带有可分页参数的呼叫服务-最佳实践问题

Question

I have a service MyMainService that makes a call to another service MySecondaryService within the same package. The method getPagesOfMyObjects being called in MySecondaryService returns a Page of objects of type MyObject and one of the method's parameters is a Pageable object. MyMainService is, at present, not concerned with pagination. But because I need to call the getPagesOfMyObjects method in MySecondaryService I need to provide it with a Pageable object that won't exclude any records that I might need. My current solution (not very good) is to pass this as the Pageable parameter

public class MyMainServiceImpl implements MyMainService {

    @Autowired
    private MySecondaryService mySecondaryService

    public void myMethod() {
        Page<MyObject> pages = mySecondaryService.getPagesOfMyObjects(PageRequest.of(0, 10000));
        List<MyObject> myObjects = pages.getContent();
        //do stuff
    }

}

As you can see it has 10000 hard-coded as its size parameter. This doesn't feel like good practice to me. Is there a better way to call this service? I don't have the option of re-writing the existing getPagesOfMyObjects method.

Answer 1

最后，我使用Pageable.unpaged()作为参数来代替PageRequest.of(0, 10000) ，它似乎有效。
