[GitHub] [incubator-dubbo] BellaJiangxia opened issue #2720: 路由规则无法生效的问题
在管理页面设置了该路由规则，没起作用，
我看网上说“使用URL描述一条路由规则，并将存储在注册中心${service}/routers目录下，然后通知相关订阅者（服务消费者【调用方】）。“，这句话什么意思，是还要在zookeeper里面配置什么吗

是不是把优先级理解反了？越小优先级越高。

我理解了，就是过滤条件就是调用满足该过滤条件的服务吧，但是现在有个问题，两个路由规则，一个过滤条件为调用20880端口服务，优先级0，一个调用20883端口服务，优先级4，为啥反而执行优先级为0的路由规则呢

```java
@Override
public int compareTo(Router o) {
if (o == null || o.getClass() != ConditionRouter.class) {
return 1;
}
ConditionRouter c = (ConditionRouter) o;
return this.priority == c.priority ? url.toFullString().compareTo(c.url.toFullString()) : (this.priority > c.priority ? 1 : -1);
}
```
优先级越小优先执行

消费者打印出来的数据依然是20883端口的

意思是说，你在控制台上配置了路由规则之后，对应的路由规则会存储在 zookeeper 的 `/dubbo/${service}/routers` 下。

然后就可以直接消费者了吧？还是需要做什么事？我设置了两个
，就是说不能访问20883端口和20881端口，还剩一个20880的提供者，但是调用的服务并不是20880上的

我测试了一下，感觉是优先级越低的越靠前执行呢

事实上是优先级越低的越先执行吗

return this.priority == c.priority ? url.toFullString().compareTo(c.url.toFullString()) : (this.priority > c.priority ? 1 : -1);
}
```
优先级越小优先执行，比如router1 优先级0, router2 优先级1， router1和router2配置一样，先执行router1的结果，然后把结果交给router2继续执行
