I have an issue when trying to put in place the “selectable entity filtering”. I have an Abstract class like following one:

// In your Pom

org.glassfish.jersey.ext

jersey-entity-filtering

....

//Somewhere in resourceConfig: Register entity-filtering selectable feature.

register(SelectableEntityFilteringFeature.class);

property(SelectableEntityFilteringFeature.QUERY_PARAM_NAME, "select");

register(JacksonFeature.class);

…..

Before registering the “selectable entity filtering” all was working fine, I tested that a lot.

And after registering “selectable entity filtering” I have the following error:

[2016-02-15 17:25:36] - DEBUG EntityMapper:116 [http-bio-8080-exec-3] Preparing query INSERT INTO

[2016-02-15 17:25:43] - ERROR JsonMappingExceptionMapper:29 [http-bio-8080-exec-3] Malformed Json!

It seems that the issue comes from the

StdSerializer.findPropertyFilter(StdSerializer.java:285)

protected PropertyFilter findPropertyFilter(SerializerProvider provider,

Object filterId, Object valueToFilter)

throws JsonMappingException

{

FilterProvider filters = provider.getFilterProvider();

// Not ok to miss the provider, if a filter is declared to be needed.

if (filters == null) {

throw new JsonMappingException("Can not resolve PropertyFilter with id '"+filterId+"'; no FilterProvider configured");

}

PropertyFilter filter = filters.findPropertyFilter(filterId, valueToFilter);

// But whether unknown ids are ok just depends on filter provider; if we get null that's fine

return filter;

}

I don’t understand why the filtering is activated even in POST requests ? The strange thing is I didn’t put the “select” query parameter in the request!

Could you please help ?

It seems that when you are using the SelectableEntityFilteringFeature and if you are putting Collection as an Entity in Response then you will get a JsonMappingException. For me it is a bug. The work around is you should encapsulate your collection into GenericEntity to be able to be serialized by Jersey-Jackson.

return Response.status(Status.OK)

.entity(new GenericEntity>(entityIDs) {}).build();

// Use GenericEntity to avoid JsonMappingException because of the new flow with Filtering
