cmd命令打jar是如下实现：
在运行里输入cmd，利用cmd命令进入到本地的工作盘符。(如我的是D盘下的文件有此路径 D:\workspace\prpall\WEB-INF\classes)
现在是想把D:\workspace\prpall\WEB-INF\classes路径下所有的文件打包成prpall.jar。然后继续如下操作：
cd D: 回车
cd workspace/prpal

随着RESTful Web Service的流行，测试对外的Service是否满足期望也变的必要的。从Spring 3.2开始Spring了Spring Web测试框架，如果版本低于3.2，请使用spring-test-mvc项目（合并到spring3.2中了）。
Spring MVC测试框架提供了对服务器端和客户端（基于RestTemplate的客户端）提供了支持。
