springboot send mail (4): send mail with static resources

Springboot implements the mail function: send mail with static resources (static resources generally refer to pictures)

1. Build a springboot project, import dependencies; application.properties configuration file, see

springboot send mail (1): send simple mail

2. Write the service interface and implement the class:

/**
 * Mail service interface
 * Created by ASUS on 5/5/2018
 *
 * @Authod Grey Wolf
 */
 public interface MailService {


    /**
      * Send mail with static resources
      * @param to
 * @param subject
 * @param content
 * @param imgPath
 * @param imgId
 */
 void   sendInlineResourceMail (String to , String subject , String content , String imgPath , String imgId) ;
 }

/**
 *
 * 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;
@Value("${mail.fromMail.addr}")
    private String form;    
    

    /**
      * Send mail with static resources
      * @param to recipient
 * @param subject subject
 * @param content content
 * @param imgPath image path
 * @param imgId image number
 */
 @Override
 public void sendInlineResourceMail (String to , String subject , String content , String imgPath , String imgId) {                                 
        MimeMessage message=mailSender.createMimeMessage();
        try {
            MimeMessageHelper helper= new MimeMessageHelper(message ,true ) ;
             helper.setFrom( form ) ;
             helper.setTo(to) ;
             helper.setSubject(subject) ;
 //Remember to set it to true, if there is no
 helper.setText( content ,true ) ;
 FileSystemResource file= new FileSystemResource( new File(imgPath)) ;
 helper.addInline(imgId , file) ;
 mailSender .send (message) ;
 System.out .println ( "Successful sending mail with static resources" ) ;
                                                                                }catch (Exception e){
            e.printStackTrace() ;
 System.out             .println ( "Failed to send mail with static resources" ) ;
 }        
    }


}

3. Write the test class MailTest:

/**
 * Send mail test class
 * Created by ASUS on 5/5/2018
 *
 * @Authod Grey Wolf
 */
 @RunWith (SpringRunner. class )
 @SpringBootTest
 public class MailTest {

    @Autowired
private MailService mailService;
@Value("${mail.fromMail.addr}")
    private String form;
    
    

    @Test
    public void sendInlineResourceMail(){
        String imgId="2";
        String content="<html><body>这是有图片的邮件：<img src=\'cid:"+imgId + "\'></body></html>";
        String imgPath="C:\\Users\\ASUS\\Pictures\\SharedImageServer\\contentpic\\2.jpg";
        mailService.sendInlineResourceMail(form,"这是有图片的邮件",content,imgPath,imgId);
    }

}

4.看测试结果：

我的座右铭：不会，我可以学；落后，我可以追赶；跌倒，我可以站起来；我一定行。
