web工程之SSM快速搭建示例程序(文末含代碼附件)

技術簡介

Spring+SpringMVC+Mybatis
前端框架：velocity，ace admin, jquery。

SpringMVC

Spring MVC屬於SpringFrameWork的後續產品，已經融合在Spring Web Flow裏面。Spring Web MVC是一種基於Java的實現了Web MVC設計模式的請求驅動類型的輕量級Web框架，將web層進行職責解耦，基於請求驅動指的就是使用請求-響應模型，框架的目的就是幫助我們簡化開發。
SpringMVC請求處理流程流程圖：

Velocity

Velocity 是一個基於java 的模板引擎（template engine）。它性能良好，不支持java代碼所以能實現嚴格的MVC分層。支持VTL表達式語言、宏定義。velocity宏非常好用，類似函數，一處聲明，其它地方一行代碼即可引用，見文末分頁宏示例。
代碼示例：聲明用#，變量引用$，foreach和宏使用。

標準頁面寫法

<div id="dialog"></div>
#set($footerJs=["jquery.nestable.min.js","jquery-ui.custom.min.js",])

不使用layout的寫法

#set($layout = "/common/blank.vm")
