5 整合第三方技术

5.17 发送多部件邮件

5.17.1 发送多部件邮件

之前咱们已经完成 了简单邮件的发送

现在我们来玩儿点儿花的

修改发送邮件的实现类

package com.dingjiaxiong.service.impl;

import com.dingjiaxiong.service.SendMailService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Service;

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

/**
 * ClassName: SendMailServiveImpl
 * date: 2022/10/22 14:44
 *
 * @author DingJiaxiong
 */

@Service
public class SendMailServiceImpl implements SendMailService {

    @Autowired
    private JavaMailSender javaMailSender;

    //发送人
    private String from = "1xxxxxxx2@qq.com";
    //接收人
    private String to = "3xxxxxx1@qq.com";
    //标题
    private String subject = "测试邮件";
    //正文
    private String context = "点开有惊喜";

    @Override
    public void sendMail() {

        try {

            MimeMessage message = javaMailSender.createMimeMessage();
            MimeMessageHelper helper = new MimeMessageHelper(message);
            helper.setFrom(from + "(小甜甜)");
            helper.setTo(to);
            helper.setSubject(subject);
            helper.setText(context,true);

            javaMailSender.send(message);

        } catch (Exception e) {
            e.printStackTrace();
        }

    }
}

直接测试！！！

发送成功

看看邮件

直接点

OK， 没毛病【祝福祖国】

这只是写了一个链接，也可以加上图片

随便找一个

再次发送

妙啊

5.17.2 添加附件

先打个jar 包，好家伙，打jar 包的时候又执行了一次

把这玩意儿作为附件发送过去

package com.dingjiaxiong.service.impl;

import com.dingjiaxiong.service.SendMailService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Service;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.io.File;

/**
 * ClassName: SendMailServiveImpl
 * date: 2022/10/22 14:44
 *
 * @author DingJiaxiong
 */

@Service
public class SendMailServiceImpl implements SendMailService {

    @Autowired
    private JavaMailSender javaMailSender;

    //发送人
    private String from = "16xxxxxxxx2@qq.com";
    //接收人
    private String to = "30xxxxxxxxx1@qq.com";
    //标题
    private String subject = "测试邮件";
    //正文
    private String context = "点开有惊喜";

    @Override
    public void sendMail() {

        try {

            MimeMessage message = javaMailSender.createMimeMessage();
            MimeMessageHelper helper = new MimeMessageHelper(message,true);
            helper.setFrom(from + "(小甜甜)");
            helper.setTo(to);
            helper.setSubject(subject);
            helper.setText(context,true);

            //添加附件,直接把这个程序打成jar 包给它发过去
            File f1 = new File("D:\\DingJiaxiong\\IdeaProjects\\SpringBootStudyHeiMa\\springboot\\springboot_23_mail\\target\\springboot_23_mail-0.0.1-SNAPSHOT.jar");
            //再添加一张图片
            File f2 = new File("D:\\DingJiaxiong\\IdeaProjects\\SpringBootStudyHeiMa\\springboot\\springboot_23_mail\\src\\main\\resources\\test.png");

            helper.addAttachment(f1.getName(),f1);
            helper.addAttachment("我们一定能够成为我们想要成为的人.png",f2);

            javaMailSender.send(message);

        } catch (Exception e) {
            e.printStackTrace();
        }

    }
}

OK，发送成功了，看看

就是这样

如果更换了邮箱服务，一定要在配置中修改【同样的需要去申请一个“密码”】

OK

回顾一下
