URL映射不适用于servlet

我认为这是一个奇怪的问题。

使用与servlet相同的映射,一个url工作,另一个不工作:

    <servlet-mapping>
    <servlet-name>UL_Admin</servlet-name>
       <url-pattern>/universal_listings_administration/*</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
      <servlet-name>Create_New_Site</servlet-name>
      <url-pattern>/universal_listings_administration/sites/new_site/*</url-pattern>
    </servlet-mapping>
   <servlet-mapping>
    <servlet-name>Create_New_Site</servlet-name>
    <url_pattern>/universal_listings_administration/sites/delete_site/*</url_pattern>
   </servlet-mapping>

Create_New_Site适用于/ universal_listings_administration / sites / new_site / *,但不适用于/ universal_listings_administration / sites / delete_site / *

当进入/ universal_listings_administration / sites / delete_site / *时,网站只需转到UL_Admin !!!

我已经更改了网址的顺序,但获得了相同的结果。我在不同的浏览器上试过这个,认为它可能是一个缓存问题,但每次都得到相同的结果。

有没有人知道这里发生了什么?

我认为唯一可能的另一件事是我的过滤器还是什么?我看了一眼,但过滤器似乎一切正常。无论如何,这是我在web.xml中的安全性和过滤器设置

    <security-constraint>
        <web-resource-collection>
            <url-pattern>/universal_listings_administration/*</url-pattern>
        </web-resource-collection>
        <auth-constraint>
            <role-name>admin</role-name>
        </auth-constraint>
    </security-constraint>
    <security-constraint>
        <web-resource-collection>
            <url-pattern>/jsps/admin/*</url-pattern>
        </web-resource-collection>
        <auth-constraint>
            <role-name>admin</role-name>
        </auth-constraint>
    </security-constraint>
    <security-constraint>
        <web-resource-collection>
            <url-pattern>/stylesheets/admin/*</url-pattern>
        </web-resource-collection>
        <auth-constraint>
            <role-name>admin</role-name>
        </auth-constraint>
    </security-constraint>

更新:

我做了一些调试,我确定我要去正确的URL,(从web.xml复制,粘贴),这是我在请求到达第一个过滤器时得到的(比较create_site和delete_site :

create_site: http://www.example.com:8888/universal_listings_administration/sites/new_site/ _pathInfo:“/” _requestURI:“/ universal_listings_administration / sites / new_site /” _servletPath:“/ universal_listings_administration / sites / new_site” _uri:“/ universal_listings_administration / sites / new_site /”

delete_site: http://www.example.com:8888/universal_listings_administration/sites/delete_site/ _pathInfo:“/ sites / delete_site /” _requestURI:“/ universal_listings_administration / sites / delete_site /” _servletPath:“/ universal_listings_administration” _uri:“/ universal_listings_administration / sites / delete_site /”

我想我现在必须弄明白为什么_pathInfo和_servletPath完全不同......

映射看起来很好。这些症状至少表明实际 URL错误或某些过滤器或servlet在到达servlet之前或之后更改了请求/响应目标。

如果没有调试/记录所有servlet和过滤器来跟踪整个代码中HttpServletRequest实例的执行路径,这个问题很难确定。由于我们无法访问您的代码/环境来重现问题,因此完成此任务完全取决于您。

我认为我的web.xml中的url-mapping肯定有问题。必须非常微妙,只能通过复制和粘贴另一个servlet映射并更改URL来修复。

可能的原因:使用德语键盘,并在英语和德语之间切换???

答案 2 :(得分:0)

看起来像一个简单的拼写错误,应该是<url-pattern>,而不是<url_pattern>
