使用SpringBoot中的Schedule定时发送邮件的方法

@SpringBootApplication
@MapperScan("com.shoanjen.redis.mapper")
@EnableScheduling
public class RedisApplication {
	public static void main(String[] args) {
		SpringApplication.run(RedisApplication.class, args);
	}
}

@Component
public class ScheduleService {
    @Scheduled(fixedRate = 5000)
    //@Scheduled(fixedDelay = 5000)
    public void scheduleConsole(){
        System.out.println("定时任务要开始了哟！！！！");
    }
}

<!-- Spring Mail依赖 -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-mail</artifactId>
</dependency>

spring.mail.host=smtp.126.com
spring.mail.username=XXXXXX@126.com
spring.mail.password=这里就是你刚刚的授权码哟！

@Component
public class ScheduleService {
    @Autowired
    private JavaMailSender mailSender;
    @Scheduled(cron = "0 34 21 * * ?")
    public void scheduleMailTo(){
        SimpleMailMessage message = new SimpleMailMessage();
        //随机验证码
        Random random=new Random();
        int code=random.nextInt(9999)+1;
        // 发件人，配置文件中的邮件地址
        message.setFrom("xxxxx@126.com");
        // 收件人
        message.setTo("xxxxx@163.com");
        //设置邮件标题
        message.setSubject("注册验证码");
        // 邮件内容
        message.setText("Hello欢迎使用xxx系统，您的注册验证码为"+code);
        mailSender.send(message);
        System.out.println("邮件发送已完成哦！！！");
    }
}
