Spring Boot @Repository defined in external jar is not @Autowired

Question

I have created two projects

1. common entity project provides entities and repositories and deployed as a package in GitHub.

2. sample project uses the common entity project package as a dependency

but repositories are not @Autowirded and entities tables are not generated in my second project. project configuration are given below.

the common entity project pom

and I have configured repositories as

@Configuration
@EnableJpaRepositories("com.orbund.galactic.be.common.entities.repository")
@EntityScan(basePackages = {"com.orbund.galactic.be.common.entities.entity"})
public class RepositoryConfig {

}

Any suggestions and help are appreciated. Thanks in advance.

Answer 1

Finally, I solved the issue by importing the first project application to the second project application. Now spring scans entities and repositories classpath and generated beans as necessary.

@SpringBootApplication
@Import(GalacticBeCommonEntitiesApplication.class)
public class GalacticBeCommonSampleApplication {
    public static void main(String[] args) {
        SpringApplication.run(GalacticBeCommonSampleApplication.class, args);
    }
}
