我的发送邮件去年正在运行，但我想知道它为什么现在给我一个CertPathValidatorException
更新：我尝试使用Mkyong的教程（TLS）+覆盖socketfactory。但它给了我一个不同的例外。
筹码：

这是我的新sendEmail（）：
private boolean sendEmail(String from, String to, String subject, String body){
final String username = activity.getResources().getString(R.string.feedback_sender_email);
final String password = activity.getResources().getString(R.string.feedback_sender_password);
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");
props.put("mail.smtp.socketFactory.class",
"com.sblive.connector.MySSLSocketFactory");
Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(to));
message.setSubject(subject);
message.setText(body);
Transport.send(message);
return true;
} catch (MessagingException e) {
e.printStackTrace();
return false;
}
答案 0 :(得分：0)
您不信任服务器证书。首先要注意那里
Send Email in Service (without prompting user)
它对我有用。
其他解决方案：
将它导入您的信任库并使用javax.net.ssl.trustStore *系统属性指定信任stire（全局jre应该没问题）。
props.put("mail.transport.protocol", "smtps");
props.put("mail.smtps.ssl.checkserveridentity", "false");
props.put("mail.smtps.ssl.trust", "*");
或 how to ignore server cert error in javamail
使用
props.put("mail.smtp.socketFactory.class", "MySSLSocketFactory ");
和
public class MySSLSocketFactory extends SSLSocketFactory {
SSLContext sslContext = SSLContext.getInstance("TLS");
public MySSLSocketFactory(KeyStore truststore) throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException {
super(truststore);
TrustManager tm = new X509TrustManager() {
public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
sslContext.init(null, new TrustManager[] { tm }, null);
}
@Override
public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException, UnknownHostException {
return sslContext.getSocketFactory().createSocket(socket, host, port, autoClose);
}
@Override
public Socket createSocket() throws IOException {
return sslContext.getSocketFactory().createSocket();
}
}
