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

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。

spring-core.xml

spring-back.xml

BaseMybatisDAO

/**
 * 通用DAO的Mybatis实现

 * @author leizhimin 11-12-12 下午10:42

public abstract class BaseMybatisDAO extends SqlSessionDaoSupport implements GenericDAO {
    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。
    @Override
    public void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory) {
        super.setSqlSessionFactory(sqlSessionFactory);
    }
    @Override
    public 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。
