Data JPA [PageRequest] object JSON String can't revert!

[willofad]

		PageRequest page = new PageRequest(0, PAGE_SIZE, new Sort(
				Sort.Direction.DESC, "date"));
		Page<User> users = this.dao.findAll(page);

		ObjectMapper mapper = new ObjectMapper();
		
		ByteArrayOutputStream out = new ByteArrayOutputStream();
		mapper.writeValue(out, page);
		
		String json = new String(out.toByteArray());
		
		page = mapper.readValue(json, PageRequest.class);

Exception message:
org.codehaus.jackson.map.JsonMappingException: No suitable constructor found for type [simple type, class org.springframework.data.domain.PageRequest]: can not instantiate from JSON object (need to add/enable type information?)......

It (by default) requires a default no-args constructor which isn't available for the PageRequest class. You should be able to override this by creating your json serializer.
