商城系统后台管理订单模块分析

订单管理后台模块

恳求地址

http://localhost:8080/tmall/admin/order

恳求方式get方式

说明：此时对应后台订单管理的模块部分主要集中在了ordercontroller这一个控制器中
后台管理全部订单模块页面跳转

//转到后台管理-订单页-ajax@RequestMapping(value ="admin/order", method =RequestMethod.GET)publicStringgoToPage(HttpSession session,Map<String,Object> map){
logger.info("获取前10条订单列表");PageUtil pageUtil =newPageUtil(0,10);List<ProductOrder> productOrderList =
productOrderService.getList(null,null,newOrderUtil("productOrder_id",true), pageUtil);
map.put("productOrderList",productOrderList);
logger.info("获取订单总数量");Integer productOrderCount = productOrderService.getTotal(null,null);
map.put("productOrderCount", productOrderCount);
logger.info("获取分页信息");
pageUtil.setTotal(productOrderCount);
map.put("pageUtil", pageUtil);
logger.info("转到后台管理-订单页-ajax方式");return"admin/orderManagePage";}

断点调试跳转到后台管理订单页

查询出第一次分页所需要的数据

之后封装信息完成页面的跳转
分页数据的切换
恳求途径
http://localhost:8080/tmall/admin/order/1/10?productOrder_code=&productOrder_post=&productOrder_status_array=&orderBy=&isDesc=true
GET
依照条件查询数据

@ResponseBody@RequestMapping(value ="admin/order/{index}/{count}", method =RequestMethod.GET, produces ="application/json;charset=UTF-8")publicStringgetOrderBySearch(@RequestParam(required =false)String productOrder_code/* 订单号 */,@RequestParam(required =false)String productOrder_post/* 订单邮政编码 */,@RequestParam(required =false)Byte[] productOrder_status_array/* 订单状态数组 */,@RequestParam(required =false)String orderBy/* 排序字段 */,@RequestParam(required =false,defaultValue ="true")Boolean isDesc/* 是否倒序 */,@PathVariableInteger index/* 页数 */,@PathVariableInteger count/* 行数 */){//移除不用要条件if(productOrder_status_array !=null&&(productOrder_status_array.length <=0|| productOrder_status_array.length >=5)){
productOrder_status_array =null;}if(productOrder_code !=null){
productOrder_code ="".equals(productOrder_code)?null: productOrder_code;}if(productOrder_post !=null){
productOrder_post ="".equals(productOrder_post)?null: productOrder_post;}if(orderBy !=null&&"".equals(orderBy)){
orderBy =null;}//封装查询条件ProductOrder productOrder =newProductOrder().setProductOrder_code(productOrder_code).setProductOrder_post(productOrder_post);OrderUtil orderUtil =null;if(orderBy !=null){
logger.info("根据{}排序，是否倒序:{}",orderBy,isDesc);
orderUtil =newOrderUtil(orderBy, isDesc);}else{
orderUtil =newOrderUtil("productOrder_id",true);}JSONObject object =newJSONObject();
logger.info("按条件获取第{}页的{}条订单", index +1, count);PageUtil pageUtil =newPageUtil(index, count);List<ProductOrder> productOrderList = productOrderService.getList(productOrder, productOrder_status_array, orderUtil, pageUtil);
object.put("productOrderList",JSONArray.parseArray(JSON.toJSONString(productOrderList)));
logger.info("按条件获取订单总数量");Integer productOrderCount = productOrderService.getTotal(productOrder, productOrder_status_array);
object.put("productOrderCount", productOrderCount);
logger.info("获取分页信息");
pageUtil.setTotal(productOrderCount);
object.put("totalPage", pageUtil.getTotalPage());
object.put("pageUtil", pageUtil);return object.toJSONString();}

断点调试依照条件来查询订单

难点在于移除条件，在整个项目中发挥了什么作用。

productOrder_code ="".equals(productOrder_code)?null: productOrder_code;
复制代码

在参数没有提交的情况下,将空格条件转化为null
订单详情页显示

难点在与循环倒序的拼接出详细的地址

//假设不是第一级地址，循环拼接地址信息while(!address.getAddress_areaId().equals(address.getAddress_regionId().getAddress_areaId())){
address = addressService.get(address.getAddress_regionId().getAddress_areaId());
addressStack.push(address.getAddress_name()+" ");}

复制代码

相等即为一级地址

Stack<String> addressStack = new Stack<>();
//创建一个String类型的栈实例

复制代码

//转到后台管理-订单详情页-ajax@RequestMapping(value ="admin/order/{oid}", method =RequestMethod.GET)publicStringgoToDetailsPage(HttpSession session,Map<String,Object> map,@PathVariableInteger oid/* 订单ID */){
logger.info("获取order_id为{}的订单信息",oid);ProductOrder order = productOrderService.get(oid);
logger.info("获取订单详情-地址信息");Address address = addressService.get(order.getProductOrder_address().getAddress_areaId());Stack<String> addressStack =newStack<>();//详细地址
addressStack.push(order.getProductOrder_detail_address());//最后一级地址
addressStack.push(address.getAddress_name()+" ");//假设不是第一级地址，循环拼接地址信息while(!address.getAddress_areaId().equals(address.getAddress_regionId().getAddress_areaId())){
address = addressService.get(address.getAddress_regionId().getAddress_areaId());
addressStack.push(address.getAddress_name()+" ");}StringBuilder builder =newStringBuilder();while(!addressStack.empty()){
builder.append(addressStack.pop());}
logger.info("订单地址字符串：{}", builder);
order.setProductOrder_detail_address(builder.toString());
logger.info("获取订单详情-用户信息");
order.setProductOrder_user(userService.get(order.getProductOrder_user().getUser_id()));
logger.info("获取订单详情-订单项信息");List<ProductOrderItem> productOrderItemList = productOrderItemService.getListByOrderId(oid,null);if(productOrderItemList !=null){
logger.info("获取订单详情-订单项对应的产品信息");for(ProductOrderItem productOrderItem : productOrderItemList){Integer productId = productOrderItem.getProductOrderItem_product().getProduct_id();
logger.info("获取产品ID为{}的产品信息", productId);Product product = productService.get(productId);if(product !=null){
logger.info("获取产品ID为{}的第一张预览图片信息", productId);
product.setSingleProductImageList(productImageService.getList(productId,(byte)0,newPageUtil(0,1)));}
productOrderItem.setProductOrderItem_product(product);}}
order.setProductOrderItemList(productOrderItemList);
map.put("order", order);
logger.info("转到后台管理-订单详情页-ajax方式");return"admin/include/orderDetails";}

复制代码

跳转到前端jsp地址admin/include/orderDetails

//单击发货按钮时
$("#btn_order_save").click(function (){var order_id = '${requestScope.order.productOrder_id}';
$.ajax({
url:"admin/order/"+ order_id,
type:"PUT",
data:null,
success: function (data){
$("#btn_order_save").remove();if(data.success){
$("#btn-ok,#btn-close").unbind("click").click(function (){
$('#modalDiv').modal("hide");setTimeout(function (){//ajax恳求页面
ajaxUtil.getPage("order/"+ data.order_id,null,true);},170);});
$(".modal-body").text("发货胜利！");
$('#modalDiv').modal();}},
beforeSend: function (){
$("#btn_order_save").attr("disabled",true).val("发货中...");},
error: function (){}});});});

复制代码

其他点击时可以通过jsp发送的ajax恳务实现页面的定向跳转

<div class="details_tools_div">
<c:if test="${requestScope.order.productOrder_status==1}">
<input class="frm_btn" id="btn_order_save" type="button" value="发货"/>
</c:if>
<input class="frm_btn frm_clear" id="btn_order_cancel" type="button" value="取消"/>
</div>

复制代码

根据c-if标签停止动态显示
发货时更新状态的信息

同时更新状态值为2，在将时间停止更新

//更新订单信息-ajax
@ResponseBody
@RequestMapping(value = "admin/order/{order_id}", method = RequestMethod.PUT, produces = "application/json;charset=UTF-8")
public String updateOrder(@PathVariable("order_id") String order_id) {
JSONObject jsonObject = new JSONObject();
logger.info("整合订单信息");
ProductOrder productOrder = new ProductOrder()
.setProductOrder_id(Integer.valueOf(order_id))
.setProductOrder_status((byte) 2)
.setProductOrder_delivery_date(new Date());
logger.info("更新订单信息，订单ID值为：{}", order_id);
boolean yn = productOrderService.update(productOrder);
if (yn) {
logger.info("更新胜利！");
jsonObject.put("success", true);
} else {
logger.info("更新失败！事务回滚");
jsonObject.put("success", false);
throw new RuntimeException();
}
jsonObject.put("order_id", order_id);
return jsonObject.toJSONString();
}
