java - NoClassDefFoundError : org/bouncycaSTLe/jce/spec/ECPublicKeySpec even though bouncycaSTLe is available

Question

我有一个 tomcat 8.5 正在运行并在上面部署了我的应用程序。虽然编译一切正常，但在运行时出现以下错误:

java.lang.NoClassDefFoundError: org/bouncycastle/jce/spec/ECPublicKeySpec
org.bouncycastle.jcajce.provider.asymmetric.ec.KeyFactorySpi.engineGeneratePublic(Unknown Source)
java.security.KeyFactory.generatePublic(KeyFactory.java:334)
COMPANY.server.impl.BouncyCastleCrypto.decodePublicKey(BouncyCastleCrypto.java:87)
COMPANY.server.impl.U2FServerReferenceImpl.processSignResponse(U2FServerReferenceImpl.java:270)
COMPANY.tools.httpserver.servlets.SignFinishServletImpl.doGet(SignFinishServletImpl.java:41)
javax.servlet.http.HttpServlet.service(HttpServlet.java:635)
javax.servlet.http.HttpServlet.service(HttpServlet.java:742)
org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)

这是我得到的所有堆栈跟踪信息。

我已经尝试了几个版本的 bouncycaSTLe 依赖项(1.58 和 1.50，我使用 maven)bcprov-jdk15on。我查看了生成的 .war 文件，WEB-INF 文件夹包含 jar。我尝试重新下载 maven 依赖项，在 eclipse 中做了一个项目清理和 maven 清理。

我还在 java.security 文件中添加了适当的行:

security.provider.10=org.bouncycastle.jce.provider.BouncyCastleProvider

奇怪的是，我有时可以访问 ECPublicKeySpec。例如:

ECPublicKeySpec ecPublicKeySpec = new ECPublicKeySpec(point,
      new ECParameterSpec(
          curve.getCurve(),
          curve.getG(),
          curve.getN(),
          curve.getH()));
  logger.info(ecPublicKeySpec.toString());

上面的工作正常但是:

KeyFactory.getInstance("ECDSA").generatePublic(ecPublicKeySpec);

或

KeyFactory.getInstance("ECDSA", "BC").generatePublic(ecPublicKeySpec);

这不起作用并产生 NoClassDefFoundError。

编辑:忘记提及:如果我将我的应用程序部署到本地主机上的 tomcat，它就可以工作。如果我将它部署到远程 tomcat，它就无法工作。

EDIT2:mvn dependency:tree -Dverbose -Dincludes=org/bouncycaSTLe/jce/spec/ECPublicKeySpec 的输出:

就我而言，在 CentOS 上运行的远程 tomcat 服务器没有出现任何错误。但是，我在 Windows 10 上运行的本地环境中得到了 NoClassDefFoundError，尽管已经导入了相关的 maven 依赖项。幸运的是，除了maven依赖，将bcprov-jdk15on-1.55.jar文件复制到本地环境的$java_home/jre/lib/ext解决了问题。
