Spring3 整合MyBatis3 配置多数据源 动态选择SqlSessionFactory（转）

1. Spring整合MyBatis切换SqlSessionFactory有两种方法，第一、 继承SqlSessionDaoSupport，重写获取SqlSessionFactory的方法。第二、继承SqlSessionTemplate 重写getSqlSessionFactory、getConfiguration和SqlSessionInterceptor这个拦截器。其中最为关键还是继承SqlSessionTemplate 并重写里面的方法。

我们一般使用第二种方法，第二种方法有2 种配置：

单个sqlSessionFactory情况：需要在程序中（action 里面动态指定使用那个数据库连接池）

spring-mybatis.xml配置如下：
