Spring Boot官网：http://projects.spring.io/spring-boot/
环境准备：maven 3.3.5、jdk8、Idea
1.创建maven项目工程
2.引入starters
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.11.RELEASE</version>
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>
3.创建主程序
@SpringBootApplication
public class HelloWorldMainApplication { public static void main(String[] args){
//Spring 应用启动起来
SpringApplication.run(HelloWorldMainApplication.class, args);
}
}
4.创建一个Controller
@Controller
public class HelloController { @RequestMapping("/hello")
@ResponseBody
public String hello(){
return "Hello Word!";
}
}
5.运行主方法，并在浏览器输入：localhost:8080/hello ，就会出现Hello Word!
6.也可以打包成jar包 进行部署
url:https://docs.spring.io/spring-boot/docs/1.5.11.RELEASE/reference/htmlsingle/#getting-started-first-application-executable-jar
这个插件，可以将应用打包成一个jar包
