2 搭建Hello world

<1 首先新建一个maven 工程 bootside01 ，编辑pom.xml添加

<properties>

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

<java.version>1.8</java.version>

</properties>

<parent>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-parent</artifactId>

<version>1.5.2.RELEASE</version>

</parent>

<dependencies>

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter</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-web</artifactId>

</dependency>

</dependencies>

<build>

<plugins>

<plugin>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-maven-plugin</artifactId>

</plugin>

</plugins>

<2 新建 HelloController 类

@RestController

public class HelloController {

@RequestMapping("/hello")

public String index(){

return "Hello World";

}

@RequestMapping("/hehe")

public String hehe(){

return "HE HE";

}

}

<3新建 SpringStarter 类启动

/**

* 启动入口

* @author ysd

*/

@EnableAutoConfiguration

@SpringBootApplication

public class SpringStarter {

public static void main(String[] args) throws Exception {

SpringApplication.run(SpringStarter.class, args);

}

}

显示的结果如下图
