搭建一个Web应用

2022-07-09 09:06:57

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(

             "junit:junit:4.12"

     )

 }

 //    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() }

     sourceSets*.resources.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 }
