彈簧規格和可分頁

我該如何使用它一起（規範和可分頁）？彈簧規格和可分頁

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);

當我運行它時，出現這樣的錯誤。但我調用findAll（Pageable頁面）和findAll（規範過濾器）它分開findAll（）函數。但我不能一起使用它。

你怎麼使用這個，你能提供一些代碼嗎？我當然是 –

。 –

您需要添加countQuery支持分頁

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

，我想你需要引用spec不知何故在查詢

它不起作用。 –

不起作用意味着什麼。張貼完全你做了什麼，確切的結果 - 錯誤等 – StanislavL

我得到同樣的錯誤 –

通過編輯personelService.java解決和刪除findData功能personelRepository。我使用springframework.data.jpa.repository.JpaRepository findAll（）函數，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; 
}
