订单管理实现

一.目的以及实现思路
商家：①查看订单

         ②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）

         ③订单项查看
思路：订单表的查询，将订单表的订单状态由1改为2通过订单的id到订单项表查询出对应的订单
买家：①查看订单
         ②撤单
         ③签收
思路：订单表的查询，将订单表的订单状态由1改为4，将订单表的订单状态由2改为3

  二，订单管理

1，JSP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>
<script>
$(function () {
$('#dg').datagrid({
url: '${pageContext.request.contextPath}/order.action?methodName=list&&orderState=1',
fit: true,
fitColumns: true,
pagination: true,
singleSelect: true,
columns: [[
// {field:'id',title:'id',width:100},
{field: 'id', title: '书籍名称', hidden: true},
{field: 'postalcode', title: '收货人邮编', hidden: true},
{field: 'uid', title: '用户', width: 50},
{field: 'consignee', title: '收货人', width: 50},
{field: 'phone', title: '手机号', width: 50},
{field: 'address', title: '收获人地址', width: 50},
{field: 'orderPrice', title: '价格', width: 50},
{field: 'sendTime', title: '发货时间', width: 50},
{field: 'orderTime', title: '订单时间', width: 50},
{
field: 'sendType', title: '发送方式', width: 50, formatter: function (value, row, index) {
if (row.sendType == 1) {
return "平邮";
} else if (row.sendType == 2) {
return "快递";
}
}
},
{
field: 'orderState', title: '订单状态', width: 100, formatter: function (value, row, index) {
if (row.orderState == 1) {
return "未发货";
} else if (row.orderState == 2) {
return "已发货";
} else if (row.orderState == 3) {
return "已签收";
} else if (row.orderState == 4) {
return "已撤单";
}
}
},
{
field: 'xxxx', title: '操作', width: 100, formatter: function (value, row, index) {
return '<a href="#" onclick="cancel();">撤单</a>';
}
}
]]
});
})
function cancel() {
var row = $('#dg').datagrid('getSelected');
var id=0;
if (row) {
id = row.id;
}else {
alert("请勾选数据...");
return;
}
$.messager.confirm('确认', '您确认想要撤单吗？', function (r) {
if (r) {
$.ajax({
url: '${pageContext.request.contextPath}/order.action?methodName=cancelAndReceive&&orderState=4&id='+id,
success: function (data) {
$('#dg').datagrid('reload');
}
});
}
})
}
</script>
</body>
</html>

2.order查询与修改状态的方法

/**
* 依照订单时间倒序查询：需要设置当前订单项是属于哪个订单的,思路是查询出最新订单的id
* @param order
* @param pageBean
* @return
* @throws Exception
*/
public List<Order> list( Order order, PageBean pageBean) throws Exception {
String sql="select * from t_easyui_order where 1=1 ";
long id = order.getId();
if(id!=0) {
sql+=" and id="+id;
}
//用来根据状态查询
int orderState = order.getOrderState();
if(orderState !=0) {
sql+=" and orderState="+orderState;
}
sql+=" order by orderTime desc";
return super.executeQuery(sql, Order.class, pageBean);
}
/**
* 修改订单状态
*
*/
public void editState( Order t) throws Exception {
String sql="update t_easyui_order set orderState=? where id=?";
//假设是发货，那么还需要修改发货时间
int orderState = t.getOrderState();
if(orderState ==2) {
sql="update t_easyui_order set orderState=?,sendTime=now() where id=?";
}
super.executeUpdate(sql, t, new String[] {"orderState","id"});
}

3，子控制器

public class OrderAction extends ActionSupport implements ModelDriver<Order>{
private Order order=new Order();
private OrderDao orderDao=new OrderDao();
@Override
public Order getModel() {
// TODO Auto-generated method stub
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) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
/**
* 关于发货，撤单。签收的公用方法
* @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) {
// TODO Auto-generated catch block
e.printStackTrace();
try {
ResponseUtil.writeJson(resp,0);
} catch (Exception e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
}
}

配置：

<action path="/order" type="com.xyy.web.OrderAction">
</action>

运行结果：

三，订单项管理

1，JSP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，dao方法

public class OrderItemDao extends BaseDao<OrderItem>{
/**
* 购物车结算订单项数据入库
* @param t
* @throws Exception
*/
public void add( OrderItem t) throws Exception {
String sql="insert into t_easyui_orderItem(oid,bid,quantity) values(?,?,?)";
super.executeUpdate(sql, t,new String[] {"oid","bid","quantity"});
}
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的是订单表的主键
long oid = orderItem.getOid();
if(oid!=0) {
sql+=" and oid="+oid;
}
return super.executeQuery(sql, OrderItem.class, pageBean);
}
}

复制代码

3，子控制器

public class OrderItemAction extends ActionSupport implements ModelDriver<OrderItem>{
private OrderItem orderItem=new OrderItem();
private OrderItemDao orderItemDao=new OrderItemDao();
@Override
public OrderItem getModel() {
// TODO Auto-generated method stub
return orderItem;
}
public void 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) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

复制代码

4，配置

<action path="/orderItem" type="com.xyy.web.OrderItemAction">
</action>

运行结果：
