Question

我正在向你展示我已经拥有的课程，我想用jaxb序列化。不幸的是，当我尝试在Person中序列化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..    
    }

现在您可以理解这些关系是：一对多的人将多个组织定位于一个组织单位 Position有两个属性：“positionType”和“organizationUnit”，它们引用OrganizationUnit 当jaxb序列化时，我只能看到positionType元素和关于Position中的organizationUnit元素的任何内容。我试图检查位置是否包含值，并且我发现数据在对象内部可用。位置类中的positionType和organizationUnit属性之间的区别是由OrganizationUnit类映射的organizationUnit属性所需的@XmlInverseReference批注，而我不需要这个positionType批注。

我该如何解决这个问题？为什么注释不允许我访问位置内的organizationUnit？

我希望有人可以帮助我。用于向您显示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>
                    <id>2733</id>
                    <displayValue>BLABLA</displayValue>
                        <organization-unit-type>
                            <id>101</id>
                            <description>supportRole</description>
                        </organization-unit-type>
                </positionType>
            <startDate>2005-02-01T00:00:00</startDate>
        </position>
    </position-set>

我只是通过删除Position类中的organizationUnit属性上的注释@XmlInverseReference来解决，我为OrganizationUnit类中的属性positionSet指定了xml-transient
