Java SSH框架登陸註冊模塊
----------------------------------------------------寫在前面------------------------------------------------------- css
做爲一名小小程序猿，已經工做一年多了，因爲平時不用功學習，致使技術上積累太單薄。2015年即將結束，忽然發現本身這一年來進不如此至少，內心有點發慌。因而想改頭換面，重新學習。 html
Java Web知識點多，想要系統的學習須要多作一些實戰項目。因而我決定經過寫一個個咱們經常使用的模塊來系統的學習Java web相關技術。首先決定從登錄註冊模塊開始，由於這是咱們平時最經常使用的一個模塊。 java
時間有限，我就不一一講解項目從頭至尾是如何建立的，這篇文章也是給有必定基礎的Java開發人員看的。因爲技術有限，不免會有不少疏忽，若是你們發現有什麼不對的地方，歡迎指正！謝謝！ mysql
------------------------------------------------------------正文--------------------------------------------------- jquery
一. MYSQL數據庫建立
(我是用MySQL workbench建立的表，沒用SQL語句。表的數據結構以下圖) git
主要有留個字段： username用戶名，password密碼，email郵箱，status激活狀態，validateCode激活碼，signupTime註冊時間。 github
2. RegisterAction註冊
（這裏我就只貼出execute方法裏面的代碼，所有代碼請見github，github地址我會在博文最後貼出） web
private String signupUsername;
private String signupPassword;
private String signupEmail;
private int status;
private String validateCode;
private Date signupTime;
private UserService userService;
@Override
public String execute() throws Exception {
ActionContext context = ActionContext.getContext();
ValueStack stack = context.getValueStack();
signupUsername = (String) stack.findValue("signupUsername");
signupPassword = (String) stack.findValue("signupPassword");
signupPassword = MD5Util.encode2hex(signupPassword);
signupEmail = (String) stack.findValue("signupEmail");
User existingUser = this.userService.find(signupEmail);
if (existingUser != null) {
return ERROR;
} else {
signupTime = new Date();
status=0;
validateCode = MD5Util.encode2hex(signupEmail);
User user = new User(signupUsername,signupPassword,signupEmail,status,validateCode,signupTime);
userService.save(user);
StringBuffer sb=new StringBuffer("Please active your account within 48 hours!");
sb.append("<br/>");
sb.append("<a href = \"http://localhost:8080/RegistrationAndLoginExample/activeAccount?signupEmail=");
sb.append(signupEmail);
sb.append("&validateCode=");
sb.append(user.getValidateCode());
sb.append("\">Click here to activate your account!</a>");
SendEmail.send(signupEmail, sb.toString());
return SUCCESS;
}
}
3. 發郵件
public class SendEmail {
public static final String HOST = "smtp.163.com";
public static final String PROTOCOL = "smtp";
public static final int PORT = 25;
public static final String FROM = "請填寫你的郵箱";
public static final String PWD = "請填寫你郵箱密碼";
private static Session getSession() {
Properties props = new Properties();
props.put("mail.smtp.host", HOST);
props.put("mail.store.protocol" , PROTOCOL);
props.put("mail.smtp.port", PORT);
props.put("mail.smtp.auth" , true);
Authenticator authenticator = new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(FROM, PWD);
}
};
Session session = Session.getInstance(props , authenticator);
return session;
}
public static void send(String toEmail , String content) {
Session session = getSession();
try {
System.out.println("--send--"+content);
Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(FROM));
InternetAddress[] address = {new InternetAddress(toEmail)};
msg.setRecipients(Message.RecipientType.TO, address);
msg.setSubject("Account Activation");
msg.setSentDate(new Date());
msg.setContent(content , "text/html;charset=utf-8");
Transport.send(msg);
}
catch (MessagingException mex) {
mex.printStackTrace();
}
}
}
4. MD5加密
public class MD5Util {
public static byte[] encode2bytes(String source) {
byte[] result = null;
try {
MessageDigest md = MessageDigest.getInstance("MD5");
md.reset();
md.update(source.getBytes("UTF-8"));
result = md.digest();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
return result;
}
public static String encode2hex(String source) {
byte[] data = encode2bytes(source);
StringBuffer hexString = new StringBuffer();
for (int i = 0; i < data.length; i++) {
String hex = Integer.toHexString(0xff & data[i]);
if (hex.length() == 1) {
hexString.append('0');
}
hexString.append(hex);
}
return hexString.toString();
}
public static boolean validate(String unknown , String okHex) {
return okHex.equals(encode2hex(unknown));
}
}
5. ActiveAccountAction激活帳戶
private static final long serialVersionUID = 1L;
private String signupEmail;
private String validateCode;
private UserService userService;
@Override
public String execute() throws Exception {
ActionContext context = ActionContext.getContext();
ValueStack stack = context.getValueStack();
String signupEmail = (String) stack.findValue("signupEmail");
String validateCode = (String) stack.findValue("validateCode");
User user = this.userService.find(signupEmail);
if(user!=null) {
if(user.getStatus()==0) {
Date currentTime = new Date();
currentTime.before(user.getSignupTime());
if(currentTime.before(user.getLastActivateTime())) {
if(validateCode.equals(user.getValidateCode())) {
//update status to 1
user.setStatus(1);
this.userService.modify(user);
} else {
throw new ServiceException("validate code is not correct!");
}
} else { throw new ServiceException("validate code has been expired!");
}
} else {
throw new ServiceException("email has been activated!");
}
} else {
throw new ServiceException("this email has not been registered!");
}
return SUCCESS;
}
6. LoginAction登陸
private String email;
private String password;
private UserService userService;
@Override
public String execute() throws Exception {
ActionContext context = ActionContext.getContext();
ValueStack stack = context.getValueStack();
String email = (String) stack.findValue("email");
String password = (String) stack.findValue("password");
password = MD5Util.encode2hex(password);
if (email != null && email.length() > 0) {
if (password != null && password.length() > 0) {
if (this.userService == null) {
return ERROR;
}
User user = this.userService.find(email);
if (user != null) {
if(user.getStatus()==0){
return ERROR;
}else if (user.getPassword().equals(password)) {
HttpServletRequest request = ServletActionContext.getRequest();
HttpSession session = request.getSession();
session.setAttribute("user", user);
return SUCCESS;
}
}
}
}
return ERROR;
}
7. index.jsp 登陸，註冊等頁面

這裏引用了bootstrap， 和JQury, 同時用到了Ajax去實時查詢用戶所填寫的郵箱是否已經註冊過。 ajax
8. ForgotPasswordAction 忘記密碼
private String forgotPasswordEmail;
private UserService userService;
public String execute() throws Exception {
ActionContext context = ActionContext.getContext();
ValueStack stack = context.getValueStack();
forgotPasswordEmail = (String) stack.findValue("forgotPasswordEmail");
User existingUser = this.userService.find(forgotPasswordEmail);
if (existingUser == null) {
return ERROR;
} else {
Long validateCode = System.currentTimeMillis()+30*60*1000;
StringBuffer sb=new StringBuffer("Please reset your password within 30 mins!");
sb.append("<br/>");
sb.append("<a href = \"http://localhost:8080/RegistrationAndLoginExample/resetPassword?email=");
sb.append(forgotPasswordEmail);
sb.append("&validateCode=");
sb.append(validateCode);
sb.append("\">Click here to reset your password!</a>");
SendEmail.send(forgotPasswordEmail, sb.toString());
return SUCCESS;
}
}
當用戶請求忘記密碼時，發一封郵件到用戶郵箱， 要求用戶30分鐘內完成修改密碼。不然這次請求過時。 spring
9. ResetPasswordAction重置密碼
private String email;
private String validateCode;
private UserService userService;
@Override
public String execute() throws Exception {
ActionContext context = ActionContext.getContext();
ValueStack stack = context.getValueStack();
String email = (String) stack.findValue("email");
String validateCode = (String) stack.findValue("validateCode");
User user = this.userService.find(email);
if(user!=null) {
if(user.getStatus()!=0) {
Long currentTime = System.currentTimeMillis();
if(currentTime<Long.parseLong(validateCode)) {
return SUCCESS;
} else {
return ERROR;
}
} else {
throw new ServiceException("email has not been activated!");
}
} else {
throw new ServiceException("this email has not been registered!");
}
}
10. UpdatePasswordAction更新密碼
private String email;
private String oldPassword;
private String newPassword;
private UserService userService;
@Override
public String execute() throws Exception {
ActionContext context = ActionContext.getContext();
ValueStack stack = context.getValueStack();
String email = (String) stack.findValue("email");
String oldPassword = (String) stack.findValue("oldPassword");
String newPassword = (String) stack.findValue("newPassword");
User user = this.userService.find(email);
if(user!=null) {
if(user.getStatus()==1) {
if(user.getPassword().equals(MD5Util.encode2hex(oldPassword))){
user.setPassword(MD5Util.encode2hex(newPassword));
this.userService.modify(user);
} else {
throw new ServiceException("Old password is not correct!");
}
} else {
throw new ServiceException("email has not been activated!");
}
} else {
throw new ServiceException("this email has not been registered!");
}
return SUCCESS;
}
