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 {@Autowiredprivate 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";@Overridepublic 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 {@Autowiredprivate 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";@Overridepublic 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();}}
}

直接测试！！！

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
