Question

我以前使用过JAXB从循环数据结构生成json，我想这次我做了同样的事情，但显然没有，因为我遇到了这个错误：

这是来源：

@XmlAccessorType(XmlAccessType.FIELD)
@Entity
@Table(name="INTERVIEW")
public class Interview {
    @Id
    @GeneratedValue
    @Column (name = "ID")
    private int id;
    @Column (name="DATE")
    private Date date_;
    @Column (name="TITLE")
    private String title;
    @Column (name="CEO")
    private String ceo;
    @OneToMany (mappedBy="interview", cascade = CascadeType.ALL, orphanRemoval = true)
    private List<QA> QAs;
    @OneToOne
    @JoinColumn(name="STOCK_ID")
    @XmlTransient
    private Stock stock;

    ....GETTERS and SETTERS...
}


@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
@Entity
@Table(name="STOCK")
public class Stock {
    @Id
    @GeneratedValue
    @Column (name = "ID")
    private int id;
    @Column (name="TITLE")
    @OneToOne(cascade = CascadeType.ALL, orphanRemoval = true, mappedBy = "stock")
    private Interview interview;

    ....GETTERS AND SETTERS....
}

如果我从各自的网站上删除采访和股票参考，我可以进行封送。

Answer 1

已解决。一些工作需要的运动衫

Answer 2

不确定为什么OP不会共享jar，但至少会显示此错误消息

raw_data

对于我来说，具有以下依赖性已得到解决。

(timestamp)

JAXB不要封送循环引用
