跟着网上的视频敲示例代码，然后就报错了...
Web页面代码：

<!-- REST PUT -->
<form action="test/restPut/2" method="post">
  <input type="hidden" name="_method" value="PUT"/>
  <input type="submit" value="REST PUT" />
</form>

Controller代码：

@Controller
@RequestMapping("/test")
public class SpringRequestMapping
{
    // 成员属性；
    private final String SUCCESS = "success";
    
    /**
     * 功能描述：测试RESTful PUT；
     * @param id
     * @return
     */
    @RequestMapping(value = "/restPut/{id}", method = RequestMethod.PUT)
    public String restPut(@PathVariable("id") Integer id)
    {
        System.out.println("RESTful PUT：" + id);
        return SUCCESS;
    }
    
}

web.xml

<filter>
    <filter-name>HiddenHttpMethodFilter</filter-name>
    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>    
  
<filter-mapping>
  <filter-name>HiddenHttpMethodFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

新手求助，麻烦大神指点一二，问题出在哪了？？？
