我有一个java编译包与https服务器在网上说话。运行编译会出现以下异常:
javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?
at com.sun.net.ssl.internal.ssl.InputRecord.handleUnknownRecord(Unknown Source)
at com.sun.net.ssl.internal.ssl.InputRecord.read(Unknown Source)
at com.sun.net.ssl.internal.ssl.SSLSocketImpl.readRecord(Unknown Source)
at com.sun.net.ssl.internal.ssl.SSLSocketImpl.performInitialHandshake(Unknown Source)
at com.sun.net.ssl.internal.ssl.SSLSocketImpl.startHandshake(Unknown Source)

at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(Unknown Source)
at sun.net.www.protocol.https.HttpsURLConnectionImpl.connect(Unknown Source)
我认为这是因为与客户端机器建立的连接不安全。是否有任何方法配置本地机器或端口以连接到远程https服务器?
它现在对我有效，我已经更改了我的谷歌账户的设置如下:
System.out.println("Start");
final String username = "myemail@gmail.com";
final String password = "************";
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "465");
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
try {
Transport transport=session.getTransport();
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("myemail@gmail.com"));//formBean.getString("fromEmail")
message.setRecipients(Message.RecipientType.TO,InternetAddress.parse("myemail@gmail.com"));
message.setSubject("subject");//formBean.getString(
message.setText("mailBody");
transport.connect();
transport.send(message, InternetAddress.parse("myemail@gmail.com"));//(message);
System.out.println("Done");
} catch (MessagingException e) {
System.out.println("e="+e);
e.printStackTrace();
throw new RuntimeException(e);
}
虽然我在同一篇文章的这个链接中运行程序时启用了SSL和TSL。我花了很多时间，但我意识到并发现了这个联系。
并在谷歌中完成以下2步和设置控制。：
禁用两步验证(密码和OTP)
允许访问不安全的应用程序(允许不安全的应用程序:
上)。
现在我可以用上面的程序发送邮件了。
我也遇到了同样的问题，通过在系统属性中设置“proxyUser”和“proxyPassword”来解决。
System.setProperty("http.proxyUser", PROXY_USER);
System.setProperty("http.proxyPassword", PROXY_PASSWORD);
连同“proxyHost”和“proxyPort”
System.setProperty("http.proxyHost", PROXY_ADDRESS);
System.setProperty("http.proxyPort", PROXY_PORT);
希望它能起作用。
javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?
您应该有一个本地SMTP域名，该域名将与邮件服务器联系并建立一个新的连接，您还应该在下面的编程中更改SSL属性
javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection
props.put("mail.smtp.socketFactory.fallback", "true"); // Should be true
