Gradle构建Web项目简单教程

背景：
最近，公司的项目是使用Gradle进行构建Web项目，为此需要写一份简单的Gradle教程作为构建项目文档。

Gradle项目构建脚本 -> build.gradle

// 创建Java项目插件，提供了所有构建和测试Java程序所需项目结构
apply plugin: 'java'
// 引入Maven插件，以便Gradle可以引用Maven仓库的Jar包
apply plugin: 'maven'
// 进行打包插件
apply plugin: 'war'
// Web项目服务器插件,此处配置后，不需再单独配置Web服务器
apply plugin: 'jetty'
// Web项目开发插件
apply plugin: 'eclipse'

// 启动jetty容器的配置参数
jettyRun {
    // 自动热切换
    reload = "automatic" 
    scanIntervalSeconds = 0
    // http端口号
    httpPort = 8088
    // 停止jetty容器
    stopPort = 8082
    stopKey = "stopKey"
}

group = "com.suneee"
// 指定编译*.java文件的JDK版本
sourceCompatibility = 1.8
version = '1.0'
// Web项目示例工程
jar {
    manifest {
        attributes 'Implementation-Title': 'Gradle Quickstart', 'Implementation-Version': version
        // 题外话：Java项目，此处可以用来配置程序入口点
        // attributes 'Main-Class':'com.suneee.**'
    }
}
// 默认情况，Gradle没有定义任何资源库
repositories {
    // 使用Maven的中央存储库
    mavenCentral()
    // 使用Maven的本地存储库
    mavenLocal()
}
// 增加自定义的库
repositories {
    flatDir{
            // 项目目录下的lib文件夹
            dirs 'lib' 
        }
}
// 解决Gradle编译时出现： 编码GBK的不可映射字符
[compileJava, compileTestJava]*.options*.encoding = 'UTF-8'

// 解决项目Jar包依赖问题
dependencies {
    // 编译时，加入项目目录下lib文件
    compile fileTree(dir:'lib',include:'*.jar')
    compile 'c3p0:c3p0:0.9.1.2'
    compile 'mysql:mysql-connector-java:5.1.31' 
    compile 'org.springframework.data:spring-data-redis:1.3.4.RELEASE'
    compile group: 'com.google.code.gson', name: 'gson', version: '2.7'
    compile group: 'commons-collections', name: 'commons-collections', version: '3.2'
    testCompile "org.springframework:spring-test:4.1.0.RELEASE"
    testCompile group: 'junit', name: 'junit', version: '4.+'
    compile 'com.alibaba:dubbo:2.8.4a'
    compile 'org.apache.zookeeper:zookeeper:3.4.8'
    compile 'com.101tec:zkclient:0.8'
    compile 'log4j:log4j:1.2.17'
    compile group: 'javax.activation', name: 'activation', version: '1.1.1'
    compile group: 'javax.mail', name: 'mail', version: '1.4.7'
    compile group: 'org.quartz-scheduler', name: 'quartz', version: '1.7.2'
    compile group: 'aspectj', name: 'aspectjweaver', version: '1.5.4'
    compile group: 'org.hibernate', name: 'hibernate-core', version: '5.1.0.Final'
    compile group: 'org.hibernate', name: 'hibernate-entitymanager', version: '5.1.0.Final'
    compile group: 'org.springframework', name: 'spring-orm', version: '4.2.4.RELEASE'
    
}

test {
    systemProperties 'property': 'value'
}

// 发布项目导出的Jar包到指定仓库
uploadArchives {
    repositories {
       flatDir {
           dirs 'repos'
       }
    }
}

项目组使用的是eclipse进行开发，并且前后端进行完全分离架构。

作为项目后端的开发组成员，只需要开发Service层，Dao层即可，大大的减轻了后端开发组成员的任务，同时项目后端开发组成员比较对提供的API有过完整的单元的测试。

Talk is cheap,show me the code.
接口定义

// service layer 
public interface HotelOrderService {
    public Page queryCheckin(CheckinHOCDto checkin);
