有人可以帮助我克服这个错误吗？以下是我与此相关的代码更改。

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";
    }

}

如果您使用 Java 1.8，则需要 Spring 3.2.16 或更高版本。使用正确的 spring 版本更新您的 pom.xml 将解决该问题
