## 问题描述
使用如下方式配置RegistryConfig bean时

```java
    @Bean
    public RegistryConfig registryConfig() {
        RegistryConfig registryConfig = new RegistryConfig();
        registryConfig.setProtocol("zookeeper");
        registryConfig.setAddress("localhost");
        registryConfig.setPort(2181);
        return registryConfig;
    }
```

提示无法与zookeeper建立连接，调试代码发现，zookeeper链接为

`zookeeper://localhost:9090/ConfigCenterConfig?check=true&config-file=dubbo.properties&group=dubbo&highest-priority=false&namespace=dubbo&timeout=3000`

使用了9090端口，未使用2181端口，registryConfig.setPort()不生效。

对比测试，使用registryConfig.setAddress("localhost:2181")方式可以生效。
