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(
            "org.slf4j:slf4j-api:1.7.21",
            "org.apache.logging.log4j:log4j-slf4j-impl:2.7",

    testCompile(

    )
}

//    自动创建好src目录  包括源码与测试源码
task mkdirs << {
    sourceSets*.java.srcDirs*.each { it.mkdirs() }

}

// 显示当前项目下所有用于 compile 的 jar.
task listJars(description: 'Display all compile jars.') << {
    configurations.compile.each { File file -> println file.name }
}
