I tried to use spring boot with JPA and I got the following error :
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'accountCommand': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.compta.repositories.AccountRepository com.compta.commands.AccountCommand.accountRepository; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.compta.repositories.AccountRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

My code :

public void setName(String name) {

}
}
@Repository

}
@Service
public class AccountCommand {
@Autowired
private AccountRepository accountRepository;
public Account create() {
return accountRepository.save(new Account());
}
}
Any idea?
Looking at your stack trace it seems that your Compta
class is not in any package. This can cause problems (see http://docs.spring.io/spring-boot/docs/current/reference//htmlsingle/#using-boot-using-the-default-package) so I'd try putting all of your classes in a package first.
Also check that your AccountRepository
is in the same package, or a sub-package of Compta
.
If you're still having problems, perhaps you can share a complete project that replicates the problem?
