SpringBoot集成E-mail发送各种类型邮件

时间：2021-05-20

SpringBoot 集成 E-mail发送邮件，供大家参考，具体内容如下

JDK本身有自带发送邮件api，加上SpringBoot在进行封装，使得现在使用起来十分快速简洁。
话不多说，参考纯洁的微笑博客，更改jar版本为2.0.4 开干，基本没什么坑。
就是配置邮箱账号密码是，如果是qq邮箱，需要开启PO30和STMP服务，并且获取临时授权码。

开启服务链接：

https://mail.qq.com/cgi-bin/frame_html?sid=a5ZSbreeNm9pHyl1&r=a83225170e94773c650a460c10f7a05c

与Springboot集成

导入jar包

compile group: 'org.springframework.boot', name: 'spring-boot-starter-mail', version: '2.0.4.RELEASE'compile 'org.springframework.boot:spring-boot-starter-thymeleaf:2.0.4.RELEASE'

配置邮箱

#邮箱服务器地址，各大运营商不同spring.mail.host=smtp.qq.com#用户名spring.mail.username=9118542413@qq.com#密码，如果是qq的，要申请临时授权码spring.mail.password=faw124awfawfawgspring.mail.default-encoding=UTF-8#以谁来发送邮件mail.fromMail.addr=9118542413@qq.com

发送各种类型的邮件

@Service@Slf4jpublic class MailServiceImpl implements MailService { @Autowired private JavaMailSender mailSender; /** * The Template engine. */ @Autowired TemplateEngine templateEngine; @Value("${mail.fromMail.addr}") private String from; @Override public void sendSimpleMail(String to, String subject, String content) { SimpleMailMessage message = new SimpleMailMessage(); message.setFrom(from); message.setTo(to); message.setSubject(subject); message.setText(content); try { mailSender.send(message); log.info("简单邮件已经发送。"); } catch (Exception e) { log.error("发送简单邮件时发生异常！", e); } } @Override public void sendHtmlMail(String to, String subject, String content) { MimeMessage message = mailSender.createMimeMessage(); try { //true表示需要创建一个multipart message MimeMessageHelper helper = new MimeMessageHelper(message, true); helper.setFrom(from); helper.setTo(to); helper.setSubject(subject); helper.setText(content, true); mailSender.send(message); log.info("html邮件发送成功"); } catch (MessagingException e) { log.error("发送html邮件时发生异常！", e); } } @Override public void sendAttachmentsMail(String to, String subject, String content, String filePath) { MimeMessage message = mailSender.createMimeMessage(); try { MimeMessageHelper helper = new MimeMessageHelper(message, true); helper.setFrom(from); helper.setTo(to); helper.setSubject(subject); helper.setText(content, true); FileSystemResource file = new FileSystemResource(new File(filePath)); String fileName = filePath.substring(filePath.lastIndexOf(File.separator) + 1); helper.addAttachment(fileName, file); mailSender.send(message); log.info("带附件的邮件已经发送。"); } catch (MessagingException e) { log.error("发送带附件的邮件时发生异常！", e); } } @Override public void sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId) { MimeMessage message = mailSender.createMimeMessage(); try { MimeMessageHelper helper = new MimeMessageHelper(message, true); helper.setFrom(from); helper.setTo(to); helper.setSubject(subject); helper.setText(content, true); FileSystemResource res = new FileSystemResource(new File(rscPath)); helper.addInline(rscId, res); mailSender.send(message); log.info("嵌入静态资源的邮件已经发送。"); } catch (MessagingException e) { log.error("发送嵌入静态资源的邮件时发生异常！", e); } } @Override public void sendTemplateMail(String to, String subject, String template, Context context) { String emailContent = templateEngine.process(template, context); sendHtmlMail("15017263512@163.com", "主题：这是模板邮件", emailContent); }}

测试类：

@RunWith(SpringRunner.class)@SpringBootTestpublic class EmailServiceTest { @Autowired MailService mailService; @Test public void sendSimpleMailTest() { mailService.sendSimpleMail("15017263512@163.com","test simple mail"," hello this is simple mail"); } @Test public void sendHtmlMailTest(){ String content="<html>\n" + "<body>\n" + " <h3>hello world ! 这是一封Html邮件!</h3>\n" + "</body>\n" + "</html>"; mailService.sendHtmlMail("15017263512@163.com","test html mail",content); } @Test public void sendAttachmentsMail(){ String filePath="E:\\var\\log\\elkTest\\error\\2018-11-30.log"; mailService.sendAttachmentsMail("15017263512@163.com", "主题：带附件的邮件", "有附件，请查收！", filePath); } @Test public void sendInlineResourceMail() { String rscId = "neo006"; String content="<html><body>这是有图片的邮件：<img src=\'cid:" + rscId + "\' ></body></html>"; String imgPath = "C:\\Users\\Admin\\Pictures\\Camera Roll\\9499189867_1476052069.jpg"; mailService.sendInlineResourceMail("15017263512@163.com", "主题：这是有图片的邮件", content, imgPath, rscId); } @Test public void sendTemplateMail() { //创建邮件正文 Context context = new Context(); context.setVariable("id", "006"); mailService.sendTemplateMail("15017263512@163.com","主题：这是模板邮件", "emailTemplate",context); }}

上面的邮箱和密码是我乱填的，注意自己更改。
