用java发送邮件时发生错误

2012-04-22 91 views

我试图用java发送邮件。当我使用GMail的SMTP服务器（“smtp.gmail.com”）时，我使用的代码正常工作。但是，当我更改代码（smtp_host_name，smtp_port属性和身份验证用户名/密码）以通过我的ISP提供商的SMTP服务器发送电子邮件时，此代码失败。用java发送邮件时发生错误

这里是我的代码 -

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);

，我得到这个错误 -

javax.mail.MessagingException: Exception reading response; 
nested exception is: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?

的问题是，我能够从相同的代码从我的系统工作区中发送邮件。但是，我上传战争文件到主机后，我得到了上述错误。我想我禁用SSL，但仍然得到这个错误。有人可以请帮助。它的迫切...

我按照下面给出的步骤，但我仍然得到相同的错误。 这里是我的代码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(); 
}

您试图在非SSL连接上使用SSL，正如错误所述。你的最后一个属性明确地做到了 – 2012-04-22 15:32:39

我删除了最后一个属性，但仍然不能正常工作.... – 2012-04-22 17:09:15

此行

props.put("mail.smtp.starttls.enable","true");

被启用此连接上的SSL;让它变成虚假的，或者只是把它拿出来。

此外，在该属性名称的末尾点是可疑的，虽然可能无毒：

props.put("mail.transport.protocol.", "smtp");

你需要获得一个Transport对象与smtps协议。使用版本1.4.1或更高版本的Java Mail API。
我不确定这是否在早期版本中受支持。
每个smtp.jar和imap.jar包含名为javamail.providers具有以下项目的资源文件：

# JavaMail SMTP provider Sun Microsystems, Inc 
protocol=smtp; type=transport; class=com.sun.mail.smtp.SMTPTransport; vendor=Sun Microsystems, Inc; 
protocol=smtps; type=transport; class=com.sun.mail.smtp.SMTPSSLTransport; vendor=Sun Microsystems, Inc; 

# JavaMail IMAP provider Sun Microsystems, Inc 
protocol=imap; type=store; class=com.sun.mail.imap.IMAPStore; vendor=Sun Microsystems, Inc; 
protocol=imaps; type=store; class=com.sun.mail.imap.IMAPSSLStore; vendor=Sun Microsystems, Inc;

当你创建一个邮件会话对象，这些资源被加载。 DEBUG跟踪如下：

DEBUG: JavaMail version 1.4.5 
DEBUG: URL jar:file:/E:/Ravi/work/eclipse-workspace/temp/WebContent/WEB-INF/lib/smtp.jar!/META-INF/javamail.providers 
DEBUG: successfully loaded resource: jar:file:/E:/Ravi/work/eclipse-workspace/temp/WebContent/WEB-INF/lib/smtp.jar!/META-INF/javamail.providers 
DEBUG: Tables of loaded providers 
DEBUG: Providers Listed By Class Name: {com.sun.mail.smtp.SMTPSSLTransport=javax.mail.Provider[TRANSPORT,smtps,com.sun.mail.smtp.SMTPSSLTransport,Sun Microsystems, Inc], com.sun.mail.smtp.SMTPTransport=javax.mail.Provider[TRANSPORT,smtp,com.sun.mail.smtp.SMTPTransport,Sun Microsystems, Inc], com.sun.mail.imap.IMAPSSLStore=javax.mail.Provider[STORE,imaps,com.sun.mail.imap.IMAPSSLStore,Sun Microsystems, Inc], com.sun.mail.pop3.POP3SSLStore=javax.mail.Provider[STORE,pop3s,com.sun.mail.pop3.POP3SSLStore,Sun Microsystems, Inc], com.sun.mail.imap.IMAPStore=javax.mail.Provider[STORE,imap,com.sun.mail.imap.IMAPStore,Sun Microsystems, Inc], com.sun.mail.pop3.POP3Store=javax.mail.Provider[STORE,pop3,com.sun.mail.pop3.POP3Store,Sun Microsy stems, Inc]} 
DEBUG: Providers Listed By Protocol: {imaps=javax.mail.Provider[STORE,imaps,com.sun.mail.imap.IMAPSSLStore,Sun Microsystems, Inc], imap=javax.mail.Provider[STORE,imap,com.sun.mail.imap.IMAPStore,Sun Microsystems, Inc], smtps=javax.mail.Provider[TRANSPORT,smtps,com.sun.mail.smtp.SMTPSSLTransport,Sun Microsystems, Inc], pop3=javax.mail.Provider[STORE,pop3,com.sun.mail.pop3.POP3Store,Sun Microsy stems, Inc], smtp=javax.mail.Provider[TRANSPORT,smtp,com.sun.mail.smtp.SMTPTransport,Sun Microsystems, Inc], pop3s=javax.mail.Provider[STORE,pop3s,com.sun.mail.pop3.POP3SSLStore,Sun Microsystems, Inc]}

我们需要得到的com.sun.mail.smtp.SMTPSSLTransport实例使用smtps协议。

Transport transport = mailSession.getTransport("smtps");

由于资源具有用于这个协议定义的提供商，而没有任何异常生成Transport对象。

DEBUG: getProvider() returning javax.mail.Provider[TRANSPORT,smtps,com.sun.mail.smtp.SMTPSSLTransport,Sun Microsystems, Inc]

如果你所有的输入都是正确的，你会得到成功。DEBUG在样品上执行如下所示：

DEBUG SMTP: trying to connect to host "smtp.gmail.com", port 465, isSSL true 
220 mx.google.com ESMTP d2sm12188996pbw.39

您好尝试非SSL SMTP连接

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");

例如添加以下属性SSL连接属性是

Properties props = new Properties(); 
    props.put("mail.smtp.username", "[email protected]"); 
    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 protected]"); 
    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");
