public String doSearch(){
Map<String,Object> params = new HashMap();
params.put("page", page);
Object[] o =service.findAll(params);
page = new Page();
//Object[0]当前页的数据列表List,Object[1]总页数 ,Object[2]总记录数.
page.setList((List<Object>)o[0]);
page.setTotalCount(Integer.parseInt(String.valueOf(o[2])));
//到这的时候 page 对象当中就已经有值了 包括page下的list对象 ，和page下的totalcount对象
//list对像里放的 应该是查询出来的数据集合（内容） totalcount对象是总共的记录数（数量）
System.out.println("page中的List: "+page.getList().size()+"page中的totalpagecount: "+page.getTotalPageCount()+"page中的totalcount: "+page.getTotalCount());
return "success";
}
public static void main(String args[]){
HouseAction House = new HouseAction();
House.doSearch();
}
}这个运行结果是
page中的List: 4page中的totalpagecount: 1page中的totalcount: 4
那也就是说page里面有信息的
