Quarkus RestEasy Reactive Not Exploding List Type Query Parameter

[The-Funk]

I have a query parameter declared as follows in my method (@restquery String[] someList)

However when I go to reference this data, the array is converted to an array of 1 String.

Am I doing something wrong here? Is it because of how I'm entering my query parameters? I tend to use the shorthand comma separated value notation and only ref the parameter name one time in the URL. I prefer this in order to keep the URL shorter. For instance www.example.com?someList=value1,value2,value3 as opposed to www.example.com?someList=value1&someList=value2&someList=value3

Have you tried using a List instead of an Array: @RestQuery List<String> someList ?

Both List and String[] work when supplying multiple values via the ?k1=v1&k1=v2 method of supplying a query parameter with multiple values, however neither explode comma separated values when provided like this ?k1=v1,v2.

That's how JAX-RS works unfortunately

Is there no support for the shorthand notation at all? How do people provide comma separated lists in their URLs? The shorthand is much more efficient, I try to use it whenever possible. Right now I'm just manually exploding the results.

Manual is the only way

Just for documentation, if someone else stumbles over this problem and request here:

Here is the discussion #29500 leading to this really nice improvement #29528 enabling

@GET
public String hello(@QueryParam("foo") @Separator(",") List<String> foo) {}

Well that's cool! 😃
