弹簧数据的Neo4j 4库方法返回1个元件

我从SDN 3移动到SDN 4和从Neo4j的2.3到3.0.1弹簧数据的Neo4j 4库方法返回1个元件

在新的依赖我的测试失败，并断言。它只返回一个，而不是3个节点。

@NodeEntity 
public class Decision extends Commentable { 

    private final static String CONTAINS = "CONTAINS"; 
    private final static String DEFINED_BY = "DEFINED_BY"; 
    private final static String VOTED_FOR = "VOTED_FOR"; 

    private String name; 

    @Relationship(type = DEFINED_BY, direction = Relationship.INCOMING) 
    private Set<Criterion> criteria = new HashSet<>(); 

.... 


@NodeEntity 
public class Criterion extends Authorable { 

    private final static String CONTAINS = "CONTAINS"; 
    private final static String DEFINED_BY = "DEFINED_BY"; 

    private String name; 

    private String description; 

    @Relationship(type = CONTAINS, direction = Relationship.INCOMING) 
    private CriterionGroup group; 

    @Relationship(type = DEFINED_BY, direction = Relationship.OUTGOING) 
    private Decision owner; 


@Test 
    public void testGetChildDecisionsSortedBySumOfCriteriaAvgVotesWeightWithCoefficients() { 
     User user = userService.createUser("test", "test", "[email protected]", null, null); 

     final Decision rootDecision1 = decisionDao.create("Root decision1", "Root decision 1 description", null, user); 

     final Criterion rootDecision1Criterion1 = criterionDao.create("rootDecision1Criterion1", "rootDecision1Criterion1", rootDecision1, user); 
     final Criterion rootDecision1Criterion2 = criterionDao.create("rootDecision1Criterion2", "rootDecision1Criterion2", rootDecision1, user); 
     final Criterion rootDecision1Criterion3 = criterionDao.create("rootDecision1Criterion3", "rootDecision1Criterion3", rootDecision1, user); 

     assertEquals(3, criterionDao.getCriteriaDefinedByDecision(rootDecision1.getId()).size());

库方法：

@Query("MATCH (d:Decision)<-[:DEFINED_BY]-(c:Criterion) WHERE id(d) = {decisionId} RETURN c") 
List<Criterion> getCriteriaDefinedByDecision(@Param("decisionId") Long decisionId);

什么可以这个问题的原因，以及如何解决它？

修订

我发现施工

public Criterion(String name, String description, Decision owner, User author) { 
     this.name = name; 
     this.description = description; 
     this.owner = owner; 
     setAuthor(author); 
    }

是不够的，为了创造ONE_TO_MANY协会SDN 4 ..我要以添加对象父集合添加额外的行也。

public Criterion(String name, String description, Decision owner, User author) { 
     this.name = name; 
     this.description = description; 
     this.owner = owner; 
     if (owner != null) { 
      owner.addCriterion(this); 
     } 
     setAuthor(author); 
    }

我在做什么错？

有同样的问题，请尝试从Criterion

@NodeEntity 
    public class Criterion extends Authorable { 

    private final static String CONTAINS = "CONTAINS"; 
    private final static String DEFINED_BY = "DEFINED_BY"; 

    private String name; 

    private String description; 

    @Relationship(type = CONTAINS, direction = Relationship.INCOMING) 
    private CriterionGroup group; 


}

去除DEFINED_BY @Relationship创建Criterion第一，然后将它们连接到Decision

谢谢，但我需要按照我的应用程序的业务逻辑这一领域。它在以前版本的SDN中完美运行..他们为什么要改变它？ – brunoid

不知道，有同样的问题。 –
