Spring3.2.8+Mybatis3.2.6 多数据源基于BaseDAO的配置

配置数据源为：

MySQL5.5.6

H2Database 1.3.75

这个配置起来比较麻烦，本文这种方法有点麻烦，就是dao不能再用注解了，但是程序简单。还有别的方法，后续放出。

BaseMybatisDAO

/*** 通用DAO的Mybatis实现** @author leizhimin 11-12-12 下午10:42*/
public abstract class BaseMybatisDAO<E, PK extends Serializable> extends SqlSessionDaoSupport implements GenericDAO<E, PK> {protected String sqlmapNamespace;   //ibatis sql map的命名空间，即使用实体类的简单名称protected Class entityType;         //运行时的实体类型，也对应为SQL的命名空间。@Overridepublic void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory) {super.setSqlSessionFactory(sqlSessionFactory);}@Overridepublic void setSqlSessionTemplate(SqlSessionTemplate sqlSessionTemplate) {super.setSqlSessionTemplate(sqlSessionTemplate);}

BaseMybatisDAO省略具体实现代码，仅保留需要注入的两个setter方法。

测试下：
