这篇文章主要讲解了“SpringBoot怎么实现发送QQ邮件”，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习“SpringBoot怎么实现发送QQ邮件”吧！
如果是Spring Boot应用不需要指定版本号了
计算
安全
数据库
网络和加速
企业服务
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>如下配置
在配置前获取QQ邮箱授权码；QQ邮件在Spring的Bean中密码为授权码。
@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("这里是QQ邮箱的授权码");
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;
}
}发送普通文本
SimpleMailMessage simpleMessage = new SimpleMailMessage();
simpleMessage.setFrom("aihehe123@foxmail.com");
simpleMessage.setTo("aihehe123@foxmail.com");
simpleMessage.setSubject("test");
simpleMessage.setText("hello");
javaMailSender.send(simpleMessage);发送带附件的文本
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);前两个邮件是带附件的，最下面一个是不带附件的；
1、配置发送邮件的模板
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、应用启动通知
@Component
@Slf4j
public class ApplicationStartHandler implements ApplicationListener<ContextRefreshedEvent> {
@Autowired
JavaMailSender javaMailSender;
@Override
public void onApplicationEvent(ContextRefreshedEvent event) {
javaMailSender.send(MailUtils.makeSimpleMessage("应用启动通知",""));
log.info("app start mail sended");
}
}3、应用停止通知；
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("应用停止通知", ""));
log.info("###STOP FROM THE LIFECYCLE###");
}
