SpringBoot继承JavaEmail发送邮箱验证码

1.导入pom依赖

        <!--引入邮箱插件-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-mail</artifactId>
            <version>2.1.1.RELEASE</version>
        </dependency>

2.编写邮箱模板实体类

@Data
@AllArgsConstructor
@NoArgsConstructor
public class EmailModel {

    //邮件标题
    private String title;
    //邮件内容
    private String message;
    //邮件的收件人
    private String emailReciver;
    
}

3.配置发送邮件的信息

public class JavaEmail {
    //发件人邮箱
    private static final String EMAIL_SEND = "发件人邮箱";
    //邮箱授权码
    private static final String EMAIL_KEY = "邮箱授权码";


    public static void sendEmail(EmailModel emailModel) throws Exception {
        Properties prop = new Properties();
        prop.setProperty("mail.host", "smtp.qq.com");
//        设置QQ邮件服务器
        prop.setProperty("mail.transport.protocol", "smtp"); // 邮件发送协议
        prop.setProperty("mail.smtp.auth", "true"); // 需要验证用户名密码

        // 关于QQ邮箱，还要设置SSL加密，加上以下代码即可
        MailSSLSocketFactory msf = new MailSSLSocketFactory();
        msf.setTrustAllHosts(true);
        prop.put("mail.smtp.ssl.enable", "true");
        prop.put("mail.smtp.ssl.socketFactory", msf);

        //使用JavaMail发送邮件的5个步骤
        //创建定义整个应用程序所需的环境信息的 Session 对象
        Session session = Session.getDefaultInstance(prop, new Authenticator() {
            public PasswordAuthentication getPasswordAuthentication() {
                //发件人邮件用户名、授权码
                return new PasswordAuthentication(EMAIL_SEND, EMAIL_KEY);
            }
        });
        //开启Session的debug模式，这样就可以查看到程序发送Email的运行状态
        session.setDebug(true);

        //2、通过session得到transport对象
        Transport ts = session.getTransport();

        //3、使用邮箱的用户名和授权码连上邮件服务器
        ts.connect("smtp.qq.com", EMAIL_SEND, EMAIL_KEY);

        //4、创建邮件

        //创建邮件对象
        MimeMessage message = new MimeMessage(session);

        //指明邮件的发件人
        message.setFrom(new InternetAddress(EMAIL_SEND));

        //指明邮件的收件人，现在发件人和收件人是一样的，那就是自己给自己发
        message.setRecipient(Message.RecipientType.TO, new InternetAddress(emailModel.getEmailReciver()));

        //邮件的标题
        message.setSubject(emailModel.getTitle());

        //邮件的文本内容
        message.setContent(emailModel.getMessage(), "text/html;charset=UTF-8");

        //5、发送邮件
        ts.sendMessage(message, message.getAllRecipients());

        // re=ts
        ts.close();

    }
}

授权码在QQ邮箱首页中找

 

 4.发送邮件

@Test
    void sendEmail() {
        String strs[] = { "1", "2", "3", "4", "5", "6", "7", "8", "9", "0" };
        Random random = new Random();
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < 6; i++) {
            String str=strs[random.nextInt(strs.length)];
            sb.append(str);
        }
        EmailModel model=new EmailModel("我的JavaEmail测试", "您的验证码是："+sb,"630640999@qq.com");
        try {
            JavaEmail.sendEmail(model);
            System.out.println("发送成功！");
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

以上均为QQ邮箱，如使用163，126等邮箱，更换协议，在邮箱中找到相应的授权码即可。
