我正在使用如下代码中的代码用户名用户名用户名和密码给出了我要发送邮件的邮件密码

Properties props = System.getProperties(); 
props.put("mail.smtp.starttls.enable", "true"); 
props.put("mail.smtp.host", host); 
props.setProperty("mail.transport.protocol", "smtps");
props.put("mail.smtp.user", userid); 
props.put("mail.smtp.password", password); 
props.put("mail.smtp.port", "465"); 
props.put("mail.smtps.auth", "true"); 
Session session = Session.getDefaultInstance(props, null); 
MimeMessage message = new MimeMessage(session); 
InternetAddress fromAddress = null;
InternetAddress toAddress = null;

try {
fromAddress = new InternetAddress(from);
toAddress = new InternetAddress(to);
} catch (AddressException e) {

e.printStackTrace();
}

message.setFrom(fromAddress);
message.setRecipient(RecipientType.TO, toAddress);
message.setSubject(subject);
message.setText(text); 

//SMTPSSLTransport transport =(SMTPSSLTransport)session.getTransport("smtps");

Transport transport = session.getTransport("smtps"); 
transport.connect(host, userid, password); 
transport.sendMessage(message, message.getAllRecipients()); 
transport.close();

但它给了我这样的错误

 javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 465;
  nested exception is:
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1972)
at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:642)

任何人都可以建议我的代码有什么问题.....提前谢谢你.....

Properties props = new Properties();
            props.put("mail.smtp.auth", "true");
            props.put("mail.smtp.starttls.enable", "true");
            props.put("mail.smtp.host", "smtp.gmail.com");
            props.put("mail.smtp.port", "587");

这是我用来使用 gmail 帐户成功发送电子邮件的属性设置。然后，您可以使用以下方法创建会话：

Session session = Session.getDefaultInstance(props, new javax.mail.Authenticator() {
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication(emailAddress, password);
                }
              });

这是一种略有不同的方法，但它在我使用的代码中有效。
