Spring Rest - 實體圖註解忽略並完成實體

使用Jersey開發REST服務時，我發現實體圖註釋被忽略，我得到完整的對象。下面的代碼。Spring Rest - 實體圖註解忽略並完成實體

@Entity 
@Table(name = "CONCERN") 
@XmlRootElement 
@EntityListeners(ConcernListener.class) 
@NamedEntityGraph(name="concern.search", attributeNodes={ 
     @NamedAttributeNode("referenceId"), 
     @NamedAttributeNode("name"), 
     @NamedAttributeNode("mobileNumber"), 
     @NamedAttributeNode("email"), 
     @NamedAttributeNode("concernDetail"), 
     @NamedAttributeNode(value = "concernType", subgraph = "concernType")}, 
     subgraphs = @NamedSubgraph(name = "concernType", attributeNodes = {@NamedAttributeNode("descEn"),@NamedAttributeNode("descAr")}) 
    ) 
public class Concern { 

    @Id 
    @Basic(optional = false) 
    @GeneratedValue(strategy = GenerationType.AUTO, generator = "TXN_REPORT_CONCERN_SEQ") 
    @SequenceGenerator(name = "CONCERN_SEQ", sequenceName = "TXN_REPORT_CONCERN_SEQ", allocationSize = 0) 
    private Long id; 

    @Basic(optional = false) 
    @Size(min = 1, max = 30) 
    @Column(name = "REFERENCE_ID", nullable = false, length = 30) 
    private String referenceId; 
.......

庫代碼

public interface ReportConcernRepository extends CrudRepository<Concern, Long> { 


    @EntityGraph(value = "concern.search", type = EntityGraphType.FETCH) 
    @Query("SELECT c FROM Concern c") 
    public List<Concern> readAll(); 
}

澤西REST服務

@GET 
    @Produces(MediaType.APPLICATION_JSON) 
    @Path("findAll") 
    public List<Concern> getAllConcerns(){ 
     return reportConcernService.getAllConcerns(); 
    }

輸出JSON

如可以看到的整個實體已經被加載，而不是屬性。可能是什麼原因？

我可能爲晚會太晚了，但我有類似的問題。對你描述的任務使用實體圖似乎很自然，但不幸的是這不起作用。原因是傑克遜在序列化過程中調用了實體中的每個吸氣器，所以在一天結束時，你在Entity Graph中包含哪些屬性並不重要（其他屬性只是延遲加載），因爲Jackson會得到它們無論如何。我發現只有一個簡單的解決方案：@JsonIgnore絕對不像實體圖那樣靈活。另外，並非所有JPA ORM都可以用於100％實體圖形支持，請參閱https://hibernate.atlassian.net/browse/HHH-9270
