我正在處理用戶在發生特定觸發時收到電子郵件的應用程序。
這是我用來發送電子郵件的功能：
public static void sendEmail(String host, String port, String useSSL, String useTLS, String useAuth, String user, String password, String subject, String content, String type, String recipients)
throws NoSuchProviderException, AddressException, MessagingException {
final Properties props = new Properties();
props.setProperty("mail.transport.protocol", "smtp");
props.setProperty("mail.smtp.host", host);
props.setProperty("mail.smtp.port", port);
if (useSSL != null && !useSSL.equals("false") && useSSL.equals("true")) {
props.setProperty("mail.smtp.ssl.enable", useSSL);
props.setProperty("mail.smtp.socketFactory.class",
"javax.net.ssl.SSLSocketFactory");
props.setProperty("mail.smtp.socketFactory.port", port);
}
if (useTLS != null && !useTLS.equals("false") && useTLS.equals("true")) {
props.setProperty("mail.smtp.starttls.enable", useTLS);
props.setProperty("mail.smtp.socketFactory.fallback", "true");
}
props.setProperty("mail.smtp.auth", useAuth);
props.setProperty("mail.from", user);
props.setProperty("mail.smtp.user", user);
props.setProperty("mail.password", password);
Session mailSession = Session.getDefaultInstance(props, new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(props.getProperty("mail.smtp.user"), props
.getProperty("mail.password"));
}
});
Transport transport = mailSession.getTransport();
MimeMessage message = new MimeMessage(mailSession);
message.setHeader("Subject", subject);
message.setContent(content, type);
StringTokenizer tokenizer = new StringTokenizer(recipients, ";");
while (tokenizer.hasMoreTokens()) {
String recipient = tokenizer.nextToken();
message.addRecipient(Message.RecipientType.TO,
new InternetAddress(recipient));
}
transport.connect();
transport.sendMessage(message, message.getRecipients(Message.RecipientType.TO));
transport.close();
奇的是，每當我試圖運行與主要方法上面的代碼它會發送電子郵件兩種SSL和TLS協議成功。
public static void main(String args[])
{
try {
Notifier.sendEmail("smtp.gmail.com", "587", "false", "true", "true","[email protected]", "testpassword", "CHECKING SETTINGS", "CHECKING EMAIL FUNCTIONALITY", "text/html", "[email protected]");
} catch (Exception ex) {
ex.printStackTrace();
}
}
但是，只要我嘗試通過我的web應用程序運行相同的代碼，它就會失敗。
通過SSL發送它拋出這個錯誤：
com.sun.mail.smtp.SMTPSendFailedException: 530-5.5.1 Authentication Required. Learn more at

jvm 1 | at com.sun.mail.smtp.SMTPTransport.issueSendCommand(SMTPTransport.java:2057)
通過TLS發送它拋出這個錯誤：
javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 587;
jvm 1 | nested exception is:
jvm 1 | javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?
jvm 1 | at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1934)
任何形式的幫助表示讚賞。
EDIT1：
下面是從前端TPL文件
<div class="label1"><h3 class="label">Host:</h3></div>
<div class="field1"><input type="text" class="input1" name="host" size="20" value="$HOST$"></div>
<div class="port"><h3 class="label">Port:</h3></div>
<div class="fieldport"><input type="text" class="fieldport" name="port" size="5" value="$PORT$"></div>
<div class="ssl">
<input type="radio" name="sslEnable" value="$SSLENABLE$">
Enable SSL?
</div>
<div class="tls">
<input type="radio" name="tlsEnable" value="$TLSENABLE$">
Enable TLS?
</div>
<div class="auth">
<input type="checkbox" name="auth"$AUTH$>
Enable Authentication?
</div>
<div class="label2"><h3 class="label">User:</h3></div>
<div class="field2"><input type="text" class="input1" name="user" size="20" value="$USER$"></div>
<div class="label3"><h3 class="label">Password:</h3></div>
<div class="field3"><input type="password" class="input1" name="password" size="20" value="$PASSWORD$"></div>
<div class="label4"><h3 class="label">Recipient(s):</h3></div>
<div class="field4"><input type="text" class="input1" name="recipients" size="50" value="$RECIPIENTS$"></div>
的數值會保存在一個配置文件，該文件是這樣的：
host=smtp.gmail.com
port=587
ssl=false
tls=true
auth=true
[email protected]
password=O0UbYboDfVFRaiA=
[email protected]
trigger1=false
attempt=0
trigger2=false
percent=5
anyOrAll=ANY
trigger3=true
format=HTML
trigger4=true
trigger5=true
EDIT2：
public static void sendEmail(String message)
throws NoSuchProviderException, AddressException, MessagingException
{
if (message == null || message.trim().equals("")) return;
StringBuffer content = new StringBuffer();
content.append(getHeader());
content.append(message);
content.append(getFooter());
String format = NotifyProps.getFormat();
String type = "text/plain";
if (format.equals(NotifyProps.HTML)) type = "text/html";
sendEmail(NotifyProps.getHost(), NotifyProps.getPort(), Boolean.toString(NotifyProps.getUseAuth()), Boolean.toString(NotifyProps.getUseSSL()), Boolean.toString(NotifyProps.getUseTLS()),NotifyProps.getUser(), NotifyProps.getPassword(),
"Transaction Processor Auto Notification", content.toString(), type,
NotifyProps.getRecipients())
}
這是用於設置和獲取屬性類：
謝謝。
令我驚訝的是，你說它在命令行測試中起作用。即使使用TLS，您應該將'mail.smtp.socketFactory.class'設置爲'javax.net.ssl.SSLSocketFactory'，而不僅僅是SSL。 但與此無關，我建議你使用Yoda條件來檢查字符串常量，如'「true」.equals（sslStr）'。它是無效的，並且沒有混亂。 – coladict
