思路：
1、商家：
? ? ? ? 查看订单
? ? ? ? 发货-->“订单状态”：1=未发货、2=已发货、3=已签收、4=已撤单 （默认值1）
? ? ? ? 订单项的查看
实现思路：
分析功能： 订单表的查询 ? 、 ?将订单表的订单状态由1改成2 ? 、通过订单的id到订单项表查询出对应的订单项
2、买家：
功能： ?查看订单、 ?撤单、 ? 签收
实现思路：
? ? ? ? 订单表的查询
? ? ? ? 将订单表的订单状态由1改成4
? ? ? ? 将订单表的订单状态由2改成3
3、编码思路：
? 商家：
? ? ?实体类：Order
? ? ? Dao层：
? ? ? ? ? ? ?OrderDao：新增两个方法：①、订单的查询，通过订单号查询 ? ? ? ②、修改订单状态
? ? ? ? ? ? ?OrderItemDao:新增一个方法：①、通过外键订单id查询订单项表
? ? 买家： 实体类： ?OrderItem
? ? ? ? ? ? ? Dao层：
? ? ? ? ? ? ? ? ? OrderDao：新增两个方法：①、订单的查询，通过订单号查询 ②、修改订单状态
一、订单管理代码

success: function (data) {

2、订单表OrderDao方法
/**
* 按照订单时间倒叙查询
* @param order
* @param pageBean
* @return
* @throws Exception
*/
public List<Order> list(Order order, PageBean pageBean) throws Exception {
// String sql="select * from t_easyui_order order by orderTime desc";
String sql = "select * from t_easyui_order where 1=1 ";
long id = order.getId();
int orderState = order.getOrderState();
if (id != 0) {//意味着从前台传了订单号
sql += " and id=" + id;//根据订单id进行查询
}
//用来根据订单状态分类查询
if (orderState != 0) {
sql += " and orderState=" + orderState;//根据订单的状态进行查询
}
//使用sql的时候注意打空格，防止出现sql语句拼接错误
sql += " order by orderTime desc";
return super.executeQuery(sql, Order.class, pageBean);
}
3、子控制器OrderAction
package com.zking.web;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.zking.dao.OrderDao;
import com.zking.entity.Order;
import com.zking.framework.ActionSupport;
import com.zking.framework.ModelDriver;
import com.zking.util.BaseDao;
import com.zking.util.PageBean;
import com.zking.util.R;
import com.zking.util.ResponseUtil;
public class OrderAction extends ActionSupport implements ModelDriver<Order>{
private Order order=new Order();
private OrderDao orderDao=new OrderDao();
public Order getModel() {
return order;
}
public void list(HttpServletRequest req, HttpServletResponse resp) {
PageBean pageBean=new PageBean();
pageBean.setRequest(req);
try {
List<Order> list = orderDao.list(order, pageBean);
ResponseUtil.writeJson(resp, new R().data("total", pageBean.getTotal()).data("rows", list));
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* 关于发货 撤单 签收 公用的方法
* @param req
* @param resp
*/
public void cancelAndReceive(HttpServletRequest req, HttpServletResponse resp) {
//order就已经包含了将要修改的状态以及对应的订单id
try {
orderDao.editState(order);
ResponseUtil.writeJson(resp, 1);
} catch (Exception e) {
e.printStackTrace();
try {
ResponseUtil.writeJson(resp, 0);
} catch (Exception e1) {
e1.printStackTrace();
}
}
}
}
4、配置MVC.xml
<action type="com.zking.web.OrderAction" path="/order">
</action>
??二、显示订单项
1、订单项前端代码
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>商家订单页面</title>
<link rel="stylesheet" type="text/css"
href="${pageContext.request.contextPath}/static/js/easyui/themes/default/easyui.css">
<link rel="stylesheet" type="text/css" href="${pageContext.request.contextPath}/static/js/easyui/themes/icon.css">
<script src="https://cdn.bootcss.com/jquery/1.12.4/jquery.js"></script>
<script type="text/javascript"
src="${pageContext.request.contextPath}/static/js/easyui/jquery.easyui.min.js"></script>
<script src="${pageContext.request.contextPath}/static/js/main.js"></script>
</head>
<body>
<table id="dg" style="style=" width:400px;height:200px;
"></table>
<div id="tb">
<input class="easyui-textbox" id="oid" name="oid" style="width:20%;padding-left: 10px" data-options="label:'订单号:',required:true">
<a id="btn-search" href="#" class="easyui-linkbutton" data-options="iconCls:'icon-search'">搜索</a>
</div>
<script>
$(function () {
$("#btn-search").click(function () {
$('#dg').datagrid('load', {
oid: $("#oid").val()
});
});
$('#dg').datagrid({
url: '${pageContext.request.contextPath}/orderItem.action?methodName=list',
fit: true,
fitColumns: true,
pagination: true,
singleSelect: true,
toolbar:'#tb',
columns: [[
// {field:'id',title:'id',width:100},
{field: 'id', title: '订单项流水号', hidden: true},
{field: 'oid', title: '订单号', width: 50},
{field: 'bid', title: '书籍名称', width: 50},
{field: 'quantity', title: '数量', width: 50}
]]
});
})
</script>
</body>
</html>
?2、订单项OrderItemDao方法
/**
* 通过外键的订单id查询订单项
* @param orderItem
* @param pageBean
* @return
* @throws Exception
*/
public List<OrderItem> list(OrderItem orderItem, PageBean pageBean) throws Exception {
String sql = "select * from t_easyui_orderItem where 1=1";
//oid是订单项的外键，关联了订单表的主键
long oid=orderItem.getOid();
if(oid != 0) {
sql += " and oid ="+oid;
}
return super.executeQuery(sql,OrderItem.class, pageBean);
}
3、子控制器OrderItemAction
package com.zking.web;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.zking.framework.ActionSupport;
import com.zking.framework.ModelDriver;
import com.zking.util.PageBean;
import com.zking.util.R;
import com.zking.util.ResponseUtil;
import com.zking.dao.OrderItemDao;
import com.zking.entity.OrderItem;
public class OrderItemAction extends ActionSupport implements ModelDriver<OrderItem>{
private OrderItem orderItem = new OrderItem();
private OrderItemDao orderItemDao = new OrderItemDao();
public OrderItem getModel() {
return orderItem;
}
public String list(HttpServletRequest req, HttpServletResponse resp) {
PageBean pageBean =new PageBean();
pageBean.setRequest(req);
try {
List<OrderItem> list=orderItemDao.list(orderItem, pageBean);
ResponseUtil.writeJson(resp, new R().data("total",pageBean.getTotal()).data("rows",list));
} catch (Exception e) {
e.printStackTrace();
}
return super.execute(req, resp);
}
}
4、配置mvc.xml
<action type="com.zking.web.OrderItemAction" path="/orderItem">
</action>
