I am encountering a baffling @Autowired issue, which only occurred after I added a dependency to one of my own projects.
Here is the situation:
I am extending a service, which has autowired repositories. Here's the simplified version:
package com.opt.custom.domain;
import com.opt.repo.RepositoryOne;
import com.opt.repo.RepositoryTwo;
@Primary
@Service("CustomDomainServiceImpl")
public class CustomDomainServiceImpl extends DomainServiceImpl {
private RepositoryOne repo1;
private RepositorTwo repo2;
@Autowired
public CustomDomainServiceImpl(RepositoryOne repo1
, RepositorTwo repo2) {
super(repo1, repo2);
}
....
}
This has been working fine - the @Autowired tags grab the repositories fine, whether or not I include them as attributes, as I don't use them except to feed into the parent service.
However, I have created another service (with its own service, repositories, etc.). When I add this new service as a dependency of the above project (in the POM file), the @Autowired annotations in the above code stop working, even if I don't reference any of the services, repos, etc. in this class. Specifically, the error is:
Parameter 0 of constructor in com.opt.custom.domain.CustomDomainServiceImpl required a bean of type 'com.opt.repo.RepositoryOne' that could not be found.
Action:
Consider defining a bean of type 'com.opt.repo.RepositoryOne' in your configuration.
I don't know how simply adding a dependency (while not using anything from it) can cause this issue.
I have tried adding a @ComponentScan to the above class:
@ComponentScan(basePackages = {"com.opt.repo"})
But this has not helped.
If it helps, this is the top-level class in the Maven project that I am adding as a dependency:
package com.opt.new.service;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
@SpringBootApplication
@EntityScan(basePackages = { "com.someotherpackage.persistence.*" })
public class PersistenceClasses {
public static void main(String[] args) {
SpringApplication.run(PersistenceClasses .class, args);
}
}
Thank you for any insights you can provide.
