Multiple @PathVariable in Spring MVC

Question

Couldn't find an answer to this unfortunately so hoping someone can help.

In Spring MVC 3.1.0 here is my method:

@RequestMapping(value = "/{app}/conf/{fnm}", method=RequestMethod.GET)
public ResponseEntity<?> getConf(@PathVariable String app, @PathVariable String fnm) {
    log.debug("AppName:" + app);
    log.debug("fName:" + fnm);
            ...
            return ...
    }

I've seen some examples online and it appears there is no problem having multiple @PathVariables in theory.

However when I do it, both "app" and "fnm" contain the same value (which is whatever value was assigned to "app").

Really appreciate any insight someone may have to where I'm going wrong?

Thanks!

that should work, you sure you are calling it correctly ?

@RequestMapping(value = "/{app}/conf/{fnm}", method=RequestMethod.GET)
public ResponseEntity<?> getConf(@PathVariable("app") String app, @PathVariable("fnm") String fnm) {
   log.debug("AppName:" + app);
   log.debug("fName:" + fnm);
           ...
           return ...
  }

Basically path variables need to be specified with parentheses, in method arguments. Does this help?

Sorry, I should have specified that. I have tested without the variable name, with the variable name and also explicitly trying (value="_some_pathvarname"). All of which produce the same results :(

@user1389920 : Have you tried hardcoding request url with different values; For Example: /XYZ/conf/ABC and then check what gets mapped to the Controller? this is to verify that request is correctly formed...

Thanks, found the problem. fnm was being truncated so the test values looked the same... sorry bit of brain fade on this one. I have the correct regex now and it's working, thank you all for help!
