spring-data-mongodb

问题 I have been evaluating to adopt spring-data-mongodb for a project. In summary, my aim is: Using existing XML schema files to generate Java classes.

问题 I was developing a little application with spring data mongo and angularjs . Here is model : public class Lease { @Id private String id; private long created; private Lessor lessor; private Lessee lessee; } public class Payment { @Id private String id; private Integer month; private Integer year; private Long amount; private String leaseId; } I did not embed Payment model as I need it to have an id and edit it in its own form.

问题 I already went through many links but did not find solution. Here is my code: @Value("${paging.default.pageSize}") public int pageSize; Controller method: @GetMapping() public ResponseEntity<Page<Employee>> getAllEmployee(@PageableDefault(size = pageSize) Pageable pageable) { return countryService.findAllCountries(pageParams, pageable); } The value for annotation attribute PageableDefault.size must be a constant expression 来源： https://stackoverflow.com/questions/56107812/the-value-for
