apollo无法动态刷新ConfigurationProperties注解的类

这个问题，网上有很多解决方案，我采用的是如下这种最简单的解决方案，直接上代码：

package com.steven.schedule;

import org.apache.log4j.Logger;
import org.springframework.beans.BeansException;
import org.springframework.cloud.context.environment.EnvironmentChangeEvent;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

import com.ctrip.framework.apollo.model.ConfigChangeEvent;
import com.ctrip.framework.apollo.spring.annotation.ApolloConfigChangeListener;

/**

@Component
public class TaskSchedulePropertiesRefresher implements ApplicationContextAware {

	private static Logger logger = Logger.getLogger(TaskSchedulePropertiesRefresher.class);

	private ApplicationContext applicationContext;

	@ApolloConfigChangeListener
	public void onChange(ConfigChangeEvent changeEvent) {
		refreshTaskScheduleProperties(changeEvent);
	}

	private void refreshTaskScheduleProperties(ConfigChangeEvent changeEvent) {
		logger.info("Refreshing TaskSchedule properties!");

		// 更新相应的bean的属性值，主要是存在@ConfigurationProperties注解的bean
		this.applicationContext.publishEvent(new EnvironmentChangeEvent(changeEvent.changedKeys()));

		logger.info("TaskSchedule properties refreshed!");
	}

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

}
