弹簧规格和可分页

我该如何使用它一起（规范和可分页）？弹簧规格和可分页

personelRepository.java

@Query("SELECT e FROM PersonelEntity e ") 
List<PersonelEntity> findData(Specification<PersonelEntity> test, Pageable pageable);

personelService.java

public List<PersonelEntity> filteredData(Specification<PersonelEntity> filter,Pageable pageable){ 
    List<PersonelEntity> filteredData = personelRepository.findData(filter,pageable); 
    return filteredData; 
}

personelController.java

Pageable reqCount = new PageRequest(0, 10); 
Specification<PersonelEntity> filter = new FilterSpecification<PersonelEntity>(new SearchCriteria("name", "=","lux")); 
personels = personelService.findData(filter,reqCount);

当我运行它时，出现这样的错误。但我调用findAll（Pageable页面）和findAll（规范过滤器）它分开findAll（）函数。但我不能一起使用它。

你怎么使用这个，你能提供一些代码吗？我当然是 –

。 –

您需要添加countQuery支持分页

@Query(query ="SELECT e FROM PersonelEntity e " 
     ,countQuery ="select count(e.id) from PersonelEntity e"

，我想你需要引用spec不知何故在查询

它不起作用。 –

不起作用意味着什么。张贴完全你做了什么，确切的结果 - 错误等 – StanislavL

我得到同样的错误 –

通过编辑personelService.java解决和删除findData功能personelRepository。我使用springframework.data.jpa.repository.JpaRepository findAll（）函数，它的工作原理。

public List<PersonelEntity> filteredData (Specification<PersonelEntity> spec, Pageable pageable){ 
    Page<PersonelEntity> pageData = personelRepository.findAll(spec,pageable); 
    List<PersonelEntity> filteredData = pageData.getContent(); 
    return filteredData; 
}
