java - ClassCastException 原因

In lại 作者：行者123 更新时间：2023-12-02 11:05:50

我正在获取 ClassCastException 。这两个类来自不同的 jar，但是JettyContinuationProviderFactory 正在实现 ContinuationProviderFactory 类。

我在 Tomcat 中制作了 SOAP Web 服务的演示，运行良好。但是这些错误是在 JBOSS EAP 6 的情况下生成的。任何人都可以提供帮助吗？

这可能是一个类加载问题，您的类路径上可能有 2 个不同的 jar，它们都包含 ContinuationProviderFactory.class.

代码的不同部分现在可能使用该接口(interface)的不同版本，因此您的 JettyContinuationProviderFactory 现在正在实现一个版本，但您传递 JettyContinuationProviderFactory 实例的方法to 期待其他接口(interface)。

这会产生无法通过强制转换解决的类型冲突，因此会出现此异常。尽管这看起来很愚蠢，但从 JVM 类加载的角度来看，它非常有意义。

它在 Tomcat 上工作的原因是你的类路径可能恰好更干净。解决方案是调查类路径上的哪些 jar 正在提供 ContinuationProviderFactory 并消除重复项。
