如何创建未分页但已排序的 Pageable.of(unpaged, unpaged, Sort ) 到 spring 数据 jpa 存储库？

Question

How do I pass a Pageable object to Spring JPA Repository with only Sorting information? I want something like this:

Pageable pageable = PageRequest.of(null, null, Sort());

I know it takes int as page and size but if we can somehow not use those values and give an unpaged result with only

Sort.by(Sort.Direction.ASC, "age")

We could use a high number like 1000 , 1000 for page and size but I do not want to hardcode these values.

I am also not looking to create a custom impl for Pageable .

Please let me know how to achieve this.

Thanks in advance.

Answer 1

According to the documentation for the current version of Spring Data JPA , you can pass a Sort directly to a query method, so you could have two versions of the same query method:

• One receiving a Pageable , for use when you have a "full" Pageable .
• Another one receiving a Sort , for use when you just want to perform sorting.

Answer 2

You could pass Pageable.unpaged() in the query and then sort the result ( list.getContent().sort(Comparator.comparing(Item::getName)) ) if you are adamant about using the existing query.
