## 步骤 1 : 先运行，看到效果，再学习
先将完整的 tmall_ssm 项目（向老师要相关资料），配置运行起来，确认可用之后，再学习做了哪些步骤以达到这样的效果。
## 步骤 2 : 模仿和排错
在确保可运行项目能够正确无误地运行之后，再严格照着教程的步骤，对代码模仿一遍。
模仿过程难免代码有出入，导致无法得到期望的运行结果，此时此刻通过比较**正确答案** ( 可运行项目 ) 和自己的代码，来定位问题所在。
采用这种方式，**学习有效果，排错有效率**，可以较为明显地提升学习速度，跨过学习路上的各个槛。
## 步骤 3 : 界面效果
## 步骤 4 : 评价产品页面
通过点击评价按钮，来到路径`/forereview`，导致ForeController.review()方法被调用
1. ForeController.review()
1.1 获取参数oid
1.2 根据oid获取订单对象o
1.3 为订单对象填充订单项
1.4 获取第一个订单项对应的产品,因为在评价页面需要显示一个产品图片，那么就使用这第一个产品的图片了
1.5 获取这个产品的评价集合
1.6 为产品设置评价数量和销量
1.7 把产品，订单和评价集合放在request上
1.8 服务端跳转到 review.jsp
2. review.jsp
与 register.jsp 相仿，review.jsp也包含了header.jsp, top.jsp, simpleSearch.jsp，
footer.jsp 等公共页面。
中间是产品业务页面 reviewPage.jsp
3. reviewPage.jsp
在reviewPage.jsp中显示产品图片，产品标题，价格，产品销量，产品评价数量，以及订单信息等。
同时还显示出了该产品所有的评价，但是默认是隐藏的
ForeController.review()：

@RequestMapping("forereview")

Order o = orderService.get(oid);
orderItemService.fill(o);

## 步骤 5 : 提交评价
在评价产品页面点击提交评价，就把数据提交到了`/foredoreview`路径，导致`ForeController.doreview`方法被调用
1. `ForeController.doreview()`
1.1 获取参数oid
1.2 根据oid获取订单对象o
1.3 修改订单对象状态
1.4 更新订单对象到数据库
1.5 获取参数pid
1.6 根据pid获取产品对象
1.7 获取参数content (评价信息)
1.8 对评价信息进行转义，道理同注册`ForeController.register()`
1.9 从session中获取当前用户
1.10 创建评价对象review
1.11 为评价对象review设置 评价信息，产品，时间，用户
1.12 增加到数据库
1.13.客户端跳转到`/forereview`： 评价产品页面，并带上参数`showonly=true`
2. reviewPage.jsp
在reviewPage.jsp中，当参数showonly==true，那么就显示当前产品的所有评价信息

@RequestMapping("foredoreview")
public String doreview(Model model, HttpSession session, @RequestParam("oid") int oid, @RequestParam("pid") int pid,

Product p = productService.get(pid);
content = HtmlUtils.htmlEscape(content);
User user = (User) session.getAttribute("user");
Review review = new Review();
review.setContent(content);
review.setProductId(pid);
review.setCreateDate(new Date());
review.setUserId(user.getId());
reviewService.add(review);
