Repo-Bean kann nicht automatisch ausgelöst werden

Question

Ich verwende SpringBoot 1.4.0.RELEASE. Mein Projekt Strukturbaum sieht wie folgt aus

com 
└── projectname 
    ├── Application.java 
    ├── api 
    │   ├── authentication 
    │   │   ├── AuthenticatedUser.java 
    │   │   ├── AuthenticationRequest.java 
    │   │   ├── AuthenticationToken.java 
    │   │   ├── AuthenticationTokenFilter.java 
    │   │   ├── AuthenticationTokenUtil.java 
    │   │   ├── JwtAuthenticationEntryPoint.java 
    │   │   └── PasswordRequest.java 
    │   ├── common 
    │   │   └── CommonClasses.java 
    │   ├── config 
    │   │   ├── DbConfiguration.java 
    │   │   ├── SimpleCORSFilter.java 
    │   │   └── WebSecurityConfig.java 
    │   └── service 
    │      └── AuthenticationService.java 
    └── persistence 
     ├── domain 
     │   └── User.java 
     ├── repository 
     │   └── UserRepo.java 
     └── service 
      └── UserService.java 

Hier ist, wie ich konfiguriert habe meine Application.java Klasse für Spring

Application.java

@SpringBootApplication 
@ComponentScan 
@EnableAutoConfiguration 
@EnableSwagger2 
@Log 
public class Application extends SpringBootServletInitializer { 
    private static Class<Application> app = Application.class; 

    public static void main(String[] args) throws Exception { 
     SpringApplication.run(app, args); 
    } 

    @Override 
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { 
     return application.sources(app); 
    } 
    //other methods to configure swagger and security 
} 

Hier ist, wie UserRepo sieht aus wie

public interface UserRepo extends MongoRepository<User, String> { 
    User findById(String emailId); 

    List<User> findAll(); 

} 

und das ist, wie ich meine UserService.java

@Service 
public class UserService { 
    @Autowired 
    private UserRepo userRepo; 
    // methods to fetch data 
    } 

nun umgesetzt haben, wenn ich versuche, userService in authenticationService für die Anmeldung zu verwenden, wird Anwendungsausnahme zu werfen, dass es nicht userRepo Bohne finden konnten. Was ich hier fehlt, ist hier die Ausnahme

Answer 1

Sie wahrscheinlich Spring Data MongoDB-Konfiguration oder mit falschen basePackages, so etwas fügen vergessen:

@Configuration 
@EnableMongoRepositories(basePackages = "com.projectname.persistence") 
class ApplicationConfig extends AbstractMongoConfiguration { 
//... 
}
