It is recommended to add a timeout option to the client code in the quick start of the sofa-rpc official website document.

建议 sofa-rpc 官网文档 快速开始 中Client代码增加超时选项

• 官网文档 快速开始
• 这个文档中client的代码没有.setConnectTimeout() 导致有可能跑demo的时候超时导致提示服务不可用

Exception in thread "main" com.alipay.sofa.rpc.core.exception.SofaRouteException: RPC-020020009: 当前服务[sofaRPC.HelloService:1.0]的地址[bolt://127.0.0.1:12200,]不可用,或指定的地址不在可用的地址列表中

• 而github中对应demo的client代码中含有.setConnectTimeout()
• 建议将官网代码添加setConnectTimeout
