一、前言

上個月由於做了一個小的後臺系統，重新拾起Spring，發現之前搞的SSH、SpringMVC已經過時，新的SpringBoot整合了大部分的後端框架，俗稱Spring全家桶，還集成了tomcat更方便開發測試，故在寫專案的同時順便學習一下SpringBoot。由於本人目前主攻Android方向，所以對Intellj家族和Gradle更為喜歡，所有使用 IDEA、Gradle 、Gradle多Module 來開發SpringBoot，也使得Android開發習慣無縫遷移到SpringBoot開發上。相信IDEA、Gradle會是Web開發的主流環境。

二、建立專案

1、使用IEAD建立Gradle專案

###2、輸入工程名，GroupId不用寫

###3、使用gradle wrapper

###4、建立名為app的主module

###5、建立名為common的module

###6、將根目錄settings.gradle 改為

include 'app'
include 'common'

###7、將根目錄的build.gradle 改為

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
 

        jcenter()
    }
    dependencies {
        //AndroidStudio中開發springboot 使用apply plugin: 'org.springframework.boot'會有問題，必須新增一個AndroidModule才能正常。
        //使用Intellj 開發純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、將app內的build.gradle改為

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'

version = '1.0.0'

tasks.withType(JavaCompile) {

###9、同步gradle下載依賴庫

###10、環境好了，新增測試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、啟動

###1、命令列啟動

gradlew bootRun

###2、執行TestController的Main方法

四、效果

###1、在瀏覽器內開啟http://localhost:8080

###2、整體專案結構
