springdata之PagingAndSortingRepository实现分页功能

PersonRepsotory接口

public interface PersonRepsotory extends PagingAndSortingRepository<Person, Integer> {}

具体实现

@Test

public void PagingAndSortingRepository() {

// pageNo从0开始

int pageNo = 6 - 1;

int pageSize = 5;

// PageRequest接口通常使用的起PageRequest实现类，其中封装了需要分页的信息

PageRequest pageRequest = new PageRequest(pageNo, pageSize);

Page<Person> page = personRepsotory.findAll(pageRequest);

System.out.println("总记录数：" + page.getTotalElements());

System.out.println("当前第几页：" + page.getNumber());

System.out.println("总页数" + page.getTotalPages());

System.out.println("当前页面的list：" + page.getContent());

System.out.println("当前页面记录数：" + page.getNumberOfElements());

}
