搞了 2天了，还是不知道什么原因，请 大侠 支援下！

我自己找出来了，原因是：
<property name="bookAuthor" type="java.lang.String" node="@bookAuthor">
<column name="bookAuthor" length="100" />
</property>
数据库中的字段名是：book_Author,映射时出错了
改成：
<property name="bookAuthor" type="java.lang.String" node="@book_Author">
<column name="book_Author" length="100" />
</property>
