spring boot mail

1.引入

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

2配置

  mail:
    host: smtp.163.com
    username: xxxxxxxx@163.com
    password: xxxxxxxxxxx
    default-encoding: UTF-8
    properties:
      mail:
        smtp:
          auth: true
          starttls:
            enable: true
            required: true

3.邮件接口，实现类，调用类

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

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Service;

@Service
public class MailServiceImpl implements MailService{

    @Autowired
    private JavaMailSender mailSender;
    @Value("${spring.mail.username}")
    private String from;
    @Override
    public boolean sendMail(String to, String subject, String content) {
        SimpleMailMessage simpleMailMessage=new SimpleMailMessage();
        simpleMailMessage.setFrom(from);
        simpleMailMessage.setTo(to);
        simpleMailMessage.setSubject(subject);
        simpleMailMessage.setText(content);
        try{
            mailSender.send(simpleMailMessage);
            System.err.println("yes");
            return true;
        }
        catch (Exception e){
            e.printStackTrace();
            return false;
        }
    }
}

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

@Component
@Configuration
@EnableScheduling
public class SendEmailQuartz {
    private static final Logger logger= LogManager.getLogger(SendEmailQuartz.class);

    @Autowired
    private MailService mailService;
    @Scheduled(cron="*/5 * * * * * ")
    public void aaa(){
        mailService.sendMail("xxxxxxxxx@163.com","打折","橘子1毛");
    }

}
