应用场景：
A表有2两个字段，A1，A2，
映射后的实体类是也只有这两个属性，
现在我有个SQL语句
select A1,A2,(select count(*) from B where b.a1=a.a1) A3
FROM A;

为了得到计算列，我在实体类里添加属性A3，不加@column，，

通过
Sql sql = Sqls.create(sbsql.toString());
sql.setCallback(Sqls.callback.entities());
sql.setEntity(dao.getEntity(A.class));
dao.execute(sql);
List ls=sql.getList(A.class);
无法取到A3的值，
如果声明了@column，则可以取到。

A1 A2 这两属性是否用了@column注解？

如在 POJO 中用了@column注解，那么没有该注解的属性会被忽略掉，详细请看 nutz 的手册

这种情况，你可以为你的A3 声明 @Readonly 属性

我的意思 可以增加一种新的解析方式，用于传入任意bean来获取值，而不需要声明任意属性，这对于自定义查询而不需要写自定义回调函数有很积极的意义。

参照 #456 这个pull request 来改代码自己实现吧。。。
