跪求JavaMail认证方式的设置
CRAM-MD5,LOGIN,PLAIN这几个如何在JavaMail属性中设置,哪为大哥知道的告诉小弟一下,谢谢了,在线等,下面是部分代码:
public   boolean   sendAlertMail(AlertConfBean   alertConfBean)
{
String   content   =   createAlertMail();

smtpHost   =   alertConfBean.getMailServer();
receiver   =   alertConfBean.getMailAddress();
userID   =   alertConfBean.getAuthUserID();
password   =   alertConfBean.getAuthPassword();
subject   =   alertConfBean.getMailHeader();

if   (!checkMailField())
{
return   false;
}
Properties   properties   =   new   Properties();
properties.put( "mail.smtp.host ",   smtpHost);
properties.put( "mail.smtp.auth ",   "true ");

Session   session   =   Session.getDefaultInstance(properties,
new   Authenticator()
{
public   PasswordAuthentication   getPasswordAuthentication()
{
return   new   PasswordAuthentication(userID,   password);
}
});

MimeMessage   mimeMsg   =   new   MimeMessage(session);

try
{

mimeMsg.setFrom(new   InternetAddress(sender));

mimeMsg.setRecipients(Message.RecipientType.TO,   parse(receiver));

mimeMsg.setSubject(subject,   "SHIFT-JIS ");
MimeBodyPart   part   =   new   MimeBodyPart();
part.setText(content   ==   null   ?   " "   :   content,   "SHIFT-JIS ");

part.setContent(content.toString(),   "text/plain;charset=SHIFT-JIS ");
Multipart   multipart   =   new   MimeMultipart();
multipart.addBodyPart(part);
mimeMsg.setContent(multipart);
mimeMsg.setSentDate(new   Date());
Transport.send(mimeMsg);
return   true;
}   catch   (MessagingException   exception)
{
m_log.error( "MessageException ",   exception);
return   false;
}

}
