如何在hibernate中定义瞬态属性？

public class User {
    private int id;
    private String name;
    private transient String tempValue;
    // getters and setters
}

public class User {
    private int id;
    private String name;
    @Transient
    private String tempValue;
    // getters and setters
}

   <class name="com.example.User" table="users">
        <id name="id" column="id">
           <generator class="increment"/>
        </id>
       <property name="name" column="name"/>
       <property name="tempValue" type="string" insert="false" update="false"/>
    </class>
</hibernate-mapping>
