hibernate - 如何使惰性关系保持在休眠状态下反应

Question

我正在使用带有休眠反应的 Quarkus，一旦我添加了 @OneToMany 注释，我就无法使我的实体持续存在。我向您展示我的所有代码：

实体一：树：

@Entity(name = "Tree")
@Table(name = "tree")
public class Tree{
  
  @Id
  @Column(length = 50, unique = true)
  public String name;

  @OneToMany(mappedBy = "owner", cascade = CascadeType.ALL, orphanRemoval = true, fetch = FetchType.LAZY)
  @JsonManagedReference
  private List<Fruit> treeFruits;

  public void addFruits(Fruit fruit) {
    treeFruits.add(fruit);
    fruit.setOwner(this);
  }

  public void addFruits(List<Fruit> fruits) {
    treeFruits.addAll(fruits);
    fruits.stream().forEach(f->f.setOwner(this) );
  }    


// Getters and setters removed

实体二：水果：

@Entity
@Table(name = "fruit")
public class Fruit {

  @Id
  @Column(length = 50, unique = true)
  public String name;

  @Column(length = 200)
  public String description;

  @Column(length = 50)
  public String family;

  @Column(nullable = false)
  public Boolean ripen = false;

  @ManyToOne //(fetch = FetchType.LAZY)
  @JoinColumn(name = "tree_name", referencedColumnName = "name")
  @JsonBackReference
  private Tree owner;

树库：

  @ReactiveTransactional
  public Uni<Tree> create(Tree tree) {
    return sf.withTransaction((s, t) -> {s.persist(tree); return s.flush();})
      .replaceWith(sf.withTransaction((s, t) -> s.find(Tree.class, tree.name)));
  }

create 方法不会在数据库中保留任何树，因此所有对 session.find(...) 的调用都返回 null。在将 Tree 关系添加到水果之前，使用此方法在水果存储库中一切正常

  public Uni<Fruit> create(Fruit fruit) {
    return sf.withTransaction((s, t) -> s.persist(fruit))
      .replaceWith(sf.withTransaction((s, t) -> s.find(Fruit.class, fruit.name)));
  }

任何建议表示赞赏。
