用javamail发送邮件时,为什么会发生证明会失败(authentication failed)
public void sendEmail(String[] to, String subject, String text,
String from, String password) {
try
{
String host= "smtp.163.com ";
String username= "gq800307 ";
Properties props = new Properties();
props.put( "mail.smtp.host ", host);
props.put( "mail.smtp.auth ", "true "); // 这样才能通过验证
Session session = Session.getDefaultInstance(props);
session.setDebug(true);
MimeMessage message = new MimeMessage(session);
MimeMultipart content = new MimeMultipart(); // 创建邮件体对象
if (content == null)
;
MimeBodyPart part = new MimeBodyPart();// 创建文本部分对象
String type = "text/plain ";// 文本类型默认为text/plain
if (text.startsWith( " <html> ") || text.startsWith( " <HTML> "))
type = "text/html ";
// 如果是网页形式的内容，则改变类型为text/html
part.setText(text);
part.setHeader( "Content-Type ", type);
content.addBodyPart(part);
message.setContent(content); // 添加文本至邮件中
message.saveChanges(); // 保存修改
message.setFrom(new InternetAddress(from));
Transport transport = session.getTransport( "smtp ");
for (int j = 0; j < to.length; j++) {
System.out.println(to[j].toString() + "========213=== ");
message.addRecipient(Message.RecipientType.TO,
new InternetAddress(to[j]));
message.setSentDate(new Date());
message.setSubject(subject);
message.setText(text);
// Send message
message.saveChanges();
System.out.println( "==========223==== ");
transport.connect(host, username, password);
System.out.println( "==========225==== ");
transport.sendMessage(message, message.getAllRecipients());
System.out.println( "j= " + j + to.toString() + "*************** ");
transport.close();
}

我用smtp.163.com老是出javax.mail.AuthenticationFailedException.
自己用transport.isConnect()判断连接上了,就是发生这个异常,我也重写了认证类了,代码如下:
Session session = Session.getDefaultInstance(props,new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
PasswordAuthentication pa = new PasswordAuthentication( "lean1252 ", "lean433957 ");
if(pa == null) {
System.out.println( "auth failed... ");
}
return pa;
}
});
可它为什么问题提示认证失败了呢?
