概念东西就不多说，可以去官网。
环境：spring-4.2.6+springBoot-1.3.5+maven+jdk-1.8

1. 这里是列表文本首先新建一个maven项目



2.编辑 POM文件

<dependencies>

<!-- spring -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>4.2.6.RELEASE</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.2.6.RELEASE</version>
</dependency>

<!-- spring boot -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>1.3.5.RELEASE</version>
</dependency>
</dependencies>

<build>
<finalName>${project.artifactId}</finalName>
<plugins>
<!-- 资源文件拷贝插件 -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.7</version>
<configuration>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
<!-- java编译插件 -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.2</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
</plugins>
</build>

3.新建一个带main方法的class文件

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 SpringBootTest {

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

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

4.运行main方法，默认端口是8080。然后在浏览器输入：http://localhost:8080
