SpringBoot整合Email（电子邮件服务）

（1）、导入starter依赖

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

（2）、配置相关属性

 spring.mail.username=fanqixxxx@163.com
 #spring.mail.password   填写授权码
 spring.mail.password=xxxxxxx
 #spring.mail.host   填写邮箱供应的SMTP地址
 spring.mail.host=smtp.163.com
 spring.mail.properties.mail.smtp.ssl.enable=true

（3）、使用JavaMailSenderImpl发送邮件

 package cn.coreqi.service;

 import org.springframework.beans.factory.annotation.Autowired;
 import org.springframework.mail.SimpleMailMessage;
 import org.springframework.mail.javamail.JavaMailSenderImpl;
 import org.springframework.mail.javamail.MimeMessageHelper;
 import org.springframework.stereotype.Service;

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

 @Service
 public class EmailService {
     @Autowired
     private JavaMailSenderImpl javaMailSender;
     //简单邮件测试
     public void sendSimple(){
         SimpleMailMessage message = new SimpleMailMessage();
         message.setSubject("email测试");
         message.setText("邮件测试内容");
         message.setTo("fanqixxxx@vip.qq.com");
         message.setFrom("fanqixxxx@163.com");
         javaMailSender.send(message);
     }
     //复杂邮件测试
     public void sendComplicated() throws MessagingException {
         //创建一个复杂的消息邮件
         MimeMessage mimeMessage = javaMailSender.createMimeMessage();
         //用MimeMessageHelper来包装MimeMessage
         MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage,true);
         mimeMessageHelper.setSubject("email测试");
         mimeMessageHelper.setText("邮件测试内容");
         mimeMessageHelper.setTo("fanqixxxx@vip.qq.com");
         mimeMessageHelper.setFrom("fanqixxxx@163.com");
         mimeMessageHelper.addAttachment("meinv.jpg",new File("D:\\meinv.jpg"));
         javaMailSender.send(mimeMessage);

     }
 }

*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。
