在这里已QQ邮箱发送为案例

1、首先我们需要进入QQ邮箱顶部的设置

2、点击进入以后会出现导航栏请选中你的账户

3、开启POP3/SMTP服务并申请获得授权码

4、开始SpringBoot整合Email操作

Maven pom导入依赖

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

5、在application.properties 或者application.yml文件中配置您的邮箱信息

spring.mail.host=smtp.qq.com
spring.mail.username=QQ号@qq.com
spring.mail.password=填写你申请的授权码
spring.mail.defaultEncodint=UTF-8

6、开始发送邮件

import com.bean.springcloudcommon.model.Email;
import com.bean.springcloudemail.mapper.EmailMapper;
import com.bean.springcloudemail.servie.EmailService;
import org.springframework.beans.factory.annotation.Autowired;

        emailMapper.insert(email);
        try {

        simpleMailMessage.setText("来来来 给你发了一封简单邮件");
        javaMailSender.send(simpleMailMessage);
    }

    private void sendQQEmail(String userEmail, String key, Long emailId) throws MessagingException {
        MimeMessage mimeMessage = javaMailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);
        //配置地址来源
        helper.setFrom("2538552544@qq.com");
        //发送邮箱地址
        helper.setTo(userEmail);
        //邮箱标题
        helper.setSubject("注册账户");
        //邮箱内容
        helper.setText("<html><body><a href='http://localhost:9005/email/api/email/validateEmail/" + emailId + "?key=" + key + "'>请点击我完成注册</a></body></htm>", true);
        //发送
        javaMailSender.send(mimeMessage);
    }


    /**
     * 发送带附件的邮件
     *
     * @param userEmail 用户邮箱
     * @param filePath  文件地址 也可以是文件数组传递多个附件
     * @throws MessagingException
     */
    private void sendAttachmentQQEmail(String userEmail, String filePath) throws MessagingException {
        MimeMessage mimeMessage = javaMailSender.createMimeMessage();
        //自定义发送格式工具类
        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);
        helper.setFrom("2538552544@qq.com");
        helper.setTo(userEmail);
        helper.setSubject("发送一封带附件的邮箱");
        helper.setText("发送带附件的邮箱文件");
        File file = new File(filePath);
        FileSystemResource fileSystemResource = new FileSystemResource(file);
        String fileName = filePath.substring(filePath.lastIndexOf(File.separator));
        //可以添加多个的附件
        helper.addAttachment(fileName, fileSystemResource);
        javaMailSender.send(mimeMessage);

    }

}
