java - 如何防止Spring创建一个刚刚扩展的 "abstract"泛型类型存储库？

Question

如果我想做这样的事情:

public interface LongIdRepo<T> extends PagingAndSortingRepository<T, Long> {}

因为我想将其扩展为:

public interface MyRepo extends LongIdRepo<My> {}

这是不可能的，因为:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'longIdRepo': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class java.lang.Object

有没有办法让Spring忽略LongIdRepo bean的创建？

Answer 1

试试这个 @NoRepositoryBean注释

@NoRepositoryBean
public interface LongIdRepo<T> extends PagingAndSortingRepository<T, Long> {}
