Spring Boot 邮件发送

pom文件依赖

 <dependency>

             <groupId>org.springframework.boot</groupId>

             <artifactId>spring-boot-starter-mail</artifactId>

         </dependency>

pom.xml

配置文件

 spring:

   mail:

     host: smtp.qq.com                #协议 这边使用的QQ

     username: xxxxxxx@qq.com  #用户名

     password: xxxxxx                  #邮箱授权码

     default-encoding: UTF-8         #编码格式

创建Mail服务类

 public interface MailService {

     /**

      * 发送普通文本邮件

      * @param to 收件人

      * @param subject 主题

      * @param content 内容

      */

     void sendSimpleMail(String to, String subject, String content);

     /**

      * 发送HTML邮件

      * @param to 收件人

      * @param subject 主题

      * @param content 内容（可以包含<html>等标签）

      */

     void sendHtmlMail(String to, String subject, String content);

     /**

      * 发送带附件的邮件

      * @param to 收件人

      * @param subject 主题

      * @param content 内容

      * @param filePath 附件路径

      */

     void sendAttachmentMail(String to, String subject, String content, String filePath);

     /**

      * 发送带图片的邮件

      * @param to 收件人

      * @param subject 主题

      * @param content 文本

      * @param rscPath 图片路径

      * @param rscId 图片ID，用于在<img>标签中使用，从而显示图片

      */

     void sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId);

 }

MailService.java

 @Service

 public class MailServiceImpl implements MailService {

     private final Logger logger = LoggerFactory.getLogger(MailServiceImpl.class);

     @Value("${spring.mail.username}")

     private String from;

     @Autowired

     private JavaMailSender mailSender;

     @Override

     public void sendSimpleMail(String to, String subject, String content) {

         SimpleMailMessage message = new SimpleMailMessage();

         message.setTo(to);//收信人

         message.setSubject(subject);//主题

         message.setText(content);//内容

         message.setFrom(from);//发信人

         mailSender.send(message);

     }

     @Override

     public void sendHtmlMail(String to, String subject, String content) {

         logger.info("发送HTML邮件开始：{},{},{}", to, subject, content);

         MimeMessage message = mailSender.createMimeMessage();

         MimeMessageHelper helper;

         try {

             helper = new MimeMessageHelper(message, true);

             helper.setFrom(from);

             helper.setTo(to);

             helper.setSubject(subject);

             helper.setText(content, true);//true代表支持html

             mailSender.send(message);

             logger.info("发送HTML邮件成功");

         } catch (MessagingException e) {

             logger.error("发送HTML邮件失败：", e);

         }

     }

     @Override

     public void sendAttachmentMail(String to, String subject, String content, String filePath) {

         logger.info("发送带附件邮件开始：{},{},{},{}", to, subject, content, filePath);

         MimeMessage message = mailSender.createMimeMessage();

         MimeMessageHelper helper;

         try {

             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 = file.getFilename();

             helper.addAttachment(fileName, file);//添加附件，可多次调用该方法添加多个附件

             mailSender.send(message);

             logger.info("发送带附件邮件成功");

         } catch (MessagingException e) {

             logger.error("发送带附件邮件失败", e);

         }

     }

     @Override

     public void sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId) {

         logger.info("发送带图片邮件开始：{},{},{},{},{}", to, subject, content, rscPath, rscId);

         MimeMessage message = mailSender.createMimeMessage();

         MimeMessageHelper helper;

         try {

             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);//重复使用添加多个图片

             mailSender.send(message);

             logger.info("发送带图片邮件成功");

         } catch (MessagingException e) {

             logger.error("发送带图片邮件失败", e);

         }

     }

 }

MailServiceImpl.java

最后Test一波

 @RunWith(SpringRunner.class)

 @SpringBootTest(classes = MainApplication.class)

 public class MailTest {

     @Autowired

     MailService mailService;

     @Test

     public void sendSimpleMail(){

         mailService.sendSimpleMail("xxxxx@qq.com","标题","内容");

     }

 }

MailTest
