Spring定时任务service无法注入问题

package induconjob.config;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

@Component
public class ApplicationContextUtil implements ApplicationContextAware {

private static ApplicationContext applicationContext;

public static ApplicationContext getApplicationContext() {
return applicationContext;
}

@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
ApplicationContextUtil.applicationContext = applicationContext;

}

public static Object getBean(String beanName) {
return applicationContext.getBean(beanName);
}
}

获取service

DataFiledStatisticalService dataFiledStatisticalService = (DataFiledStatisticalService) ApplicationContextUtil.getBean("dataFiledStatisticalService");
