1.项目分析
商城实体: 用户 商品 订单 分类
实体关系: 用户和订单:一对多 商品和订单:多对多 分类和商品:一对多
今日任务: 用户模块开发 注册 用户激活 用户登录 用户退出
2.新建项目 导入jar包 驱动 c3p0 dbutils beanutils jstl mail 导入配置文件和工具类 导入页面
3.新建包结构:
com.itheima.service
com.itheima.service.impl //处理业务包
com.itheima.dao
com.itheima.dao.impl //model层处理数据库
com.itheima.web.servlet //控制类、control
com.itheima.web.filter //处理类
com.itheima.domain //实体类
com.itheima.utils //工具类
com.itheima.constant //常量类
4.servlet抽取: 前三条是弊端
1.doget每次请求都会执行--- 重写service
2.用了大量 if else if 判断执行的是那个方法让方法执行
Method method = this.getClass().getMethod(mt, HttpServletRequest.class,HttpServletResponse.class);
method.invoke(this, request,response);
3.每个方法执行的结果无非就是请求转发或者重定向或者打印数据 让所有的方法都返回一个字符串 若最后的结果需要请求转发,就把转发的路径给返回
若最后的结果不需要请求转发,就返回一个null
Method method = this.getClass().getMethod(mName, HttpServletRequest.class,HttpServletResponse.class);
//3.让方法执行,接受返回值
String path=(String) method.invoke(this, request,response);
4.所有servlet的service中的代码都一样 向上继续抽取编写一个BaseServlet,将之前service方法中的代码复制过来即可, 然所有的servlet都继承baseservlet即可
5.统一的错误页面
5. 模块实现
数据库用户表字段： user表 uid 用户主键id username、password、name、email、telephone、birthday、sex、
state、用户状态是否激活 0未激活 1激活 code 根据此激活状态码
案例1-用户注册
1.设置默认首页(index.jsp),让其自动的跳转到/jsp/index.jsp
2.修 改index.jsp上的 注册 连接<a href='/store/user?method=registUI'>注册</a>
3.在userservlet中编写reigstUI方法 请求转发到 /jsp/register.jsp
4.修改register.jsp上的表单信息action ="/store/user?method=regist" method为每一个子标签添加name属性
5.点击注册按钮 向userservlet发送请求
6.userservlet中编写regist方法 获取参数,封装成user对象调用service完成注册 生成提示信息,转发 /jsp/msg.jsp
7.userservice中的操作:调用dao完成注册操作发送邮件
8.userdao...
案例2-用户激活
需求 : 用户登录邮箱之后,点击邮箱中的连接,完成用户激活操作
步骤分析:
1.点击邮箱中的连接 ,向商城userservlet发送一个请求 user?method=active&coed=xxxx
2.在userservlet中编写active方法接受code 调用service完成激活 返回值:user 生成提示信息 转发
3.在service中编写激活方法 通过code获取用户 若没有找到:提示重新激活或者重新注册若找到了 设置激活状态 1将code设置为null
4.在dao需要编写两个方法 getByCode update
案例3-用户登录
需求: 在一个登录页面上,输入用户名和密码,点击登录,完成登录操作 随机验证码实现
步骤分析:
1.在index.jsp点击 登录 连接,跳转到登录页面
2.在userserlvet中编写 loginUI
3.修改login.jsp表单的信息 action: /user?method=login method 给子标签添加name属性
4.点击提交发送请求
5.在userservlet中编写login方法 获取用户名和密码 调用service完成登录 返回值:user 若登录成功,跳转到index.jsp 并展示用户信息 若登录失败,
若user为空:提示 用户名和密码 跳转到login.jsp 若user不为空但是未激活:提示信息 "请先去邮箱激活,再登录" 跳转msg.jsp
6.service,dao
案例4-用户退出
需求: 点击 index.jsp上 退出连接,退出当前的用户,跳转index.jsp
步骤分析:
1.点击 index.jsp上 退出 连接,向userservlet发送请求 /user?methode=logout
2.在userservlet中编写logout方法 销毁session 重定向到index.jsp
案例5- 扩展 记住用户名:
需求: 登录成功之后,若勾选了记住用户名,下一次再登录的时候,会展示出来用户名
步骤分析:修改login方法的逻辑 登录成功之后,判断是否勾选了记住用户名
若勾选了,将用户名(将用户名编码)保存到cookie中 在login.jsp加载成功的时候需要从cookie中获取用户名且展示出来
案例6--baseservlet的抽取
6.代码区
