Email registration / Password back / authentication
principle
Set two fields in the database ,status:（0: not active ,1： Activation successful ）,activition_code:( Release activation code )：
The user fills in the information , Click registration , Insert data succeeded ,state The default field is 0, Generate a activition_code（ Use the e-mail you sent me 、 password 、 And the current time ） Also stored in the database .
Send E-mail , Prompt the user to log in to the mailbox to activate , There is an activation success page in the email URL,URL There are two parameters （ user ID And activation code ）.
The user logs in to the mailbox and clicks the link , Go to the process activated business logic page or Servlet, obtain URL Two parameters in , Query the data in the database based on these two parameters , If there is , Check whether the activation code transmitted from the link is consistent with the database field activation code , atypism , Delete this record in the database , And jump to the activation failure interface , Agreement , The field state by 1, Activation successful , Go to the activation success page .

Insert email address information

StringUtil.java
Preliminary verification of mailbox format
// Judge whether it is a mailbox
public static boolean isEmail(String str) {
String checkEmail = "^[\\w-]+(\\.[\\w-]+)*@[\\w-]+(\\.[\\w-]+)+$";
if (!isEmpty(str)) {
return str.matches(checkEmail);
} else {
return false;
}
}
UserService.java- Interface
User findUserByEmail(String email);// Get the mailbox back
void sendCheckCode(String email) throws BussinessException;// Send verification code
void modifyPassword(String email, String password, String checkcode) throws BussinessException;// Change Password
UserServiceImpl.java- Interface implementation logic
Send activation email
// Send activation email
String subject = " Student information resource sharing system system notification email ";
StringBuffer content = new StringBuffer(" dear 【" + user.getUserName() + "】 user <br><br>");
content.append(" Welcome to the student information resource sharing system ！<br><br>");
content.append(" Click on <a href='" + mailConfig.getGlob_Real_Path() + "/user/activate?userName=" + user.getUserName() +
"&activationCode=" + activationCode + "'> Student information resource sharing system account activation </a> Activate your account ！");

subject, new String(content));
} catch (Exception e) {
throw new BussinessException(" Failed to send email , Please try again later ");
}
design sketch 
Search for users by user name , Verify whether activation and registration are successful
public void updateUserActivate(String userName, String activationCode) throws BussinessException {
// Search for users by user name
User user = findUserByUserName(userName);
if (user == null) {
throw new BussinessException(" user 【"+userName+"】 non-existent , Please register the user ");
}
if (user.getUserPage() != 0) {
throw new BussinessException(" user 【"+userName+"】 Activated , Please log in ");
}
if (!activationCode.equals(user.getActivationCode())) {
throw new BussinessException(" user 【"+userName+"】 The activation code is invalid , Please use the latest activation link ");
}
userMapper.updateStatus(userName, activationCode);
}
status by 0 Represents that the account is not activated
if (user.getStatus() == 0) {
throw new BussinessException(" Please check your email , Log in after activating the account ");
}
Email verification code sent
public void sendCheckCode(String email) throws BussinessException {
if (StringUtil.isEmpty(email) || !StringUtil.isEmail(email)) {
throw new BussinessException(" Illegal input parameter ");
}
User user = findUserByEmail(email);
if (user == null) {
throw new BussinessException(" The mailbox doesn't exist ");
}
String checkCode = StringUtil.getActivationCode(6);
String subject = " Student information resource sharing system system notification email ";
StringBuffer content = new StringBuffer(" dear 【" + user.getUserName() + "】 user <br><br>");
content.append(" Welcome to <a href='"+mailConfig.getGlob_Real_Path()+"'> Student information resource sharing system </a> Password retrieval function of <br><br>");
content.append(" Your verification code is <h3 style='color:red;'>" + checkCode + "</h3>");
try {
System.out.println("======================"+checkCode);
MailUtil.sendMail(mailConfig.getSendUserName(), mailConfig.getSendPassword(), email,
subject, new String(content));
} catch (Exception e) {
throw new BussinessException(" Failed to send email , Please try again later ");
}
user.setActivationCode(checkCode);
userMapper.update(user);
}
User validation
@Transactional(propagation = Propagation.REQUIRES_NEW)
public Integer changeMark(String userid, int mark) {
return userMapper.changeUserMark(mark, userid);
}
public User findUserInfo4UserHome(String userId) throws BussinessException {
User user = findUserByUserid(userId);
if (user == null) {
throw new BussinessException(" The user doesn't exist ");
}
// Set password to blank
user.setPassword(null);
// Set the activation code to null
user.setActivationCode(null);
return user;
}
application-config Set the sender's mailbox
mail.sendUserName= Your email address （ recommend 163）
mail.sendPassword= mailbox pop Server address
