For more details, please visit my blog: Springboot implements the function of sending email verification code in the applet
Springboot implements email verification for applets
1. Configuration items
- Configure pom files and introduce dependency on sending emails
Add in the pom file:
<!--邮件发送核心包-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
- Modify the configuration file application.yml, here take the QQ mailbox as an example
I use the yml method here, of course, you can also use the properties method to write
#邮件发送配置
spring:
mail:
default-encoding: UTF-8
host: smtp.qq.com
username: 你的邮箱
password: 邮箱授权码
properties:
mail:
smtp:
auth: true
starttls:
enable: true
required: true
The email authorization code can be obtained as follows:
Open the QQ mailbox page → Settings → Account → POP3 / IMAP / SMTP / Exchange / CardDAV / CalDAV service → turn on the POP3 / SMTP service, and then you can see the authorization code
[External chain image transfer failed. The source site may have an anti-theft chain mechanism. It is recommended to save the image and upload it directly (img-k05s3Fon-1578461968057) )]
Second, write mailService and mailServiceImpl
The mail service layer and the mail service interface implementation layer
$ {spring.mail.username} is a property configured in yml. There is a method here. The first is to send regular mail, and the second is to send mail with attachments.
- Mail Service Layer (IMailService)
public interface IMailService {
//发送普通邮件
void sendSimpleMail(String to,String title,String content);
//发送带有附件的邮件
void sendAttachmentsMail(String to, String title, String content, List<File> fileList);
}
- Mail service interface implementation layer (MailServiceImpl)
@Service
public class MailServiceImpl implements IMailService {
@Value("${spring.mail.username}")
private String from;
@Resource
private JavaMailSender mailSender;
Logger logger = LoggerFactory.getLogger(this.getClass());
//发送普通邮件
@Override
public void sendSimpleMail(String to, String title, String content) {
SimpleMailMessage message = new SimpleMailMessage();
message.setFrom(from);
message.setTo(to);
message.setSubject(title);
message.setText(content);
mailSender.send(message);
logger.info("邮件发送成功");
}
//发送带有附件的邮件
@Override
public void sendAttachmentsMail(String to, String title, String content, List<File> fileList) {
MimeMessage message = mailSender.createMimeMessage();
try {
MimeMessageHelper helper = new MimeMessageHelper(message,true);
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(title);
helper.setText(content);
String fileName = null;
for (File file:fileList) {
fileName = MimeUtility.encodeText(file.getName(), "GB2312", "B");
helper.addAttachment(fileName, file);
}
} catch (Exception e) {
e.printStackTrace();
}
mailSender.send(message);
logger.info("邮件发送成功");
}
}
Third, write the controller
E-mail control layer
//获取邮箱验证的验证码
@RequestMapping("/getCheckCode")
public JsonResult getCheckCode(HttpServletRequest request) {
//获取微信小程序get的参数值并打印
String userEmail = request.getParameter("userEmail");
user = userService.queryUserByUserEmail(userEmail);
if (null == user) {
return new JsonResult(JsonResponseStatus.EMPTY.getCode(), JsonResponseStatus.EMPTY.getMsg());
}else{
String checkCode = String.valueOf(new Random().nextInt(899999) + 100000);
String message = "您的注册验证码为："+checkCode;
try {
mailService.sendSimpleMail(userEmail, "注册验证码", message);
}catch (Exception e){
return new JsonResult(JsonResponseStatus.EMPTY.getCode(), JsonResponseStatus.EMPTY.getMsg());
}
return new JsonResult(JsonResponseStatus.SUCCESS.getCode(), JsonResponseStatus.SUCCESS.getMsg(),checkCode);
}
}
Attach the control layer code that can be used on the Web page:
@Controller
public class MailController {
@Resource
private IMailService mailService;
@RequestMapping("getCheckCode")
@ResponseBody
public String getCheckCode(String email){
String checkCode = String.valueOf(new Random().nextInt(899999) + 100000);
String message = "您的注册验证码为："+checkCode;
try {
mailService.sendSimpleMail(email, "注册验证码", message);
}catch (Exception e){
return "";
}
return checkCode;
}
}
Fourth, write a small program email verification page
<!--pages/getCheckCode/getCheckCode.wxml-->
<form bindsubmit="getCheckCode">
<view class="form-list">
<view class="form-item">
<view class="form-item-hd">邮箱</view>
<view class="form-item-bd">
<input type="email" name="userEmail" value="{{userEmail}}" placeholder="请输入邮箱" maxlength="25" />
</view>
</view>
</view>
<!--按钮-->
<button formType="submit" class="edit-btn">获取验证码</button>
</form>
<form bindsubmit="toPasswordReset">
<view class="form-list">
<view class="form-item">
<view class="form-item-hd">验证码</view>
<view class="form-item-bd">
<input type="text" name="checkCode" value="{{checkCode}}" placeholder="请输入验证码" maxlength="20" />
</view>
</view>
</view>
<button formType="submit" class="edit-btn">进行验证</button>
</form>
Five, test
