首先我要指出,这绝对是我职业生涯中浪费时间最多的问题。(已经连续两天了,几乎没有任何进展。)每一个所谓的“解决方法”和“应对方案”都无法奏效。因此,我现在被卡住,非常渴望得到帮助。
问题简而言之是:Jersey/HK2 似乎总是在 Spring 已经实例化了我的 bean 后才实例化它们,这说明 jersey-spring3 并未完成其工作,或者至少在我的当前设置下没有(或者我迄今尝试过的 ~50 种不同设置中没有一种能够工作。)
请注意,当我使用空构造函数时,那些资源字段在运行时为 null。
我不明白为什么我的当前设置不起作用,因为我本来就是在仿照这个在线示例去操作。
非常感谢你们能提供帮助!
