spring 4.0.3整合Hessian4.0.38 IDEA

1.1 Hessian簡介

Hessian是一個輕量級的remoting onhttp工具，使用簡單的方法提供了RMI的功能。相比WebService，Hessian更簡單、快捷。采用的是二進制RPC協定，因為采用的是二進制協定，是以它很适合于發送二進制資料。

1.2 整合

對于Hessian是分服務端和用戶端的，網上的一些例子也是大部分分開的（SpringMVC整合Hessian通路遠端服務）。這裡使用IntelliJ IDEA把服務端和用戶端整合在一個項目裡面。利用maven統一管理包。其他module直接繼承依賴。
