SpringBoot邮件发送

1. 添加pom依赖

   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-mail</artifactId>
   </dependency>

2. application.properties配置

   spring.mail.host=smtp.qq.com
   spring.mail.port=465
   spring.mail.username=wsyjlly@qq.com
   spring.mail.password=khhvydlbhiqjcjaj
   spring.mail.default-encoding=UTF-8
   spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
   spring.mail.properties.mail.debug=true

3. 编写邮件发送服务

   /**
    * @author wsyjlly
    * @create 2019.07.16 - 17:32
    **/
   @Component
   public class MailService {
       @Autowired
       JavaMailSender javaMailSender;
       
       //简单邮件发送
       public void sendSimpleSender(String from,String to,String cc,String subject,String content){
           SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
           simpleMailMessage.setFrom(from);
           simpleMailMessage.setTo(to);
           simpleMailMessage.setCc(cc);
           simpleMailMessage.setSubject(subject);
           simpleMailMessage.setText(content);
           javaMailSender.send(simpleMailMessage);
       }
       
       //带附件的邮件发送
       public void sendAttachFileMail(String from, String to, String subject, String content, File file) throws MessagingException {
           MimeMessage mimeMessage = javaMailSender.createMimeMessage();
           MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);
           helper.setFrom(from);
           helper.setTo(to);
           helper.setSubject(subject);
           helper.setText(content);
           helper.addAttachment(file.getName(),file);
           javaMailSender.send(mimeMessage);
   
       }
       
       public void sendMailWithImg(String from, String to, String subject, String content, String[] srcPath,String[] resIDs) throws MessagingException {
           if (srcPath.length != resIDs.length){
               System.out.println("发送失败！");
               return;
           }
           MimeMessage mimeMessage = javaMailSender.createMimeMessage();
           MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);
           helper.setFrom(from);
           helper.setTo(to);
           helper.setSubject(subject);
           helper.setText(content,true);
           for (int i = 0; i < srcPath.length; i++) {
               FileSystemResource resource = new FileSystemResource(new File(srcPath[i]));
               helper.addInline(resIDs[i],resource);
           }
           javaMailSender.send(mimeMessage);
       }
   }

4. 发送邮件

   /**
    * @author wsyjlly
    * @create 2019.06.10 - 19:00
    **/
   @RestController
   public class ControllerDemo1 {
       @Autowired
       MailService mailService;
   
       @RequestMapping("/mail1")
       public void mail1(){
           mailService.sendSimpleSender("wsyjlly@qq.com",
           "895864393@qq.com",
           "211874876@qq.com",
           "你爱我吗",
           "你这个坏孩子！");
       }
       
       @RequestMapping("/mail2")
       public void mail2() throws MessagingException {
           mailService.sendAttachFileMail("wsyjlly@qq.com","wsyjlly@qq.com","你信命吗？","你这个坏孩子！",new File("./uploadFiles/abc.gif"));
       }
       
       @RequestMapping("/mail3")
       public void mail3() throws MessagingException {
           mailService.sendMailWithImg("wsyjlly@qq.com","wsyjlly@qq.com","你信神吗？","<div>hello,坏孩子！"
                   +"<div><img src='cid:p01'/></div>"
                   +"<div><img src='cid:p02'/></div>"
                   +"</div>",
                   new String[]{"./mail/aaa.jpg","./mail/abc.gif"},
                   new String[]{"p01","p02"});
       }
   }

5. 测试链接

   • http://localhost:8080/mail1
   • http://localhost:8080/mail2
   • http://localhost:8080/mail3
6. 发送成功
