Hibernate 报错 Dialect does not support identity key generation

设置数据库方言不要写错

1.SQLSERVER

<property name="hibernateProperties">
            <props>
                <!-- 设置Hibernate的数据库方言为SQLSERVER -->
                <prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop>
                <!-- 设置Hibernate是否在控制台输出SQL语句，开发调试阶段通常设为true -->
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.format_sql">true</prop>
            </props>
        </property>

2.ORACLE

<!-- 设置Hibernate的相关属性 -->
        <property name="hibernateProperties">
            <props>
                <!-- 设置Hibernate的数据库方言为Oracle9Dialect -->
                <prop key="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect</prop>
                <!-- 设置Hibernate是否在控制台输出SQL语句，开发调试阶段通常设为true -->
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.format_sql">true</prop>
            </props>
        </property>
