SpringBoot 中 @ConfigurationProperties 配置后 apollo 自动刷新

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

spring.boot.enableautoconfiguration=true

2.实现ApplicationContextAware

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;@AutowiredRefreshScope 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();}@Overridepublic void setApplicationContext(ApplicationContext applicationContext) throws BeansException {this.applicationContext = applicationContext;}
}
