求高手指教 这个错误怎么改啊？
代码如下： String content = code ;
java.util.Properties props = System.getProperties();
props.put("mail.host", mailSever);
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.auth","true");
MyAuth auth = new MyAuth(userName, passwd);
auth.getPasswordAuthentication();
System.out.println("auth==="+auth);
javax.mail.Session mailSession = javax.mail.Session.getInstance(props, auth);
mailSession.setDebug(true);
MimeMessage msg = new MimeMessage(mailSession);
msg.setFrom(new InternetAddress( from ));
InternetAddress to_mail = new InternetAddress("asdasd@163.com,asddsa@163.com");
msg.setRecipient(MimeMessage.RecipientType.TO,to_mail);
msg.setSubject(subject);
msg.setRecipients(MimeMessage.RecipientType.CC, this.cc );
msg.setSentDate(new java.util.Date());
msg.setText(content);
Transport transport=mailSession.getTransport("smtp");
//连接SMTP服务器
transport.connect(mailSever, userName, passwd);
//发送邮件
//Transport.send(message,message.getAllRecipients());
transport.sendMessage(msg,msg.getAllRecipients());
transport.close();
//Transport.send(msg);
System.out.println(" Success !");
