form Book,

不好意思
没用过Hibernate愚昧了
看来Query是HQL，应该select类
汗~~~

[rosifox]

猜测你的查询语句是
String hql = "from Book b"，
那么可以选择的修改方式有两种：
1.查询语句改为
String hql = "from " + Book.class.getName() + " b"
2.修改Book.hbm.xml配置为
<hibernate-mapping package="com.yourcompany">
<class name="Book" table="book" schema="dbo" catalog="Test">
<id name="id" type="string">
<column name="id" length="36" />
<generator class="uuid.hex"/>
</id>
<property name="bookName" type="string">
<column name="book_name" length="110" />
</property>
</class>
</hibernate-mapping>

两种取一种就可以，一起应用也没问题

form book 错
form Book
