由于循环依赖，Tomcat 容器无法启动 [重复]答案

【问题标题】：Tomcat container failed to start due to cyclic dependency [duplicate]由于循环依赖，Tomcat 容器无法启动 [重复]

【问题描述】：

我在启动 tomcat 时遇到错误。由于循环依赖，tomcat 容器无法启动并在日志中显示 StackOverflowError。我尝试将 -Xss 值设置为 4M 但它没有帮助。无法弄清楚哪个是给出依赖问题的确切 jar。我正在使用 tomcat 7.0.40。

有人可以帮忙吗？

【问题讨论】：

这是由bouncycastle中的非法组件扫描引起的
请看This Answer
@Eddie - 我检查了 bouncycastle 的 maven 依赖树。有 2 个工件下载相同的 bouncycastle jar 但版本不同。猜猜这就是问题所在。在一个依赖项中排除相同的内容后，tomcat 不会给出该错误。感谢您的帮助...

【解决方案1】：

可能在应用程序上添加了相同库的两个版本。就我而言，它是 bcprov-ext-jdk15on-1.69.jar 和 bcprov-jdk16-143.jar。一旦我删除了 bcprov-jdk16-143.jar，问题就解决了。
