Those who have learned the basics of Java should know that there is an email in Java. If you are not familiar with it, you can simply review it.
This article regards sending emails as a configurable and configurable file, which is convenient for future maintenance
1. Maven dependency package (jar package that is dependent on sending emails)
<!--mail-->
<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.4</version>
</dependency>
<dependency>
<groupId>javax.activation</groupId>
<artifactId>activation</artifactId>
<version>1.1.1</version>
</dependency>
Second, set the configurable file
New .properties file
Configured as follows
##Enable debug debugging #mail.debug=true ## Sending server requires authentication mail.smtp.auth=true ##Set the mail server hostname mail.host=smtp.163.com ## Send mail protocol name mail.transport.protocol=smtp ##link address url=127.0.0.1:8089 ##Email account password mail.username=xxxx mail.password=xxxx
3. Send mail
@PostMapping("/updateResetPwd")
@ResponseBody
public JsonResult updateResetPwd(@RequestBody User input,HttpServletRequest request) throws IOException {
JsonResult result = new JsonResult();
String roleName = (String) request.getSession().getAttribute("roleName" );
if (!"Super Admin".equals(roleName) && "Super Admin" .equals(input.getRoleName())){
result.setMsg("supermana");
return result;
}
input.setPassword(PasswordUtils.passwordEncrypt("123456"));
User user = userService.selectById(input.getId());
Integer flag = userService.updateResetPassword(input);
try {
//Pass in the email to be sent, user id username
sendEmil(user.getEmail(),user.getId(),user.getTrueName());
} catch (MessagingException e) {
e.printStackTrace ();
}
if (1 == flag) {
result.setSuccess(true);
} else {
result.setSuccess(false);
}
return result;
}
/**
* Reset password to send email
* @throws MessagingException
*/
public void sendEmil(String Femail,String id,String userName) throws MessagingException, IOException {
Properties props = new Properties();
// Read configuration file
props.load( this .getClass().getResourceAsStream("/mailConfig.properties" ));
Session session = Session.getInstance(props);
// Create a mail object
Message msg = new MimeMessage(session);
try {
msg.setSubject( "Change password" );
} catch (MessagingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// set the email content
String msgContent = "Dear User" + userName + " Hello, <br/><br/>"
+ "You are" + new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format( new Date()) + "Submit a password reset request.<br/><br/>"
+ "Please open the following link to reset your password:<br/><br/>"
+ "<a href="+props.getProperty("url")+"/user/resetPwd?id="+id+">http://"+props.getProperty("url")+"/user/resetPwd?id="+id+"</a><br/><br/>"
+ "Thank you for using this system." + "<br/><br/>"
+ "This is an automatic email, please do not reply directly!" ;
msg.setContent(msgContent, "text/html;charset=utf-8"); // Set the email content, html format
// Set the sender
msg.setFrom( new InternetAddress(MimeUtility.encodeText("Modify password") + " <"+ props.getProperty("mail.username")+">")); // Set the mail source
Transport transport = session.getTransport();
// Connect the mail server
transport.connect(props.getProperty(" mail.username"), props.getProperty("mail.password" ));
// send mail
transport.sendMessage(msg, new Address[] { new InternetAddress(Femail)});
// close the connection
transport.close();
}
4. This example uses NetEase mailbox. To complete sending emails, you need to complete the last step. Open POP3 and take NetEase mailbox as an example.
