一、什么是sofa：  
SOFAStack（Scalable Open Financial Architecture Stack）是用于快速构建金融级分布式架构的一套中间件，也是在金融场景里锤炼出来的最佳实践。  
首先我们县城最简单的项目、SOFARPC 是蚂蚁金服开源的一款基于 Java 实现的 RPC 服务框架，为应用之间提供远程服务调用能力，具有高可伸缩性，高容错性，目前蚂蚁金服所有的业务的相互间的 RPC 调用都是采用 SOFARPC。SOFARPC 为用户提供了负载均衡，流量转发，链路追踪，链路数据透传，故障剔除等功能。SOFARPC 还支持不同的协议，目前包括 bolt，RESTful，dubbo，H2C 协议进行通信。其中 bolt 是蚂蚁金融服务集团开放的基于 Netty 开发的网络通信框架。

二、多的不说上代码：  
1、服务端：
