java 代码
代码如下:
publicclassGoods{
....
privateDateModelgoodsList;
...
publicDataModelgetGoodsList(){
if(goodsList==null){
goodsList=newDataModel();
}
goodsList.setWrappedData(getRealGoodsList());//这里通过Service层或者Dao层访问到数据库
retrungoodsList;
}
publicStringselect(){
GoodsselectedGoods=(Goods)goodsList.getRowData();
setSelectedGoods(selectedGoods);
return"success";
}
