Springboot邮件发送 Springboot实现邮件发送功能

需求：用户注册账号绑定邮箱之后，下次登录时忘记密码，需要通过邮箱找回密码

1.创建springboot项目

2.pom导入依赖

<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//发件人邮箱，需要开启smtp服务
spring.mail.password=ming438434//授权密码，非邮箱的登录密码
spring.mail.port=25
spring.mail.protocol=smtp
spring.mail.default-encoding=UTF-8

发件人邮箱的设置：

邮箱客户端授权码也需要手动开启，设置授权码

4.用户输入自己的邮箱，点击找回，前端页面

html代码：

<div class="regWrap">
 <div class="regName">
 <span>请输入邮箱</span>
 <input id="mail" type="email" class="mail" placeholder="请输入邮箱">
 </div>
 <button id="registbtn" class="regBtn" type="button">找回</button>
</div>

js代码：

$(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("已发送至您的邮箱")
 location.href="/login.html" rel="external nofollow" ;
 }
 if (data=="failful") {
 alert("邮箱错误")
 }
 },
 error: function (data) { 
  alert("网络繁忙")
 } 
 });
 
 });
});

5.点击找回，进入controller层

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

service层

@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("亲爱的用户"+user2.getAccount()+",您的当前密码是："+user2.getPassword());
 stringBuilder.append("</br><a href='https://www.baidu.com/'>访问百度</a></body><html>");
 MimeMessage mimeMessage=javaMailSender.createMimeMessage();
 //multipart模式
 try {
 MimeMessageHelper mimeMessageHelper=new MimeMessageHelper(mimeMessage, true);
 mimeMessageHelper.setTo(user.getMail());//收件人邮箱user.getMail()
 mimeMessageHelper.setFrom("sple_vip@163.com");//发件人邮箱
 mimeMessage.setSubject("找回密码");
 //启用html
 mimeMessageHelper.setText(stringBuilder.toString(),true);
 javaMailSender.send(mimeMessage);
 return Constent.SUCCESSFUL;
 } catch (MessagingException e) {
 e.printStackTrace();
 return Constent.FAILFUL;
 }
 }
 
 /**
 * 通过邮箱到数据库查询用户的信息
 */
 @Override
 public User mailPwd(User user) {
 return userMapper.mailPwd(user);
 }
 
}

dao层

public interface UserMapper {
 /**
 * 通过邮箱查询用户信息
 */
 @Select("SELECT * FROM user WHERE mail = #{mail}")
 public User mailPwd(User user);
}

发送成功效果

这是一个简单的通过邮箱找回密码就完成了。
