionException ex) { 
     logger.debug("Could not find default TaskScheduler bean", ex); 
     // Search for ScheduledExecutorService bean next... 
     try { 
      this.registrar.setScheduler(this.beanFactory.getBean(ScheduledExecutorService.class)); 
     } 
     catch (NoSuchBeanDefinitionException ex2) { 
      logger.debug("Could not find default ScheduledExecutorService bean", ex); 
      // Giving up -> falling back to default scheduler within the registrar... 
     } 
    } 
} 

Этот процесс пытается установить планировщик задач для регистратора. Для этого, он пытается найти зарегистрированный планировщик боб через BeanFactory.getBean метода:

1. пытается найти сконфигурированный TaskScheduler боба, если не найден, то откаты to->
2. найти ScheduledExecutorService боб, если не найден, то откаты to->
3. с помощью планировщика в по умолчанию в регистраторе (то же самое указано в коде выше комментарий: // Бросаю -> отступая по умолчанию планировщиком в регистраторе ...)

Если какой-либо из TaskScheduler или ScheduledExecutorService бина не найден в контейнере, BeanFactory.getBean бросает исключение.

ScheduledAnnotationBeanPostProcessor в свою очередь, регистрирует эти исключения с уровнем DEBUG:

logger.debug("Could not find default TaskScheduler bean", ex); 
logger.debug("Could not find default ScheduledExecutorService bean", ex); 

Итак, в заключение эти исключения только вошли в процессе поиска запасной вариант для планировщика задач боба, и они не влияют на выполнение приложение.

Уровень логарифм этого класса может быть повышен так, чтобы эти сообщения уровня DEBUG не вошли так:

<!-- Elevate the log level for 'org.springframework.scheduling' since in 
    process of registering the scheduled task, Spring's 
    ScheduledAnnotationBeanPostProcessor tries to find TaskScheduler and 
    ScheduledExecutorService beans and then fallbacks to its internal 
    scheduler but in the process logs exceptions when it cannot find those 
    beans registered. 
--> 
<logger name="org.springframework.scheduling"> 
    <level value="info" /> 
</logger>
