java - KeyStore.load() 之后 BufferedInputStream 将不起作用

Question

我的 JavaWS 应用程序将在内部网络中运行，因此它是使用公司自己的证书进行签名的，并且 SSL 证书来自公司的根 CA。因此，由于计算机数量巨大，不太可能在每台计算机上手动导入证书。因此，我使用一个应该自动导入证书的类扩展了我的应用程序，这可以在控制台和 IDE 中运行，但如果应用程序是由 java web start 执行的，则不行:(

代码

        cf = CertificateFactory.getInstance("X.509");

        signCertIn = ClassLoader.class.getResourceAsStream((pack + signCertName + ".cer"));
        sslCertIn = ClassLoader.class.getResourceAsStream((pack + sslCertName) + ".crt");

        File file = new File(new File(System.getProperty("java.home") + SEP + "lib" + SEP + "security"), "cacerts");
        javaCertIn = new FileInputStream(file);

        KeyStore keystore = KeyStore.getInstance(KeyStore.getDefaultType());
        keystore.load(javaCertIn, passphrase);

        javaCertIn.close();

        if (!keystore.containsAlias(signCertName)) {
            bis = new BufferedInputStream(signCertIn); // <<<<<<< Exception thrown here
            while (bis.available() > 0) {
                Certificate cert = cf.generateCertificate(bis);
                keystore.setCertificateEntry(signCertName, cert);
            }
            save = true;
            signCertIn.close();
        }

        if (!keystore.containsAlias(sslCertName)) {
            bis = new BufferedInputStream(sslCertIn);
            while (bis.available() > 0) {
                Certificate cert = cf.generateCertificate(bis);
                keystore.setCertificateEntry(sslCertName, cert);
            }
            save = true;
            sslCertIn.close();
        }

        if (save) {
            OutputStream out = new FileOutputStream(file);
            keystore.store(out, passphrase);
            out.close();
        }

JavaWS 控制台输出

而不是类加载器:

signCertIn = ClassLoader.class.getResourceAsStream((pack + signCertName + ".cer"));

使用类本身:

signCertIn = Certificates.class.getResourceAsStream((pack + signCertName + ".cer"));

为我工作......
