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=faw124awfawfawg
spring.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
@Slf4j
public 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)
@SpringBootTest
public 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。
