Spring Boot如何整合定时任务(邮件发送)呢?

SpringBoot整合定时任务的实现思路:
    1.借助@EnableScheduling注解开启定时任务配置类
    2.编写相应的业务代码,即可实现定时任务的效果

 
//1.引入相关依赖

<!--定时任务依赖-->
<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!--email依赖-->
<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
 
2、编写application.properties配置文件
spring.mail.username=admin@java265.com
spring.mail.password=XXXXXX
spring.mail.host=smtp.google.com
# 开启加密验证
spring.mail.properties.mail.smtp.ssl.enable=true


3、创建定时任务配置类
@Configuration
@EnableScheduling
public class ScheduleConfiguration {
}


4、编写测试类
@Component
public class TestClass {
    private Logger logger = LoggerFactory.getLogger(getClass());
    private final AtomicInteger counts = new AtomicInteger();
    @Autowired
    JavaMailSenderImpl mailSender;

    @Scheduled(fixedRate = 2000)
    public void execute() throws MessagingException {
        MimeMessage message = mailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(message, true);
        helper.setSubject("------邮件测试------");
        helper.setText("~~~我是邮件正文哦！~~~");
        helper.setTo("222@java265.com");
        helper.setFrom("888@java265.com");
        mailSender.send(helper.getMimeMessage());
        logger.info("[execute][定时第 ({}) 次执行]", counts.incrementAndGet());
    }
}
