[TOC] ## 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 : 結算頁操作 首先通過立即購買或者購物車的提交到結算頁面 進入結算頁面，然后點擊提交訂單  ## 步驟 4 : 運行效果 提交訂單后，在數據庫中生成一條Order記錄。 不僅如此，訂單項的oid字段也會被設置為這條Order記錄的id  ## 步驟 5 : applicationContext.xml 在最后增加事務管理配置： ~~~ <!--事務管理 --> <tx:annotation-driven transaction-manager="transactionManager" /> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> ~~~ 因為增加訂單行為需要同時修改兩個表 1. 為Order表新增數據 2. 修改OrderItem表 所以需要進行事務管理，否則當新增了Order表的數據，還沒有來得及修改OrderItem的時候出問題，比如突然斷電，那么OrderItem的數據就會是臟數據了（沒有指向正確的Order表數據）。 ~~~ <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"> <context:annotation-config /> <context:component-scan base-package="com.dodoke.tmall.service" /> <!-- 導入數據庫配置文件 --> <context:property-placeholder location="classpath:jdbc.properties" /> <!-- 配置數據庫連接池 --> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"> <!-- 基本屬性 url、user、password --> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <!-- 配置初始化大小、最小、最大 --> <property name="initialSize" value="1" /> <property name="minIdle" value="1" /> <property name="maxActive" value="20" /> <!-- 配置獲取連接等待超時的時間 --> <property name="maxWait" value="60000" /> <!-- 配置間隔多久才進行一次檢測，檢測需要關閉的空閑連接，單位是毫秒 --> <property name="timeBetweenEvictionRunsMillis" value="60000" /> <!-- 配置一個連接在池中最小生存的時間，單位是毫秒 --> <property name="minEvictableIdleTimeMillis" value="300000" /> <property name="validationQuery" value="SELECT 1" /> <property name="testWhileIdle" value="true" /> <property name="testOnBorrow" value="false" /> <property name="testOnReturn" value="false" /> <!-- 打開PSCache，并且指定每個連接上PSCache的大小 --> <property name="poolPreparedStatements" value="true" /> <property name="maxPoolPreparedStatementPerConnectionSize" value="20" /> </bean> <!--Mybatis的SessionFactory配置 --> <bean id="sqlSession" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="typeAliasesPackage" value="com.dodoke.tmall.pojo" /> <property name="dataSource" ref="dataSource" /> <property name="mapperLocations" value="classpath:mapper/*.xml" /> <!--分頁插件，目前先注釋，后面重構的時候才會使用 --> <property name="plugins"> <array> <bean class="com.github.pagehelper.PageInterceptor"> <property name="properties"> <value> </value> </property> </bean> </array> </property> </bean> <!--Mybatis的Mapper文件識別 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.dodoke.tmall.mapper" /> </bean> <!--事務管理 --> <tx:annotation-driven transaction-manager="transactionManager" /> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> </beans> ~~~ ## 步驟 6 : OrderService 新增方法 `add(Order c,List<OrderItem> ois);` ~~~ package com.dodoke.tmall.service; import java.util.List; import com.dodoke.tmall.pojo.Order; import com.dodoke.tmall.pojo.OrderItem; public interface OrderService { String waitPay = "waitPay"; String waitDelivery = "waitDelivery"; String waitConfirm = "waitConfirm"; String waitReview = "waitReview"; String finish = "finish"; String delete = "delete"; void add(Order c); void delete(int id); void update(Order c); Order get(int id); List list(); List list(int uid, String excludedStatus); float add(Order c,List<OrderItem> ois); } ~~~ ## 步驟 7 : OrderServiceImpl 實現`add(Order o, List<OrderItem> ois)`方法，該方法通過注解進行事務管理 ~~~ @Transactional(propagation= Propagation.REQUIRED,rollbackForClassName="Exception") ~~~ 下列代碼用來模擬當增加訂單后出現異常，觀察事務管理是否預期發生。（需要把false修改為true才能觀察到） ~~~ if(false) throw new RuntimeException(); ~~~ OrderServiceImpl.java： ~~~ package com.dodoke.tmall.service.impl; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service;

add(o); if(false) throw new RuntimeException(); for (OrderItem oi: ois) { oi.setOrderId(o.getId()); orderItemService.update(oi); total+=oi.getProduct().getPromotePrice()*oi.getNumber(); } return total; } } ~~~ ## 步驟 8 : ForeController.createOrder 提交訂單訪問路徑 `/forecreateOrder`, 導致`ForeController.createOrder` 方法被調用。 1. 從session中獲取user對象 2. 通過參數Order接受地址，郵編，收貨人，用戶留言等信息 3. 根據當前時間加上一個4位隨機數生成訂單號 4. 根據上述參數，創建訂單對象 5. 把訂單狀態設置為等待支付 6. 從session中獲取訂單項集合 ( 在`結算功能的ForeController.buy() `中，訂單項集合被放到了session中 ) 7. 把訂單加入到數據庫，并且遍歷訂單項集合，設置每個訂單項的order，更新到數據庫 8. 統計本次訂單的總金額 9. 客戶端跳轉到確認支付頁forealipay，并帶上訂單id和總金額 ~~~ package com.dodoke.tmall.controller;
