I'm trying to load a WFS Layer in QGIS. I requst the data from my GeoServer and would like to import the data as GeoJSON.
I can export my data in the layer preview section as GeoJSON. Everything works fine.
But i am unable to display my data in QGIS. I tried to add the "&outputFormat=application%2Fjson" at the GetFeature request.
I think my issue belongs to this similar question but the author did not answer the question of @nmtoken if the WFS GetCapabilities request for the service is listed GeoJSON as a GetFeature ResultFormat.
In my case, the format is listed.
Here is the output of the GetCapabilities request:
<ows:Operation name="GetFeature">
.
.
<ows:Parameter name="outputFormat">
<ows:AllowedValues>
<ows:Value>application/gml+xml; version=3.2</ows:Value>
<ows:Value>GML2</ows:Value>
<ows:Value>KML</ows:Value>
<ows:Value>SHAPE-ZIP</ows:Value>
<ows:Value>application/json</ows:Value>
<ows:Value>application/vnd.google-earth.kml xml</ows:Value>
<ows:Value>application/vnd.google-earth.kml+xml</ows:Value>
<ows:Value>csv</ows:Value>
<ows:Value>gml3</ows:Value>
<ows:Value>gml32</ows:Value>
<ows:Value>json</ows:Value>
<ows:Value>text/xml; subtype=gml/2.1.2</ows:Value>
<ows:Value>text/xml; subtype=gml/3.1.1</ows:Value>
<ows:Value>text/xml; subtype=gml/3.2</ows:Value>
</ows:AllowedValues>
</ows:Parameter>
.

Please give me a helping hand here, maybe it's not possible to load my data as GeoJSON through a WFS because it will always provide the data as XML? I tested it with WFS 1.0.0, 1.1.0 and 2.0.0
Versions:
QGIS 3.2.
GeoServer 2.12.1

I had to deviate from the orignal plan to load my data as GeoJSON through a WFS. As @ian-turton mentioned above it makes no sense to use GeoJSOn here because GeoServer and QGIS doing a good job with GML.
So I tried the GML Application Schema toolbox QGIS plugin recommended by @user30184.
My configuration on the GeoServer:
Steps you have to do within the plugin:
As you can see in the screenshot, my complex features are stored in three separate layer (left). The features attributes table (right) shows the complex relationships.
