Java KeyClope错误：无法识别的字段“；访问“U令牌”；

我正在使用KeyClope来保护我的rest API，我遵循以下步骤以编程方式添加用户，但我收到了错误消息：

我在网上搜索了一下，发现了这个问题，但它不起作用，我还发现了一个讨论（我需要更多的声誉来发布链接：http://lists.jboss.org/pipermail/keydape user/2014-11/001120.html），它解释了问题的原因，但我没有找到解决方案。 任何人都可以提供帮助。

KeyClope管理客户端（从1.9.0版开始）支持现成的

resteasy-jackson2-provider

JSON提供程序，这就解决了问题

---

在pom中使用它代替resteasy jackson provider。

感谢您的回复，但就我而言，我使用的是Key斗篷1.6.0和jboss wildfly 9。所以我认为我应该使用

resteasy-jackson-provider

你是对的，我发现一些依赖项使用

resteasy-jackson-2-provider

，所以我使用jboss-deployment-structure.xml将其排除在外，我使用

resteasy-jackson-provider

而不是两年后，仍然有不推荐的例子提到resteasy jackson提供商毒害谷歌结果，这个答案仍然是一个救命稻草。
