誰かがこのエラーを克服するために私を助けることができます。 これに関連するコードの変更は次のとおりです。

HelloController.java

package com.mycompany.controller; 

import org.springframework.stereotype.Controller; 
import org.springframework.ui.Model; 
import org.springframework.web.bind.annotation.RequestMapping; 

@Controller 
public class HelloController { 

    @RequestMapping(value = "/greeting") 
    public String sayHello(Model model) { 

     model.addAttribute("greeting", "Hello World!!"); 

     return "hello"; 
    } 

}
