Java Spring Boot REST：忽略排序方向，但排序通常有效

我正在用Spring Boot编写一个RESTAPI。因此，我通过名字来获取员工。我正在传递

Pageable

参数进行排序，问题是忽略了方向。因此Spring总是对ascnerve

desc

进行排序，这是默认行为。我不知道我做错了什么

我需要补充的是，排序通常是有效的，因为如果我不将

chrValue

作为

sort

参数传递，我会得到像存储在数据库中一样的项目

请求：

http://localhost:8080/dimensionAttributeValues/search/findDimensionAttributeValueByDimensionAttributeDimensionAttributeID?dimensionAttributeId=1&page=0&size=1&sort=chrValue&chrValue.dir=desc

存储库：

@RepositoryRestResource(collectionResourceRel = "dimensionAttributeValue", path = "dimensionAttributeValues")
@CrossOrigin(exposedHeaders="Access-Control-Allow-Origin")
public interface DimensionAttributeValueRepository extends PagingAndSortingRepository<DimensionAttributeValue, Long> {
    Page<DimensionAttributeValue> findDimensionAttributeValueByDimensionAttributeDimensionAttributeID(@Param(value = "dimensionAttributeId") long dimensionAttributeId, Pageable pageable);
    Page<DimensionAttributeValue> findDimensionAttributeValueByMasterDataMasterDataIDAndDimensionAttributeDimensionAttributeID(@Param(value = "masterDataId") long masterDataId, @Param(value = "dimensionAttributeId") long dimensionAttributeId, Pageable pageable);
    Page<DimensionAttributeValue> findDimensionAttributeValueByDimensionAttributeDimensionDimensionIDOrDimensionAttributeDimensionAttributeIDOrderByChrValue(@Param(value="dimensionID") long dimensionID, @Param(value = "dimensionAttributeID") long dimensionAttributeID, Pageable pageable);
    Page<DimensionAttributeValue> findAllByDimensionAttributeDimensionAttributeIDAndChrValueStartingWith(@Param(value = "dimensionAttributeId") long dimensionID, @Param(value = "chrValue") String chrValue, Pageable pageable);

}

有什么想法吗？谢谢

试试这个URL

http://localhost:8080/dimensionAttributeValues/search/findDimensionAttributeValueByDimensionAttributeDimensionAttributeID?dimensionAttributeId=1&page=0&size=1&sort=chrValue，desc

这将按降序对数据进行排序。

url参数是否区分大小写？因为您的列名是“ChrValue”，大写C，参数是ChrValue。好主意，我试过了，但行为相同。另外，我认为spring总是使用属性名。在您的请求中，您传递size=1是否正确？是的，但对于size=20或size=200，我有相同的行为。@Max尝试一下<代码>http://localhost:8080/dimensionAttributeValues/search/findDimensionAttributeValueByDimensionAttributeDimensionAttributeID?dimensionAttributeId=1&page=0&size=1&sort=chrValue，desc
