一、导入jar包
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
二、在application.properties种添加邮箱配置
QQ邮箱需要设置开启smtp服务,具体的请查询一下如何开启,此处省略
spring.mail.host=smtp.qq.com
spring.mail.username=54281****@qq.com
spring.mail.password=tneawbzduhvf****
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
三、发送邮件类
package com.example.demo.timedtask; import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component; import java.text.SimpleDateFormat;
import java.util.Date; @Component
public class Scheduler2Task {
private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss"); @Autowired
private JavaMailSender mailSender; /*
* @Scheduled(fixedRate = 6000) 上一次开始执行时间点之后6秒再执行
* @Scheduled(fixedDelay = 6000) 上一次执行完毕时间之后6秒再执行
* @Scheduled(initialDelay=1000, fixedRate=6000) 第一次延迟1秒后执行,之后按fixedRate的规则执行
* */
@Scheduled(fixedRate = 6000)/*每隔六秒钟执行一次*/
public void reportCurrentTime() {
System.out.println("现在时间:" + dateFormat.format(new Date()));
SimpleMailMessage message = new SimpleMailMessage();
message.setFrom("542813934@qq.com");
message.setTo("542813934@qq.com");
message.setSubject("主题:简单邮件1");
message.setText("测试邮件内容1");
mailSender.send(message);
}
}
