Question

我有一个Spring数据存储库，其中包含以下方法：

public interface ImportAssetWrapperRepository extends PagingAndSortingRepository<ImportAssetWrapper, Long> {

   ImportAssetWrapper findByAssetId(String assetId);

   List<ImportAssetWrapper> findByAssetId(String assetId, PageRequest pageRequest);

在调用这些方法的控制器中，findAssetById（String assetId）工作正常，表明查询结构正确。

尝试findAll（可分页可分页）也可以正常工作，因此存储库的Pageable方面也可以正常工作（至少对于这种默认方法）。

但是，当我尝试使用List findByAssetId（String assetId，PageRequest pageRequest）时使用：

for(ImportAssetWrapper ia : repository.findByAssetId("asset-version-123456",pr)){
        log.info("Processing new import asset: " + ia.getFilePath());
    }

我得到以下异常：

我无法弄清楚为什么会发生这种情况，因为这几乎与documentation

的例1.5中给出的例子相同

Answer 1

似乎我复制了一个不起作用的例子。

将PageRequest更改为Pageable可解决此问题：

List<ImportAssetWrapper> findByAssetId(String assetId, Pageable pageable);

Answer 2

根据 spring-data-commons 文档 http://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/repository/PagingAndSortingRepository.html

PagingAndSortingRepository 适用于 Pageable / Sort

Spring Data Repository java.util.NoSuchElementException
