spring官方文档总提示要进行SpringJunit测试必须先配置两个信息：
1、使用Spring IOC功能配置
2、配置正确的JDBC或ORM框架连接数据库
下面进行spring3和hibernate4测试平台基础配置说明：

1、注意如果你使用的是hibernate3则需要将org.springframework.orm.hibernate4.HibernateTransactionManage改为org.springframework.orm.hibernate3.HibernateTransactionManage
2、此处使用出c3p0连接池，可以根据实际情况更改
3、hibernate配置文件为：
<?xml version=‘1.0‘ encoding=‘UTF-8‘?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
</session-factory>
</hibernate-configuration>
需要制定数据库方言
