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
<!-- email --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-mail</artifactId> </dependency>
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 = "1876419736@qq.com"; // 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( "<!DOCTYPE html>\n" + "<html lang=\"en\">\n" + "<head>\n" + " <meta charset=\"UTF-8\">\n" + " <title>Title</title>\n" + "</head>\n" + "<body>\n" + "<h2>" + info + "</h2>\n" + "<h3>您的验证码为:<span style='color: red'" + ">" + emailModel.getEmailContent() + "</span> " + ",请在 5 分钟内进行验证</h3>\n" + "</body>\n" + "</html>" , 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"); }
