如何在没有Spring数据的情况下使用Spring Page

Question

Hi i'm using below code for find article using spring with plain hibernate.

public List<Article>  getArticles(int currPosition, int pageSize) {
        Criteria c = getSession().createCriteria(Article.class);
        c.addOrder(Order.desc("createdDate"));
        c.setFirstResult(currPosition);
        c.setMaxResults(pageSize);
        List<Article> result = c.list();
        return result;
    }

i'm not using spring data in my project now, So how can i use org.springframework.data.domain.Page with my project.

Page<Person> persons = personService.findAllPageable(new PageRequest(evalPage, evalPageSize));

Answer 1

您可以使用Pageable＃getSize来设置maxResults ， setFirstResult Pageable＃getOffset以及Pageable＃getSort来获得排序参数。

Answer 2

You can even use pagerequest :

public class PagePersons implements Serializable {
     private List<Persons> persons ;
     private int page ;
     private int numberPersons ;
     private int totalPersons ;
     private int totalPage ;

 //getters setters
}

and call your persons repository for exemple

   public PagePersons getPagePersons(int codePerson, int page, int size) {
    Page<Person> Persons= personRepository.getPagePersons(codePerson, new PageRequest(page, size));

   PagePersons pagePersons =new PagePersons();
   pagePersons.setPersons(persons.getContent());
   pagePersons.setPage(page);
   pagePersons.setNumbrePersonss(persons.getNumberOfElements());
   pagePersons.setTotalPage(persons.getTotalPages());
   pagePersons.setPage(page);

    return  pagePersons ;
    }
