首先需要进入你的qq邮箱中开启POP3/SMTP服务。

1.点击左上方设置--》账户

2.开启POP3/STMP服务，开启服务会有一个授权码，需要保存下来，配置到代码中。

3.引入pom依赖。

<dependency>
          <groupId>javax.mail</groupId>
          <artifactId>mail</artifactId>
          <version>1.4.7</version>
        </dependency>

4.配置applicationContext.xml文件

5.编写工具类

import org.springframework.transaction.annotation.Transactional;
    import javax.mail.MessagingException;
    
    public interface MailSenderSrvServices {
        /*普通格式发送
        * @recipient 收件人地址
        * @subject 主题
        * @content 正文
        * */
        @Transactional
        void sendEmail(String recipient,String subject,String content);
    
        /*带抄送
        * */
        void sendHtmlEmail(String recipient,String subject,String content) throws MessagingException, Exception;
    
    }

import com.xcq.service.MailSenderSrvServices;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.mail.javamail.JavaMailSenderImpl;
    import org.springframework.mail.javamail.MimeMessageHelper;
    import org.springframework.stereotype.Service;
    import javax.mail.Message;
    import javax.mail.MessagingException;
    import javax.mail.internet.MimeMessage;
    
    @Service("MailSenderSrvService")
    public class MailSenderSrvServiceImpl implements MailSenderSrvServices {
        @Autowired
        private JavaMailSenderImpl mailSender;
    
        /**
         *   JavaMailSenderImpl支持MimeMessages和SimpleMailMessages。
         * MimeMessages为复杂邮件模板，支持文本、附件、html、图片等。
         * SimpleMailMessages实现了MimeMessageHelper，为普通邮件模板，支持文本
         */
    
    
        /**
         * 描述：Spring 依赖注入
         * @author wanghaoyu
         * @date
         * @version 1.0
         * @param mailSender
         * @since 1.8
         *
         */
        public void setMailSender(JavaMailSenderImpl mailSender) {
            this.mailSender = mailSender;
        }
    
        /**
         * 单发
         *
         * @param recipient 收件人
         * @param subject 主题
         * @param content 内容
         */
        @Override
        public void sendEmail(String recipient,String subject,String content) {
            MimeMessage mimeMessage = mailSender.createMimeMessage();
            try {
                MimeMessageHelper messageHelper = new MimeMessageHelper(mimeMessage,true,"UTF-8");
                messageHelper.setFrom("xx@qq.com");//发件人
                messageHelper.setTo(recipient);
                messageHelper.setSubject(subject);
                messageHelper.setText(content,true);//true代表支持html格式
                mailSender.send(mimeMessage);
            } catch (MessagingException e) {
                    e.printStackTrace();
            }
    
    
        }
    
    
        @Override
        public void sendHtmlEmail(String recipient,String subject,String content) throws Exception {
            MimeMessage mimeMessage = mailSender.createMimeMessage();
            try {
                MimeMessageHelper messageHelper = new MimeMessageHelper(mimeMessage,true,"UTF-8");
                messageHelper.setFrom("xx@qq.com");//发件人
                messageHelper.setTo(recipient);
                messageHelper.setSubject(subject);
                messageHelper.setText(content,true);
                mimeMessage.setRecipients(Message.RecipientType.CC,"xx@qq.com");//抄送人
                mailSender.send(mimeMessage);
            } catch (MessagingException e) {
                e.printStackTrace();
            }
        }
    
    }

6.编写测试类
