SpringBoot使用qq邮箱发送邮件

Posted 2021-01-16 小三毛

　　最近公司要做一个邮箱注册和重置密码的功能，因为之前就做过，但是不是Springboot项目，所以相对来说还是比较容易的，在这里记录一下。

　　

一、引用Maven依赖 这里使用spring自带的邮件jar包

       <!-- 邮件服务 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-mail</artifactId>
        </dependency>

 

二、yml配置

#邮箱配置
spring：
  mail:
    host: smtp.exmail.qq.com
    port: 465
    protocol: smtp
    username: ********  //你的邮箱账号
    password: ********  //你的登陆密码
    default-encoding: UTF-8
    properties:
      mail:
        smtp:
          auth: true
          starttls:
            enable: true
            required: true

 

三、创建EmailImpl类作为email组件

@Component
public class EmailImpl {

    private final Logger logger = LoggerFactory.getLogger(this.getClass());

    @Resource
    private RedisUtil redisUtil;


    @Value("${spring.mail.username}")
    public String from;
    @Value("${spring.mail.password}")
    public String password;// 登录密码
    @Value("${spring.mail.protocol}")
    public String protocol;// 协议
    @Value("${spring.mail.port}")
    public String port;// 端口
    @Value("${spring.mail.host}")
    public String host;// 服务器地址

    private String theme = "注册验证码";

    private String reset = "重置验证码";

    //初始化参数
    public Session initProperties() {
        Properties properties = new Properties();
        properties.setProperty("mail.transport.protocol", protocol);
        properties.setProperty("mail.smtp.host", host);
        properties.setProperty("mail.smtp.port", port);
        // 使用smtp身份验证
        properties.put("mail.smtp.auth", "true");
        // 使用SSL,企业邮箱必需 start
        // 开启安全协议
        MailSSLSocketFactory mailSSLSocketFactory = null;
        try {
            mailSSLSocketFactory = new MailSSLSocketFactory();
            mailSSLSocketFactory.setTrustAllHosts(true);
        } catch (GeneralSecurityException e) {
            e.printStackTrace();
        }
        properties.put("mail.smtp.enable", "true");
        properties.put("mail.smtp.ssl.socketFactory", mailSSLSocketFactory);
        properties.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
        properties.put("mail.smtp.socketFactory.fallback", "false");
        properties.put("mail.smtp.socketFactory.port", port);
        Session session = Session.getDefaultInstance(properties, new Authenticator() {
            @Override
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(from, password);
            }
        });
        // 使用SSL,企业邮箱必需 end
        // TODO 显示debug信息 正式环境注释掉
        session.setDebug(true);
        return session;
    }

    /**
     * 发送注册邮箱验证码
     * @param sender
     * @return
     */
    public Boolean sendhtmlEmail(String sender) {
        boolean lean = false;
        try {
            Session session = initProperties();
            MimeMessage mimeMessage = new MimeMessage(session);
            mimeMessage.setFrom(new InternetAddress(from,"Tesra"));// 发件人,可以设置发件人的别名
            // 收件人,多人接收
            InternetAddress[] internetAddressTo = new InternetAddress().parse(sender);
            mimeMessage.setRecipients(Message.RecipientType.TO, internetAddressTo);
            // 主题
            mimeMessage.setSubject(theme);
            // 时间
            mimeMessage.setSentDate(new Date());
            // 容器类 附件
            MimeMultipart mimeMultipart = new MimeMultipart();
            // 可以包装文本,图片,附件
            MimeBodyPart bodyPart = new MimeBodyPart();
            String code = CodeUtils.getMathVal();
            // 设置内容 getEmailHtml是邮箱内容模板
            bodyPart.setContent(getEmailHtml(sender,code), "text/html; charset=UTF-8");
            mimeMultipart.addBodyPart(bodyPart);
            // 添加图片&附件
//            bodyPart = new MimeBodyPart();
//            bodyPart.attachFile(fileSrc);
//            mimeMultipart.addBodyPart(bodyPart);
            mimeMessage.setContent(mimeMultipart);
            mimeMessage.saveChanges();
            Transport.send(mimeMessage);
            redisUtil.set(sender,code, UserConstant.time);
            lean = true;
        } catch (MessagingException e) {
            e.printStackTrace();
            lean = false;
            logger.error("发送注册邮件失败："+sender+" ----"+e.getMessage());
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
            lean = false;
            logger.error("发送注册邮件失败："+sender+" ----"+e.getMessage());
        }
        return lean;
    }


    /**
     * 发送重置邮箱验证码
     * @param sender
     * @return
     */
    public Boolean sendHtmlEmailCZ(String sender) {
        Boolean lean = false;
        try {
            Session session = initProperties();
            MimeMessage mimeMessage = new MimeMessage(session);
            mimeMessage.setFrom(new InternetAddress(from,"Tesra"));// 发件人,可以设置发件人的别名
            // 收件人,多人接收
            InternetAddress[] internetAddressTo = new InternetAddress().parse(sender);
            mimeMessage.setRecipients(Message.RecipientType.TO, internetAddressTo);
            // 主题
            mimeMessage.setSubject(reset);
            // 时间
            mimeMessage.setSentDate(new Date());
            // 容器类 附件
            MimeMultipart mimeMultipart = new MimeMultipart();
            // 可以包装文本,图片,附件
            MimeBodyPart bodyPart = new MimeBodyPart();
            String code = CodeUtils.getMathVal();
            // 设置内容 getEmailReset是发送邮箱的html模板
            bodyPart.setContent(getEmailReset(sender,code), "text/html; charset=UTF-8");
            mimeMultipart.addBodyPart(bodyPart);
            // 添加图片&附件
//            bodyPart = new MimeBodyPart();
//            bodyPart.attachFile(fileSrc);
//            mimeMultipart.addBodyPart(bodyPart);
            mimeMessage.setContent(mimeMultipart);
            mimeMessage.saveChanges();
            Transport.send(mimeMessage);
            redisUtil.set(sender,code, UserConstant.time);
            lean = true;
        } catch (MessagingException e) {
            e.printStackTrace();
            lean = false;
            logger.error("发送重置邮件失败："+sender+" ----"+e.getMessage());
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
            lean = false;
            logger.error("发送重置邮件失败："+sender+" ----"+e.getMessage());
        }
        return lean;
    }
}

 

四、邮箱html模板

 

/**
     * 注册邮箱模板
     * @param to 邮箱号
     * @param code 验证码
     * @return
     */
    public String getEmailHtml(String to,String code){
        String[] tos = to.split("@");
        String sub = tos[0].substring(0,2);
        String email = sub+"*******@"+tos[1];
        String html = "<div style="padding: 0px 0px 0px 20px;box-sizing: border-box;color: #333333;font-family: "microsoft yahei";font-size: 14px">" +
               "<h3 style="font-weight: normal;font-size: 18px;">Test测试</h3>" +
               "<h4 style="color:#2672EC;font-size: 40px;margin-top: 24px;font-weight: normal;">账号注册验证码</h4>" +
               "<div style="margin-top: 40px;">您好，您正在使用<a href="javascript:;" target="_blank" style="color: #2672EC;text-decoration: none;">"+email+"</a>注册账号。</div>" +
               "<div style="margin-top: 30px;">您的注册验证码为：<em style="font-style: normal;font-weight: 600;">"+code+"</em></div>" +
               "<div style="margin-top: 35px;">谢谢！</div>" +
               "<div style="margin-top: 10px;">Test测试</div>" +
               "</div>";
        return html;
    }

 

 

五、方法调用

    @Autowired
    private EmailImpl emailImpl;

    //email邮箱号    
    emailImpl.sendHtmlEmail(email);

 

至此就完成了SpringBoot使用qq邮箱发送邮件。
