SpringBoot实现发送邮箱

1、在邮箱服务中开启IMAP/SMTP服务和POP3/SMTP服务并获取授权码

 

2、在application.yml中配置邮箱服务 

spring:
  #配置邮件服务
  mail:
    host: smtp.126.com #配置SMTP服务器
    default-encoding: utf-8
    username: [e-mail]  #发送邮件方
    password: xxxxxxxxxxxxx  #这是刚刚获取的授权码
    properties:
      mail:
        smtp:
          ssl:
            enable: true
            required: true
          timeout: 10000
          connectiontimeout: 10000
          writetimeout: 10000

3、在SpringBoot中导入依赖包 

<!-- 发送邮件 -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-mail</artifactId>
		</dependency>

4、编写发送邮件java工具服务类 

@Service
@Slf4j
public class MailService {


    @Autowired
    private JavaMailSender mailSender;

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



    public String getUserName(){
        return SENDER;
    }

    /**
     * 发送普通邮件
     *
     * @param to      收件人
     * @param subject 主题
     * @param content 内容
     */
    public void sendSimpleMailMessge(String to, String subject, String content) {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom(SENDER);
        message.setTo(to);
        message.setSubject(subject);
        message.setText(content);
        try {
            mailSender.send(message);
        } catch (Exception e) {
            log.error("发送简单邮件时发生异常!", e);
        }
    }

    /**
     * 发送 HTML 邮件
     *
     * @param to      收件人
     * @param subject 主题
     * @param content 内容
     */

    public void sendMimeMessge(String to, String subject, String content) {
        MimeMessage message = mailSender.createMimeMessage();
        try {
            //true表示需要创建一个multipart message
            MimeMessageHelper helper = new MimeMessageHelper(message, true);
            helper.setFrom(SENDER);
            helper.setTo(to);
            helper.setSubject(subject);
            helper.setText(content, true);
            mailSender.send(message);
        } catch (MessagingException e) {
            log.error("发送MimeMessge时发生异常！", e);
        }
    }

    /**
     * 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
     */
    public void sendMimeMessge(String to, String subject, String content, String filePath) {
        MimeMessage message = mailSender.createMimeMessage();
        try {
            //true表示需要创建一个multipart message
            MimeMessageHelper helper = new MimeMessageHelper(message, true);
            helper.setFrom(SENDER);
            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);

            mailSender.send(message);
        } catch (MessagingException e) {
            log.error("发送带附件的MimeMessge时发生异常！", e);
        }
    }

    /**
     * 发送带静态文件的邮件
     *
     * @param to       收件人
     * @param subject  主题
     * @param content  内容
     * @param rscIdMap 需要替换的静态文件
     */
    public void sendMimeMessge(String to, String subject, String content, Map<String, String> rscIdMap) {
        MimeMessage message = mailSender.createMimeMessage();
        try {
            //true表示需要创建一个multipart message
            MimeMessageHelper helper = new MimeMessageHelper(message, true);
            helper.setFrom(SENDER);
            helper.setTo(to);
            helper.setSubject(subject);
            helper.setText(content, true);

            for (Map.Entry<String, String> entry : rscIdMap.entrySet()) {
                FileSystemResource file = new FileSystemResource(new File(entry.getValue()));
                helper.addInline(entry.getKey(), file);
            }
            mailSender.send(message);
        } catch (MessagingException e) {
            log.error("发送带静态文件的MimeMessge时发生异常！", e);
        }
    }
}

其中@Value("${spring.mail.username}")表示从配置文件中读取邮箱名称。

5、测试发送邮件 

@Autowired
private MailService mailService;

@RequestMapping("/test/oa/test")
    public ModelAndView test(Params params){
        ModelAndView mav = new ModelAndView();
        mav.setViewName("index");
        mailService.sendMimeMessge("[e-mail]","测试","测试成功");
        return mav;
    }
