啟動報錯，比較特殊，dubbo啟動時IP地址找錯了？

實現DubboItemService后，第一次啟動，報錯說不存在

javassist.ClassPool

搜索后說缺少依賴：

<dependency>
????<groupId>org.javassist</groupId>
????<artifactId>javassist</artifactId>
????<version>3.20.0-GA</version>
</dependency>

遂加進去，啟動又報錯：

Error?creating?bean?with?name?'dubboItemInfoService'?defined?in?file?(這里省略類路勁）
:?Initialization?of?bean?failed;?nested?exception?is?com.alibaba.dubbo.rpc.RpcException:?

我一查IP，發現我的IP不是192.168.206.1。我在本機裝了VMWare虛擬機，但我并沒有啟動他們，像下圖一樣：
