我只是尝试按照this教程来为我的Web服务实现基于令牌的身份验证，并且刚刚完成了“保护REST端点”步骤，但是现在在调用端点时总是遇到AbstractMethodError。
我已经在another question上阅读到该问题似乎是由于库的兼容性问题而出现的，但是答案包括我未使用的Maven，因此我尝试手动交换库，但没有解决，我不断出现相同或不同的错误。
我必须删除哪些库，并且必须保留哪些库？
控制台输出：

最佳答案
您可能已解决问题，但实际问题是uri方法是JAX-RS规范的2.0版中UriBuilder中的抽象方法。
您正在尝试将JAX-RS 2.0与Jersey 1.*一起使用。相反，您需要使用实现Jersey 2.*并包含JAX-RS 2.0方法的实现的uri。
