我正在将 Tomcat Web 应用程序从 Tomcat 9.0.78 升级到 10.0.14，并将所有导入从 javax.servelet 命名空间移至 jakarta.servelt 命名空间，并且还升级了 hibernate。
虽然我已经能够解决大多数问题，但我遇到了在 /tomcat/logs/localhost.2023-09-12.log 中看到的以下错误
我尝试从 tomcat/lib 中删除 jar，例如 jakarta.inject-2.6.1.jar 和 jakarta.inject-api-2.0.0.jar，但这些会导致类未找到异常。
我认为该错误意味着两个不同的地方正在尝试实例化 org.glassfish.jersey.inject.hk2.RequestContext 但我不知道在哪里。
编辑：
查看源代码后，org.glassfish.jersey.inject.hk2.RequestContext 被创建两次并不是问题，而是它没有实现 jakarta.singleton 空间。
根据 jan.supol 的评论，所有球衣罐都是 3.0.2 版本，其中一个包含有问题的类。

我通过根据我的 Tomcat 版本定位所有 jar 来修复此问题。我发现我的 tomcat 版本使用 Jakarta ee 9，并且我的所有第三方 jar 都围绕它。
具体来说，就我而言，罪魁祸首是 hk2 jar 的版本。
