springframwork 不支持 hibernate 4 多租户
最近想升级hibernate 到4，因为需要用到它的多租户特性。可是在跑用例的时候发现spring不兼容，用的是3.1.3.release版本。

1 楼 ksedward 2012-11-07 原因好像是：
org.springframework.orm.hibernate4.SessionFactoryUtils类的方法：
public static DataSource getDataSource(SessionFactory sessionFactory) {
if (sessionFactory instanceof SessionFactoryImplementor) {
ConnectionProvider cp = ((SessionFactoryImplementor) sessionFactory).getConnectionProvider();
return cp.unwrap(DataSource.class);
}
return null;
}
获取datasource的时候使用ConnectionProvider 而不是 MultiTenantConnectionProvider
我的异常网推荐解决方案：org.springframework.beans.factory.BeanCreationException:,http://www.myexception.cn/j2ee/10759.html
