搭建一个Web应用

因为EasyUI会涉及到与后台数据的交互，所以使用Spring MVC作为后台，搭建一个完整的Web环境

使用gradle作为构建工具

build.gradle

 group 'org.zln.lkd'
 version '1.0-SNAPSHOT'

 apply plugin: 'jetty'

 sourceCompatibility = 1.8

 repositories {
     mavenLocal()
     mavenCentral()
 }

 dependencies {
     compile(

     testCompile(

     )
 }

 //    自动创建好src目录  包括源码与测试源码
 task mkdirs << {
