前提条件

Eclipseが下の状態にあること

EclipseでGradle Java Porjectを新規作成する

Spring IOをbuild.gradleに設定する

下を参考に前提条件のbuild.gradleに// Addを追記

Spring IO Platform Reference Guide
4.2 Using Spring IO Platform with Gradle
http://docs.spring.io/platform/docs/1.1.2.RELEASE/reference/htmlsingle/#getting-started-using-spring-io-platform-gradle

build.gradle

// Add
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'io.spring.gradle:dependency-management-plugin:0.4.1.RELEASE'
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
// Add
apply plugin: 'io.spring.dependency-management'

sourceCompatibility = 1.5
version = '1.0'
jar {
    manifest {
        attributes 'Implementation-Title': 'Gradle Quickstart',
                   'Implementation-Version': version
    }
}

repositories {
    mavenCentral()
}

// Add
dependencyManagement {
    imports {
        mavenBom 'io.spring.platform:platform-bom:1.1.2.RELEASE'
    }
}

dependencies {
    // Add
    compile 'org.springframework.boot:spring-boot-starter-web'

    compile group: 'commons-collections', name: 'commons-collections', version: '3.2'
    testCompile group: 'junit', name: 'junit', version: '4.+'
}

test {
    systemProperties 'property': 'value'
}

uploadArchives {
    repositories {
       flatDir {
           dirs 'repos'
       }
    }
}

依存関係を更新

追記分を反映させるため依存関係を更新する
Package ExplorerでProjectのRoot要素を選択、右クリック
Gradle → Refresh All
Gradle Dependencies下に依存するLibraryが追加される

アプリケーション作成

下を参考にhello/SampleController.javaを作成

Spring Boot
Quick Start
http://projects.spring.io/spring-boot/#quick-start

hello/SampleController.java

package hello;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@EnableAutoConfiguration
public class SampleController {

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

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

アプリケーションを実行

Package Explorerでhello/SampleController.javaを選択、右クリック
Debug As → Spring Boot App

ブラウザで下のURLを開く
http://localhost:8080/
