你可以添加自己的过滤器到列表中，使用custom-filter过滤元件和这些名字来指定你的过滤器应该出现在的位置之一：
<http>
<custom-filter position="FORM_LOGIN_FILTER" ref="myFilter" />
</http>
<beans:bean id="myFilter" class="com.mycompany.MySpecialAuthenticationFilter"/>
你也可以使用after和before属性来让你的过滤器插入到列表中的其他过滤器的前面和后面。FIRST和LAST可以用在position属性来设置你希望将你的过滤器插入到整个列表的前面或者后面。
