springboot整合邮件发送(163邮箱发送为例)

//先登录163邮箱获取授权

勾选后安装提示会叫你设置授权密码之类的:记住授权的密码

1.引入maven依赖
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-mail</artifactId>
</dependency>

application.yml里配置:
spring:        
  mail:
    host: smtp.163.com  //登录邮箱设置那里可以看到,第一张图所示,SMTP服务器
    password: 12222 密码是第二张图设置的授权密码.不是邮箱的登录密码
    username: 15902048215@163.com //这个是你的邮箱

@Service
public class MailService {
    @Autowired
    private JavaMailSender mailSender;

    /**
     * 发送简单文本文件
     */

    public void sendSimpleEmail(){
        try {
            SimpleMailMessage message=new SimpleMailMessage();
            message.setFrom("15902048215@163.com");
            message.setTo("513473567@qq.com");
            message.setSubject("您有订单未支付,请按时支付");
            message.setText("哈哈这是主题..............................");
            mailSender.send(message);

        }catch (Exception e){
            System.out.println("发送简单文本文件-发生异常");
        }
    }

    /**
     * 发送html文本
     * @param
     */
    @Async
    public void sendHTMLMail(){
        try {
            MimeMessage message=mailSender.createMimeMessage();
            MimeMessageHelper messageHelper=new MimeMessageHelper(message,true,"utf-8");
            messageHelper.setFrom("15902048215@163.com");
            messageHelper.setTo("513473567@qq.com");
            messageHelper.setSubject("欢迎访问");
            messageHelper.setText("<a href='www.baidu.com'>百度</a>",true);

            mailSender.send(message);
        }catch (Exception e){
        }
    }
}
