1. 准备工作

登录进自己的 qq 邮箱获取授权码

设置 – 账户 – POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服务

点击开始获取授权码，将授权码保存下来，下面代码整合的时候需要使用

2. 代码整合

创建一个 Spring Boot 项目，引入以下依赖

    org.springframework.boot
    spring-boot-starter-mail

配置文件

server:
  port: 8080
spring:
  # email 配置
  mail:
    # SMTP 服务器地址
    host: smtp.qq.com
    username: # 你的qq 邮箱地址
    password: # 授权码，上面从 qq 邮箱官网得到的授权码
    port: 587
    protocol: smtp
    default-encoding: UTF-8

创建一个邮件收件人信息的实体类

/**
 * @author lishisen
 * @description 邮件收件人信息
 * @date 2022/1/9 9:37
 **/
@AllArgsConstructor
@NoArgsConstructor
@Data
public class EmailModel implements Serializable {

    // 收件人邮箱地址
    private String receiveEmailAddress;
    // 邮箱主题
    private String emailTheme;
    // 邮件内容
    private String emailContent;

}

创建一个服务提供类，SendEmailService.java

/**
 * @author lishisen
 * @description 邮件发送服务类
 * @date 2022/1/9 9:40
 **/
@Slf4j
@Component
public class SendEmailService {

    @Autowired
    private JavaMailSender javaMailSender;
    @Autowired
    private JavaMailSenderImpl javaMailSenderImpl;

    // 发送者地址
    private String posterAddress = "[email protected]";
    // 发送者名称
    private String posterName = "测试邮件发送";

    /**
     * 文本发送
     **/
    public void sendEmailAsText(final EmailModel emailModel) {
        System.out.println(emailModel.toString());
        MimeMessagePreparator mimeMessagePreparator = mimeMessage -> {
            mimeMessage.setFrom(posterAddress);
            mimeMessage.setRecipients(Message.RecipientType.TO, emailModel.getReceiveEmailAddress());
            mimeMessage.setText("发送者地址：" + posterAddress + '\n'
                    + "发送者名称：" + posterName + '\n'
                    + "内容：" + emailModel.getEmailContent());
        };
        try {
            this.javaMailSender.send(mimeMessagePreparator);
            log.info("邮箱已返送至[{}]邮箱！", emailModel.getReceiveEmailAddress());
        } catch (MailException e) {
            log.error("邮箱异常：{}", e);
        }
    }

    /**
     * html 网页发送
     * 该方法为同步方法
     **/
    public void sendEmailAsSysExceptionHtml(final EmailModel emailModel, String info) {
        MimeMessage mimeMessage = javaMailSenderImpl.createMimeMessage();
        MimeMessageHelper mimeMessageHelper;
        try {
            mimeMessageHelper = new MimeMessageHelper(mimeMessage, true);
            mimeMessageHelper.setFrom(posterAddress);
            mimeMessageHelper.setTo(emailModel.getReceiveEmailAddress());
            mimeMessageHelper.setSubject(emailModel.getEmailTheme());
            mimeMessageHelper.setText(
                    "\n" +
                            "\n" +
                            "\n" +
                            "    \n" +
                            "    \n" +
                            "\n" +
                            "\n" +
                            "
" + info + "
\n" +
                            "
您的验证码为：" +
                            emailModel.getEmailContent() +
                            " " + "，请在 5 分钟内进行验证
\n" +
                            "\n" +
                            ""
                    , true);
            this.javaMailSender.send(mimeMessage);
            log.info("邮箱已返送至[{}]邮箱！", emailModel.getReceiveEmailAddress());
        } catch (MessagingException e) {
            e.printStackTrace();
        }
    }
}

测试使用

@Autowired
private SendEmailService sendEmailService;
@Test
public void sendMailTest() {
    // 创建收件人实体类，封装收件人的信息
    EmailModel emailModel = new EmailModel();
    emailModel.setReceiveEmailAddress("18xxxxxqq.com");
    emailModel.setEmailTheme("测试发送");
    emailModel.setEmailContent("测试发送邮箱主体信息内容");
    // 调用发送服务方法执行发送任务
    sendEmailService.sendEmailAsText(emailModel);
    System.out.println("邮件发送成功");
}
