這篇文章主要為大家詳細(xì)介紹了Springboot實(shí)現(xiàn)郵件發(fā)送功能，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了Springboot實(shí)現(xiàn)郵件發(fā)送具體代碼，供大家參考，具體內(nèi)容如下

需求：用戶(hù)注冊(cè)賬號(hào)綁定郵箱之后，下次登錄時(shí)忘記密碼，需要通過(guò)郵箱找回密碼

1.創(chuàng)建springboot項(xiàng)目

2.pom導(dǎo)入依賴(lài)

<dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-mail</artifactId>
</dependency>

3.application.properties配置文件

spring.mail.host=smtp.163.com
spring.mail.username=sple_vip@163.com//發(fā)件人郵箱，需要開(kāi)啟smtp服務(wù)
spring.mail.password=ming438434//授權(quán)密碼，非郵箱的登錄密碼
spring.mail.port=25
spring.mail.protocol=smtp
spring.mail.default-encoding=UTF-8

發(fā)件人郵箱的設(shè)置：

郵箱客戶(hù)端授權(quán)碼也需要手動(dòng)開(kāi)啟，設(shè)置授權(quán)碼

4.用戶(hù)輸入自己的郵箱，點(diǎn)擊找回，前端頁(yè)面

html代碼：

<div class="regWrap">
 <div class="regName">
 <span>請(qǐng)輸入郵箱</span>
 <input id="mail" type="email" class="mail" placeholder="請(qǐng)輸入郵箱">
 </div>
 <button id="registbtn" class="regBtn" type="button">找回</button>
</div>

js代碼：

$(function () {
 $("#registbtn").click(function() {
 var user = {
 mail:$("#mail").val()
 }
 $.ajax({ 
 type: "POST", 
 url:"/mail.action",
 contentType: "application/json;",
 data: JSON.stringify(user),
 success: function (data) {
 if(data == "successful"){
 alert("已發(fā)送至您的郵箱")
 location.href="/login.html" rel="external nofollow" ;
 }
 if (data=="failful") {
 alert("郵箱錯(cuò)誤")
 }
 },
 error: function (data) { 
  alert("網(wǎng)絡(luò)繁忙")
 } 
 });
 
 });
});

5.點(diǎn)擊找回，進(jìn)入controller層

@RequestMapping("/mail.action")
public String mail(@RequestBody User user) {
 return mailService.sendMail(user);
}

service層

@Service
public class MailServiceImpl implements MailService{
 @Autowired
 private JavaMailSender javaMailSender;
 @Autowired
 private UserMapper userMapper;
 @Override
 public String sendMail(User user) {
 User user2 = mailPwd(user);
 StringBuilder stringBuilder=new StringBuilder();
 stringBuilder.append("<html><head><title></title></head><body>");
 stringBuilder.append("親愛(ài)的用戶(hù)"+user2.getAccount()+",您的當(dāng)前密碼是："+user2.getPassword());
 stringBuilder.append("</br><a );
 MimeMessage mimeMessage=javaMailSender.createMimeMessage();
 //multipart模式
 try {
 MimeMessageHelper mimeMessageHelper=new MimeMessageHelper(mimeMessage, true);
 mimeMessageHelper.setTo(user.getMail());//收件人郵箱user.getMail()
 mimeMessageHelper.setFrom("sple_vip@163.com");//發(fā)件人郵箱
 mimeMessage.setSubject("找回密碼");
 //啟用html
 mimeMessageHelper.setText(stringBuilder.toString(),true);
 javaMailSender.send(mimeMessage);
 return Constent.SUCCESSFUL;
 } catch (MessagingException e) {
 e.printStackTrace();
 return Constent.FAILFUL;
 }
 }
 
 /**
 * 通過(guò)郵箱到數(shù)據(jù)庫(kù)查詢(xún)用戶(hù)的信息
 */
 @Override
 public User mailPwd(User user) {
 return userMapper.mailPwd(user);
 }
 
}

dao層

public interface UserMapper {
 /**
 * 通過(guò)郵箱查詢(xún)用戶(hù)信息
 */
 @Select("SELECT * FROM user WHERE mail = #{mail}")
 public User mailPwd(User user);
}

發(fā)送成功效果
