Question

我正在为PEMParser.java类和oracle java 7使用bcpkix-jdk15on-151.jar，

但是在行

PEMParser pemRd = new PEMParser（fRd）;

我得到了以下的例外

我的源代码是：

public static X509Certificate getCertificate() throws IOException {
        String pemfile = "/home/sarang07/keys/key1.crt";
        java.security.cert.X509Certificate cert = null;

        try {
            FileReader fRd = new FileReader(pemfile);
            PEMParser pemRd = new PEMParser(fRd);

            Object o;
            o = pemRd.readPemObject();
            if (o instanceof java.security.cert.X509Certificate)
            {
                cert = (java.security.cert.X509Certificate) o;
            } else {
                throw new IOException("fail to load certificate from file " + pemfile);
            }
        } catch (FileNotFoundException e) {
            throw new IOException("Can't find file " + pemfile);
        }

        return cert;
    }

您可能存在依赖性冲突 - 你在路径中有2个版本的上述jar吗？也许你是在POM文件中添加依赖项，还是在你的构建中添加了另一个jar的veriosn？

最后我从下面的代码片段中得到了解决方案...

public static java.security.cert.X509Certificate getCertificate(String pemfile) throws Exception
{
    java.security.cert.X509Certificate cert = null;
    try {
        FileReader fRd = new FileReader(pemfile);
        final PemReader certReader = new PemReader(fRd);
        final PemObject certAsPemObject = certReader.readPemObject();
        if (!certAsPemObject.getType().equalsIgnoreCase("CERTIFICATE")) {
            throw new Exception("Certificate file does not contain a certificate but a " + certAsPemObject.getType());
        }
        final byte[] x509Data = certAsPemObject.getContent();
        final CertificateFactory fact = CertificateFactory.getInstance("X509");
        cert = (X509Certificate) fact.generateCertificate(new ByteArrayInputStream(x509Data));
        if (!(cert instanceof X509Certificate)) {
            throw new Exception("Certificate file does not contain an X509 certificate");
        }

    } catch (FileNotFoundException e) {
        throw new IOException("Can't find file " + pemfile);
    }
    return cert;
}
