结合Neo4j，Spring数据和Neo4j谓词

Question

I found org.neo4j.helpers.Predicate interface. I use Neo4j and Spring Data. I have a repository like this:

public interface RelationRepository extends GraphRepository<Relation> {
}

But when I want to call relationRepository.findAll(new MyPredicate()) it does not work. There is no method created for consuming predicates. Is there any way to combine it all together?

Answer 1

You can use QueryDSL predicates with QueryDslRepository.

see this section: http://docs.spring.io/autorepo/docs/spring-data-neo4j/3.3.0.M1/reference/html/#reference_programming-model_repositories

or the tests:
