Sergey Beryozkin commented on CXF-6941:
---------------------------------------
I'm not comfortable about supporting it:
- treating a query parameter value with commas in it as a multivalued property
*by default* effectively makes it JAX-RS non-compliant.
- it is a performance hit - every query parameter will need to be parsed, after
the whole query has been parsed because it will need to work not only for
arrays but only for spec mandated List and Set and for single values too, for
example, if you have "a=2&a=3" and declare a String only then it will report
the 1st value, '2'. Therefore if you have "a=1,2,3" then it has to work for all
the types supported by JAX-RS.
- it is a classical case of the developers thinking that the same (their own
framework) will listen on the other end and as such it affects the
interoperability as I've already said. Supporting it at the feature level makes
them think that it will work end to end but it won't if the server is written
as a Servlet - HttpServletRequest will not understand it.
I can only consider supporting it optionally: a property will be introduced
which, if set, will enable the runtime to treat a property with a
comma-separated value as a multi-valued property. It will be documented as a
CXF extension

> http://stackoverflow.com/questions/11889997/how-to-send-a-array-in-url-request
> Spring MVC and PHP support send comma separated array in the url request:
> http://localhost:8080/MovieDB/GetJson?name=Actor1,Actor2,Actor3&startDate=20120101&endDate=20120505
> @RequestMapping(value = "/GetJson", method = RequestMethod.GET)
> public void getJson(@RequestParam("name") String[] ticker,
> @RequestParam("startDate") String startDate, @RequestParam("endDate") String
> endDate) {
> //code to get results from db for those params.
> }
> Now jax-rs only support below:
> http://localhost:8080/JerseyPojo/jaxrs/BasicResource/test?nameList=xx&nameList=xxx&nameList=ddd
> @Path("/test")
> @GET
> public String getQueryList([~getadr...@gmail.com]
> When we migrate from Spring MVC to jax-rs, found problem.
