问题 Problem I have two entities defined: School and District . A district can have many schools and a school can belong to one district. When executing a GET request against this endpoint http://localhost:8080/districts I would like to get a list of all the districts WITHOUT fetching each district's set of associated schools. But it seems like no matter what I do, hibernate is making DB calls to fetch data for each school individually. Entities School @Getter @Setter @NoArgsConstructor @Entity

问题 I have the following controller method: @RequestMapping(produces = MediaType.APPLICATION_JSON_VALUE, value = "session/{id}/exercises") public ResponseEntity<Resources<Exercise>> exercises(@PathVariable("id") Long id) { Optional<Session> opt = sessionRepository.findWithExercises(id); Set<Exercise> exercises = Sets.newLinkedHashSet(); if (opt.isPresent()) { exercises.addAll(opt.get().getExercises()); } Link link = entityLinks.linkFor(Session.class) .slash(id) .slash(Constants.Rels.EXERCISES)

问题 Usually CollectionModel will return an _embedded array, but in this example: @GetMapping("/{id}/productMaterials") public ResponseEntity<?> getProductMaterials(@PathVariable Integer id) { Optional<Material> optionalMaterial = materialRepository.findById(id); if (optionalMaterial.isPresent()) { List<ProductMaterial> productMaterials = optionalMaterial.get().getProductMaterials(); CollectionModel<ProductMaterialModel> productMaterialModels = new ProductMaterialModelAssembler

问题 In my current Spring HATEOAS 0.25.1.RELEASE project I make heavy use of ResourceProcessor interfaces: @Bean public ResourceProcessor<Resource<Person>> personProcessor() { return new ResourceProcessor<Resource<Person>>() { @Override public Resource<Person> process(Resource<Person> resource) { resource.add(new Link("http://localhost:8080/people", "added-link")); return resource; } }; } How can can I migrate my ResourceProcessors to Spring HATEOAS 1.0.0 M1? 回答1: In Spring HATEOAS 1.0 M1, a lot
