java - JAXB / Jackson 不允许为 HashSet 项目选择名称

Question

在这里，我们在父实体中将列表定义为一个集合：

@XmlElement(name = "picks")
@JacksonXmlElementWrapper(localName = "picks")
@OneToMany(fetch = FetchType.EAGER, mappedBy = "tour", cascade=CascadeType.ALL)
private Set<Pick> picks = new HashSet<Pick>();

并且子实体本身具有定义的名称：

@Entity
@Table(name = "picks")
@XmlAccessorType(XmlAccessType.FIELD)
@JacksonXmlRootElement(localName = "pick")
@XmlRootElement(name = "pick")
public class Pick {

然而，XML 包含根元素和子元素的“选择”！

<picks><picks><losPickId>2</losPickId><pickID>167</pickID>

看起来注释不起作用。有任何想法吗？

尝试注释picks：

@XmlElementWrapper(name = "picks")
@XmlElement(name = "pick")
