无法将对象从操作类传递到Jsp

问题描述 投票：1回答：1

我将struts2与约定的gingin结合使用angularjs。我有一个动作类和jsp，如下所示：

IndexAction.java

package sm.hris.struts2.base.modules.order;

import java.util.ArrayList;
import java.util.Date;

import org.apache.struts2.convention.annotation.InterceptorRef;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.apache.struts2.convention.annotation.Result;
import org.apache.struts2.convention.annotation.Results;

import sm.hris.struts2.base.SmBaseAction;
import sm.hris.struts2.base.db.Order;
import sm.hris.struts2.base.db.OrderDAO;
import sm.hris.struts2.base.modules.order.IndexAddAction;


@Results({
    @Result(name="add", location="/base/modules/order/index-add", type="redirect"),
    })
@ParentPackage(value = "hris")

public class IndexAction extends SmBaseAction {
    private static final long serialVersionUID = 7353477345330099548L;
    private Order order = new Order();
    private OrderDAO orderDAO = new OrderDAO();
    private ArrayList<Order> orders;
    private String idOrder = new String();
    private String searchKey = new String();
    private ArrayList<String> formArg = new ArrayList<String>();
    private ArrayList<String> idOrders = new ArrayList<String>();
    private String proc = new String();
    private String res = new String();
    private IndexAddAction indexAddAction = new IndexAddAction();

    public String execute() throws Exception{
        //super.listMenu();
        if(proc.equals("Add")){
            order.setOrderDate(new Date());
            orderDAO.setOrder(order);
            String strIdOrderCounter = orderDAO.orderAdd();
            ArrayList<String> argArray = new ArrayList<String>();
            argArray.add(0,strIdOrderCounter);
            orderDAO.setArgArray(argArray);
            orders = orderDAO.searchOrderByIdOrder();
            order = orders.get(0);
            res= "add";
        }
        if(proc.equals("Delete")){
            res = orderDelete();
        }
        if(!(proc.equals("Add")||proc.equals("Delete"))){
            if (!searchKey.equals("")) {
                formArg.add("%"+searchKey+"%");
                orderDAO.setArgArray(formArg);
                orders = orderDAO.searchOrderByAnyLike();
                res="success";
            } 
            else {
                orders = orderDAO.searchOrder();
                res="success";
            } 
        }
        return res;
    }

    public String orderDelete() throws Exception {
        orderDAO.setArgArray(idOrders);
        orderDAO.orderDelete(); 
        return "success";
    }

    public String orderAdd() throws Exception {
        return "add";
    }


    //---- Getter Setter ----// 

    public String getIdOrder(){
        return idOrder;
    }

    public void setIdOrder(String idOrder){
        this.idOrder=idOrder;
    }

    public String getSearchKey(){
        return searchKey;
    }

    public void setSearchKey(String searchKey){
        this.searchKey=searchKey;
    }

    public ArrayList<String> getIdOrders(){
            return idOrders;
        }

    public void setIdOrders(ArrayList<String> idOrders){
            this.idOrders=idOrders;
        }

    public ArrayList<Order> getOrders(){
        return orders;
    }

    public void setOrders(ArrayList<Order> orders){
        this.orders = orders;
    }

    public Order getOrder(){
        return order;
    }

    public void setOrder (Order order){
        this.order = order;
    }

    public void setProc(String proc) {
        this.proc = proc;
    }

我的问题是：为什么，似乎订单没有从动作类传递给jsp。从order.idOrder可以看出我没有尝试显示在jsp中。有人可以帮忙吗？非常感谢

如何在Web应用程序中结合Struts2和AngularJS取决于控制器的配置。通过约定插件创建的配置Struts2可以用于Struts MVC框架生成的前端，也可以用于AngularJS MVW框架创建的前端。

请参见MVVM architectural pattern with AngularJS的示例和说明。

在第一种情况下，您使用Java并在服务器上使用Java，并结合使用诸如jsp，freemarker，speed等的模板语言。要从视图访问模型对象，可以使用诸如EL，OGNL之类的表达式语言等

在第二种情况下，您使用模型并结合JavaScript和AngularJS在client上进行查看。在这种情况下，为了从服务器获取数据，应用程序将使用http客户端和支持的服务，这些服务以JSON格式返回数据。如果您在后端使用struts 2，则应创建AngularJS应用程序可以使用的相应API。

这是example如何使用AngularJS的API。在这种情况下，通过rest插件创建的struts 2后端。可以在AngularJS应用程序的后端上使用。

在this答案中，您可以找到在为angularJS应用程序创建struts 2后端时如何将约定和rest插件结合在一起的示例
