Struts2中使用ModelDriven Set<OrderDetail> 无法赋值
Order类中包含Set<OrderDetail>
@OneToMany(targetEntity=OrderDetail.class,mappedBy="order",fetch=FetchType.EAGER)
// @Element(value = OrderDetail.class)
// @Key(value = Integer.class)
// @KeyProperty(value = "id")
// @CreateIfNull(value = true)
private Set<OrderDetail> orderDetails=new HashSet<OrderDetail>();
Action中
public class OrderAction implements ModelDriven<Order>{
private static final long serialVersionUID = 1L;
private OrderService orderService;
public void setOrderService(OrderService orderService) {
this.orderService = orderService;
}
@ShowValue(value="产生订单",page="付款页面")
public String makeOrder(){
System.out.println(model);
System.out.println(model.getOrderDetails());
return "makeOrder";
}JSP中写OrderDetail
<form action="order_front_makeOrder" method="post">
orderDetails[0].personName:<input type="text" name="orderDetails[0].personName" value="大黄"/>
orderDetails[0].personType:<input type="text" name="orderDetails[0].personType" value="ELDER"/>
orderDetails[0].personNo:<input type="text" name="orderDetails[0].personNo" value="13499756425"/>
orderDetails[0].personNoType:<input type="text" name="orderDetails[0].personNoType" value="IDCARD"/>
orderDetails[1].personName:<input type="text" name="orderDetails[1].personName" value="小耿"/>
orderDetails[1].personType:<input type="text" name="orderDetails[1].personType" value="ELDER"/>
orderDetails[1].personNo:<input type="text" name="orderDetails[1].personNo" value="13499436425"/>
orderDetails[1].personNoType:<input type="text" name="orderDetails[1].personNoType" value="IDCARD"/>
orderDetails[2].personName:<input type="text" name="orderDetails[2].personName" value="小陈"/>
orderDetails[2].personType:<input type="text" name="orderDetails[2].personType" value="ELDER"/>
orderDetails[2].personNo:<input type="text" name="orderDetails[2].personNo" value="13493244326425"/>
orderDetails[2].personNoType:<input type="text" name="orderDetails[2].personNoType" value="IDCARD"/>
<input type="submit"/>错误：应该算异常，在Action中取不到OrderDetail[].

[]其他简单的，比如order.number是可以取到值的。唯独Set<OrderDetail>取不到值。
求助！万分感谢！
