spring cloud动态刷新日志为什么还要加一个PostConstruct，只是监听logging.level.配置不就可以了吗
public class LoggerLevelRefresher implements ApplicationContextAware {
private ApplicationContext applicationContext;
@ApolloConfig
private Config config;
@PostConstruct
private void initialize() {
refreshLoggingLevels(config.getPropertyNames());
}
@ApolloConfigChangeListener(interestedKeyPrefixes = {"logging.level."})
private void onChange(ConfigChangeEvent changeEvent) {
refreshLoggingLevels(changeEvent.changedKeys());
}
private void refreshLoggingLevels(Set<String> changedKeys) {
System.out.println("Refreshing logging levels");
/**
* refresh logging levels
* @see org.springframework.cloud.logging.LoggingRebinder#onApplicationEvent
*/
this.applicationContext.publishEvent(new EnvironmentChangeEvent(changedKeys));
System.out.println("Logging levels refreshed");
}
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.applicationContext = applicationContext;
}
}Spring MVC工程中该如何配置加密解密
加密解密方法最好可以overwrite，只要固定加密方法即可
演示demo中的cloud写错了，应该为boot
我现在有个需求，就是在一个项目里面需要连接多个数据源，请问在apollo中如何配置？
后续研究一下~

场景：
删除了某项配置，还未发布，此时不想删除了；
修改某项配置，还未发布，此时不想修改了；
目前没有快捷的方式撤销之前的删除或修改，只能反向操作；
比如不想删除了，需要新增相同key-value的项；不想修改了，需要把value改回原来的值；步骤稍微繁琐了一些，如果有一键撤销的方式，就方便很多。
开发者你好。
我在使用openapi进行配置发布时，遇到了两个问题。
参考文档：3.2.13配置发布
我的平台：.NET 4.6
使用的SDK版本：Com.Ctrip.Framework.Apollo.OpenApi v2.10.0.0
以下是第一次调用与第二次管理端变化的截图
第一次
第二次
期待回复！
请问我们线上用的springboot1.5.4版本，这个版本找不到org.springframework.boot.context.properties.bind这个包，请问怎么解决
有这样一个case：
如果删除zuul原有的一个route配置，DiscoveryClientRouteLocator中使用的ZuulProperties不会更新，当然handlerMapping中的记录也不会删除。
虽然对业务可能影响很小，但是也算是一个遗留问题。
模仿示例,写了个druid的动态刷新数据源实现. DataSource更新成功,但查询的时候连接的还是旧数据源.是因为druid的问题吗
如果配置在一起的话，密文、密码在一起感觉加密的最用不大呀？
除了java应用在运行中实时listen namespace的配置, 实际上还有文件配置会出现差异情况,
在我们场景, 比如properties等包含数据源或其他需要在应用启动前读取的配置, 在应用启动前由shell通过不同参数从apollo拉取到本地, 从而实现一个镜像可以放在任何环境跑.
约定公共配置文件抽离到public, 有需要的关联覆盖相应配置项.
不知道这种算不算use case. 大致内容如下, 觉得可以的话我之后提交一个pr.

但是通过常规方式部署apollo-quick-start是能测试改case的。
请教一下，这种应该如何调试？
我调试的时候看到initialize 方法里面绑定的是application这个namespace，自己添加的listener只能监听application的变化？ 如果是能不能自定义
我测试了下 在 initialize 的时候自己来覆盖config 但是不行
`
@slf4j
@component
public class ApolloConfig implements ApplicationContextAware {
private ApplicationContext applicationContext;
@ApolloConfigChangeListener
public void onChange(ConfigChangeEvent changeEvent){
log.info("apollo conf update starts!");
// 更新configrationProperties
applicationContext.publishEvent(new EnvironmentChangeEvent(changeEvent.changedKeys()));
log.info("apollo conf update success!");
}
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.applicationContext = applicationContext.getParent();
}
}
`
这边能取到最新配置，但是使用@ConfigurationProperties(prefix = "spring.datasource")的配置还是久的值
Sentinel to Apollo to App
1.应用端获取配置中心的流控规则（限流规则、热点参数规则等）
2.Sentinel控制台持久化流控规则到配置中心
3.Sentinel控制台设置的流控规则，是否需要发布可通过参数配置
如果配置为false 则需要在配置中心进行发布操作
因为集群间有公共配置，所以想看下能否可行，现在客户端和服务端都是1.9.1的版本，目前现象看是不可行的
/**
* 监听apollo中配置global 文件的变化来维护map集合
* @param changeEvent
*/
@ApolloConfigChangeListener("global")
public void onChangeGlobal(ConfigChangeEvent changeEvent) {
for (String key : changeEvent.changedKeys()) {
ConfigChange change = changeEvent.getChange(key);
System.err.println("==========global:"+key);
map.put(key, change.getNewValue());
}
}
我现在想要实现路由信息的优先级为Apollo>配置文件
如果出现数据库连接错误，比如url写错了，会实例化一个HikariDataSource(null)，在重新配置新数据库设置后，将关闭上一个连接，进入terminateHikariDataSource()方法，执行poolMXBean.softEvictConnections()时抛会异常，致使不断循环直到达到最大重试次数，在terminate()方法中的if (dataSource instanceof HikariDataSource )添加一个非空检查可以避免不断重试。
引入jasypt-spring-boot-starter后，apollo本身的placeholder方式的自动刷新功能失效（包括未加密的key），refreshscope方式的不受影响可以正常刷新，请问有什么解决方法吗？谢谢！
