Question

我在客户的项目中使用Javers 5.5.2，问题出在下一个：我有2个实体：交通工具和情感。感情是车辆的孩子。

当我保存并提交车辆实体时，我希望Javers为我提供有关affecation的信息，但只返回受影响的ID。

/**
 * A Vehicule.
 */
@Entity
@Table(name = "vehicule")
@Document(indexName = "vehicule")
public class Vehicule implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator 
 "sequenceGenerator")
    @SequenceGenerator(name = "sequenceGenerator")
    private Long id;

    @Pattern(regexp = "^[A-Z]$")
    @Column(name = "categorie_assurance")
    private String categorieAssurance;

    @ManyToOne
    @JsonIgnoreProperties("vehicules")
    private Affectation affectation;



**
 * A Affectation.
 */
@Entity
@Table(name = "affectation")
@Document(indexName = "affectation")
public class Affectation implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "sequenceGenerator")
    @SequenceGenerator(name = "sequenceGenerator")
    private Long id;


    @Column(name = "code", nullable = false)
    private String code;


    @Column(name = "commune", nullable = false)
    private String commune;


    @Column(name = "libelle", nullable = false)
    private String libelle;

这是我从三叶草中进行审核的端点，我正在使用查找更改。

@RequestMapping("/vehicule/{id}/commits")
    public ResponseEntity<List<ChangesByCommitAndChanges>> getVehiculeChangesByCommit(@PathVariable Integer id,
                                                                                      @RequestParam Optional<String> param) {
        QueryBuilder jqlQuery = QueryBuilder
            .byInstanceId(id, Vehicule.class)
            .withNewObjectChanges(false)
            .withChildValueObjects()
            .limit(10);
        jqlQuery = param.isPresent() ? jqlQuery.withChangedProperty(param.get()) : jqlQuery;
        return ResponseEntity.ok().body(groupChangesByCommit(javers.findChanges(jqlQuery.build())));
    }

此端点返回以下审核：

  - 'numeroCommande' value changed from '11-723' to '11-723aef'
  - 'numeroMarche' value changed from '250/10' to '250/10efae'
  - 'observations' value changed from 'efef' to 'efefefaef'

您可以在这些日志中看到，情感仅返回其ID，而不返回其他属性值（代码，公社，libelle）。

如何使用javers和hibernate实体深入了解子属性？
