springboot实现邮箱验证码功能

本文实例为大家分享了springboot实现邮箱验证码功能的具体代码，供大家参考，具体内容如下

我这边使用的QQ邮箱

1、首先创建maven项目，配置pom文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

 <properties>

 <directory>src/main/java</directory>
  <includes>
  <include>**/*.xml</include>
  </includes>
 </resource>
 </resources>
 </build>
 
</project>

2、配置springboot，我这里使用的是properties方式

#配置Mybatis别名和扫描包
mybatis.type-aliases-package=com.demo.bean
mybatis.mapper-locations=classpath:mapper/*.xml
 
#数据库相关
spring.datasource.url=jdbc:mysql://localhost:3306/ssm?useSSL=false
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
 
#配置日志
logging.level.root=info
logging.level.com.demo.mapper=debug
 
#配置视图前缀和后缀
spring.mvc.view.prefix=/
spring.mvc.view.suffix=.html
 
#邮件发送配置
spring.mail.default-encoding=UTF-8
spring.mail.host=smtp.qq.com
spring.mail.username=你的邮箱
spring.mail.password=邮箱授权码
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
 
#thymeleaf配置
spring.thymeleaf.mode=HTML5
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.servlet.content-type=text/html
spring.thymeleaf.cache=false

邮箱授权码可以按以下方法获取
打开QQ邮箱网页→设置→账户→POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服务→开启POP3/SMTP服务，然后就能看到授权码了

3、编写mailService

${spring.mail.username}是在properties中配置的属性，这里有一个方法，第一个是发送普通邮件，第二个是发送带有附件的邮件

@Service("mailService")
public class MailService {
 @Value("${spring.mail.username}")
 private String from;
 @Autowired
 private JavaMailSender mailSender;
 
 Logger logger = LoggerFactory.getLogger(this.getClass());
 
 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");
 }
 
 public void sendAttachmentsMail(String to, String title, String cotent, 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(cotent);
   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");
 }
}

4、编写controller

@Controller
public class MailController {
 @Autowired
 private MailService 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;
 }
}

5、编写页面

<!DOCTYPE html>
<html lang="en">
<head>
 <meta charset="UTF-8">
 <title>注册</title>
 <link rel="stylesheet" href="layui/css/layui.css" rel="external nofollow" >
 <script src="layui/layui.js"></script>
</head>
<body style="width: 100%;height: 100%;">
 <div style="margin-top: 15%;">
  <div class="layui-main" style="width: 700px;">
   <h1 style="text-align: center">请输入注册信息</h1>
   <form class="layui-form layui-form-pane">
    <div class="layui-form-item">
     <label class="layui-form-label">邮箱：</label>
     <div class="layui-input-block">
      <input id="email" type="email" name="username" class="layui-input" lay-verify="required"/>
     </div>
    </div>
    <div class="layui-form-item">
     <label class="layui-form-label">密码：</label>
     <div class="layui-input-block">
      <input id="password" type="password" name="password" class="layui-input" lay-verify="required"/>
     </div>
    </div>
    <div class="layui-form-item">
     <label class="layui-form-label">邮箱验证码：</label>
     <div class="layui-input-block">
      <input id="checkCode" type="text" name="checkCode" class="layui-input" lay-verify="required"/>
      <button id="sendCheckCode" type="button" class="layui-btn layui-btn-normal">获取验证码</button>
     </div>
    </div>
    <div class="layui-form-item">
     <div class="layui-input-block">
      <button class="layui-btn" lay-submit lay-filter="register">确认</button>
     </div>
    </div>
   </form>
  </div>
 </div>
 <script>
  layui.use("form",function () {
   var form = layui.form;
   var $ = layui.$;
   
   form.on("submit(register)",function (data) {
    var inputCheckCode = $("#checkCode").val();
    if (inputCheckCode == checkCode){
     $.ajax({
      url:"/register",
      type:"POST",
      data:data.field,
      async:false,
      success:function (text) {
       if ("ok" == text){
        layer.alert("注册成功",function () {
         window.location.href = "index.html";
        });
       }else{
        layer.alert("注册失败");
       }
      }
     });
    } else{
     layer.msg("验证码输入错误");
    }
    return false;
   });
 
   //验证码
   var checkCode = "";
 
   $("#sendCheckCode").click(function () {
    var email = $("#email").val();
    if (email == null || email == ""){
     layer.msg("请输入邮箱！！！");
     return;
    }
    var index = layer.open({
     type:3,
     content:"邮件发送中..."
    });
 
    $.ajax({
     url:"/getCheckCode?email="+email,
     type:"get",
     success:function (text) {
      if (text != null && text != ""){
       layer.close(index);
       layer.msg("已发送");
       checkCode = text;
       countDown();
      } else{
       layer.alert("获取失败，请重新获取")
      }
     }
    });
   });
 
   var maxTime = 60;
   function countDown(){
    if (maxTime == 0){
     checkCode = "";
     $("#sendCheckCode").removeClass("layui-btn-disabled");
     $("#sendCheckCode").removeAttr("disabled")
     $("#sendCheckCode").html("获取验证码");
     maxTime = 60;
    }else{
     $("#sendCheckCode").attr("disabled","disabled");
     $("#sendCheckCode").addClass("layui-btn-disabled");
     form.render();
     $("#sendCheckCode").html(maxTime+"秒后重新获取");
     maxTime--;
     setTimeout(countDown,1000);
    }
   }
 
  });
 </script>
</body>
</html>
