一：创建实体类：
1 import java.io.Serializable;
2
3 public class Customer implements Serializable {
4 private String id;
5 private String username;
6 private String password;
7 private String phone;
8 private String address;
9 private String email;
10 private boolean actived;//是否激活
11 private String code;//激活码
12 public String getId() {
13 return id;
14 }
15 public void setId(String id) {
16 this.id = id;
17 }
18 public String getUsername() {
19 return username;
20 }
21 public void setUsername(String username) {
22 this.username = username;
23 }
24 public String getPassword() {
25 return password;
26 }
27 public void setPassword(String password) {
28 this.password = password;
29 }
30 public String getPhone() {
31 return phone;
32 }
33 public void setPhone(String phone) {
34 this.phone = phone;
35 }
36 public String getAddress() {
37 return address;
38 }
39 public void setAddress(String address) {
40 this.address = address;
41 }
42 public String getEmail() {
43 return email;
44 }
45 public void setEmail(String email) {
46 this.email = email;
47 }
48 public boolean isActived() {
49 return actived;
50 }
51 public void setActived(boolean actived) {
52 this.actived = actived;
53 }
54 public String getCode() {
55 return code;
56 }
57 public void setCode(String code) {
58 this.code = code;
59 }
60
61 }
Customer
二：创建注册界面：
1 <h1>新用户注册</h1>
2 <form action="${pageContext.request.contextPath}/servlet/ControllerServlet?op=regist" method="post">
3 <table border="1" width="438">
4 <tr>
5 <td>(*)用户名：</td>
6 <td>
7 <input type="text" name="username"/>
8 </td>
9 </tr>
10 <tr>
11 <td>(*)密码：</td>
12 <td>
13 <input type="password" name="password"/>
14 </td>
15 </tr>
16 <tr>
17 <td>重复密码：</td>
18 <td>
19 <input type="password" name="repassword"/>
20 </td>
21 </tr>
22 <tr>
23 <td>(*)电话：</td>
24 <td>
25 <input type="text" name="phone"/>
26 </td>
27 </tr>
28 <tr>
29 <td>(*)收货地址：</td>
30 <td>
31 <input type="text" name="address"/>
32 </td>
33 </tr>
34 <tr>
35 <td>(*)邮箱：</td>
36 <td>
37 <input type="text" name="email"/>
38 </td>
39 </tr>
40 <tr>
41 <td colspan="2">
42 <input type="submit" value="注册"/>
43 </td>
44 </tr>
45 </table>
46 </form>
RegistPage.jsp
1 <h1>用户登入</h1>
2 <form action="${pageContext.request.contextPath}/servlet/ControllerServlet?op=login" method="post">
3 <table border="1" width="438">
4 <tr>
5 <td>(*)用户名：</td>
6 <td>
7 <input type="text" name="username"/>
8 </td>
9 </tr>
10 <tr>
11 <td>(*)密码：</td>
12 <td>
13 <input type="password" name="password"/>
14 </td>
15 </tr>
16 <tr>
17 <td colspan="2">
18 <input type="submit" value="登录"/>
19 </td>
20 </tr>
21 </table>
22 </form>
LoginPage.jsp
三：创建控制器：
控制器：servlet：controller
1 public class ControllerServlet extends HttpServlet {
2 private BusinessService s = new BusinessServiceImpl();
3 public void doGet(HttpServletRequest request, HttpServletResponse response)
4 throws ServletException, IOException {
5 String op = request.getParameter("op");
6 if("regist".equals(op)){
7 regist(request,response);
8 }else if("login".equals(op)){
9 login(request,response);
10 }else if("logout".equals(op)){
11 logout(request,response);
12 }else if("active".equals(op)){
13 active(request,response);
14 }
15 }
16 //激活账户
17 private void active(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {
18 String username = request.getParameter("username");
19 String code = request.getParameter("code");
20 Customer c = s.findCustomer(username, code);
21 if(c==null){
22 response.getWriter().write("激活失败");
23 return;
24 }
25 c.setActived(true);
26 s.updateCustomer(c);
27 response.getWriter().write("<script type=‘text/javascript‘>alert(‘激活成功‘)</script>");
28 response.setHeader("Refresh", "0;URL="+request.getContextPath());
29 }
30 //注销
31 private void logout(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {
32 request.getSession().removeAttribute("customer");
33 response.sendRedirect(request.getContextPath());//重定向到主页
34 }
35 //登录
36 private void login(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {
37 String username = request.getParameter("username");
38 String password = request.getParameter("password");
39 Customer c = s.login(username, password);
40 if(c==null){
41 response.getWriter().write("<script type=‘text/javascript‘>alert(‘登录失败‘)</script>");
42 response.setHeader("Refresh", "0;URL="+request.getContextPath()+"/login.jsp");
43 return;
44 }
45 request.getSession().setAttribute("customer", c);
46 response.sendRedirect(request.getContextPath());//重定向到主页
47 }
48 private void regist(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {
49 Customer c = WebUtil.fillBean(request, Customer.class);
50 //生成随机验证码
51 String code = UUID.randomUUID().toString();
52 c.setCode(code);
53 //单独启动一个线程：发送激活邮件
54 SendMail sm = new SendMail(c);
55 sm.start();
56 s.regist(c);
57 response.getWriter().write("<script type=‘text/javascript‘>alert(‘注册成功！我们已经发送了一封激活邮件到您的邮箱，请注意查查‘)</script>");
58 response.setHeader("Refresh", "0;URL="+request.getContextPath());
59 }
60 public void doPost(HttpServletRequest request, HttpServletResponse response)
61 throws ServletException, IOException {
62 doGet(request, response);
63 }
64
65 }
ControllerServlet
四：实体类DAO层：
1 import org.apache.commons.dbutils.QueryRunner;
2 import org.apache.commons.dbutils.handlers.BeanHandler;
3
4 import com.itheima.dao.CustomerDao;
5 import com.itheima.domain.Customer;
6 import com.itheima.util.DBCPUtil;
7
8 public class CustomerDaoMySQLImpl implements CustomerDao {
9 private QueryRunner qr = new QueryRunner(DBCPUtil.getDataSource());
10 public void save(Customer c) {
11 try{
12 qr.update("insert into customer (id,username,password,phone,address,email,actived,code) values(?,?,?,?,?,?,?,?)",
13 c.getId(),c.getUsername(),c.getPassword(),
14 c.getPhone(),c.getAddress(),c.getEmail(),
15 c.isActived(),c.getCode());
16 }catch(Exception e){
17 throw new RuntimeException(e);
18 }
19 }
20
21 public Customer find(String username, String password) {
22 try{
23 return qr.query("select * from customer where username=? and password=?", new BeanHandler<Customer>(Customer.class), username,password);
24 }catch(Exception e){
25 throw new RuntimeException(e);
26 }
27 }
28
29 public Customer findByCode(String username, String code) {
30 try{
31 return qr.query("select * from customer where username=? and code=?", new BeanHandler<Customer>(Customer.class), username,code);
32 }catch(Exception e){
33 throw new RuntimeException(e);
34 }
35 }
36
37 public Customer findById(String customerId) {
38 try{
39 return qr.query("select * from customer where id=?", new BeanHandler<Customer>(Customer.class), customerId);
40 }catch(Exception e){
41 throw new RuntimeException(e);
42 }
43 }
44
45 public void update(Customer c) {
46 try{
47 qr.update("update customer set username=?,password=?,phone=?,address=?,email=?,actived=?,code=? where id=?",
48 c.getUsername(),c.getPassword(),
49 c.getPhone(),c.getAddress(),c.getEmail(),
50 c.isActived(),c.getCode(),c.getId());
51 }catch(Exception e){
52 throw new RuntimeException(e);
53 }
54 }
55
56 }
CustomerDaoMySQLImpl
