使用斜杠分隔的多个(两个)通配符的 Servlet 映射 [英] Servlet mapping with multiple (two) wildcards separated by slash

问题描述

我正在尝试映射一个同时匹配两个

I am trying to map a servlet pattern that matches both

/server/abcDef/1432124/adfadfasdfa 

和

/server/abcDef/abcd/12345

值 '1432124' 和 'abcd' 不是固定的，可能是多个值.所以基本上我需要匹配 /abcDef/*/* —— 只有 abcDef 是固定的.

The values '1432124' and 'abcd' are not fixed and could be a multitude of values. So essentially I need to match against /abcDef/*/* -- only the abcDef is fixed.

有没有办法让我映射这个?我真的在寻找类似以下的东西:

Is there a way for me to map this? Really I am looking for something like the following:

<servlet-mapping>
    <servlet-name>abcDefServlet</servlet-name>
    <url-pattern>/server/abcDef/*/*</url-pattern>
</servlet-mapping>

推荐答案

根据 Servlet 规范，以/*"结尾的 URL 模式将匹配到前面路径的所有请求.因此，按照您的操作方式，您必须输入以下 url 才能访问 abcDefServlet:

According to the Servlet Specification, URL patterns ending with "/*" will match all requests to the preceding path. So, in the way you were doing it, you'd have to enter the following url to get to abcDefServlet:

http://myapp.com/server/abcDef/*/<wildcard>

您可以做的是在一个 servlet 映射中添加多个 URL 模式.例如:

What you can do though is add multiple URL patterns in one servlet mapping. E.g:

<servlet-mapping>
   <servlet-name>abcDefServlet</servlet-name>
   <url-pattern>/server/abcDef/1432124/*</url-pattern>
   <url-pattern>/server/abcDef/abcd/*</url-pattern>
</servlet-mapping>

更新:

由于 1432124 和 abcd 不是固定值，您可以安全地添加以下映射:

Since 1432124 and abcd are not fixed values, you can safely add the following mapping:

<servlet-mapping>
   <servlet-name>abcDefServlet</servlet-name>
   <url-pattern>/server/abcDef/*</url-pattern>
</servlet-mapping>

然后使用以下函数处理 servlet 本身内 abcDef 之后的任何值:

And then treat whatever values that come after abcDef inside the servlet itself, with the following function:

req.getPathInfo()
