PagingAndSortingRepository接口

PagingAndSortingRepository

Iterable<T> findAll(Sort sort); //排序
Page<T> findAll(Pageable pageable); //分页查询（含排序功能）

public class SpringDataTest {
private ApplicationContext ctx = null ;
PersonRepsotory personRepsotory = null;

{
ctx =  new ClassPathXmlApplicationContext("applicationContext.xml");
personRepsotory = ctx.getBean(PersonRepsotory.class);

}

public void testPageingAndSortingRepsotory(){
// pageNo 是从0 开始
int pageNo = 3-1; //第几页 此为第三页
int pageSize = 5;
// Pageable 接口通常使用其PageRequest 实体类,其中封装了需要分页的信息
// 排序相关的 Sort 封装了培训的信息

//Order 是具体针对某一个属性进行升序还是降序
Order order1 = new Order(Direction.DESC,"id");
Order order2 = new Order(Direction.ASC,"email");
Sort sort = new Sort(order1,order2);
PageRequest pageable = new PageRequest(pageNo,pageSize,sort);
// PageRequest pageable = new PageRequest(pageNo,pageSize);

Page<Person> page = personRepsotory.findAll(pageable);
System.out.println("总记录数：" + page.getTotalElements());
System.out.println("当前第几页" + (page.getNumber()+1));
System.out.println("总页数" + page.getTotalPages());
System.out.println("当前页码的list" +page.getContent() );
System.out.println("当前页面的记录数" + page.getNumberOfElements());
