Question

如何實現一個方法，使用JpaRepository而不是PagingAndSortingRepository返回一頁對象？

我的倉庫

public interface GroupRepository extends JpaRepository<Group, Long> { 
    @Query(value = "SELECT g FROM Group") 
    Page<Group> listAllByPage(Pageable pageable); 
} 

我的服務實現：

@Override 
public 
Page<Group> findGroupesByPagination(Pageable pageable) { 
    return groupeRepository.listAllByPage(pageable); 
} 

我休息控制器的方法：

@RequestMapping(value="/groups", method = RequestMethod.GET) 
public @ResponseBody Page<Group> list(Pageable pageable){ 
    Page<Group> groupes = groupeServiceImpl.findGroupesByPagination(pageable); 
    return groupes; 
} 

最後我得到這個錯誤：

Error creating bean with name 'groupServiceImpl': Unsatisfied dependency expressed through field 'groupeRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'groupRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Validation failed for query for method public abstract org.springframework.data.domain.Page rimtrack.org.repository.GroupRepository.listAllByPage(org.springframework.data.domain.Pageable)!

Answer 1

The query can be defined by an annotation somewhere or declared by other means. Consult the documentation of the specific store to find available options for that store. If the repository infrastructure does not find a declared query for the method at bootstrap time, it fails.

你應該使用Spring Data Jpa方法。 Reference

Page<T> findAll(Pageable pageable); 

請更改存儲庫類。

考試：

public interface GroupRepository extends JpaRepository<Group, Long> { 
    Page<Group> findAlll(Pageable pageable); 
}
