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。
