[英]javax.mail.MessagingException: Can't send command to SMTP host
嘗試從Java郵件API發送郵件時,我面臨以下異常: javax.mail.MessagingException: Can't send command to SMTP host; nested exception is: javax.net.ssl.SSLHandshakeException: com.ibm.jsse2.util.j: PKIX path building failed: java.security.cert.CertPathBuilderException: PKIXCertPathBuilderImpl could not build a valid CertPath.; internal cause is: java.security.cert.CertPathValidatorException: The certificate issued by CN=Baltimore CyberTrust Root, OU=CyberTrust, O=Baltimore, C=IE is not trusted; internal cause is: java.security.cert.CertPathValidatorException: Certificate chaining error
javax.mail.MessagingException: Can't send command to SMTP host; nested exception is: javax.net.ssl.SSLHandshakeException: com.ibm.jsse2.util.j: PKIX path building failed: java.security.cert.CertPathBuilderException: PKIXCertPathBuilderImpl could not build a valid CertPath.; internal cause is: java.security.cert.CertPathValidatorException: The certificate issued by CN=Baltimore CyberTrust Root, OU=CyberTrust, O=Baltimore, C=IE is not trusted; internal cause is: java.security.cert.CertPathValidatorException: Certificate chaining error
下面是我的Java代碼。 相同的代碼在我的本地系統上運行良好。 當我在tomcat服務器上發布Web應用程序,但是相同的代碼不起作用時。當我在IBM WebSphere Application Server上部署它時。
它顯示了以上異常,
public static void sendMail(String toMailIds,String subject,String htmlMsg){
String[] recipientList = toMailIds.split(",");
InternetAddress[] recipientAddress = new InternetAddress[recipientList.length];
int counter = 0;
for (String recipient1 : recipientList) {
try {
recipientAddress[counter] = new InternetAddress(recipient1.trim());
} catch (AddressException e) {
e.printStackTrace();
}
counter++;
}
// Sender's email ID needs to be mentioned
String from = "abc@xyz.com";
final String username = "abc@xyz.com";//change accordingly
final String password ="password`enter code here`";//change accordingly
String host = "smtp.office365.com";
Properties props = new Properties();
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", host);
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.ssl.trust", host);
// props.put("mail.smtp.ssl.enable", "true");
props.put("mail.smtp.port", "587");
props.put("mail.smtp.debug", "true");
props.put("mail.smtp.user", username);
// Get the Session object.
Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
try {
Transport tr = session.getTransport("smtp");
tr.connect();
System.out.println("Validating email finished");
// Create a default MimeMessage object.
Message message = new MimeMessage(session);
// Set From: header field of the header.
message.setFrom(new InternetAddress(from));
// Set To: header field of the header.
message.setRecipients(Message.RecipientType.TO, recipientAddress);
// Set Subject: header field
message.setSubject(subject);
// HTML TEXT
message.setContent(htmlMsg, "text/html");
// Send message
Transport.send(message);
System.out.println("Sent message successfully....");
} catch (Exception e) {
System.out.println("Exception--------------------"+e);
throw new RuntimeException(e);
}
// TODO Auto-generated constructor stub
}`
看到異常:
The certificate issued by CN=Baltimore CyberTrust Root, OU=CyberTrust, O=Baltimore, C=IE is not trusted;
您使用SSL連接到SMTP服務器。 您必須將SMTP服務器證書放入WebSphere Application Truststore中才能建立連接。 您的Tomcat服務器使用的是不同的JDK,因此使用的是不同的信任庫。
請參閱其他文章,如何在WAS中將簽署者證書添加到信任庫。
第二個考慮因素是您應該在WAS中使用MailSession,而不是對代碼中的所有郵件服務器數據進行硬編碼。 這是在Java EE應用程序中獲取郵件會話的推薦方法。
如果您不想使用完整的WAS進行開發,則應使用WebSphere Liberty概要文件而不是Tomcat進行開發。 它在啟動時間和內存占用方面與Tomcat一樣輕巧,並且WAS中已經包含了庫,因此您不必添加第三方庫。
