Question

我有一项任务是将一些数据写入db并且工作正常。但是当a使它成为一个计划任务时它会启动但在访问数据库时抛出org.hibernate.HibernateException: No Session found for current thread。

这是我的bean.xml

Spring配置：

@EnableScheduling
@Configuration
public class SpringConfiguration {

    @Inject
    private ApplicationContext context;

    @PostConstruct
    public void registerListeners() {
        SessionFactory sessionFactory = context.getBean(SessionFactory.class);
        EventListenerRegistry registry = ((SessionFactoryImplementor) sessionFactory).getServiceRegistry().getService(
                EventListenerRegistry.class);
        registry.getEventListenerGroup(EventType.POST_LOAD).appendListener(new PostLoadEventListener());
    }

    @Bean
    public Validator getValidator() {
        ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
        return factory.getValidator();
    }
}

任务：

@Service
public class Job {

  @Inject
  private ConfigurationHolder configurationHolder;

  @Scheduled(cron = "0 0 11 * * *")
  public void run() {
    JobConfiguration configuration = configurationHolder.getConfiguration(JobConfiguration.class);
    ...
    User user = User.getById(userId);
    ...
  }
}

注入配置工作正常。可能是什么问题？
