Is there way to query "url-pattern" property from Java code of servlet filter?

Is there way to obtain "url-pattern" property from Java code of servlet filter ? I know I can pass same pattern in servlet init params but it se开发者_JAVA百科ems redundant.

Thanks!

In servlet 3.0 - yes:

public void init(FilterConfig cfg) {
   List<String> mappings = 
       cfg.getServletContext().getFilterRegistration(cfg.getFilterName())
          .getUrlPatternMappings();
}
