新手--请教tomcat(spring-boot)问题

吃不胖的茶叶蛋 2016-08-20 11:02:37

用maven构建spring-boot项目，运行时main提示tomcat已启动，但是我在浏览器里访问localhost：8080/ 却是404错误，why？

基础代码：

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;



@RestController

@EnableAutoConfiguration

public class Application {

	@RequestMapping("/")

    public String home() {

		return "<html><head><title>Hello World!</title></head><body><h1>Hello World!</h1><p>This is my first web site</p></body></html>";

    }



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

        SpringApplication.run(Application.class, args);

    }

}

console结果：
