，如何删除链接（HREF）

Question

package net.roseindia.controller; 

import net.roseindia.service.ArticleService; 

import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestParam; 


@Controller 
@RequestMapping("/articles") 
public class DeleteController { 
    @Autowired 
     private ArticleService articleService; 

     @RequestMapping(value="/delete") 
     public String deleteService(@RequestParam("ID") final Integer ids) { 
      System.out.println("hello"); 
      articleService.deleteService(ids); 

      return "redirect:/articles"; 

     } 

} 

可以在这里~~~~~~~~~~~~~~~~~~~~~~

<td><a href="/articles/delete.do?ID=${article.articleId}">delete</a></td> 

这个问题只是贴了我lot.I认为这可能是href.Controller的问题不能把握的HREF

的链接（第二次尝试），但似乎还没有这样的

import net.roseindia.service.ArticleService; 

import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.PathVariable; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestParam; 


@Controller 
@RequestMapping("/articles") 
public class DeleteController { 
    @Autowired 
     private ArticleService articleService; 

     @RequestMapping(value="/delete/{ID}") 
     public String deleteService(@PathVariable("ID") final Integer ids) { 
      System.out.println("hello"); 
      articleService.deleteService(ids); 

      return "redirect:/articles"; 

     } 

} 

    td><a href="/articles/delete/${article.articleId}.html">delete</a></td> 

这方面的工作是我的web.x毫升

<?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"

Promble是

HTTP状态404 - /articles/delete/2.html

类型状态报告

消息/articles/delete/2.html

description请求的资源不可用。

Answer 1

HTTP 404错误的原因是没有为您的http请求找到映射。从您的配置看来，您的控制器和请求映射没有得到配置。

你需要一些上下文配置定义调度如下：

<servlet> 
    <servlet-name>dispatcher</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
    <init-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value>/WEB-INF/spring/servlet-context.xml</param-value> 
    </init-param> 
    <load-on-startup>1</load-on-startup> 
</servlet> 

，然后在servlet-context.xml，您需要定义组件扫描如下扫描您的注解驱动控制器：

<annotation-driven /> 
<context:component-scan base-package="net.roseindia.controller" />
