## 步驟 1 : 先運行，看到效果，再學習
先將完整的 tmall_ssm 項目（向老師要相關資料），配置運行起來，確認可用之后，再學習做了哪些步驟以達到這樣的效果。
## 步驟 2 : 模仿和排錯
在確保可運行項目能夠正確無誤地運行之后，再嚴格照著教程的步驟，對代碼模仿一遍。
模仿過程難免代碼有出入，導致無法得到期望的運行結果，此時此刻通過比較**正確答案** ( 可運行項目 ) 和自己的代碼，來定位問題所在。
采用這種方式，**學習有效果，排錯有效率**，可以較為明顯地提升學習速度，跨過學習路上的各個檻。
## 步驟 3 : 我的訂單頁面操作
在我的訂單頁面，根據訂單的不同狀態，可以做出如下不同的操作：
1. 付款 —— 已經生成，但是未付款
2. 確認收貨 —— 通過**后臺發貨**后
3. 評價 —— 確認收貨后, 將在**評價產品**知識點講解，這里只是提到
4. 刪除 —— 任意狀態下
## 步驟 4 : 付款
點擊付款按鈕直接跳轉到在生成訂單中的確認支付頁環節，屬于已經開發的功能，在此不作贅述。
## 步驟 5 : 確認收貨
1. 點擊確認收貨后，訪問地址`/foreconfirmPay`
2. `ForeController.confirmPay()`方法被調用
2.1 獲取參數oid
2.2 通過oid獲取訂單對象o
2.3 為訂單對象填充訂單項
2.4 把訂單對象放在request的屬性"o"上
2.5 服務端跳轉到 confirmPay.jsp
3. confirmPay.jsp
與 register.jsp 相仿，confirmPay.jsp也包含了header.jsp, top.jsp, simpleSearch.jsp， footer.jsp 等公共頁面。
中間是訂單確認業務頁面 confirmPayPage.jsp
4. confirmPayPage.jsp
顯示訂單的創建時間，付款時間和發貨時間，以及訂單號，收款人信息等
遍歷訂單項集合，顯示其中的產品圖片，產品標題，價格，數量，小計，總結信息
最后提供確認支付按鈕，提交到`/foreorderconfirmed`路徑

## 步驟 6 : 確認收貨成功
通過上一步最后的確認支付按鈕，提交到路徑`/foreorderConfirmed`，導致`ForeController.orderConfirmed()`方法被調用
1. `ForeController.orderConfirmed()` 方法
1.1 獲取參數oid
1.2 根據參數oid獲取Order對象o
1.3 修改對象o的狀態為等待評價，修改其確認支付時間
1.4 更新到數據庫
1.5 服務端跳轉到orderConfirmed.jsp頁面
2. orderConfirmed.jsp
與 register.jsp 相仿，orderConfirmed.jsp也包含了header.jsp, top.jsp, simpleSearch.jsp， footer.jsp 等公共頁面。
中間是確認收貨成功業務頁面 orderConfirmedPage.jsp
3. orderConfirmedPage.jsp
顯示"交易已經成功，賣家將收到您的貨款。"
orderConfirmed()方法：
~~~
@RequestMapping("foreorderConfirmed")
public String orderConfirmed(Model model, int oid) {
Order o = orderService.get(oid);
o.setStatus(OrderService.waitReview);
o.setConfirmDate(new Date());
orderService.update(o);
return "fore/orderConfirmed";
}
~~~

## 步驟 7 : 評價
點擊評價按鈕，跳轉到路徑`/forereview`,這部分單獨開了個知識點**評價產品**進行講解。
## 步驟 8 : 刪除
在我的訂單頁 上點擊刪除按鈕，根據 boughtPage.jsp 中的ajax操作，會訪問路徑/foredeleteOrder，導致ForeController.deleteOrder方法被調用
1. ForeController.deleteOrder()
1.1 獲取參數oid
1.2 根據oid獲取訂單對象o
1.3 修改狀態
1.4 更新到數據庫
1.5 返回字符串"success"
2. boughtPage.jsp 中的javascript代碼獲取返回字符串是success的時候，移除掉當前這行訂單數據。
~~~
var page = "foredeleteOrder";
$.post(page, {
"oid" : deleteOrderid
}, function(result) {
if ("success" == result) {
$("table.orderListItemTable[oid=" + deleteOrderid + "]").remove();
} else {
location.href = "login.jsp";
}
});
~~~
deleteOrder方法：
~~~
@RequestMapping("foredeleteOrder")
@ResponseBody
public String deleteOrder(Model model, int oid) {
Order o = orderService.get(oid);
o.setStatus(OrderService.delete);
orderService.update(o);
return "success";
}
