Issue
I'm developing a small Spring Boot application for a relative one using a microservice architecture. As multiple service will be sharing some code I created a project named domain to stored all shared classes. I created another project, called configuration, for retrieving parameters from the database. While trying to inject a Repository in a RestController, Spring console is telling it can't find the repository to inject. So far, I've tried to link the source project and add as a module dependency in eclipse. I also added the packages scan in the Application class, but without sucess. On the other hand, external classes are compiling sucessfully. The issue seems to be on Spring Dependecy Injection while importing external eclipse project.
Repository
@Service
public interface ComponentRepository extends JpaRepository<Component, Integer> {
}
Controller
@RestController
public class ConfigurationController {
@Autowired
private ComponentRepository repository;
@GetMapping(path = "/configuration/{component}")
public Optional<Component> getConfiguration(@PathVariable Component component) {
return repository.findById(3);//fixed whitle troubleshooting.
}
}
Application Main Class
@SpringBootApplication(scanBasePackages = { "ofi.marina.configuration", "ofi.marina.domain" })
public class ConfigurationApplication {
public static void main(String[] args) {
SpringApplication.run(ConfigurationApplication.class, args);
}
}

Error Running From Eclipse
Error: Could not find or load main class ofi.marina.configuration.ConfigurationApplication
Caused by: java.lang.ClassNotFoundException: ofi.marina.configuration.ConfigurationApplication
Solution
So, I got it working. As this is a pet project today i continue tinkering with it. So far 3 changes made it:
- Added @ComponentScan to scan the other package
Application Main Class
@SpringBootApplication
@EntityScan(basePackages = {"ofi.marina.domain"})
@ComponentScan(basePackages = {"ofi.marina.domain"})
public class ParametersApplication {
public static void main(String[] args) {
SpringApplication.run(ParametersApplication.class, args);
}
}
Change the repository from @Service to @Component
@Component public interface ComponentRepository extends JpaRepository<ConfigurationComponent, Integer> {
}Removed a class from linked source that was not meant to be included(Is possible that this alone fixed it IDK. Need more tests).
Now Im reorganizing the workspace to avoid this bad designs mistakes. But I hope anybody struggling with a situation like this can find this post.
