本文记录了在Spring4.0.5与Hibernate4.3.1集成时遇到的sessionFactory配置问题及解决办法。主要问题是由于使用连接池导致Hibernate无法正确获取数据库元数据，通过设置hibernate.temp.use_jdbc_metadata_defaults为false解决了该问题。

spring配置出错at org.hibernate.engine.jdbc.internal.JdbcServicesImpl.configure(JdbcServicesImpl.java:244

 

1.SSM集成:

spring 4.0.5

hibernate 4.3.1;

sessionFactory 注入datasource

 

  1.  
    <bean id="sf" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
  2.  
    <property name="dataSource" ref="myDataSource" />
  3.  
    <property name="packagesToScan">
  4.  
    <list>
  5.  
    <value>xx.xx.model</value>
  6.  
    </list>
  7.  
    </property>
  8.  
    <property name="hibernateProperties">
  9.  
    <props>
  10.  
    <prop key="hibernate.dialect">

3.查了半天也没发现问题在哪里,

后来看到了一位博友博文: http://blog.youkuaiyun.com/luxiaoshuai/article/details/40540929

原来是使用连接池注入的数据源 需要添加如下一条属性:

 

<prop key="hibernate.temp.use_jdbc_metadata_defaults">false</prop>

 

 

配置如下:

 

  1.  
    <bean id="sf"
  2.  
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
  3.  
    <property name="dataSource" ref="myDataSource" />
  4.  
    <property name="packagesToScan">
  5.  
    <list>
  6.  
    <value>xx.xx.model</value>
  7.  
    </list>
  8.  
    </property>
  9.  
    <property name="hibernateProperties">
  10.  
    <props>
  11.  
    <prop key="hibernate.dialect">
  12.  
    org.hibernate.dialect.Oracle9Dialect
  13.  
    </prop>
  14.  
    <prop key="hibernate.show_sql">true</prop>
  15.  
    <!-- 重要: 使用连接池设置false -->
  16.  
    <prop key="hibernate.temp.use_jdbc_metadata_defaults">false</prop>
  17.  
    </props>
  18.  
    </property>
  19.  
    </bean>



 

添加上以后,问题立马解决! 

以后还是要多看源码啊.
