SpringBoot邮件发送

1.导入email依赖

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

2.获取邮箱授权码
------开启POP3/SMTP服务，点击生成授权码

3.编写email类

import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.mail.javamail.MimeMessageHelper;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;

//邮件发送
public class Email {
    public JavaMailSenderImpl javaMailSender(){
        JavaMailSenderImpl javaMailSender=new JavaMailSenderImpl();
        javaMailSender.setHost("smtp.qq.com");
        javaMailSender.setUsername(" ");//填写邮箱
        javaMailSender.setPassword("");//填写授权码
        return javaMailSender;
    }
    JavaMailSenderImpl mailSender=javaMailSender();
    //发送简单邮件
    public void send(String tit,String txt,String email){
        SimpleMailMessage mailMessage=new SimpleMailMessage();
        mailMessage.setSubject(tit);//标题
        mailMessage.setText(txt);//内容
        mailMessage.setFrom("");//发送者邮箱
        mailMessage.setTo(email);//收件者邮箱
        mailSender.send(mailMessage);
    }
    //发送复杂邮件
    public void send2(){
        MimeMessage mimeMessage=mailSender.createMimeMessage();
        MimeMessageHelper helper=null;
        try {
            helper=new MimeMessageHelper(mimeMessage,true);
            helper.setSubject("");
            helper.setText("");//可以编写html信息
            helper.addAttachment("",new File(""));//发送附件
            helper.setFrom("");
            helper.setTo("");
        } catch (MessagingException e) {
            e.printStackTrace();
        }

    }
}

邮件发送编写成功。
注：JavaMailSenderImpl属性也可通过properties文件和yaml文件配置

spring.mail

spring.mail.username=邮箱
spring.mail.password=你的qq授权码
spring.mail.host=smtp.qq.com
# qq需要配置ssl
spring.mail.properties.mail.smtp.ssl.enable=true
