我正在向您展示我已经拥有的课程，并且我想使用 jaxb 进行序列化。不幸的是，当我尝试在 Person 内部序列化 positionSet 时，我无法完全获得 Person 对象内部的所有属性
代码：
public class Person {
@Id
@Column(name = "ID")
private Integer id;
@Column(name = "FIRST_NAME")
@NotNullOnlyJsp
private String firstName;
@Column(name = "LAST_NAME")
@NotNullOnlyJsp
private String lastName;
@OneToMany(cascade = { CascadeType.ALL }, fetch = FetchType.LAZY, mappedBy = "person")
@org.hibernate.annotations.OrderBy(clause = "start_date asc")
private Set<Position> positionSet = new LinkedHashSet<Position>();
// getter and setter and other methods..
}
public class Position{
@Id
@Column(name = "ID")
private Integer id;
@Column(name = "FK_PERSON")
@NotNull
private Integer personId;
@Column(name = "FK_POSITION_TYPE")
@NotNull
private Integer positionTypeId;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "FK_POSITION_TYPE", insertable = false, updatable = false)
private Entity positionType;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "FK_PERSON", insertable = false, updatable = false)
// I need this annotation to avoid ciclyc graph
@XmlInverseReference(mappedBy="positionSet")
private Person person;
@Column(name = "FK_ORG_UNIT")
@NotNull
private Integer organizationUnitId;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "FK_ORG_UNIT", insertable = false, updatable = false)
// I need this annotation to avoid ciclyc graph
@XmlInverseReference(mappedBy="organizationUnitPositionSet")
private OrganizationUnit organizationUnit;
// getter and setter and other methods..
}
public class OrganizationUnit{
@Id
@Column(name = "ID")
private Integer id;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "FK_ORG_UNIT_TYPE", insertable = false, updatable = false)
private OrganizationUnitType organizationUnitType;
@Column(name = "FK_ORG_UNIT_TYPE")
private Integer organizationUnitTypeId;
@Column(name = "DESCRIPTION", length = 4000)
@NotNull
private String description;
@OneToMany(cascade = { CascadeType.ALL }, fetch = FetchType.LAZY, mappedBy = "organizationUnit")
@org.hibernate.annotations.OrderBy(clause = "start_date asc")
// I need this annotation to avoid ciclyc graph
private Set<Position> organizationUnitPositionSet = new LinkedHashSet<Position>();
// getter and setter and other methods..
}
现在，正如您可以理解的那样，关系是： Person 一对多 Position 多对一 OrganizationUnit Position 有两个属性：“positionType”和“organizationUnit”，它们引用了 OrganizationUnit 当 jaxb 序列化时，我只能看到 positionType 元素和关于 organizationUnit 元素的任何内容内位置。我试图检查 Position 是否包含值，并且发现数据在对象内部可用。Position 类中positionType 和organizationUnit 属性之间的区别在于@XmlInverseReference 注释，我需要OrganizationUnit 类映射的organizationUnit 属性，而我不需要positionType 的此注释。
我该如何解决这个问题？为什么注释不允许我访问 Position 中的 organizationUnit？
我希望有人能帮助我。为了向您展示它序列化但不正确，我将向您展示 xml 输出文件：我看不到 organizationUnit 属性
<person>
// other property
<position-set>
<position>
<id>174215</id>
<discriminator>support</discriminator>
<endDate>2005-06-30T00:00:00</endDate>
<organizationUnitId>1234</organizationUnitId>
<positionType>

</organization-unit-type>
</positionType>
<startDate>2005-02-01T00:00:00</startDate>
</position>
</position-set>
