org.springframework.boot spring-boot-starter-mail

3.在application.properties中配置

spring.mail.host=smtp.qq.com spring.mail.username=824772535@qq.com//自己的邮箱地址 spring.mail.password=fvbiwufrqsfbbcbc//开启时获取的授权码 spring.mail.default-encoding=UTF-8##如果不加下面3句,会报530错误 spring.mail.properties.mail.smtp.auth=true spring.mail.properties.mail.smtp.starttls.enable=true spring.mail.properties.mail.smtp.starttls.required=true

4.写service接口

public interface MailService { /** * 发送简单邮件 */ void sendMail(String to,String subject,String content); }

5.实现类接口

@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("824772535@qq.com"); //发起者 mailMessage.setTo("16422802@qq.com"); //接受者 mailMessage.setSubject("朱芮林"); //标题 mailMessage.setText("abcdefghijklmnopqrstuvwxyz 9:50发送"); //发送的邮件内容 try { mailSender.send(mailMessage); System.out.println("发送简单邮件"); }catch (Exception e){ System.out.println("发送简单邮件失败"); } }}

6.定时任务

@Service //@Async public class TaskService { @Autowired private MailService mailService; @Scheduled(cron = "0 15 10 ? * MON") //corn表达式:定时为每周一早上9:50发送，可更换 public void proces(){ mailService.sendMail("16422802@qq.com","张文旭","dsf"); System.out.println("发送成功"); } }
