   又是新的一年，發qq祝福、微信祝福給好友都太撈了，不如整點新穎的活，給好友們發祝福郵件，一來閒着沒事打發時間，二來也是爲了zb。下邊是代碼，僅供參考：

3.Controller

@RestController
@RequestMapping("/email")
public class    SendEmailController {
    private static Logger logger = LoggerFactory.getLogger(SendEmailController.class);

    @Autowired
    private SendEmailService sendEmailService;
    @Autowired
    private UserService  userService;

    /**
     * 郵件調用
     */
    @RequestMapping(value = "/simpleEmail", method = {RequestMethod.GET})
    public RspResult sendSimpleEmail(HttpServletRequest request) {
        RspResult rspResult = new RspResult();
        //去庫中取用戶郵箱
        List<User> userList = userService.findAll();
        System.out.println(userList.size());
        userList.forEach(user -> {
            sendEmailService.sendSimpleMail(user.getEmail(), "新年祝福", "可可愛的"+user.getUserName()+"：新年快樂,新的一年裏順順利利，發大財哦！最近出去記得戴口罩哦~");
        });

        rspResult.setStatus(200);
        rspResult.setMsg("調用成功");
        return rspResult;
    }
}

4.service

@Service
public class SendEmailService {

    private static Logger logger = LoggerFactory.getLogger(SendEmailService.class);

    @Autowired
    private JavaMailSender sender;


    @Value("${spring.mail.username}")
    private String fromMail;

    /**
     * 發送普通郵件
     *
     * @param toMail  收件方
     * @param subject 標題
     * @param content 郵件內容
     */
    public void sendSimpleMail(String toMail, String subject,  String content) {
        SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
        simpleMailMessage.setFrom(fromMail);
        simpleMailMessage.setTo(toMail);
        simpleMailMessage.setSubject(subject);
        simpleMailMessage.setText(content);
        try {
            sender.send(simpleMailMessage);
            logger.info("發送給:{} 郵件已經發送。 subject:{}", toMail, subject);
        } catch (Exception e) {
            logger.info("發送給:{} send mail error subject:{}", toMail, subject);
            e.printStackTrace();
        }
    }
}

5.dao

@Repository
public interface UserDao  extends JpaRepository<User,Integer> {
    public List<User> findAll();
}

6.pojo

@Data
@Entity
@Table(name = "user")
@NoArgsConstructor
@AllArgsConstructor
public class User {
    @Id
    private Integer id;
    @Column(name = "username",nullable = false)
    private String userName;
    @Column(name = "email",nullable = false)
    private String Email;
}

 7.數據庫表結構

 

Create Table

CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(20) DEFAULT NULL,
  `email` varchar(30) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=25 DEFAULT CHARSET=utf8

啓動程序後，在瀏覽器總輸入：http://localhost:8888/email/simpleEmai   即可開啓程序。

以上是代碼的主要部分，源碼已經上傳github:https://github.com/Upzzh/newYearWish
