Spring Boot email

配置依赖

pom.xml文件

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

application.yml

spring:
  mail:
    host: smtp.163.com
    username: username
    password: password
    properties: 
      mail:
        smtp:
          auth: true
          connectiontimeout: 5000
          timeout: 5000
          writetimeout: 5000
          starttls:
            enable: true

email:
    account: username

　　

这里其实有两个注意点，因为我使用的是163邮箱，1.需要授权客户端授权密码，2. 需要勾选POP3/SMTP服务

简单示例

@Component
public class SendEmail implements SendMessage{
    @Autowired
    private JavaMailSender mailSender;

    @Value("${email.account}")
    private String account;

    @Override
    public void send(MessageForm messageForm) {
        SimpleMailMessage msg = new SimpleMailMessage();
        msg.setFrom(account);
//        msg.setTo(messageForm.getReceivers().toArray(new String[0]));

        msg.setTo("eamil1@qq.com","email2@qq.com");
        msg.setSubject(messageForm.getTitle());
        msg.setText(messageForm.getInfo());

        mailSender.send(msg);
    }
}

这里我一直报553错误，原因是未设置发送者，添加msg.setFrom()即可。
