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。
