初學spring boot，按照網上教程，用eclipse +maven+spring boot 創建了一個項目，controller非常簡單，代碼如下:

package com.example.demo.Controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class demoController
{
@ResponseBody
@RequestMapping("demo")
public String demo()
{
return "hello world;hello spring boot";
}
}

運行後，console出現以下訊息：

但我在eclipse自帶瀏覽器輸入：http://localhost:8080/，卻出現以下訊息：

The webpage cannot be found

請問問題出在哪裏？

我用的tomcat是maven內崁的，請問如何配置？

源码包Openssh7.9如何自启动？
