在Hibernate  Annotation  Spring 整合的時候出現的：
解決方法：
<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
 
   <!-- results in a setDriverClassName(String) call -->
   <property name="driverClassName" value="net.sourceforge.jtds.jdbc.Driver"/>
   <property name="url" value="jdbc:jtds:sqlserver://localhost:1433;DatabaseName=db_ajax"/>
   <property name="username" value="123"/>
   <property name="password" value="123"/>
 </bean> 
 
 <bean id="factory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean

">
  <property name="dataSource" ref="myDataSource"></property>
  <property name="hibernateProperties">
   <props>
    <prop key="hibernate.dialect">
     org.hibernate.dialect.SQLServerDialect
    </prop>
   </props>
  </property>
  <property name="annotatedClasses">
   <list>
    <value>com.yin.hibernate.GuestBook</value>
   </list>
  </property>
 </bean>

在 Hibernate distribution Spring整合時
<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
 
   <!-- results in a setDriverClassName(String) call -->
   <property name="driverClassName" value="net.sourceforge.jtds.jdbc.Driver"/>
   <property name="url" value="jdbc:jtds:sqlserver://localhost:1433;DatabaseName=db_ajax"/>
   <property name="username" value="123"/>
   <property name="password" value="123"/>
 </bean> 
 
 <bean id="factory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean

">
  <property name="dataSource" ref="myDataSource"></property>
  <property name="hibernateProperties">
   <props>
    <prop key="hibernate.dialect">
     org.hibernate.dialect.SQLServerDialect
    </prop>
   </props>
  </property>
  <property name="mappingResources">
   <list>
    <value>com/yin/hibernate/GuestBook.hbm.xml</value>
   </list>
  </property>
 </bean>

上面只需要注意紅色的部分就行了
