我正在tomcat上部署我的项目,然后我收到此错误"在DispatcherServlet中找不到带有URI [/ HelloWeb /]的HTTP请求的映射,名称为'HelloWeb'".
这是我的web xml文件 web.xml
<web-app xmlns="http://java.sun.com/xml/ns/javaee"

我的控制器HelloController.java
package com.tutorialspoint.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
public class HelloController {
@RequestMapping(value = "/hello", method = RequestMethod.GET)
public String printHello(ModelMap model) {
model.addAttribute("message", "Hello Spring MVC Framework!");
return "hello";
}
}
为hello.jsp
<%@ page contentType="text/html; charset=UTF-8" %>
<html>
<head>
<title>Hello World</title>
</head>
<body>
<h2>${message}</h2>
</body>
</html>
谁能告诉我代码中有什么问题？
您没有/HelloWorld/仅用于的映射/hello/
转到您的基本应用程序位置localhost:8080/myApp/，然后转到/hello，您的 jsp 应该会返回。那么你的 war 文件名在localhost:8080/myApp/hello哪里myApp（假设它不是 root）。
