    这是我的SDN 5关系实体: 

    @RelationshipEntity(type = "HAS_VALUE_ON")
public class RelationshipValue {

    @Id
    @GeneratedValue
    private Long id;

    @StartNode
    private Decision decision;

    @EndNode
    private Valuable valuable;

    @Index(unique = false)
    private Object value;

    public Object getValue() {
        return value;
    }

    public void setValue(Object value) {
        this.value = value;
    }

}

    一切都很好,但当我尝试将逻辑转换为新的动态时 @Properties : 

    @RelationshipEntity(type = "HAS_VALUE_ON")
public class RelationshipValue {

    public static final String VALUE_PROPERTY_NAME = "value";

    @Id
    @GeneratedValue
    private Long id;

    @StartNode
    private Decision decision;

    @EndNode
    private Valuable valuable;

    @Properties(allowCast = true)
    private Map<String, Object> valueProperties = new HashMap<>();

    public Object getValue() {
        return valueProperties.get(VALUE_PROPERTY_NAME);
    }

    public void setValue(Object value) {
        valueProperties.put(VALUE_PROPERTY_NAME, value);
    }

}

    我的测试失败,出现以下错误: 

    org.springframework.dao.InvalidDataAccessApiUsageException: Could not map key=valueProperties.value, value=[Ljava.lang.Object;@52bef30b (type = class [Ljava.lang.Object;) because it is not a supported type.; nested exception is org.neo4j.ogm.exception.core.MappingException: Could not map key=valueProperties.value, value=[Ljava.lang.Object;@52bef30b (type = class [Ljava.lang.Object;) because it is not a supported type.

    这可能是因为不支持数组作为映射值。

    从数组切换到列表作为 setValue 方法应该解决这个问题。
