I was hoping to avoid making two threads this week, but, oh well. :)
This question applies to the SDN 3.0.1 release.
I understand the switch to label-based indices and that @Indexed invokes
just that. For legacy indices, indexType should be set to SIMPLE (or
FULLTEXT) with an optional indexName.
So, I think I might be missing something in my understanding of how SDN has
utilized label-based indices, or something with respect to how SDN uses
Neo4jTemplate, and am looking for some clarification.
I have a POJO annotated thusly:
@NodeEntity
public class Platform {
@GraphId
private Long nodeId;
@Indexed
private String platformId;
...
Now, in some other code elsewhere, I'm having a Neo4jTemplate instance
perform a ".lookup(...) like so:
Platform platform = template.lookup(Platform.class, "platformId",
platformId).to(Platform.class).singleOrNull();
platformId holds a legal value ("1", in fact).
I get an exception thrown in IndexProvider (specifically in
IndexProviderImpl) in "getIndex" like so:
if (providedIndexName==null ||
providedIndexName.equals(defaultIndexName)) {
throw new IllegalStateException("Index name for "+property+"
must differ from the default name: "+defaultIndexName);
}
Now, providedIndexName *is* null since none was annotated in the POJO. The
defaultIndexName is, unsurprisingly, "Platform". In fact, the "property"
parameter into the method has the value "class java.lang.String platformId
rel: false idx: true" and the instanceType parameter is "class
com.proj.vonneumanns.entities.Platform". Seems about right.
So, should I be using the .lookup(...) method? Or am I misunderstanding
with respect to how I should be annotating my POJO above? I do not want to
use the legacy indices, so I don't want to specify indexName or indexType,
and based on what I've seen so far from the blogs and updates, the POJO is
annotated correctly for the latest SDN (i.e. 3.0.1).
Is it possible to have several indexed attributes in a POJO that all use
the new label-based indices (i.e. none of them would use the legacy
indices)?
I've checked the following links for possible solutions but don't think
they're quite the same issue/matter:
http://stackoverflow.com/questions/22111928/index-name-for-class-java-lang-string-name-rel-false-idx-true-must-differ-from
https://jira.spring.io/browse/DATAGRAPH-437
http://stackoverflow.com/questions/22022691/sdn-neo4j-3-0-release-index-strategy/22084251#22084251
...and the respective related links.
Any insight to help clarify would be greatly appreciated. Everything else
seems to be going decently so far in my diving into SDN 3.0.1 and several
other items I've explored work as expected.
Thanks in advance!
