springboot发邮件问题实例--688IT编程网

springboot发邮件问题实例先看怎么在spring boot发邮件，我们通过⼀个service来实现：

slf4j.Slf4j;

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.scheduling.annotation.Async;

import org.springframework.stereotype.Service;

@Slf4j

@Service

public class MailService {

@Autowired

JavaMailSender javaMailSender;

@Value("${mail.from}")

private String mailFrom;

@Value("${}")

private String mailTo;

@Async

public void sendSimpleMail(String subject, String content) {

SimpleMailMessage message = new SimpleMailMessage();

message.setFrom(mailFrom);

message.setTo(mailTo);

message.setSubject(subject);

message.setText(content);

try {

javaMailSender.send(message);

log.info("邮件已经发送");

} catch (Exception e) {

<("发送邮件异常", e);

}

我们在application.properties⽂件中配置邮件参数，给配置多个邮箱，并⽤分号分隔

#邮件

spring.mail.host=smtp.163

spring.mail.username=tangseng2019@163

spring.mail.password=wlf123

spring.mail.properties.mail.smtp.auth=true

spring.mail.properties.quired=true

spring.mail.properties.able=true

spring.mail.default-encoding=UTF-8

mail.from=${spring.mail.username}

<=sunwukong2019@126;zhubajie2019@126

注意spring.mail.password不是邮箱密码，⽽是授权码，需要在邮箱的“设置”中启⽤授权码：

调⽤上⾯的发送接⼝sendSimpleMail

问题来了：
