Question

我运行了一个tomcat 8.5并在其上部署了我的应用程序。虽然编译一切都很好，但在运行时会发生以下错误：

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。

我已经尝试了几个版本的bouncycastle依赖（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中完成一个项目清理和maven清理。

我还在java.security文件中添加了相应的行：

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

奇怪的是，我可以在某个时候访问ECPublicKeySpec。 E.g：

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

上述工作正常但是：

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我的tomcat在localhost它可以工作。如果我将它部署到远程tomcat它不起作用。

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

Answer 1

就我而言，在CentOS上运行的远程tomcat服务器上没有任何错误。但是，尽管已经导入了相关的maven依赖项，但在运行Windows 10的本地环境中却出现了 NoClassDefFoundError 。幸运的是，除了maven依赖之外，还可以在本地环境中将bcprov-jdk15on-1.55.jar文件复制到 $ java_home / jre / lib / ext 来解决该问题。

NoClassDefFoundError：org / bouncycastle / jce / spec / ECPublicKeySpec即使有bouncycastle可用
