SequenceStyleGenerator，如何使用前缀而非后缀

<class name="com.example.EntityClass">
    <id name="id" column="id" type="long">
        <generator class="org.hibernate.id.enhanced.SequenceStyleGenerator">
            <param name="sequence_name">sequence_name</param>
            <param name="optimizer">hilo</param>
            <param name="increment_size">100</param>
            <param name="prefix">PREFIX_</param> <!-- 设置前缀 -->
        </generator>
    </id>
</class>
