I have about 30 tables that I need to fill from an XML file. And I want to use JPA for that purpose.
Now I have 30 classes annotated with @Entity, config that scans entities and repositories;
Also I have:
@Repository
public interface MyRepository extends JpaRepository<MyEntity1, Long> {
}
And (some controller):
@Autowired
public MyRepository myRepository;
...
...
MyEntity1 entity = new MyEntity(...);
myRepository.save(entity);
It works fine with one @Entity but should I define 30 repositories for that?
I thought I could do something like this:
@Repository
public interface MyRepository<T> extends JpaRepository<T, Long> {
}
and then:
@Autowired
public MyRepository<MyEntity1> myRepository1;
@Autowired
public MyRepository<MyEntity2> myRepository2;
but that gave an error:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myRepository1': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class java.lang.Object
