Json 웹 응답에서 Json 노드를 가져 오는 중 오류가 발생했습니다.

Question

호텔 API에서 json 웹 응답을받는 간단한 Spring Web MVC 응용 프로그램을 만들었지 만 루트 노드에서 findPath() 메서드를 사용하려고 할 때 I 오류가 발생합니다. json 파싱을 위해 Jackson Library를 사용하고 있습니다.

ObjectMapper m = new ObjectMapper(); 
JsonNode rootNode = m.readTree(in); 
JsonNode hotelNameNode = rootNode.findPath("HotelList"); 
String hotelName = hotelNameNode.path("name").getTextValue(); 

제 3 라인이 오류가 발생합니다 : 다음은 코드입니다.

Answer 1

당신은 jackson-mapper-asl를 업데이트 할 필요가있을 수 있습니다, 그것은 최대의 여기
