【问题描述】：
我有一个正在运行的 tomcat 8.5 并在其上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。
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，在eclipse中做了一个项目clean和maven clean。
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。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：忘了提一下：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 它将不起作用。
EDIT2：mvn dependency:tree -Dverbose -Dincludes=org/bouncycastle/jce/spec/ECPublicKeySpec 的输出：

【问题讨论】：
-
能否请您运行“mvn 依赖项：tree -Dverbos -Dincludes=yourmissingpackage”并发布结果？有关更多信息，请参阅maven.apache.org/plugins/maven-dependency-plugin/examples/…

遇到完全相同的问题。你找到解决办法了吗？
