jersey-spring3 instanciación del frijol manejado por Spring (nulo!)
Primero quiero señalar que este es, en general, el mayor problema en términos de tiempo perdido que he tratado en mi carrera. (Durante dos días seguidos ahora con un progreso esencialmente 0). Cada "solución alternativa" o "solución" que he intentado no ha funcionado, por lo que estoy bloqueado y bastante desesperado por algo de ayuda.
El problema en pocas palabras es que Jersey / HK2 siempre parece crear una instancia de mis beans administrados por Spring DESPUÉS de que Spring ya haya creado una instancia de ellos, lo que me dice quejersey-spring3 no está haciendo su trabajo, o al menos no con mi configuración actual (o cualquiera de las ~ 50 permutaciones de configuraciones que he probado hasta ahora).
Tenga en cuenta que cuando uso un constructor vacío, esos campos de recursos son nulos en tiempo de ejecución.
No entiendo por qué mi configuración actual no funciona, ya que soy esencialmentecopiando este ejemplo en línea
Cualquier ayuda es más que apreciada !!
