1、现在要为user用户模块创建类
用户模块功能包括：注册、激活、登录、退出、修改密码。
User类对照着t_user表来写即可。我们要保证User类的属性名称与t_user表的列名称完全相同。
我们来创建User类
package com.weiyuan.goods.user.domian;
public class User {
private String uid; //主键
private String loginname;// 登陆名称
private String loginpass;// 登陆密码
private String email;//注册的邮箱
private String verifyCode; //验证码
private boolean status;//是否激活
private String activationCode;//激活码
public String getUid() {
return uid;
}
public void setUid(String uid) {
this.uid = uid;
}
public String getLoginname() {
return loginname;
}
public void setLoginname(String loginname) {
this.loginname = loginname;
}
public String getLoginpass() {
return loginpass;
}
public void setLoginpass(String loginpass) {
this.loginpass = loginpass;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getVerifyCode() {
return verifyCode;
}
public void setVerifyCode(String verifyCode) {
this.verifyCode = verifyCode;
}
public boolean isStatus() {
return status;
}
public void setStatus(boolean status) {
this.status = status;
}
public String getActivationCode() {
return activationCode;
}
public void setActivationCode(String activationCode) {
this.activationCode = activationCode;
}
@Override
public String toString() {
return "User [uid=" + uid + ", loginname=" + loginname + ", loginpass="
+ loginpass + ", email=" + email + ", verifyCode=" + verifyCode
+ ", status=" + status + ", activationCode=" + activationCode
+ "]";
}
}
数据库接口类：
UserDao封装了对数据库的基本操作。UserDao需要使用TxQueryRunner来完成对数据库的操作。
package com.weiyuan.goods.user.dao;
import cn.itcast.jdbc.TxQueryRunner;
public class UserDao {
//操作数据库
private TxQueryRunner qr = new TxQueryRunner();
}
业务层操作类：
UserService封装了业务功能，在UserService中每个方法对应一个业务功能，例如：注册方法、登录方法等等。一个业务方法可能需要多次调用DAO中的方法！所以，Service依赖Dao，我们需要在UserService中给出一个UserDao类型的成员。
package com.weiyuan.goods.user.service;
import com.weiyuan.goods.user.dao.UserDao;
public class UserService {
private UserDao dao = new UserDao();
}
控制层servlet，该servlet继承小工具类中BaseServlet，
UserServlet用来接收客户端请求，处理与WEB相关的问题。例如获取客户端的请求参数，然后转发或重定向等。在UserServlet中完成业务功能需要使用UserService，所以我们需要在UserServlet中给出一个UserService的成员。
因为可以让一个Servlet中有多个请求处理方法，我们让UserServlet继承BaseServlet！
UserServlet.java
package com.weiyuan.goods.user.web.servlet; import java.io.IOException; import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse; import cn.itcast.servlet.BaseServlet; /**
* Servlet implementation class UserServlet
*/
@WebServlet("/UserServlet")
public class UserServlet extends BaseServlet{
private static final long serialVersionUID = 1L; /**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
} /**
* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
} }
