Spring MVC referencing params variable from RequestMapping

Question

I have the method below:

@RequestMapping(value = "/path/to/{iconId}", params="size={iconSize}", method = RequestMethod.GET)
public void webletIconData(@PathVariable String iconId, @PathVariable String iconSize, HttpServletResponse response) throws IOException {
    // Implementation here
}

I know how to pass the variable "webletId" from the RequestMapping using the @PathVariable, but how do I reference the variable "iconSize" from params?

Thanks a lot.

Answer 1

Use @RequestParam:

@RequestMapping(value = "/path/to/{iconId}", method = RequestMethod.GET) 
public void webletIconData(@PathVariable String iconId, 
    @RequestParam("size") String iconSize, 
    HttpServletResponse response) throws IOException { ... }
