【问题描述】:
我是使用 Spring 的新手,因此决定学习本教程:
http://www.programcreek.com/2014/02/spring-mvc-helloworld-using-maven-in-eclipse/
我的文件和文件结构与教程相匹配,index.jsp 正在工作。但是,当我单击转到 helloworld.jsp 时,我收到以下 404 错误:
源服务器没有找到目标的当前表示 资源或不愿透露存在的资源。
任何人都可以建议挖掘的地方吗?不适合Tomcat 8.5的教程有什么问题吗?还是更有可能是我的设置有问题?
编辑: 我安装了以下内容:
- Tomcat 8.5.14
- 带有 Spring IDE 的 Eclipse Neon
- Maven 3.5.0
如果有帮助,在我尝试将它与 Web/Spring 一起使用之前,Maven 一直在工作(即 mvn install 下载正确的库)
我添加了一个image 我的文件和下面是我认为相关的文件的实际代码:
UserController.java
package com.ankurmgoyal.hellotest.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class HelloWorldController {
String message = "Welcome to Spring MVC!";
@RequestMapping("/hello")
public ModelAndView showMessage(
@RequestParam(value = "name", required = false, defaultValue = "World") String name) {
System.out.println("in controller");
ModelAndView mv = new ModelAndView("helloworld");
mv.addObject("message", message);
mv.addObject("name", name);
return mv;
}
}
