1、在配置文件（如：application.properties）中，开启Apollo的自动更新

代码语言：javascript复制

spring.boot.enableautoconfiguration=true

2.实现ApplicationContextAware

代码语言：javascript复制

package com.qbz.test.commons.web.config;


import com.ctrip.framework.apollo.model.ConfigChangeEvent;
import com.ctrip.framework.apollo.spring.annotation.ApolloConfigChangeListener;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.context.environment.EnvironmentChangeEvent;
import org.springframework.cloud.context.scope.refresh.RefreshScope;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

/**
 * apollo 自动刷新
 *
 * @author qubianzhong
 * @Date 20:32 2019/11/11
 */
@Component
@Slf4j
public class ApolloRefreshConfig implements ApplicationContextAware {

    ApplicationContext applicationContext;

    @Autowired
    RefreshScope refreshScope;

	//这里指定Apollo的namespace，非常重要，如果不指定，默认只使用application
    @ApolloConfigChangeListener(value = {ConfigConsts.NAMESPACE_APPLICATION,"business","everything"})
    public void onChange(ConfigChangeEvent changeEvent) {
        for (String changedKey : changeEvent.changedKeys()) {
            log.info("apollo changed namespace:{} Key:{} value:{}", changeEvent.getNamespace(), changedKey, changeEvent.getChange(changedKey));
        }
        refreshProperties(changeEvent);
    }

    public void refreshProperties(ConfigChangeEvent changeEvent) {
        this.applicationContext.publishEvent(new EnvironmentChangeEvent(changeEvent.changedKeys()));
        refreshScope.refreshAll();
    }

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