1.创建一个helloworld主程序类
/**
* @SpringBootApplication 用来标注一个主程序类,这是一个SpringBoot应用
*/
@SpringBootApplication
public class SpringBootHellowordConfigApplication {
public static void main(String[] args) {
//Spring应用启动
SpringApplication.run(SpringBootHellowordConfigApplication.class,args);
}
}
2.写一个controller
@Controller
public class HelloController {
@ResponseBody
@RequestMapping("/hello")
public String helloController(){
return "hello controller";
}
}
3.运行主配置类,后查看端口号
4.浏览器运行:http://localhost:8081/hello 即可
