Wie Liste der Entitäten Antwort von Frühjahr-Daten-Rest zu konsumieren

Ich verwende Spring-Daten-Rest, um REST API zu offenbaren. Eine meiner Suchmethoden gibt eine Liste von Entitäten zurück. Das Repository und Rest Antwort alsWie Liste der Entitäten Antwort von Frühjahr-Daten-Rest zu konsumieren

folgt 
List<Order> findByKeywordContaining(String keyword);

Suchaktion:

{ 
    "_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" 
     } 
    } 
}

Jetzt habe ich RestTemplate bin mit dieser Antwort zu konsumieren in Client-Seite wie folgt zu verarbeiten

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

Die Der obige Code eignet sich für ein einzelnes Objekt als Antwort, aber wenn die Antwort mehrere Objekte enthält. Der Code löst den folgenden Fehler aus

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"])

Was fehlt mir hier? Wie kann die obige Antwort als Liste verwendet werden?

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; 
}

Problem ist Ihre Order-Klasse ist nicht alle Felder nach der Antwort zugeordnet ist, also, wenn Sie don‘ t wollen Sie alle Felder, ignorieren Sie sie, indem Sie Jacksons Annotation in Ihrer Order-Klasse verwenden -

@JsonIgnoreProperties(ignoreUnknown = true) 
    public class Order { 
    ... 
    }

EDIT: OK, so erstellen Sie Klasse Reaktion wie unten (Sie es nach yo Ihrer Json Antwort einstellen) -

class Response{ 
    @JsonProperty("_embedded") 
    private Embedded embedded; 

    public Embedded getEmbedded() { 
     return embedded; 
    } 

    public void setEmbedded(Embedded embedded) { 
     this.embedded = embedded; 
    } 
} 


class Embedded{ 
    @JsonProperty("orders") 
    List<Order> orders = new ArrayList<Order>(); 

    public Embedded(){ 

    } 

    public List<Order> getOrders() { 
     return orders; 
    } 

    public void setOrders(List<Order> orders) { 
     this.orders = orders; 
    } 
} 


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

    @Override 
    public String toString() { 
     return "Order [id=" + id + ", name=" + name + ", keyword=" + keyword + "]"; 
    } 

    public Order(){ 

    } 

    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; 
    } 

}

Sie sollten denselben restTemplate.exchange()-Aufruf durchführen können, aber die Wrapper-Klasse org.springframework.hateoas.Resources für eine Auflistung von Entities und nicht die Wrapper-Klasse org.springframework.hateoas.Resource für eine einzelne Entität verwenden. I.e. new ParameterizedTypeReference<Resources<Order>>() {} als der 4. Parameter.

Beachten Sie, dass, wenn Sie eine eingewickelte leere Sammlung durch diesen Aufruf zurückgegeben, aber keine Fehler protokolliert, dann stellen Sie sicher, dass Sie die org.springframework.data:spring-data-rest-core Abhängigkeit haben - ich selbst und ein anderer Entwickler haben verbrachte viel von heute Debugging dies!
