HK2, Spring Bean'leri görmez

Jersey 2 REST hizmetleriyle bir Spring Boot uygulamasına sahibim. Spring Boot, doğru şekilde başlatılıyor gibi görünüyor ve Jersey Spring köprüsüm var ('org.glassfish.jersey.ext: jersey-spring3: 2.22.2'). Buna rağmen, aşağıdaki hata atılır, daha sonra REST denetleyicisi (JAX-RS 2.0) başlatılır ve bir Spring Bean'in içine enjekte edilmesi gerekir.HK2, Spring Bean'leri görmez

org.glassfish.hk2.api.UnsatisfiedDependencyException: There was no object available for injection

Böyle bir hataya neden olabilir?

Fasulye, @Aded ile mevcut ve açıklamalı, bu yüzden sorun değil. Spring Boot varsayılan olarak JSR-330 ek açıklamalarını da tarar.

Düzenleme:

@SpringBootApplication 
public class Application extends SpringBootServletInitializer implements WebApplicationInitializer { 

@Override 
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { 
    return application.sources(Application.class); 
} 
}

'RequestEventLogger' nedir? Spring hizmetlerini Jersey/HK2 kaynaklarına/hizmetlerine enjekte etmenin Spring Boot ile ilgili bir sorun olmadığını söyleyebilirim. Logger'ın gerçekten Spring bağlamında olduğunu nereden biliyorsunuz? 'ApplicationContext' enjekte etmeyi denediniz mi ve bağlamda olup olmadığını görmek için açıkça 'ctx.getBean (RELogger.class)' denmeye çalıştınız mı? –

@peeskillet Haklısınız. Önerdiğini denedim ve Spring de sınıfı bulamıyor. \ @Adlandırılmış bir açıklama ile düşünülen basit bir sınıftır, bu yüzden Spring tarafından alınmalıdır. – Sergey

Logger hangi pakette? Uygulama sınıfıyla aynı pakette ya da bir alt pakette, taramada ( –

Asıl sorun, yorumlarda keşfedilen bir şeydi (orijinal soruda gösterilmedi).

@SpringBootApplication ile (@ComponentScan dahil olmak üzere üç ek açıklama için diğer ad), Spring ile birlikte ücretsiz bileşen taraması alırsınız. Ancak bileşen taraması nasıl çalışır (taranacak paketleri belirtmeksizin), @ComponentScan10 ek açıklamalı sınıfın paketini ve alt paketlerini tarar. Bu nedenle, ile

com.app 
    Application 
com.app.services 
    LoggingService 
com.app.repos 
    UserRepo

kurmak örneğin bütün paketler olsun, bir kök paketinde "uygulaması" sınıfı koymak ve bu paketin alt paketler olarak tüm diğer paketleri olması tavsiye edilir açıklamalı bileşen sınıfları için taranmıştır. Bence OP bu şekilde ayarlamamıştı, bu yüzden Spring bileşenleri taramaya alınmadı.
