SpringBoot集成E-mail发送各种类型邮件

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
[email protected]
#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
[email protected]

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("[email protected]", "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("[email protected]","test simple mail"," hello this is simple mail");
 }

 @Test
 public void sendHtmlMailTest(){
  String content="\n" +
    "\n" +
    " 
hello world ! 这是一封Html邮件!
\n" +
    "\n" +
    "";
  mailService.sendHtmlMail("[email protected]","test html mail",content);
 }

 @Test
 public void sendAttachmentsMail(){
  String filePath="E:\\var\\log\\elkTest\\error\\2018-11-30.log";
  mailService.sendAttachmentsMail("[email protected]", "主题：带附件的邮件", "有附件，请查收！", filePath);
 }

 @Test
 public void sendInlineResourceMail() {
  String rscId = "neo006";
  String content="这是有图片的邮件：";
  String imgPath = "C:\\Users\\Admin\\Pictures\\Camera Roll\\9499189867_1476052069.jpg";

  mailService.sendInlineResourceMail("[email protected]", "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("[email protected]","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。
