暂时完成效果图如下：

1.登录界面

输入任意用户名与密码（暂时没有设置登录验证等，后期添加），点击用户登录进入主页面

在左下角，显示了你刚才输入的用户名，实现了数据的传输。

代码模块展示如下：

app.js

/*
 * This file is generated and updated by Sencha Cmd. You can edit this file as
 * needed for your application, but these edits will have to be merged by
 * Sencha Cmd when upgrading.
 */
Ext.application({
    name: 'oaSystem',

    extend: 'oaSystem.Application',
    
    //autoCreateViewport: 'oaSystem.view.main.Main',
	
    //-------------------------------------------------------------------------
    // Most customizations should be made to oaSystem.Application. If you need to
    // customize this file, doing so below this section reduces the likelihood
    // of merge conflicts when upgrading to new versions of Sencha Cmd.
    //-------------------------------------------------------------------------

});

1.第一步：使用sencha cmd 创建项目 名称需要注意 输入为oaSystem
   我使用的命令如下：sencha -sdk  E:\openSrc\ext-5.0.0 generate app oaSystem E:\workspaces\myeclipse2014\csdn
如果不太清楚sencha cmd的命令参数，建议先阅读 http://blog.csdn.net/sushengmiyan/article/details/38313537

2.第二步：使用sencha app build 命令构建应用程序，使用sencha web start 测试是否成功。
建议先阅读：http://blog.csdn.net/sushengmiyan/article/details/38331347

3.将刚才新建目录下的app文件夹全部删除，将下载的压缩文件解压缩，直接解压缩到项目目录即可，重新build运行。
