春データのNeo4j 5とダイナミック@Properties InvalidDataAccessApiUsageException

Question

は、これは私のSDN 5関係の実体である：

@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); 
    } 

} 

：

@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; 
    } 

} 

すべてが正常に動作しているが、私は新しい動的@Propertiesにロジックを変更しようとすると、

私のテストは、次のエラーで失敗します。

動的な@Propertiesで同じ正しい動作（最初のコードスニペットの場合と同じ）をエミュレートする方法はありますか？

Answer 1

配列がMap値としてサポートされていない可能性があります。

setValueメソッドへの引数として配列からリストへの切り替えは、この問題を解決するはずです。
