I am using fastjson without importing the
maven dubbo-serialization-fastjson pom. Seems like it is included in Dubbo.
My consumer url is
:
reference.setUrl("dubbo://"+vpsIp+":20880/"+interfaceName+"?token=1234567&serialization=fastjson");
So as you can see i put the serialization directly in the URL because i
didn't find a way to configure it in java. (if you can help on this...)
"I think the the exception happened on the provider side when trying to
deserialize raw json data to java bean."
That's exactly what is happening.
"FastjsonObjectInput#readObject(Class<T> cls, Type type)"
This method is never called. The called method is "public <T> T
readObject(Class<T> cls)"
here is some screenshots to show you what is happening :

and finally when the error happen : https://i.imgur.com/66zfbUi.png
So yes it seems like when using fastjson it got a Map of JSONObject instead
of a List of OperatingSystemVersion.
If i remove from the consumer url the param serialization=fastjson
everything work fine.
