Spring Boot配置

qq

spring:
  mail:
    host: smtp.qq.com #發送郵件服務器
    username: [e-mail] #QQ郵箱
    password: xxxxxxxxxxx #客戶端授權碼
    protocol: smtp #發送郵件協議
    properties.mail.smtp.auth: true
    properties.mail.smtp.port: 465 #端口號465或587
    properties.mail.display.sendmail: Javen #可以任意
    properties.mail.display.sendname: Spring Boot Guide Email #可以任意
    properties.mail.smtp.starttls.enable: true
    properties.mail.smtp.starttls.required: true
    properties.mail.smtp.ssl.enable: true
    default-encoding: utf-8
    from: [e-mail] #與上面的username保持一致,這個是發送郵件方

調用JavaMailSender接口發送郵件

• Service

import javax.mail.MessagingException;
 
public interface IMailService {
    /**
     * 發送文本郵件
     * @param to
     * @param subject
     * @param content
     */
    public void sendSimpleMail(String to, String subject, String content);
 
    public void sendSimpleMail(String to, String subject, String content, String... cc);
 
    /**
     * 發送HTML郵件
     * @param to
     * @param subject
     * @param content
     * @throws MessagingException
     */
    public void sendHtmlMail(String to, String subject, String content) throws MessagingException;
 
    public void sendHtmlMail(String to, String subject, String content, String... cc);
 
    /**
     * 發送帶附件的郵件
     * @param to
     * @param subject
     * @param content
     * @param filePath
     * @throws MessagingException
     */
    public void sendAttachmentsMail(String to, String subject, String content, String filePath) throws MessagingException;
 
    public void sendAttachmentsMail(String to, String subject, String content, String filePath, String... cc);
 
    /**
     * 發送正文中有靜態資源的郵件
     * @param to
     * @param subject
     * @param content
     * @param rscPath
     * @param rscId
     * @throws MessagingException
     */
    public void sendResourceMail(String to, String subject, String content, String rscPath, String rscId) throws MessagingException;
 
    public void sendResourceMail(String to, String subject, String content, String rscPath, String rscId, String... cc);
 
} 

• ServiceImpl

@Component
public class IMailServiceImpl implements IMailService {
	@Autowired
    private JavaMailSender mailSender;
	@Value("${spring.mail.from}")
    private String from;
	//具體實現請繼續向下閱讀
}

1. 發送文本郵件

 /**
     * 發送文本郵件
     * @param to
     * @param subject
     * @param content
     */
    @Override
    public void sendSimpleMail(String to, String subject, String content) {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom(from);
        message.setTo(to);
        message.setSubject(subject);
        message.setText(content);
        mailSender.send(message);
    }
 
    @Override
    public void sendSimpleMail(String to, String subject, String content, String... cc) {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom(from);
        message.setTo(to);
        message.setCc(cc);
        message.setSubject(subject);
        message.setText(content);
        mailSender.send(message);
    }

2. 發送html郵件

 /**
     * 發送HTML郵件
     * @param to
     * @param subject
     * @param content
     */
    @Override
    public void sendHtmlMail(String to, String subject, String content) throws MessagingException {
        MimeMessage message = mailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(message, true);
        helper.setFrom(from);
        helper.setTo(to);
        helper.setSubject(subject);
        helper.setText(content, true);
 
        mailSender.send(message);
    }

3. 發送帶附件的郵件

 /**
     * 發送帶附件的郵件
     * @param to
     * @param subject
     * @param content
     * @param filePath
     */
    public void sendAttachmentsMail(String to, String subject, String content, String filePath) throws MessagingException {
        MimeMessage message = mailSender.createMimeMessage();
 
        MimeMessageHelper helper = new MimeMessageHelper(message, true);
        helper.setFrom(from);
        helper.setTo(to);
        helper.setSubject(subject);
        helper.setText(content, true);
 
        FileSystemResource file = new FileSystemResource(new File(filePath));
        String fileName = filePath.substring(filePath.lastIndexOf(File.separator));
        helper.addAttachment(fileName, file);
 
        mailSender.send(message);
    }

4. 發送正文中有靜態資源的郵件

/**
     * 發送正文中有靜態資源的郵件
     * @param to
     * @param subject
     * @param content
     * @param rscPath
     * @param rscId
     */
    public void sendResourceMail(String to, String subject, String content, String rscPath, String rscId) throws MessagingException {
        MimeMessage message = mailSender.createMimeMessage();
 
        MimeMessageHelper helper = new MimeMessageHelper(message, true);
        helper.setFrom(from);
        helper.setTo(to);
        helper.setSubject(subject);
        helper.setText(content, true);
 
        FileSystemResource res = new FileSystemResource(new File(rscPath));
        helper.addInline(rscId, res);
 
        mailSender.send(message);
    }
