jersey-spring3 instantiating Bean gerenciado pela mola (null!)
Primeiramente quero ressaltar que este é, de modo geral, o maior problema em termos de tempo desperdiçado com o qual já trabalhei na minha carreira. (Ao longo de dois dias seguidos, com um progresso de 0 essencialmente.) Cada tentativa ou solução que tentei não funcionou, por isso estou bloqueado e bastante desesperado por alguma ajuda.
O problema em poucas palavras é que Jersey / HK2 parece sempre instanciar meus beans gerenciados pelo Spring APÓS eles já terem sido instanciados pelo Spring, o que me diz quejersey-spring3 não está fazendo o seu trabalho, ou pelo menos não com a minha configuração atual (ou qualquer uma das ~ 50 permutações de configurações que eu tentei até agora.)
Observe que quando eu uso um construtor vazio, esses campos de recursos são nulos em tempo de execução.
Eu não entendo porque minha configuração atual não funciona como eu sou essencialmentecopiando este exemplo online
Qualquer ajuda é mais do que apreciada !!
