1.獲取授權(quán)碼
首先打開QQ郵箱->設(shè)置->賬戶->開啟服務(wù)POP3/SMTP開啟->獲取授權(quán)碼

- 打開服務(wù)，需要發(fā)送短信的，然后獲取授權(quán)碼
2.添加pom依賴
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
3.配置application.properties
###郵箱配置
spring.mail.host=smtp.qq.com
spring.mail.username=******* //這里填寫你的郵箱
spring.mail.password=********//這里填寫上面你獲取的授權(quán)碼
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
4.service接口
public interface MailService {
/**
* 發(fā)送簡(jiǎn)單郵件
*/
void sendMail(String to,String subject,String content);
}
5.實(shí)現(xiàn)接口
@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("*********");//發(fā)起者的郵箱
mailMessage.setTo("**********");//接受者的郵箱
mailMessage.setSubject(subject);
mailMessage.setText(content);
try {
mailSender.send(mailMessage);
System.out.println("發(fā)送簡(jiǎn)單郵件");
}catch (Exception e){
System.out.println("發(fā)送簡(jiǎn)單郵件失敗");
}
}
}
6.寫定時(shí)任務(wù)
@Service
//@Async
public class TaskService {
@Autowired
private MailService mailService;
@Scheduled(cron = "0 01 10 ? * *") //這是cron表達(dá)式
public void proces(){
mailService.sendMail("123456qq.com","標(biāo)題","內(nèi)容"); //一是接受者的郵箱，二是郵件的標(biāo)題 三是郵件的內(nèi)容
System.out.println("111");
}
}
7.最后啟動(dòng)主類
運(yùn)行結(jié)果
