当我尝试使用 STS 运行 Spring MVC 时，我得到请求的资源 () 不可用

Question

我是 Spring MVC 和 Spring/Hibernate 的新手。

我正在尝试运行我在网上找到的示例尝试执行此操作但无法成功运行它。

我的 web.xml 如下

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</servlet>

<servlet-mapping>

</servlet-mapping>

<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>

我的ArticleController.java 如下

package net.roseindia.controller;

import java.util.HashMap;
import java.util.Map;

import net.roseindia.model.Article;
import net.roseindia.service.ArticleService;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

@Controller
@RequestMapping("/articles")
public class ArticleController {

  @Autowired
  private ArticleService articleService;

  @RequestMapping(value = "/save", method = RequestMethod.POST)
  public ModelAndView saveArticle(@ModelAttribute(" article") Article  article,
        BindingResult result) {
     articleService.addArticle( article);
     return new ModelAndView("redirect:/articles.html");
  }

  @RequestMapping(method = RequestMethod.GET)
  public ModelAndView listArticles() {
        Map<String, Object> model = new HashMap<String, Object>();
        model.put("articles",  articleService.listArticles());

     return new ModelAndView("articlesList", model);
  }

  @RequestMapping(value = "/add", method = RequestMethod.GET)
  public ModelAndView addArticle(@ModelAttribute("article") Article article,
         BindingResult result) {
    return new ModelAndView("addArticle");
  }

}

有人可以帮我解决这个错误吗？

预先感谢您。

Answer 1

我建议以下步骤应该解决这个特定问题

右键单击​​该项目 -->属性-->部署组装 -->添加

您可以添加所有文件夹
（例如源：/src/main/java --> 部署路径：WEB-INF/classes）
到特定的部署路径

我认为这会有所帮助。
