How to get all results in one page using Spring Data Pagination
提问by Ruwanka Madhushan
I want to get all the results in single page, I've tried with
我想在单页中获得所有结果，我已经尝试过
Pageable p = new PageRequest(1, Integer.MAX_VALUE);
return customerRepository.findAll(p);
Above is not working, is there any methods to achieve this? Seems like it cannot be achieved from custom query as asked here.
以上不起作用，有什么方法可以实现吗？似乎无法从此处询问的自定义查询中实现。

Your page request is incorrect because you are looking for results at the wrong page. It should be:
您的页面请求不正确，因为您在错误的页面上查找结果。它应该是：
new PageRequest(0, Integer.MAX_VALUE);
First page for results is 0. Since you're returning all records, they are all on this page.
结果的第一页为 0。由于您要返回所有记录，因此它们都在此页上。

If you pass null for Pageable, Spring will ignore it and brings all data.
如果为 Pageable 传递 null，Spring 将忽略它并带来所有数据。
Pageable p = null;
return customerRepository.findAll(p);

The more correct way is to use Pageable.unpaged()
更正确的方法是使用Pageable.unpaged()
Pageable wholePage = Pageable.unpaged();
return customerRepository.findAll(wholePage);
