一、创建一个Maven项目。

二、打开pom.xml文件，导入下面的配置(放在<\version>\标签之后)：

    <parent>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-parent</artifactId>        <version>1.4.0.RELEASE</version>    </parent>    <properties>        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>        <java.version>1.8</java.version>    </properties>    <dependencies>        <dependency>            <groupId>junit</groupId>            <artifactId>junit</artifactId>            <version>3.8.1</version>            <scope>test</scope>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-test</artifactId>            <scope>test</scope>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-thymeleaf</artifactId>        </dependency>    </dependencies>    <build>        <plugins>            <plugin>                <groupId>org.springframework.boot</groupId>                <artifactId>spring-boot-maven-plugin</artifactId>            </plugin>        </plugins>    </build>

三、创建Java类（在JAVA文件夹下先创建包）：

1、先创建Application类：

@SpringBootApplicationpublic class Application {    public static void main(String args[]){        SpringApplication.run(Application.class,args);    }}

2、创建Hello World类：

@RestController@EnableAutoConfigurationpublic class HelloWorld {    @RequestMapping("/hello")    public String hello(){        return "Hello World！";    }}

四、最后运行Application类，打开http://localhost:8080/就能看到hello world了
