SpringBoot发送html邮箱验证码功能

SpringBoot发送html邮箱验证码功能

1. 效果展示(用户收到的)

2. 邮件推送管理（见以后的博客）

先看看如果管理员手动发送该如何操作

3. 后端核心代码（通用版）

3.1 SendEmailVO实体类

package com.example.han.model.VO;

import io.swagger.v3.oas.annotations.media.Schema;

import lombok.AllArgsConstructor;

import lombok.Data;

import lombok.NoArgsConstructor;

import java.util.Map;

@Data

@AllArgsConstructor

@NoArgsConstructor

@Schema(description = "发送邮件VO实体类")

public class SendEmailVO {

@Schema(description = "收件人邮箱")

String toAddress;

@Schema(description = "模板名")

String modelName;

@Schema(description = "邮件标题")

String title;

@Schema(description = "文本里所需要参数")

Map parameters;

@Schema(description = "调用者类型(管理员/服务)")

String manageType;

@Schema(description = "(调用者/服务)名称")

String manager;

}

3.2 Controller层核心代码

@Operation(summary = "发送html邮件")

@PutMapping("/sendemail")

public ResultReturn sendEmail(@RequestBody SendEmailVO sendEmailVO){

return (sendModelService.sendEmailByParam(sendEmailVO));

}

3.3 ServiceImpl层核心代码

@Autowired

HtmlEmailServiceImpl htmlEmailService;

/**

* 通过模板名查找html文本

* @param name 模板名

* @return 返回html文本

*/

public String getTextByName(String name){

List lists = mailRepository.getAllMailModel();

for (MailModelDO list : lists){

if(list.getModelName().equals(name)){

return list.getHtmlText();

}

}

return "NOT FOUND";

}

/**

* 发送邮件的操作

* @param sendEmailVO 发送邮件VO实体类

* @return 收件人邮箱

*/

public ResultReturn sendEmailByParam(SendEmailVO sendEmailVO){

String str = getTextByName(sendEmailVO.getModelName());

if(!CheckMail.checkMail(sendEmailVO.getToAddress())){

return ResultReturnUtil.fail(WRONG_EMAIL_ADDRESS);

}

if(sendEmailVO.getTitle().equals("")){

return ResultReturnUtil.fail(EMPTY_TITLE);

}

if(str.equals("NOT FOUND")){

return ResultReturnUtil.fail(FIND_MODEL_FAILED);

}

ReplaceWordUtil replaceWordUtil = new ReplaceWordUtil();

String content = replaceWordUtil.replaceWord(str,sendEmailVO.getParameters());

MailInfoTO info = new MailInfoTO();

info.setToAddress(sendEmailVO.getToAddress());

info.setSubject(sendEmailVO.getTitle());

info.setContent(content);

try {

htmlEmailService.sendHtmlMail(info);

} catch (Exception e) {

//System.out.print("'"+sendEmailVO.getTitle()+"'的邮件发送失败！");

e.printStackTrace();

}

MailHistoryDO mailHistoryDO = ToBeMailHistoryDO(sendEmailVO);

mailRepository.saveHistory(mailHistoryDO);

return ResultReturnUtil.success(SEND_EMAIL_SUCCESS,sendEmailVO.getToAddress());

}

3.4 利用正则检查邮箱是否合法工具类

package com.example.han.util;

import java.util.regex.Matcher;

import java.util.regex.Pattern;

public class CheckMail {

public static boolean checkMail(String mail){

Pattern pattern=Pattern.compile("\\w+([-+.]\\w+)*@\\w+([-.]\\w+)*\\.\\w+([-.]\\w+)*");

//\w+@(\w+.)+[a-z]{2,3}

Matcher matcher=pattern.matcher(mail);

return matcher.matches();

}

}

3.5 字符替换工具类

就是为了将模板中的花括号替换成真正需要的东西

package com.example.han.util;

import java.util.Iterator;

import java.util.Map;

/**

* 将str通过map的key转换成value

*/

public class ReplaceWordUtil {

public String replaceWord(String str, Map map) {

Iterator iter = http://map.entrySet().iterator();

while (iter.hasNext()) {

Map.Entry entry = (Map.Entry) iter.next();

Object key = entry.getKey();

Object value = entry.getValue();

str = str.replace("{{"+key+"}}",value+"");

//System.out.println(key+":"+value);

}

//System.out.println(str);

return str;

}

}

3.6 Reposity层 逻辑并不是很好，是找出来所有模版以后，开始遍历出来想要的那一个

package com.example.han.repository;

import com.example.han.model.DO.MailHistoryDO;

import com.example.han.model.DO.MailModelDO;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.data.mongodb.core.MongoTemplate;

import org.springframework.data.mongodb.core.query.Query;

import org.springframework.stereotype.Repository;

import java.util.List;

@Repository

public class MailRepository {

@Autowired

MongoTemplate mongoTemplate;

public List getAllMailModel(){

System.out.println(mongoTemplate.findAll(MailModelDO.class));

return mongoTemplate.findAll(MailModelDO.class);

}

}

3.7 发送html邮件的核心配置类

package com.example.han.service.impl;

import com.example.han.model.TO.MailInfoTO;

import org.springframework.beans.factory.annotation.Value;

import org.springframework.stereotype.Service;

import javax.mail.*;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeBodyPart;

import javax.mail.internet.MimeMessage;

import javax.mail.internet.MimeMultipart;

import java.util.Date;

import java.util.Properties;

@Service

public class HtmlEmailServiceImpl{

@Value("${spring.mail.host}")

private String host;

@Value("${spring.mail.username}")

private String formName;

@Value("${spring.mail.password}")

private String password;

@Value("${spring.mail.username}")

private String replayAddress;

/**

* 发送html邮件

* @param info MailInfo实体类

* @throws Exception 抛出异常

*/

public void sendHtmlMail(MailInfoTO info) throws Exception {

System.out.println(host);

System.out.println(formName);

info.setHost(host);

info.setFormName(formName);

info.setFormPassword(password); //网易邮箱的授权码~不一定是密码

info.setReplayAddress(replayAddress);

System.out.println(info.getHost());

System.out.println(info.getContent());

Message message = getMessage(info);

// MiniMultipart类是一个容器类，包含MimeBodyPart类型的对象

Multipart mainPart = new MimeMultipart();

// 创建一个包含HTML内容的MimeBodyPart

BodyPart html = new MimeBodyPart();

// 设置HTML内容

html.setContent(info.getContent(), "text/html; charset=utf-8");

mainPart.addBodyPart(html);

// 将MiniMultipart对象设置为邮件内容

message.setContent(mainPart);

Transport.send(message);

}

public Message getMessage(MailInfoTO info) throws Exception{

final Properties p = System.getProperties() ;

p.setProperty("mail.smtp.host", info.getHost());

p.setProperty("mail.smtp.auth", "true");

p.setProperty("mail.smtp.user", info.getFormName());

p.setProperty("mail.smtp.pass", info.getFormPassword());

// 根据邮件会话属性和密码验证器构造一个发送邮件的sessiqceXeEon

Session session = Session.getInstance(p, new Authenticator(){

protected PasswordAuthentication getPasswordAuthentication() {

return new PasswordAuthentication(p.getProperty("mail.smtp.user"),p.getProperty("mail.smtp.pass"));

}

});

session.setDebug(true);

Message message = new MimeMessage(session);

//消息发送的主题

message.setSubject(info.getSubject());

//接受消息的人

message.setReplyTo(InternetAddress.parse(info.getReplayAddress()));

//消息的发送者

message.setFrom(new InternetAddress(p.getProperty("mail.smtp.user"),"这是我的名字"));

// 创建邮件的接收者地址，并设置到邮件消息中

message.setRecipient(Message.RecipientType.TO,new InternetAddress(info.getToAddress()));

// 消息发送的时间

message.setSentDate(new Date());

return message ;

}

}

4. 后端代码（qceXeE带例子版）

4.1 Controller层

@Operation(summary = "设置并发送忘记密码的验证码")

@PostMapping("/sendForgetPasswordCode")

public ResultReturn sendForgetPasswordCode(String email) throws MyException {

return userService.sendForgetCode(email);

}

4.2 ServiceImpl层

这里我都配置到系统里去了，每次就不用管理员手动发送，只要用户发个请求，系统就能自动生成并发送验证码。

里面的工具类还有一些方法，可以查阅上面通用版里面的代码，这里我就不赘述了。

@Override

public ResultReturn sendForgetCode(String email) throws MyException {

if(!CheckMail.checkMail(email)){

throw new MyException(400,WRONG_EMAIL_ADDRESS);

}

String num = ""+RandomUtil.Code();

redisUtil.setRedisKey("forgetCode", num, 60*5); //先存入redis

SendEmailVO sendEmailVO = new SendEmailVO();

sendEmailVO.setManageType("System");

sendEmailVO.setManager("ForgetPasswordSystem");

sendEmailVO.setModelName("forgetCode"); //需要用的模版名字

Map map = new HashMap();

map.put("code",num);

sendEmailVO.setParameters(map);

sendEmailVO.setTitle("诗云-忘记密码-验证码");

sendEmailVO.setToAddress(email);

sendEmailService.sendEmailByParam(sendEmailVO);

return ResultReturnUtil.success(SEND_VERIFICATION_CODE_SUCCESS,email);

}

5. html邮件内容
