新建一个maven 项目

pom 文件：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">    <modelVersion>4.0.0</modelVersion>    <groupId>com.sgcai</groupId>    <artifactId>springboot_test</artifactId>    <packaging>war</packaging>    <version>1.0-SNAPSHOT</version>    <name>springboot_test Maven Webapp</name>    <url>http://maven.apache.org</url>    <dependencies>        <dependency>            <groupId>junit</groupId>            <artifactId>junit</artifactId>            <version>3.8.1</version>            <scope>test</scope>        </dependency>        <!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-dependencies -->        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-dependencies</artifactId>            <version>1.5.1.RELEASE</version>        </dependency>        <!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-web -->        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>            <version>1.5.1.RELEASE</version>        </dependency>    </dependencies>    <build>        <plugins>            <plugin>                <groupId>org.springframework.boot</groupId>                <artifactId>spring-boot-maven-plugin</artifactId>            </plugin>        </plugins>        <finalName>springboot_test</finalName>    </build></project>

main->java  路径下新建Java类：

package com.sgcai.boot;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;/** * Created by Administrator on 2017/2/14. */@SpringBootApplication@RestControllerpublic class Applicaiton {    public static void main(String[] args) {        SpringApplication.run(Applicaiton.class,args);    }    @RequestMapping("/")    public  String greeting(){        return "hello";    }}

注意：java类一定要有包名   否则报异常

运行main 方法即可
