Answer 1

@RequestMapping(value="/delete")这样才对，刚才写错

Answer 2

谢谢你的回复，但是还是有问题
你的链接多了个&符号啊，你再检测下你的href。应该多了个&

Answer 3

谢谢你的回复，但是还是有问题
你的链接多了个&符号啊，你再检测下你的href。应该多了个&把&换成?

Answer 4

<a href='articles.do/delete?ID=${article.articleId}'>delete</a>
是这个，a标签中的单引号为双引号

Answer 5

<a href 双引号> </a>

Answer 6

改成双引号了
<td><a href="/articles/delete.do?ID=${article.articleId}">delete</a></td> 还是木有用
@Controller
@RequestMapping("/articles")
public class DeleteController {
@Autowired
  private ArticleService articleService;
 /**
   *  @RequestMapping(params = "actionMethod=delete", method = RequestMethod.POST)
public String delete(@RequestParam("id") final Long[] ids) {
List<GoodsBrand> brands = brandService.findDatasByIds(GoodsBrand.class,
ids);
if (brands != null && brands.size() > 0) {
brandService.deleteAll(brands);
}
return REDIRECTQUERYPATH;
}
   * @return
   */
  @RequestMapping(value="/delete")
  public String deleteService(@RequestParam("ID") final Integer ids) {
          System.out.println("hello");
  articleService.deleteService(ids);       return "redirect:/articles";
      
  }

Answer 7

<a href 双引号> </a>
改成双引号了
<td><a href="/articles/delete.do?ID=${article.articleId}">delete</a></td> 还是木有用
@Controller
@RequestMapping("/articles")
public class DeleteController {
@Autowired
  private ArticleService articleService;
 /**
   *  @RequestMapping(params = "actionMethod=delete", method = RequestMethod.POST)

你的链接多了个&符号啊，你再检测下你的href。应该多了个&眼花了。不过还是有问题
<a href 双引号> </a>

  }你的web.xml有配置过滤吗？

Answer 10

我眼睛都看花了。这个后&后面的参数没关系先。
先排查进入action再说。.do是你配置的后缀吗?

添加了do的过滤，是不是dispatcher里面还要加什么？你有其他的*.do请求到么？

没有，因为删除功能一直没有弄起来，就单独做了这个一个删除功能的controller,一直就是不能被捕获，html的后缀可以的，就是这个do不行
HTTP Status 404 - /articles/delete.do
地址是http://localhost:8080/articles/delete.do?ID=2
这个是jsp里的
<a href="/articles/delete.do?ID=${article.articleId}">delete</a>
-------------------
这个是controller
@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";       
  }
}
