  <!--spring mvc过滤器： 浏览器form表单只支持GET与POST请求，
  而DELETE、PUT等method并不支持，spring3.0添加了一个过滤器，
  可以将这些请求转换为标准的http方法，使得支持GET、POST、PUT与DELETE请求，
  该过滤器为HiddenHttpMethodFilter。-->
  <filter>
    <filter-name>hiddenHttpMethodFilter</filter-name>
    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>hiddenHttpMethodFilter</filter-name>
