spring-data-rest에서 엔티티 응답을 사용하는 방법

2016-10-13 2 views

REST API를 노출하기 위해 spring-data-rest를 사용하고 있습니다. 내 검색 방법 중 하나가 엔티티 목록을 반환합니다. 저장소 및 나머지 응답spring-data-rest에서 엔티티 응답을 사용하는 방법

List<Order> findByKeywordContaining(String keyword);

검색 응답을 다음과 같이 이제

{ 
    "_embedded":{ 
     "orders":[ 
     { 
      "keyword":"Iron mattress", 
      "name":"Hostel", 
      "_links":{ 
       "self":{ 
        "href":"http://localhost:8081/orders/2" 
       }, 
       "order":{ 
        "href":"http://localhost:8081/orders/2" 
       } 
      } 
     }, 
     { 
      "keyword":"Iron", 
      "name":"Weat strong", 
      "_links":{ 
       "self":{ 
        "href":"http://localhost:8081/orders/40" 
       }, 
       "order":{ 
        "href":"http://localhost:8081/orders/40" 
       } 
      } 
     } 
     ] 
    }, 
    "_links":{ 
     "self":{ 
     "href":"http://localhost:8081/orders/search/findByKeywordContaining?keyword=iron" 
     } 
    } 
}

나는 다음과 같이 클라이언트 측에서 처리하기 위해이 응답을 소비하는 RestTemplate을 사용하고

List<Order> orders = restOperations.exchange(new URI(url), HttpMethod.GET, null, new ParameterizedTypeReference<Resource<List<Order>>>() {}).getBody().getContent();

위의 코드는 응답의 단일 객체에 대해 잘 작동하지만 응답에 여러 객체가 포함되어있는 경우에 적합합니다. 코드에서 다음 오류가 발생합니다.

org.springframework.http.converter.HttpMessageNotReadableException: Could not read JSON: Unrecognized field "_embedded" (class org.springframework.hateoas.Resource), not marked as ignorable (3 known properties: , "links", "content", "page"]) 
at [Source: [email protected]c870; line: 2, column: 18] (through reference chain: org.springframework.hateoas.Resource["_embedded"]); nested exception is com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "_embedded" (class org.springframework.hateoas.Resource), not marked as ignorable (3 known properties: , "links", "content", "page"])

내가 여기에 누락 되었습니까? 위의 응답을 List로 소비하는 방법은 무엇입니까?

Order.java

public class Order { 
private int id; 
private String name; 
private String keyword; 
private Agent agent; 

public int getId() { 
    return id; 
} 

public void setId(int id) { 
    this.id = id; 
} 

public String getName() { 
    return name; 
} 

public void setName(String name) { 
    this.name = name; 
} 

public String getKeyword() { 
    return keyword; 
} 

public void setKeyword(String keyword) { 
    this.keyword = keyword; 
} 

public Agent getAgent() { 
    return agent; 
} 

public void setAgent(Agent agent) { 
    this.agent = agent; 
}

당신이 돈 경우 귀하의 주문 클래스는, 응답에 따라 매핑 모든 필드를 가지고하지 않는 문제가있다 ' 모든 필드를 원한다면 Order 클래스에서 Jackson의 주석을 사용하여 무시하십시오. -

    public Agent getAgent() { 
     return agent; 
    } 

    public void setAgent(Agent agent) { 
     this.agent = agent; 
    } 

}

하고 주석을 확인 그래서 당신이 (당신이 요 당신의 JSON 응답에 따라 조정할 수 있습니다) 아래와 같은 클래스 대응 방법 작성 나는 스프링 hateoas Traverson 대신 RestTe를 사용하여 문제를 해결

Response reeponse = restOperations 
       .exchange(new URI(url), HttpMethod.GET, null, new ParameterizedTypeReference<Response>() { 
       }).getBody().getContent();

정확히 동일한 restTemplate.exchange() 호출을 만들 수 있지만 단일 엔터티에 대한 org.springframework.hateoas.Resource 래퍼 클래스가 아닌 엔터티 컬렉션에 org.springframework.hateoas.Resources 래퍼 클래스를 사용해야합니다. 나는. new ParameterizedTypeReference<Resources<Order>>() {}을 네 번째 매개 변수로 사용하십시오.

이 호출에 의해 반환되지만 오류가 기록되지 않은 래핑 된 빈 콜렉션을 얻은 경우에는 org.springframework.data:spring-data-rest-core 종속성이 있는지 확인하십시오. 오늘 디버깅에 많은 시간을 쏟았다.
