java - tomcat(7、8)自定义403页面不跳转,且与禁用HTTP方法冲突。

一个B/S系统进行安全测评,返回结果要求禁用一些不常用的HTTP方法(PUT、DELTETE、OPTIONS等),按照网上的方法,在应用的web.xml的最后添加如下代码:

<!--安全配置 start -->
<security-constraint>
    <web-resource-collection>
        <url-pattern>/*</url-pattern>
        <http-method>PUT</http-method>
        <http-method>DELETE</http-method>
        <http-method>HEAD</http-method>
        <http-method>OPTIONS</http-method>
        <http-method>TRACE</http-method>
    </web-resource-collection>
    <auth-constraint/>
</security-constraint>
<login-config>
    <auth-method>BASIC</auth-method>
</login-config>
<!--安全配置 end-->

上面的几个HTTP方法有效被禁用,但请求会跳转到tomcat的403页面,如下图:

按照测试要求,上图红色部分暴露的tomcat的版本,应该自定义403页面以屏蔽版本,于是在上面的安全配置后添加如下代码:

<error-page>
    <error-code>404</error-code>
    <location>/sys/404.html</location>
</error-page>
<error-page>
    <error-code>403</error-code>
    <location>/sys/403.html</location>
</error-page>

结果是。。。。。。。。。。根本没用,并且HTTP的限制也不起作用了。
试了一番,发现404,500等error-code都正常,并且与HTTP限制不冲突。
只要加上403,HTTP方法就限制不了,并且也不会跳转到自定义的403.html。

完整web.xml如下:
