问题 Under Boot 1.3.0.M5 i use in application.properties spring.data.rest.max-page-size=10 But i still can set the size to 40 in a URL and get a correct response. For example : http://localhost:8080/cine20-spring/api/films?page=0&size=40&sort=title,asc will give me back 40 films So what is the use of this parameter ?

问题 I've got a server that exposes resources through spring-data-rest and this uses, as far as I understand HAL or HATEOAS. But when I try to use it in combination with Feign, I can't seem to be able to register a Jackson2HalModule that gets picked up.
