這篇文章主要介紹了SpringBoot如何實現(xiàn)發(fā)送QQ郵件功能，本文通過實例圖文相結(jié)合給大家介紹的非常詳細(xì)，對大家的學(xué)習(xí)或工作具有一定的參考借鑒價值,需要的朋友可以參考下

配置發(fā)送郵件

1、引入SpringBoot的Mail依賴

如果是Spring Boot應(yīng)用不需要指定版本號了

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-mail</artifactId>
</dependency>

2、配置郵箱發(fā)送的Bean

如下配置

在配置前獲取QQ郵箱授權(quán)碼；QQ郵件在Spring的Bean中密碼為授權(quán)碼。

@Configuration
public class MailConfig {

    @Bean
    public JavaMailSender getJavaMailSender() {
        JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
//        mailSender.setHost("smtp.gmail.com");
        mailSender.setHost("smtp.qq.com");
        mailSender.setPort(587);

        mailSender.setUsername("aihehe123@foxmail.com");
        mailSender.setPassword("這里是QQ郵箱的授權(quán)碼");

        Properties props = mailSender.getJavaMailProperties();
        props.put("mail.transport.protocol", "smtp");
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.debug", "true");

        return mailSender;
    }
}

3、發(fā)送測試郵件

發(fā)送普通文本

            SimpleMailMessage simpleMessage = new SimpleMailMessage();
            simpleMessage.setFrom("aihehe123@foxmail.com");
            simpleMessage.setTo("aihehe123@foxmail.com");
            simpleMessage.setSubject("test");
            simpleMessage.setText("hello");
            javaMailSender.send(simpleMessage);

發(fā)送帶附件的文本

           MimeMessage message = javaMailSender.createMimeMessage();
            MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(message, true);
            mimeMessageHelper.setFrom("aihehe123@foxmail.com");
            mimeMessageHelper.setTo("aihehe123@foxmail.com");
            mimeMessageHelper.setSubject("test");
            mimeMessageHelper.setText("hello");

            String path = "http://gif.aihe.space/dd467677ea35485da3d12326fcf36e5d.gif";
            UrlResource fileUrlResource = new UrlResource(path);
            mimeMessageHelper.addAttachment(UrlUtils.parseUrlName(path), fileUrlResource);

            javaMailSender.send(message);

4、查看效果

前兩個郵件是帶附件的，最下面一個是不帶附件的；

應(yīng)用啟動&停止郵件通知

1、配置發(fā)送郵件的模板

public class MailUtils {
    public static SimpleMailMessage makeSimpleMessage(String subject,String text){
        SimpleMailMessage simpleMessage = new SimpleMailMessage();
        simpleMessage.setFrom("aihehe123@foxmail.com");
        simpleMessage.setTo("aihehe123@foxmail.com");
        simpleMessage.setSubject(subject);
        simpleMessage.setText(text);
        return simpleMessage;
    }
}

2、應(yīng)用啟動通知

@Component
@Slf4j
public class ApplicationStartHandler implements ApplicationListener<ContextRefreshedEvent> {

    @Autowired
    JavaMailSender javaMailSender;

    @Override
    public void onApplicationEvent(ContextRefreshedEvent event) {
        javaMailSender.send(MailUtils.makeSimpleMessage("應(yīng)用啟動通知",""));
        log.info("app start mail sended");
    }
}

3、應(yīng)用停止通知；

public class XXXApplication {

    @Autowired
    JavaMailSender javaMailSender;

    public static void main(String[] args) {
        SpringApplication.run(XXXApplication.class, args);
    }


    @PreDestroy
    public void onExit() {
        log.info("###STOPing###");
        javaMailSender.send(MailUtils.makeSimpleMessage("應(yīng)用停止通知", ""));
        log.info("###STOP FROM THE LIFECYCLE###");
    }

}
