本バージョン:Spring Boot 1.5.7.RELEASE
1.使用要求
オススメjava 8(1.6/1.7 Springboot 1.x.xも使えます)、Maven(3.2+)

Spring Boot 2.0.0.BUILD-SNAPSHOT requires Java 8 and Spring Framework 5.0.0.RELEASE or above;
Explicit build support is provided for Maven (3.2+), and Gradle 4.

#    
$ java -version
$ mvn -v

SpringBootは多くのStarter POMを提供し、Jarsを簡略化するためにclassipathに追加する動作

を提供する.

spring-boot-starter-parentはparentノードとして、Mavenのデフォルト設定とバージョン制御を提供していますので、望む(「blesed」)の依存はversionフラグ

を省略することができます.

spring-boot-starter-parent自体は任意の依存性を導入しない(mvn dependency:tree)

他のStarter POMも特定のタイプのアプリケーションを開発するために必要な依存性だけを提供し、必要に応じて

を導入する.

spring-boot-starter-web依存ツリーには、springboot、spring-webmvc、tomcat、jackson、hibernal-validatorなどの

が含まれています.
3.コード

package com.top.test.springboot;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

@RestController//@ResponseBody + @Controller
public class HelloController {
    @RequestMapping(value="/hello")
    public String helloWorld() {
        return "hello world!";
    }
}

package com.top.test.controller;

import java.util.Arrays;

import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

/**
 * @SpringBootApplication  : @Configuration + @ComponentScan + @EnableAutoConfiguration
 *   @Configuration      ;@ComponentScan       /  ;@EnableAutoConfiguration      
 */
//@SpringBootApplication
@EnableAutoConfiguration
@ComponentScan(basePackages="com.top.test")//          
public class HelloApplication {
    
    public static void main(String[] args) {
        SpringApplication.run(HelloApplication.class, args);
    }
    
    //  app      springboot     bean,     
    @Bean
    public CommandLineRunner commandLineRunner(ApplicationContext ctx) {
        final String[] beanNames = ctx.getBeanDefinitionNames();
        return new CommandLineRunner() {
            @Override
            public void run(String... args) throws Exception {
                System.out.println("Let's inspect the beans provided by Spring Boot:");
                Arrays.sort(beanNames);
                for (String beanName : beanNames) {
                    System.out.println(beanName);
                }
            }
        };
    }
}

Auto-configrationはStarter POMとよく協力して使うことができますが、両者は直接連絡していません.Starter POM以外のjarは依存しています.Spring Bootは依然として自動配置

に最善を尽くします.

main方法は、アプリケーションの入口であり、SpringBootのSpringApplication類の呼び出しを依頼するrun()であり、アプリケーションを起動する(自動的に配置されたTomcatを起動することを含む)

.
4.運転

- 1. project   ，     mvn spring-boot:run
- 2.  IDE：  main  Run as Java Application ||   maven build(   1) 
- 3.   jar, java -jar xxx.jar

ブラウザのアクセス:http://localhost:8080/hello
このうち、jarとして包装して実行します.spring-boot-maven-pluginプラグインを利用します.
starter parentにはパッケージの配置があります.spring-boot-starter-parentを使わないとPOM.xmlにパッケージを自分で配置しなければなりません.ここでstarter parentを使っています.spring-boot-maven-pluginプラグインを導入すればいいです.
