SpringBoot整合Email（電子郵件服務）

（1）、導入starter依賴

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

（2）、配置相關屬性

spring.mail.username=[e-mail]
#spring.mail.password   填寫授權碼
spring.mail.password=xxxxxxx
#spring.mail.host   填寫郵箱供應的SMTP地址
spring.mail.host=smtp.163.com
spring.mail.properties.mail.smtp.ssl.enable=true

（3）、使用JavaMailSenderImpl發送郵件

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;
    //簡單郵件測試
    public void sendSimple(){
        SimpleMailMessage message = new SimpleMailMessage();
        message.setSubject("email測試");
        message.setText("郵件測試內容");
        message.setTo("[e-mail]");
        message.setFrom("[e-mail]");
        javaMailSender.send(message);
    }
    //復雜郵件測試
    public void sendComplicated() throws MessagingException {
        //創建一個復雜的消息郵件
        MimeMessage mimeMessage = javaMailSender.createMimeMessage();
        //用MimeMessageHelper來包裝MimeMessage
        MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage,true);
        mimeMessageHelper.setSubject("email測試");
        mimeMessageHelper.setText("郵件測試內容");
        mimeMessageHelper.setTo("[e-mail]");
        mimeMessageHelper.setFrom("[e-mail]");
        mimeMessageHelper.addAttachment("meinv.jpg",new File("D:\\meinv.jpg"));
        javaMailSender.send(mimeMessage);

    }
}

 

*我在測試代碼的過程中發生了javax.mail.MessagingException: Could not connect to SMTP host: smtp.163.com, port: 465, response: 554，后即使關閉了SSL連接還是會發生25端口異常。借鑒https://blog.csdn.net/a2279860a/article/details/59012885后懷疑是運營商封禁了我的端口，於是用中國聯通的流量測試了一下通過測試。so。如果你也發生了端口問題，建議切換一下網絡環境進行測試。當然這種問題的發生也不一定是網絡的問題。　　多說一句，移動的網垃圾的很。Google掛VPN我就忍了，很多國內的網站還要掛VPN。
