具体方法如下：

import lombok.extern.slf4j.Slf4j;import java.util.Properties;import javax.mail.*;import javax.mail.internet.AddressException;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeMessage;@Slf4jpublic class SendMailUtil {    public static boolean doSendEmail(String smtpHost, final String fromUser,                final String fromUserPassWord, String userName, String emailPort, String toUser, String subject,                String messageText) throws Exception {    boolean flag = false;    try {      Properties props = new Properties();      props.put("mail.smtp.host", smtpHost);      props.put("mail.smtp.port", emailPort);      props.put("mail.smtp.auth", "true");      Session session = Session.getDefaultInstance(props, new Authenticator(){        protected PasswordAuthentication getPasswordAuthentication() {          return new PasswordAuthentication(fromUser, fromUserPassword);        }});      MimeMessage message = new MimeMessage(session);      // 发件人      InternetAddress from = new InternetAddress(fromUser);      message.setFrom(from);      // 收件人      InternetAddress to = new InternetAddress(toUser);      message.setRecipient(Message.RecipientType.TO, to);      // 邮件标题      message.setSubject(subject);      // 邮件内容,也可以使纯文本"text/plain"      message.setContent(messageText, "text/html;charset=GBK");      message.saveChanges();      Transport transport = session.getTransport("smtp");      // smtp验证，就是你用来发邮件的邮箱用户名密码      transport.connect(smtpHost, userName, fromUserPassword);      // 发送      transport.sendMessage(message, message.getAllRecipients());      transport.close();      flag = true;    } catch (AddressException e) {      log.error("地址异常:{}", e);      throw e;    } catch (MessagingException e) {      log.error("消息异常:{}", e);      throw e;    } catch (Exception e) {      log.error("系统异常:{}", e);      throw e;    }    return flag;  }}
