在Java中发送邮件时出现错误 [英] Getting error while sending mail in java
本文介绍了在Java中发送邮件时出现错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我试图使用Java发送邮件.当我将其与GMail的SMTP服务器("smtp.gmail.com")一起使用时，我使用的代码可以正常工作.但是，当我更改代码(smtp_host_name，smtp_port属性和身份验证UserID/Pwd)以通过ISP提供商的SMTP服务器发送电子邮件时，此代码失败.
I was trying to send mail using java. The code i was using worked when I used it with GMail's SMTP server ("smtp.gmail.com"). But when I changed the code (smtp_host_name, smtp_port properties and authentication UserID/Pwd) to send email through the SMTP server of my ISP provider, this code failed.
这是我的代码-
String host = "smtp server host of my isp provider";
Properties props = System.getProperties();
props.put("mail.smtp.host", host);
props.put("mail.debug", "true");
props.put("mail.transport.protocol.", "smtp");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "25");
props.put("mail.smtp.starttls.enable","true");
Session mailSession = Session.getDefaultInstance(props, null);
mailSession.setDebug(sessionDebug);
Message msg = new MimeMessage(mailSession);
msg.setFrom(new InternetAddress(from));
InternetAddress[] address = {new InternetAddress(to)};
msg.setRecipients(Message.RecipientType.TO, address);
msg.setSubject(subject);
msg.setContent(messageText, "text/html");
Transport transport = mailSession.getTransport("smtp");
transport.connect(host, user, pass);
我收到此错误-
javax.mail.MessagingException: Exception reading response;
nested exception is: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?
问题是我可以从系统工作区中的同一代码发送邮件.但是，在我将war文件上传到主机后，出现了以上错误.我认为我禁用了SSL，但仍然收到此错误.有人可以帮忙吗?紧急...
The problem is i am able to send mails from the same code from my system workspace. But after i upload the war file to host, i get the above error. I think i disabled SSL but still getting this error. Can someone please help. Its urgent...
我按照下面给出的步骤进行操作，但是仍然遇到相同的错误. 现在这是我的代码-
I followed the steps given below but still i am getting the same error. Here is my code now-
String host = "mail.myweb.com", user = emailUser, pass = emailPasswd;
String to = emailID;
String from = emailFrom;
String subject = subj;
String messageText = message;
boolean sessionDebug = true;
Properties props = System.getProperties();
props.put("mail.smtp.host", host);
props.put("mail.debug", "true");
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "25");
Session mailSession = Session.getDefaultInstance(props, null);
mailSession.setDebug(sessionDebug);
Message msg = new MimeMessage(mailSession);
msg.setFrom(new InternetAddress(from));
InternetAddress[] address = {new InternetAddress(to)};
msg.setRecipients(Message.RecipientType.TO, address);
msg.setSubject(subject);
msg.setContent(messageText, "text/html");
Transport transport = mailSession.getTransport("smtp");
transport.connect(host, user, pass);
try {
transport.sendMessage(msg, msg.getAllRecipients());
}
catch (Exception e) {
System.out.println("Error" + e.getMessage());
}
transport.close();
}
这是完整的堆栈跟踪

推荐答案
您好，尝试为非SSL SMTP连接添加以下属性
Hi try to add following properties for non ssl smtp connection
props.put("mail.smtp.starttls.enable","false");
props.put("mail.smtp.socketFactory.port", "25");
props.put("mail.smtp.socketFactory.class", "");
props.put("mail.smtp.socketFactory.fallback", "false");
例如 ssl 连接属性是
Properties props = new Properties();
props.put("mail.smtp.username", "email@gmail.com");
props.put("mail.smtp.password", "password");
props.put("mail.smtp.protocol", "smtp");
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.socketFactory.port", "587");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");
非ssl 属性是
Properties props = new Properties();
props.put("mail.smtp.user", "email@mydomain.com");
props.put("mail.smtp.password", "password");
props.put("mail.smtp.protocol", "smtp");
props.put("mail.smtp.host", "smtp.mydomain.com");
props.put("mail.smtp.port", "25");
props.put("mail.smtp.starttls.enable","false");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.socketFactory.port", "25");
props.put("mail.smtp.socketFactory.class", "");
props.put("mail.smtp.socketFactory.fallback", "false");
