java.security.cert.CertificateParsingException：无效的DER编码证书数据

Question

当我尝试将证书导入java密钥库时，我收到以下异常。

“java.security.cert.CertificateParsingException：DER编码的证书数据无效”

FileInputStream fis = new FileInputStream(filename);
BufferedInputStream bis = new BufferedInputStream(fis);

java.security.cert.CertificateFactory cf = java.security.cert.CertificateFactory
            .getInstance("X.509");
while (bis.available() > 0) {
    Certificate cert = cf.generateCertificate(bis);

    if (cert instanceof X509Certificate) {
            certFx.addCertificate("vel", (X509Certificate) cert, true);
    }
}

任何帮助将不胜感激！

确保您的证书以-----BEGIN CERTIFICATE-----开头，并以-----END CERTIFICATE-----结尾。您的证书应如下所示：

-----BEGIN CERTIFICATE-----
