检查思路：
1、检查数据库是否开启；--已开启
2、检查表映射文件与实体类是否有问题。--没问题
3、检查配置文件applicationContext.xml
参考http://www.cnblogs.com/aipeli/articles/2537357.html
解决办法：
在使用Spring和Hibernate进行结合的时候出现了这个问题！
<prop key="javax.persistence.validation.mode">none</prop>
在配置文件中添加这个！
<property name="hibernateProperties">
<props>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="javax.persistence.validation.mode">none</prop>
</props>
</property>
其实这个问题是我们自己造成的！为什么这么说？因为我们在配置Spring和Hibernate进行结合的时候版本出现了问题。
<persistence ...>
<persistence-unit ...>
...
<properties>
<property name="javax.persistence.validation.mode"
value="callback, ddl"/>
</properties>
</persistence-unit>
</persistence>
这是hibernate官方文档的一段话意思就是在hibernate.cfg.xml或者是persistence.xml文件下面需要配置
javax.persistence.validation.mode属性!
特别的！在Hibernate中默认的 <prop key="javax.persistence.validation.mode">none</prop>
是auto而不是none!
