上述错误描述中，关键信息是：

Caused by: org.hibernate.MappingException: Association references unmapped class: com.gifer.model.ReplyMessage

因为我项目中还没有生成这个类：com.gifer.model.ReplyMessage

这是hibernate生成pojo类的时候，自动根据表的主外键关系，自动生成的。而我把类中跟这个有关的信息删除了。

但LoginUser.hbm.xml配置文件中，还有下面这段信息存在

<set name="replyMessages" inverse="true">
            <key>
                <column name="REPLY_USER" length="50" />
            </key>
            <one-to-many class="com.gifer.model.ReplyMessage" />
        </set>
        <set name="sayMessages" inverse="true">
            <key>
                <column name="SAY_USER" length="50" not-null="true" />
            </key>
            <one-to-many class="com.gifer.model.SayMessage" />
        </set>

但对应的set方法被我删除了，所以出现这个错误。
