【问题描述】：
我首先要指出的是，总的来说，这是我职业生涯中处理过的最大的时间浪费问题。 （现在已经连续两天了，基本上是 0 进度。）我尝试过的每一个“解决方法”或“解决方案”都没有奏效，所以我被阻止了，非常渴望得到一些帮助。
简而言之，问题是 Jersey/HK2 似乎总是在 Spring 实例化我的 Spring 管理的 bean 之后实例化它们，这告诉我 jersey-spring3 没有做它的工作，或者至少没有用我的当前设置（或迄今为止我尝试过的大约 50 种设置排列中的任何一种。）
请注意，当我使用空构造函数时，这些资源字段在运行时为空。
我不明白为什么我当前的设置不起作用，因为我本质上是 copying this online example
任何帮助都非常感谢！

欢迎来到俱乐部！ :( 在我最初的障碍之后，我正在考虑放弃 Jersey 2.7 并使用 Apache CXF 或 Spring MVC（不幸的是不是 JAX-RS ......）。我想同时我们应该坚持使用 Jersey 1.x??

这篇文章已经很老了，但是通过小道消息告诉我，jersey-spring3 的最新更新解决了这个问题。
