Using Regular Expressions to Evaluate Path Variables in a Spring MVC controller

amirkibbar on ‎04-22-2013 10:47 PM

Sometime you may want to process the URI in the request and assign values to several path variables instead of a single one. This can easily be achieved with regular expressions on the URI itself within the @RequestMapping.


The syntax is {varName:regex} for the parsed URI path variable. For example suppose we want to provide an HTTP GET over this URI: /jars/log4j-1.2.16.jar, but we want to allow any jar name, version and extension with the format name-version.extension and we also want to get each of these path variables in a separate argument in our controller handler method. We can do it this way:



public final class MyController {
     public void handle(@PathVariable String artifact, @PathVariable String version, @PathVariable String extension) {

 Simple and useful.
