Add support for the Neo4j Graph Query Language "Cypher" [DATAGRAPH-91]

[spring-projects-issues]

Michael Hunger opened DATAGRAPH-91 and commented

Neo4j 1.4.M04 released the first version of a Graph Query Language.

Support for this Query Language has been added at the following places:

• a separate QueryExecutor Helper class
• introduced methods in the NodeEntities
• dynamic field with @GraphQuery annotation
• allows repository methods with @GraphQuery annotation

Example, NodeEntity-field:

@GraphQuery("start me=(%d) match (me)-[:works_at]->(company)<-[:works_at]-(colleague) return colleague")
Iterable<Person> colleagues;

Example, Repository:

interface PersonRepository extends GraphRepository<Person> {
   @GraphQuery("start person=(%d) match (person)-[:boss]->(boss) return boss")
   Person findBoss(Person developer);
}

Affects: 1.1 M1
