Provide builtin ParamConverter* classes for multi valued params --------------------------------------------------------------- Key: WFLY-11242 URL: https://issues.jboss.org/browse/WFLY-11242 Project: WildFly Issue Type: Feature Request Reporter: Marek Kopecký Assignee: Ron Sigal Priority: Major Fix For: 15.0.0.Alpha1 This is follow up for RESTEASY-1746 and RESTEASY-1566. In these feature jiras, users needs to prepare custom ParamConverter* classes in deployment. This feature should provide builtin ParamConverter* universal classes. Some PoC is in [this commit|https://github.com/marekkopecky/Resteasy/commit/08e0eb6de206085593...] Suitable annotations for end-point can parametrize converter behaviour. [~ron_sigal]'s proposal: {noformat}Maybe annotations in > public <T> ParamConverter<T> getConverter(Class<T> rawType, Type genericType, Annotation[] annotations; could be used to generalize. E.g., public Response conversion1(@QueryParam @Separator("&") List<MultiValueParamBuiltinMyObject1> q); Even more general could be something like public Response conversion1(@QueryParam @MultiSyntax(<regular expression/>) List<MultiValueParamBuiltinMyObject1> q) {{noformat}
