简单配置

使用@Value注解的配置会自动刷新配置

复杂对象

方案一：

@Component("systemConfig")
@ConfigurationProperties(prefix = "system")
@EnableApolloConfig("system.yml")
public class SystemConfig {
 
    private Resource filePath;
    private Resource tempFilePath;
 
}


public class ApolloRefreshConfig implements ApplicationContextAware {
    @Autowired
    private SystemConfig systemConfig;
    private ApplicationContext applicationContext;

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

    @ApolloConfigChangeListener(value = "system.yml",interestedKeyPrefixes="system")
    private void configChange(ConfigChangeEvent changeEvent){
        this.applicationContext.publishEvent(new EnvironmentChangeEvent(changeEvent.changedKeys()));
        log.info("appConfig,{}",JSON.toJSONString( systemConfig));
    }

方案二：

@Component("systemConfig")
@ConfigurationProperties(prefix = "cword")
@RefreshScope
@EnableApolloConfig("cword")
public class SystemConfig {
 
    private Resource filePath;
    private Resource tempFilePath;
 
    @Autowired
    private org.springframework.cloud.context.scope.refresh.RefreshScope refreshScope;
    @ApolloConfigChangeListener("cword")
    private void configChange(ConfigChangeEvent changeEvent){
        refreshScope.refresh("systemConfig");
    }
}
