我想通过使用 hj:generated-value tag 将现有属性标记为生成的标识符来自定义我的 hyperjaxb3 生成的类。在我的 bindings.jxb 文件中，我将 Status 的 id 标记为标识符，但生成的实体未使用 @GeneratedValue 进行注释。因此，Status 表的 id 字段在数据库中被标记为 pkey 但不是自动递增的。

XML 模式定义：

<complexType name="Status">
<sequence>
<element name="id" type="long">
</element>
<element name="title" type="string"></element>
<element name="description" type="cm:LongText"></element>
</sequence>
</complexType>

bindings.xjb 中的 Hyperjaxb3 自定义： 

<jaxb:bindings node="xs:complexType[@name='Status']">
            <jaxb:bindings node=".//xs:element[@name='id']">
                <hj:id> <hj:generated-value strategy="AUTO"/> 
                    </hj:id>
            </jaxb:bindings>
        </jaxb:bindings>

结果类：

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "Status", propOrder = {
    "id",
    "title",
    "description"
})
@XmlRootElement(name = "status")
@Entity(name = "Status")
@Table(name = "STATUS")
@Inheritance(strategy = InheritanceType.JOINED)
public class Status
    implements Equals, HashCode
{

    protected long id;
    @XmlElement(required = true)
    protected String title;
    @XmlElement(required = true)
    protected String description;

    /**
     * Gets the value of the id property.
     * 
     */
    @Id
    @Column(name = "ID", scale = 0)
    public long getId() {
        return id;
    }

    /**
     * Sets the value of the id property.
     * 
     */
    public void setId(long value) {
        this.id = value;
    }

    @Transient
    public boolean isSetId() {
        return true;
    }
    ......

在 Postgres 9.2 中使用 hibernate 作为 jpa 提供程序。pom.xml：

改用orm:generated-value：

<jaxb:bindings node=".//xs:element[@name='id']">
   <hj:id> 
     <orm:generated-value strategy="AUTO"/> 
   </hj:id>
</jaxb:bindings>
