Servlet mapping with multiple (two) wildcards separated by slash
提问by Sai
I am trying to map a servlet pattern that matches both
我正在尝试映射与两者都匹配的 servlet 模式
/server/abcDef/1432124/adfadfasdfa
and
和
/server/abcDef/abcd/12345
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 abcDefis fixed.
值 '1432124' 和 'abcd' 不是固定的，可以是多个值。所以基本上我需要匹配/abcDef/*/*- 只有abcDef是固定的。
Is there a way for me to map this? Really I am looking for something like the following:
有没有办法让我映射这个？我真的在寻找类似以下的东西：
<servlet-mapping>
<servlet-name>abcDefServlet</servlet-name>
<url-pattern>/server/abcDef/*/*</url-pattern>
</servlet-mapping>

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 urlto get to abcDefServlet:
根据Servlet 规范，以“/*”结尾的 URL 模式会将所有请求匹配到前面的路径。因此，按照您的操作方式，您必须输入以下URL才能访问 abcDefServlet：
http://myapp.com/server/abcDef/*/<wildcard>
What you can do though is add multiple URL patterns in one servlet mapping. E.g:
您可以做的是在一个 servlet 映射中添加多个 URL 模式。例如：
<servlet-mapping>
<servlet-name>abcDefServlet</servlet-name>
<url-pattern>/server/abcDef/1432124/*</url-pattern>
<url-pattern>/server/abcDef/abcd/*</url-pattern>
</servlet-mapping>
Update:
更新：
Since 1432124and abcdare not fixed values, you can safely add the following mapping:
由于1432124和abcd不是固定值，您可以安全地添加以下映射：
<servlet-mapping>
<servlet-name>abcDefServlet</servlet-name>
<url-pattern>/server/abcDef/*</url-pattern>
</servlet-mapping>
And then treat whatever values that come after abcDefinside the servlet itself, with the following function:
然后abcDef使用以下函数处理 servlet 内部后面的任何值：
req.getPathInfo()
