I'm back with a quick post (with more to come soon).
I was in the middle of upgrading my little test project to a newer version of Spring Data Neo4j and Neo4j itself when I came across a few little points that others might find useful (though it should be noted that Neo4j is set to release 2.0 very soon and is currently doing milestone releases).
I upgraded SDN to 2.3.1.RELEASE and Neo4j (all aspects of it, including Cypher) to 1.9.4.
Here are a couple "gotchas" I encountered:
It would seem that CGLIB has been moved out of one of the Neo4j or SDN dependencies; however, I also found that--with the SDN/Neo4j combination I'm using--that a specific version is required, namely 2.2.2.
Adding this bit into my POM fixed things up nicely:
No Bean Named 'graphDatabaseService' is Defined
This one was fun. As confirmed in
this Neo4j forum thread
(which actually uses Neo4j 1.7 and SDN 2.1.0.Build-Snapshot), when configuring Neo4j in an application context, the bean ID for the graph database service (whether it's embedded or from a server)
be "graphDatabaseService", similar to this:
<constructor-arg index="0" value="http://someserver:7474/db/data" />
If this little nuance is overlooked, you could very well see exceptions when, say, starting up your application server with your SDN-based application.
In my case, Maven compiled my WAR file just fine, but, starting up Tomcat produced a slew of exceptions.
It would seem that this is an ongoing issue, though, perhaps it's a necessary change from the SDN folks. We'll just have to see!
Hopefully some people find these tidbits useful.
We'll see you on the next post!
