我知道这是一个常见问题，但没有一个可用的解决方案适合我。 下面是我的booltstraps.xml：

如果我明确地将<prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop>添加到hibernate属性，它就会开始工作。
在线提供的最常见答案是连接数据库时存在一些问题。所以我尝试编写一段单独的代码来访问具有相同细节的数据库，并且它有效。 不知道问题是什么。

在XML Spring配置中，您必须更新：
<bean class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" id="sessionFactory" lazy-init="true">
<property name="dataSource" ref="dataSource"/>
<property name="hibernateProperties">
<props>
<prop key="hibernate.cache.use_second_level_cache">false</prop>
<prop key="hibernate.cache.use_query_cache">false</prop>
<prop key="hibernate.show_sql">false</prop>
<!-- HERE THE DIALECT CONFIGURATION -->
</props>
</property>
</bean>
从Hibernate documentation起，您必须提供如下方言：
<prop key="hibernate.dialect">org.hibernate.dialect.SQLServer2008Dialect</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop>
答案 1 :(得分：1)
如果您指定数据库名称，则无需设置方言。为此，您可以将JpaVendorAdaptor用作org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean的属性 或HibernatePersistenceProvider（适用于低于5的休眠版本） 在这种情况下，如果是Microsoft sql服务器
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="generateDdl" value="true" />
<property name="database" value="SQL_SERVER" />
</bean>
</property>
