JAXB不封送循环引用

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，但似乎没有，因为我得到了这个错误：

Jul 30, 2018 4:28:08 PM org.eclipse.yasson.internal.Marshaller marshall
SEVERE: Generating incomplete JSON

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....
}

如果从各自中删除Interview和Stock引用，则可以进行封送处理。

Answer 2

我不确定为什么OP不共享jars，但至少这条错误消息

org.eclipse.yasson.internal.Marshaller marshall
SEVERE: Generating incomplete JSON

为我解决了以下依赖关系。
