Question

我打开这篇文章是因为将Jersey版本从2.25更新到2.27后出现问题。

在更新过程中，Jersey要求我添加jersey-hk2 Maven依赖项。

尽管在泽西岛（Jersey）2.25中，相同的指令也能正常工作，但尝试通过RestClient发送POST请求时却收到ClassCastException，如下所示：

WebTarget webTarget = client.target(resource);
Response response = webTarget.request(MediaType.APPLICATION_JSON)
                             .post(Entity.entity(data, MediaType.APPLICATION_JSON));

这是我收到的整个异常：

我指定，正如网上发布的其他问题所建议的那样，我将Jersey组件的所有版本都匹配到2.27。

任何帮助将不胜感激。

非常感谢！
