list查询棚舍面积的时候,所有棚舍面积的value都是一样的

　　解决办法

将pickingid在查list之前set到对象中,通过id来匹配查询

具体代码:

 FarmHouse farmHouse=new FarmHouse();
        farmHouse.setPickingid(po.getId());
        List<FarmHouse> fhList=farmHouseService.selectList(farmHouse);
        if(fhList.size()>0){

        mv.addObject("vo1",fhList.get(0));}
