Spring mvc error while binding date param

Question

I'm having a weird problem with a Spring MVC. I have a Controller method that accepts 2 date parameters as request parameters startDate and endDate. If I use a simple url with the 2 params like so :

http://localhost/myapp/videos?startDate=2013-05-10&endDate=2013-06-01.json

I get this error message :

[#|2013-05-27T17:39:01.711+0200|INFO|glassfish3.1.2|javax.enterprise.system.std.com.sun.enterprise.server.logging|_ThreadID=24;_ThreadName=Thread-2;|38386 [http-thread-pool-8080(5)] DEBUG org.springframework.web.servlet.mvc.support.DefaultHandlerExceptionResolver  - Resolving exception from handler [public java.util.List<Video> com.ufasoli.Videos.programs(com.ufasoli.filtering.SearchParams)]: org.springframework.validation.BindException: org.springframework.validation.BeanPropertyBindingResult: 1 errors

|#]

But as soon as I remove the .json like so :

http://localhost/myapp/videos?startDate=2013-05-10&endDate=2013-06-01

it all works fine...

This looks like a bug to me as the databinder should not take the url extension into account when binding the data to the controller or is this normal behavior?

Below is the controller method causing the problem :

 @RequestMapping(value = "/videos/", 
                 method = RequestMethod.GET, 
                 produces = MediaType.APPLICATION_JSON_VALUE)
    public List<Videos> videos( SearchParams searchParams) {

        return videosRepository.videos(searchParams);
    }

Here is my SearchParams class :

public class SearchParams extends BaseSearchParams implements Serializable{


    private static final long serialVersionUID = 1L;
    @DateTimeFormat(iso = ISO.DATE, pattern = "yyyy-MM-dd")
    private Date startDate;
    @DateTimeFormat(iso = ISO.DATE, pattern = "yyyy-MM-dd")
    private Date endDate;

     //Setters/Getters
}

I'm using Spring MVC 3.2.1.RELEASE

Any insight?

Thanks in advance

I think that the 'url extension' (if any) should be part of the path and belongs therefore before the query: http://localhost/myapp/videos.json?startDate=2013-05-10&endDate=2013-06-01. — nutlike

Oh god i'm so stupid of course the extension id part of the url. I got it confused with path variables Thanks for pointing it out.. — ufasoli
