springtask定時(shí)發(fā)送郵件

開啟設(shè)置

按照 打開QQ郵箱->設(shè)置->開啟服務(wù)POP3/SMTP開啟->獲取授權(quán)碼

添加pom依賴

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

配置application.properties

spring.mail.host=smtp.qq.com
spring.mail.username=1729713807@qq.com
spring.mail.password=udmnwkaxeixofbae
spring.mail.default-encoding=UTF-8


##如果不加下面3句,會(huì)報(bào)530錯(cuò)誤
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true

第三行是開啟的POP3的授權(quán)碼 每個(gè)人都不一樣

Service接口

public interface MailService {
    void sendMail(String to,String subject,String content);
}

Service實(shí)現(xiàn)類

@Service("mailService")
public class MailServiceImpl implements MailService {
    @Autowired
    private JavaMailSender mailSender;

    @Override
    public void sendMail(String to, String subject, String content) {
        SimpleMailMessage mailMessage=new SimpleMailMessage();
        mailMessage.setFrom("1062273622@qq.com");//發(fā)起者
        mailMessage.setTo(to);//接受者
        mailMessage.setSubject(subject);
        mailMessage.setText(content);
        try {
            mailSender.send(mailMessage);
            System.out.println("發(fā)送簡單郵件");
        }catch (Exception e){
            System.out.println("發(fā)送簡單郵件失敗");
        }
    }
}

每15秒發(fā)送一份電子郵件

@Service
//@Async
public class TaskService {
    @Autowired
    private MailService mailService;

    @Scheduled(cron = "*/15 * * * *  ?")
    public void proces(){
        mailService.sendMail("86884571@qq.com","簡單郵件","我是測試");
        System.out.println("111");
    }
}
