问题遇到的现象和发生背景
启动了Spring boot之后,浏览器访问http://localhost:8080/出错
操作环境、软件版本等信息
这是pom.xml的代码

这是主类SpringDemoApplication.java
package com.example.spring_demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
@SpringBootApplication
@ComponentScan(basePackages = "com.example")
public class SpringDemoApplication {
public static void main(String[] args) {
SpringApplication.run(SpringDemoApplication.class, args);
}
}
这是helloController.java
package com.example.spring_demo.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
/**
* @author mhw
* @create 2023/6/5 9:58
* @email 480738950@qq.com
*/
@Controller
public class helloController {
@RequestMapping("/index")
public String sayHello(){
return "index";
}
}
尝试过的解决方法
这是整个目录结构
我想要达到的结果
我想要在浏览器访问到index页面
