JpaRepository：Paging query needs to have a Pageable parameter! Offending method public abstract

在练习 Spring Data JPA 时，使用分页接口 Pageable 查询数据，接口实现后，运行报错：
Paging query needs to have a Pageable parameter! Offending method public abstract
实现代码摘要：

import org.springframework.data.domain.Page;
import java.awt.print.Pageable
...
@Service
public class AyUserServiceImpl implements AyUserService {
    @Resource
        private AyUserRepository ayUserRepository;
    ...
    @Override
        public Page<AyUser> findAll(Pageable pageable){
            return ayUserRepository.findAll(pageable);
        }
}

后来发现，Pageable 的包名不对，改成了
import org.springframework.data.domain.Pageable;
运行就正常了
