Question

我尝试在Spring Boot for RESTFul中使用PagingAndSortingRepository。

 @Repository
public interface PrsMainRepo extends PagingAndSortingRepository<PrsMain, String> {
    @Query(value = "SELECT * FROM PagingFilter(?1,?2) ORDER BY ?#{#pageable}", nativeQuery = true)
    Page<PrsMain> findAll(String colName, String condition, Pageable pageable);
}

这是我的主存储库，当我使用postman运行项目和测试时，我得到了hibernate日志记录：

2017-12-25 15:20:32.370 DEBUG 7532 --- [nio-8080-exec-1] org.hibernate.SQL                        : SELECT * FROM PagingFilter(?,?) ORDER BY ? limit ? offset ?

这是返回数据的空内容。我不知道为什么，如何解决这个问题？（只有SELECT * FROM PagingFilter（？1，？2）正在运行）

{
"content": [],
"pageable": {
    "sort": {
        "sorted": false,
        "unsorted": true
    },
    "offset": 60,
    "pageSize": 10,
    "pageNumber": 6,
    "paged": true,
    "unpaged": false
},
"last": true,
"totalElements": 12,
"totalPages": 2,
"size": 10,
"number": 6,
"sort": {
    "sorted": false,
    "unsorted": true
},
"numberOfElements": 0,
"first": false

}

Answer 1

它闻起来像给出页面索引的常见错误。请参阅有关 PageRequest 的文档。

页面为零索引，因此为页面提供0将返回第一页。

Page <t>空内容
