我想使用 ModelDriven 将收据列表添加到数据库中。这是行动
public class AddReceipAction extends ActionSupport implements ModelDriven<List<Receiptitem>>{
private List<Receiptitem> receiptItemList;
public List<Receiptitem> getReceiptItemList() {
return receiptItemList;
}
/**
* @param receiptItemList the receiptItemList to set
*/
public void setReceiptItemList(List<Receiptitem> receiptItemList) {
this.receiptItemList = receiptItemList;
}
@Override
public List<Receiptitem> getModel() {
return receiptItemList; //To change body of generated methods, choose Tools | Templates.
}
@Action(value="addreceipt",
results = {
@Result(name="success", location="/w_receipting.jsp")
})
public String Addreceipt()
{
List<Receiptitem> temp = new ArrayList<Receiptitem>();
for (Receiptitem item : receiptItemList)
{
if(item != null)
temp.add(item);
}
ReceipDAO receipDAO = new ReceipDAO();
receipDAO.add(temp);
return SUCCESS;
}
}
这是 jsp 页面：文本字段的名称是 Receipitem 对象的属性

但它不起作用，receiptItemList 中的所有 Receiptitem 都为空。
