Question

我有两个实体Folder和Init具有OneToMany关系，当我添加一个文件夹时，我想设置init并将其保存在DB中..但是当我发送表单时，我在我的sclipse控制台中得到了这个错误（JAVA））

Folder.java

@Id
@Column(name = "ID")
private Long id;
@Column(name = "NOFOLDER")
private String noFolder;
/** Getter + setter **/

Init.java

    @Id
    @Column(name = "ID")
    private Long id;
    @Column(name = "NAME")
    private String name;
    @Column(name = "SURNAME")
    @OneToMany(fetch=FetchType.EAGER, cascade={CascadeType.PERSIST})
    @JoinColumn(name = "INIT", referencedColumnName = "ID")
    private List<Folders> folders = new ArrayList<Folders>();
/*  Getter  Setter */

在我的角度中，我为发送表单执行此操作：的 folder.html

<label>No Folder :</label>
<div class="col-sm-4">
    <input [(ngModel)]="noFolder" name="noFolder" type="text">
</div>
<div class="col-sm-4">
    <input [(ngModel)]="initiator.name" name="name" type="text">
</div>
<div class="col-sm-4">
    <input [(ngModel)]="initiator.surname" name="surname" type="text">
</div>

    <button type="button" (click)="saveFolder()">SUBMIT</button>

folder.ts

folder;
initiator;
saveFolder() {
   this.folder.noFolder =  noFolder;
   this.folder.initiator = this.initiator;

     this.folderService.saveFold(this.folder).subscribe(
      data => {
       },
      error => {
     });
}

无法反序列化business.enities.folders.Init实例的START_ARRAY标记
