我有如下的sql（MySQL）：
select a.code as 'a.code', b.code as 'b.code', c.code  as 'c.code' from a, b, c where a.code=b.code and a.code = c.code;
查询结果如下：
--------------------------------------------
a.code    |    b.code    |    c.code
------------------------------------------
   N001   |    N001      |     N001
   N002   |    N002      |     N002
   N003   |    N003      |     N003
-------------------------------------------
目前有一个pojo：
class Pojo {
private A a;
private B b;
private C c;
// getter/setter
}
class A {private String code;}
class B {private String code;}
class C {private String code;}

如何查询结果为List<Pojo> list;
（mybatis能自动映射）
