mybatis两个DAO是不可能的？

Question

同时使用两个DAO是不可能的？

以下是我使用的代码：

public class MyBatisconfig {
    private static SqlSessionFactory sqlSessionFactory;

    public static SqlSessionFactory getSqlSessionFactory() {
    if (sqlSessionFactory == null) {
        String resource = "mybatis-config.xml";
        Reader reader; 
        try {
            reader = Resources.getResourceAsReader(resource);
            sqlSessionFactory =
                    new SqlSessionFactoryBuilder().build(reader);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    return sqlSessionFactory;
}

}

AdminDAO.class

private SqlSessionFactory factory = MyBatisconfig.getSqlSessionFactory();

UserDAO.class

private SqlSessionFactory factory = MyBatisconfig.getSqlSessionFactory();

的MyBatis-config.xml中

    

<typeAliases>
    <typeAlias type="human.vo.User" alias="user" />
    <typeAlias type="human.vo.Admin" alias="admin" />

</typeAliases>

<environments default="development"> 
    <environment id="development"> 
        <transactionManager type="JDBC" />
        <dataSource type="POOLED">
            <property name="driver" value="${driver}" />
            <property name="url" value="${url}" />
            <property name="username" value="${username}" />
            <property name="password" value="${password}" />
        </dataSource>
    </environment>
</environments>
<mappers>
    <mapper resource="mappers/userMapper.xml" />
    <mapper resource="mappers/adminMapper.xml" />
</mappers>

使用getSqlSessionFactory会抛出错误。
