我们使用方法分组来用dubbo，每个分组有自己权限，但是dubbo:registry标签 username & password 不生效，
让我不得不使用
```
    <dubbo:registry
            address="zookeeper://username:pwd@ip:port"
            group="xxx"/>
```
这种写法失效
```
    <dubbo:registry
            address="zookeeper://ip:port"
            username="username"
            password="pwd"/>
```

            throw new IllegalStateException("The local implementation class " + localClass.getName() +
                    " not implement interface " + interfaceClass.getName());
        }
        try {
            //
            ReflectUtils.findConstructor(localClass, interfaceClass);
        } catch (NoSuchMethodException e) {
            throw new IllegalStateException("No such constructor \"public " + localClass.getSimpleName() +
                    "(" + interfaceClass.getName() + ")\" in local implementation class " + localClass.getName());
        }
    }

            configedRegistries.addAll(getSubProperties(Environment.getInstance().getExternalConfigurationMap(),

                            registryConfig.refresh();
