I'm starting to work with Neo4j and spring data.
I can do a get on the data base but can not make a set.
When I try to use the save method happens this error. It seems to be because of the unrecognized field by jackson. I looked for solutions but nothing worked.
Can anybody help me?

Looks like you're using Neo4j 3? If so, the version of SDN you're using is probably incompatible. Neo4j 3.0 is compatible with these:
