1使用idea创建springboot项目如下图所示 并选择web模块
2，登录springboot官网 http://projects.spring.io/spring-boot/ 引入相关依赖包如图所示我们这里是基于1.5.8
3.引入springboot核心包，开始我们的helloworld之旅，pom文件如图所示
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</dependencies> <!--maven插件-->
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build> </project>
4、编写启动类（注意启动类一般放在包的最外包）因为启动类只会扫描本报子包，同级包中的信息不然会报错
package cm.test.cn; import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication
public class SpringbootTestApplication { public static void main(String[] args) { SpringApplication.run(SpringbootTestApplication.class, args);
}
}
5、编写controller
package cm.test.cn.controller; 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;
import org.springframework.web.bind.annotation.RestController; @RestController
@EnableAutoConfiguration
public class SampleController {
@RequestMapping("/hello")
public String home() { return "Hello World!";
} }
此时我们启动，这个启动类并在浏览器窗口访问如下图所示一个简单的hello,world就完成了，很简单吧！
