【问题标题】：Could not load [org.bouncycastle.jcajce.provider.digest.GOST3411$Mappings]无法加载 [org.bouncycastle.jcajce.provider.digest.GOST3411$Mappings]

【问题描述】：

我正在使用 tomcat8 服务器，.bouncycastle 进行文档签名。一个战争文件已经在我的服务器上运行。当我为我的第二个项目部署了新的战争文件时，出现异常。

我已经点击并试用了 stackoverflow 上的每个链接，但没有运气

org.apache.catalina.loader.WebappClassLoaderBase.checkStateForResourceLoading 非法访问：此 Web 应用程序实例已停止已经。不能加载 [org.bouncycastle.jcajce.provider.digest.GOST3411$Mappings]。这抛出以下堆栈跟踪以用于调试目的以及尝试终止导致非法访问的线程。 java.lang.IllegalStateException：非法访问：此 Web 应用程序实例已经停止。无法加载

 public static void xmlSigner(File xmlFile,String pfxFilePath){
    try{
            File pfxFile=new File(pfxFilePath);
            Security.addProvider(new BouncyCastleProvider());
            log.info("Above key store ");
            KeyStore keyStore = KeyStore.getInstance("pkcs12", "BC");
            log.info("below key store ");
            keyStore.load(new FileInputStream(pfxFile),password.toCharArray());
            log.info("load pfx file key store ");
            String alias = (String) keyStore.aliases().nextElement();
            PrivateKey privateKey = (PrivateKey) keyStore.getKey(alias, password.toCharArray());
            Certificate[] certificateChain = keyStore.getCertificateChain(alias);
            X509Certificate publickeyCertificate = (X509Certificate) certificateChain[certificateChain.length - 1];
            //log.info("privateKey : " + privateKey);
            //log.info("xmlSigner : " + xmlFile);
            log.info("SignerClient - Above Sign and Zip");
            SignerUtil.signAndzipFile(xmlFile, privateKey, publickeyCertificate);
            log.info("Successfully Signed");
        }
        catch(Exception xmlSignerException){
            log.error("xmlSigner : ", xmlSignerException);
            xmlSignerException.printStackTrace();

        }

   }

我在下面一行遇到异常

KeyStore keyStore = KeyStore.getInstance("pkcs12", "BC");

也许这些链接可以帮助你stackoverflow.com/questions/5386934/…，stackoverflow.com/questions/15521270/…
@AbdouRayes：好的
@AbdouRayes ：没有得到预期的答案，我已经尝试了所有给定的答案
很多关于服务器重启问题的答案已经解决。实际上我正在开发预生产环境。所以我想修复我当前的环境，因为我无权重新启动生产环境。
BouncyCastle 类的类加载问题的最常见原因是类路径中有多个 BC jar 副本，通常是不同的版本。请检查。另请说明您使用的 BC 版本、您使用的特定 BC 罐子以及这些罐子的位置。

我也遇到了同样的问题，Tomcat重启解决了。

感谢您的建议和回答??

【解决方案2】：

请首先检查 org.bouncycastle 是否有多个版本。保留一个版本，如果使用tomcat，重启tomcat。
