错误记录（五）Error creating bean with name 'sessionFactory' defined in file

在hibernate和spring整合时，出现错误如下：

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in file [G:\workspace\s_hibernate\src\applicationContext.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Error applying BeanValidation relational constraints

经过一番查找，终于解决了这个错误，原因出现在applicationContext.xml配置中：

<beanid="sessionFactory"class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<propertyname="dataSource"ref="dataSource" />
<propertyname="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>
<propertyname="packagesToScan"value="com.bolo.examples.entity.*"/>
</bean>

 <prop key="javax.persistence.validation.mode">none</prop>   
加入粗体加下划线部分就没有问题了
真是不同的版本差异比较大啊

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
<propkey="javax.persistence.validation.mode">none</prop>
是auto而不是none!
 
------------------------------------------------------------------------------------------------------------------------------------------
 
javax.persistence.validation.mode默认情况下是auto的，就是说如果不设置的话它是会自动去你的classpath下面找一个bean-validation**包，但是找不到，所以beanvalitionFactory错误。
由于javax.persistence.validation.mode的属性值默认是auto，所以会出错。
 
在hibernate.cfg.xml里将javax.persistence.validation.mode设置为none，就可以避免出错了。
 
  <!-- Disable the BeanValidation-->
 <propertyname="javax.persistence.validation.mode">none</property>
------------------------------------------------------------------------------------------------------------------------------------------
 
 
所以，Hibernate3.6以上版本在用junit测试时会提示错误：
 
Unable to get thedefault Bean Validationfactory
 
 
 
在hibernate.cfg.xml里增加一属性解决：   
 
 
 
<propertyname="javax.persistence.validation.mode">none</property>
