I have a generic class:
public class MsgServerData<T> {
...
public T content;
...
}
Previously the concrete implementation was MsgServerData<Invitation<String>>
and it worked fine, I was able to deserialize the object.
Now, I had to change the Invitation to have two parameters:
MsgServerData<Invitation<VCard,String>>.
And now it fails with the following exception:
com.fasterxml.jackson.databind.JsonMappingException: Can not deserialize
instance of java.lang.String out of START_OBJECT token
at [Source: N/A; line: -1, column: -1] (through reference chain:
co.tinode.tinodesdk.model.MsgServerData["content"])
i.e. it thinks the 'content' should be a String, not an Invitation.
Here is how I construct the data type for Jackson:
JavaType typeOfInvitation =
jacksonTypeFactory.constructParametricType(Invitation.class,
jacksonTypeFactory.constructType(VCard.class),
jacksonTypeFactory.constructType(String.class)));
JavaType typeOfDataPacket =
jacksonTypeFactory.constructParametricType(MsgServerData.class,
typeOfInvitation);
Where is my mistake?
Thanks!
