14.邮件发送

配置

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

yaml配置

spring:
  profiles: dev
  mail:
    username: 480233119@qq.com
    password: ouwfwazpbylabibb
    host: smtp.qq.com
    #开启加密验证
    properties:
      mail:
        smtp:
          ssl:
            enable: true

3.qq开启pop3，SMTP获得密码

1.核心类

JavaMailSenderImpl mailSender;

2.注入

@Autowired注入爆红

可以用@Resource

3.通过.send方法发送

.简单邮件

public void contextLoads(String title,String text,String to) {
    //邮件设置1：一个简单的邮件
    SimpleMailMessage message = new SimpleMailMessage();
    message.setSubject(title);
    message.setText(text);
    message.setTo(to);
    message.setFrom("@qq.com");
    mailSender.send(message);
}

5.复杂邮件

public void contextLoad2(String title,String text,String to,String imgname,String imgfile) {
    System.out.println("b");
    //邮件设置1：一个简单的邮件
    MimeMessage mimeMessage = mailSender.createMimeMessage();
    MimeMessageHelper helper= null;
    try {
        helper = new MimeMessageHelper(mimeMessage,true);
        helper.setSubject(title);
        //开启多行文本支持编程
        helper.setText(text,true);
        helper.setTo(to);
        helper.setFrom("@qq.com");
        //发送附件
        helper.addAttachment(imgname,new File(imgfile));
    } catch (MessagingException e) {
        e.printStackTrace();
    }
    mailSender.send(mimeMessage);
