Springboot加入邮件通知功能

1、pom文件中设置

            org.springframework
            spring-context-support
            RELEASE
            compile
        
        
            com.sun.mail
            javax.mail
            1.5.6
        

2、定义配置文件内容

# 邮件通知配置
notify.mail.enable=true
notify.mail.host=smtp.qq.com
[email protected]
notify.mail.password=授权码
[email protected]
[email protected]

3、读取

@ConfigurationProperties(prefix = "notify")
public class NotifyProperties {
    private Mail mail;

    public Mail getMail() {
        return mail;
    }

    public void setMail(Mail mail) {
        this.mail = mail;
    }

    public static class Mail {
        private boolean enable;
        private String host;
        private String username;
        private String password;
        private String sendfrom;
        private String sendto;

        public boolean isEnable() {
            return enable;
        }

        public void setEnable(boolean enable) {
            this.enable = enable;
        }

        public String getHost() {
            return host;
        }

        public void setHost(String host) {
            this.host = host;
        }

        public String getUsername() {
            return username;
        }

        public void setUsername(String username) {
            this.username = username;
        }

        public String getPassword() {
            return password;
        }

        public void setPassword(String password) {
            this.password = password;
        }

        public String getSendfrom() {
            return sendfrom;
        }

        public void setSendfrom(String sendfrom) {
            this.sendfrom = sendfrom;
        }

        public String getSendto() {
            return sendto;
        }

        public void setSendto(String sendto) {
            this.sendto = sendto;
        }
    }
}

4、注入

@Configuration
@EnableConfigurationProperties(NotifyProperties.class)
public class NotifyAutoConfiguration {

    private final NotifyProperties properties;

    public NotifyAutoConfiguration(NotifyProperties properties) {
        this.properties = properties;
    }

    @Bean
    public NotifyService notifyService(){
        NotifyService notifyService = new NotifyService();

        NotifyProperties.Mail mailConfig = properties.getMail();
        if(mailConfig.isEnable()) {
            notifyService.setMailSender(mailSender());
            notifyService.setSendFrom(mailConfig.getSendfrom());
            notifyService.setSendTo(mailConfig.getSendto());
        }
        return notifyService;
    }

    @Bean
    public JavaMailSender mailSender(){
        NotifyProperties.Mail mailConfig = properties.getMail();
        JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
        mailSender.setHost(mailConfig.getHost());
        mailSender.setUsername(mailConfig.getUsername());
        mailSender.setPassword(mailConfig.getPassword());
        return mailSender;
    }
}

5、设置服务方法

/**
 * 通知服务类
 */
@Data
public class NotifyService {
    private MailSender mailSender;
    private String sendFrom;
    private String sendTo;

    /**
     * 邮件消息通知,
     * 接收者在spring.mail.sendto中指定
     *
     * @param subject 邮件标题
     * @param content 邮件内容
     */
    @Async
    public void notifyMail(String subject, String content) {
        if (mailSender == null)
            return;

        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom(sendFrom);
        message.setTo(sendTo);
        message.setSubject(subject);
        message.setText(content);
        mailSender.send(message);
    }

    private String getTemplateId(NotifyType notifyType, List> values) {
        for (Map item : values) {
            String notifyTypeStr = notifyType.getType();

            if (item.get("name").equals(notifyTypeStr))
                return item.get("templateId");
        }
        return null;
    }
}

6、调用

@Test
    public void email(){
        notifyService.notifyMail("新订单通知", "测试订单号");
    }
