SpringBoot整合Email（电子邮件服务）

（1）、导入starter依赖

1         <dependency>
2             <groupId>org.springframework.boot</groupId>
3             <artifactId>spring-boot-starter-mail</artifactId>
4         </dependency>

（2）、配置相关属性

1 [email protected]
2 #spring.mail.password   填写授权码
3 spring.mail.password=xxxxxxx
4 #spring.mail.host   填写邮箱供应的SMTP地址
5 spring.mail.host=smtp.163.com
6 spring.mail.properties.mail.smtp.ssl.enable=true

（3）、使用JavaMailSenderImpl发送邮件

 1 package cn.coreqi.service;
 2 
 3 import org.springframework.beans.factory.annotation.Autowired;
 4 import org.springframework.mail.SimpleMailMessage;
 5 import org.springframework.mail.javamail.JavaMailSenderImpl;
 6 import org.springframework.mail.javamail.MimeMessageHelper;
 7 import org.springframework.stereotype.Service;
 8 
 9 import javax.mail.MessagingException;
10 import javax.mail.internet.MimeMessage;
11 import java.io.File;
12 
13 @Service
14 public class EmailService {
15     @Autowired
16     private JavaMailSenderImpl javaMailSender;
17     //简单邮件测试
18     public void sendSimple(){
19         SimpleMailMessage message = new SimpleMailMessage();
20         message.setSubject("email测试");
21         message.setText("邮件测试内容");
22         message.setTo("[email protected]");
23         message.setFrom("[email protected]");
24         javaMailSender.send(message);
25     }
26     //复杂邮件测试
27     public void sendComplicated() throws MessagingException {
28         //创建一个复杂的消息邮件
29         MimeMessage mimeMessage = javaMailSender.createMimeMessage();
30         //用MimeMessageHelper来包装MimeMessage
31         MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage,true);
32         mimeMessageHelper.setSubject("email测试");
33         mimeMessageHelper.setText("邮件测试内容");
34         mimeMessageHelper.setTo("[email protected]");
35         mimeMessageHelper.setFrom("[email protected]");
36         mimeMessageHelper.addAttachment("meinv.jpg",new File("D:\\meinv.jpg"));
37         javaMailSender.send(mimeMessage);
38 
39     }
40 }

*我在测试代码的过程中发生了javax.mail.MessagingException: Could not connect to SMTP host: smtp.163.com, port: 465, response: 554，后即使关闭了SSL连接还是会发生25端口异常。借鉴https://blog.csdn.net/a2279860a/article/details/59012885后怀疑是运营商封禁了我的端口，于是用中国联通的流量测试了一下通过测试。so。如果你也发生了端口问题，建议切换一下网络环境进行测试。当然这种问题的发生也不一定是网络的问题。　　多说一句，移动的网垃圾的很。Google挂VPN我就忍了，很多国内的网站还要挂VPN。
