我已将我的 openstack4j 版本升级到 3.0.3(从 v2 开始)，但在使用 OKHTTP 连接器和 HTTPCLIENT 连接器从 Tomcat 运行它时出现此错误。

openstack4j v2 没有出现这个问题。
最佳答案
我在我的 Maven 项目中使用版本 3.0.4 时遇到了同样的问题。 将依赖项升级到 3.1.0 解决了它。 以下是包含的工件详细信息:
<dependency>
<groupId>org.pacesys</groupId>
<artifactId>openstack4j</artifactId>
<version>3.1.0</version>
</dependency>
关于java - openstack4j 中的 RestEasyProviderFactory ClassCastException，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41725151/
