[GitHub] [incubator-dubbo] cvictory commented on issue #3231: In dubbo-2.7 tag route, dubbo 2.6 client invoke 2.7 server work well but dubbo 2.7 client invoke 2.6 donot work well

["cvictory (GitHub)" <gi...@apache.org>]

In dubbo 2.6 , there are some key points in this class com.alibaba.dubbo.rpc.cluster.directory.AbstractDirectory.
 ```
    protected void setRouters(List<Router> routers) {
        // copy list
        routers = routers == null ? new ArrayList<Router>() : new ArrayList<Router>(routers);
        // append url router
        String routerkey = url.getParameter(Constants.ROUTER_KEY);
        if (routerkey != null && routerkey.length() > 0) {
            RouterFactory routerFactory = ExtensionLoader.getExtensionLoader(RouterFactory.class).getExtension(routerkey);
            routers.add(routerFactory.getRouter(url));
        }
        // append mock invoker selector
        routers.add(new MockInvokersSelector());
        Collections.sort(routers);
        this.routers = routers;
    }
```

so should we keep this logic code ?
