[SpringBoot学习]-IDEA创建Gradle多Module结构的SpringBoot项目

一、前言

上个月由于做了一个小的后台系统，重新拾起Spring，发现之前搞的SSH、SpringMVC已经过时，新的SpringBoot整合了大部分的后端框架，俗称Spring全家桶，还记成了tomcat更方便开发测试，故在写项目的同时顺便学习一下SpringBoot。由于本人目前主攻Android方向，所以对Intellj家族和Gradle更为喜欢，所有使用 IDEA、Gradle 、Gradle多Module 来开发SpringBoot，也使得Android开发习惯无缝迁移到SpringBoot开发上。相信IDEA、Gradle会是Web开发的主流环境。

二、创建项目

1、使用IEAD创建Gradle项目

2、输入工程名，GroupId不用写

3、使用gradle wrapper

4、创建名为app的主module

5、创建名为common的module

6、将根目录settings.gradle 改为

include 'app'
include 'common'

7、将根目录的build.gradle 改为

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
//AndroidStudio中开发springboot 使用apply plugin: 'org.springframework.boot'会有问题，必须添加一个AndroidModule才能正常。
//使用Intellj 开发纯java工程或者 java web 更方便
//classpath 'com.android.tools.build:gradle:2.3.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}

allprojects {
repositories {
jcenter()
maven {
url "https://jitpack.io"
}
}
}

task clean(type: Delete) {
delete rootProject.buildDir
}

8、将app内的build.gradle改为

buildscript {
repositories {
jcenter()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.5.4.RELEASE")
}
}

repositories {
jcenter()
maven { url "http://maven.aliyun.com/nexus/content/groups/public/" }
maven { url "http://repo.maven.apache.org/maven2" }
}

apply plugin: 'org.springframework.boot'
apply plugin: 'java'
apply plugin: 'maven'

group = 'com.masonliu.cc'
version = '1.0.0'
description = """"""

sourceCompatibility = 1.8
targetCompatibility = 1.8

tasks.withType(JavaCompile) {
options.encoding = 'UTF-8'
}

sourceSets {
main {
//output.resourcesDir default is  'build/resources/main'
//output.classesDir default is  'build/classes/main'
//合并 classes 和 resources的输出路径，方便 直接执行 main方法时，在当前classpath下能找到 resources里的配置文件
output.resourcesDir = 'build/classes/main'
output.classesDir   = 'build/classes/main'
}
}

configurations {
deployerJars
}

//https://stackoverflow.com/questions/36923288/how-to-run-bootrun-with-spring-profile-via-gradle-task
//def profiles = 'dev'
//bootRun {
//    args = ["--spring.profiles.active=" + profiles]
//}

task pro << {
bootRun.systemProperty 'spring.profiles.active', 'pro'
}

task dev << {
bootRun.systemProperty 'spring.profiles.active', 'dev'
}

}

9、同步gradle下载依赖库

10、环境好了，添加测试controller

package com.masonliu.cc; /**
* Created by liumeng02 on 2017/10/30.
*/
import org.springframework.boot.*;
import org.springframework.boot.autoconfigure.*;
import org.springframework.stereotype.*;
import org.springframework.web.bind.annotation.*;

@Controller
@EnableAutoConfiguration

public class TestController {

@RequestMapping("/")
@ResponseBody
String home() {
return "Hello World!";
}

public static void main(String[] args) throws Exception {
SpringApplication.run(TestController.class, args);
}
}

三、启动

1、命令行启动

gradlew bootRun

2、执行TestController的Main方法

四、效果

1、在浏览器内打开http://localhost:8080

2、整体项目结构
