springboot实现邮件功能：发送html格式邮件：

### 1.建springboot项目，导入依赖；application.properties配置文件，看 ###

[springboot发送邮件（1）：发送简单邮件][springboot_1]

### 2.编写服务接口，实现类： ###

/**
     * 邮件服务接口
     * Created by ASUS on 2018/5/5
     *
     * @Authod Grey Wolf
     */
    public interface MailService {
    
       
        /**
         * 发送带附件的邮件
         * @param to
         * @param subject
         * @param content
         * @param filePath
         */
        void sendAttachmentsMail(String to,String subject,String content,String filePath);
    
    }

/**
     *
     * 邮件服务类
     * Created by ASUS on 2018/5/5
     *
     * @Authod Grey Wolf
     */
    
    @Service("mailService")
    public class MailServiceImpl implements MailService {
    
        @Autowired
        private JavaMailSender mailSender;
    
        /**
         * 发送带附件的邮件
         * @param to 接受者
         * @param subject 主题
         * @param content 内容
         * @param filePath 文件路径
         */
        @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(form);
                helper.setTo(to);
                helper.setSubject(subject);
                helper.setText(content);
                FileSystemResource file=new FileSystemResource(new File(filePath));
                String fileName=filePath.substring(filePath.lastIndexOf(File.separator));
          //添加多个附件可以使用多条
          //helper.addAttachment(fileName,file);
         helper.addAttachment(fileName,file);
                mailSender.send(message);
                System.out.println("带附件的邮件发送成功");
            }catch (Exception e){
                e.printStackTrace();
                System.out.println("发送带附件的邮件失败");
            }
        }
    
    
    }

### 3.编写测试类MailTest: ###

/**
     * 发送邮件测试类
     * Created by ASUS on 2018/5/5
     *
     * @Authod Grey Wolf
     */
    @RunWith(SpringRunner.class)
    @SpringBootTest
    public class MailTest {
    
        @Autowired
        private MailService mailService;
    
        @Value("${mail.fromMail.addr}")
        private String form;
    
        @Test
        public  void sendAttachmentsMail(){
            String filePath="C:\\Users\\ASUS\\Pictures\\SharedImageServer\\contentpic\\2.jpg";
            mailService.sendAttachmentsMail(form,"带附件的邮件","有附件，请查收",filePath);
        }
    
    }

### 4.看测试结果： ###
