I know I cannot use regular expressions for the <url-pattern>
of a filter-mapping, but is it possible to use a directory pattern to specify any url containing the word myuniqws
as in:
https://my.hostname.org/myuniqws/myport/soap?wsdl
I am thinking of perhaps this would be the correct syntax:
<url-pattern>/*myuniqws*</url-pattern>
but I have not been able to find documentation for the exact rule of Tomcat's <url-pattern>
syntax.
Will the above regex work as I desire?
Update:
Thanks to the answer below, I discovered the following section in the Java Servlet Specification, which basically answers my questions.
12.2 Specification of Mappings
In the Web application deployment descriptor, the following syntax is used to define mappings:
- A string beginning with a ‘/’ character and ending with a ‘/*’ suffix is used for path mapping.
- A string beginning with a ‘*.’ prefix is used as an extension mapping.
- The empty string ("") is a special URL pattern that exactly maps to the application's context root, i.e., requests of the form
http://host:port/<contextroot>/
. In this case the path info is ’/’ and the servlet path and context path is empty string (““). - A string containing only the ’/’ character indicates the "default" servlet of the application. In this case the servlet path is the request URI minus the context path and the path info is null.
- All other strings are used for exact matches only.
If the effective web.xml
(after merging information from fragments and annotations) contains any url-patterns that are mapped to multiple servlets then the deployment must fail.
