Bootstrap框架----多项关联—check选择

我们之前已经记录了两种多项关联的交互方式，标签和列表
Bootstrap框架—-多项关联—标签式选择
Bootstrap框架—-多项关联—列表选择

本章记录第三种多项关联的交互–check选择，适用于中等数量的多项关联。

效果如图:

我们在之前的文章中已经在SpringMVC基础框架的基础上应用了BootStrap的后台框架，在此基础上记录 check选择。
应用bootstrap模板

基础项目源码下载地址为:
SpringMVC+Shiro+MongoDB+BootStrap基础框架

我们在基础项目中已经做好了首页index的访问。
现在就在index.jsp页面和index的路由Controller上做修改，实现 check选择，传给后台保存成List用法。
