Question

我有一个API POST端点，它返回一个结构如下的json对象：

数据（我发送的原始数据）
JsonAPI（端点符合的JSON API版本）
状态（对端点的调用状态）
消息（在架构验证错误的情况下使用）

所有这些都使用GSON fromJson（）：

存储在以下POJO中

package json.responses;
import com.google.gson.JsonElement;

public class SupplierResponseTest {

    private StatusResponse status;
    private JsonElement jsonapi;
    private String message;
    private JsonElement data;


    public SupplierResponseTest(StatusResponse status, JsonElement jsonapi) {
        this.status = status;
        this.jsonapi = jsonapi;

    }
    public SupplierResponseTest(StatusResponse status, JsonElement jsonapi, String message) {
        this.status = status;
        this.jsonapi = jsonapi;
        this.message = message;
    }
    public SupplierResponseTest(StatusResponse status, JsonElement jsonapi, JsonElement data) {
        this.status = status;
        this.jsonapi = jsonapi;
        this.data = data;

    }
    public StatusResponse getStatus() {
        return status;
    }
    public JsonElement getJsonapi() {
        return jsonapi;
    }
    public String getMessage() {
        return message;
    }
    public JsonElement getData() {
        return data;
    }

}

如您所见，我目前将jsonapi值存储为JsonElement。这意味着当我从json解析值时，我最终得到的字符串值为{"version":"1.0"}。

我的目标是将此值存储为子（？）对象。并且，不是api值是SupplierResponseTest中的JsonElement，而是将其作为对象或枚举。但是，我对如何做到这一点感到困惑。

以这种方式存储值的目的是能够对新对象的值1.0执行黄瓜验证，而不是解析一堆json {"version":"1.0"}。

我正在使用的黄瓜是：

Scenario Outline: Add Supplier Details
    Given the system does not know about any Suppliers
    When the client adds the following <supplier>
    Then the response status is <status>
    And the response has the <jsonapi> version
    And the response has the request <supplier>

        Examples:
        | supplier                  | status    | jsonapi   |
        | "Blue Network Energy LTD" | "SUCCESS" | "1.0"     |

我遇到的具体步骤定义是：

@Then("^the response has the \"([^\"]*)\" version$")
public void the_response_has_the_version(String arg1) throws Throwable {

    try{            

        //This returns a string of json...
        JsonElement apiVersion = supplierResponse.getJsonapi();

        //The below attempts to assert the two values "1.0" and {"version":"1.0"} 
        Assert.assertEquals(arg1, apiVersion.toString());

    } catch (Exception e){
        System.out.println(e.getMessage());
    }


}

好的，我从this question起了带头。

我创建了一个新类，它涵盖了嵌套的json元素：

package json.responses;
public class ApiVersionResponseTest { 

    private String version;

    private ApiVersionResponseTest(String version) { 
        this.version = version;
    }


    public String getApiVersion() {
        return version;
    }

}

更改了父类构造函数以允许将apiversion传递并创建为新对象：

package json.responses;
import com.google.gson.JsonElement;

public class SupplierResponseTest {

    private StatusResponseTest status;
    private ApiVersionResponseTest jsonapi; //Relevant change
    private String message;
    private JsonElement data;


    public SupplierResponseTest(StatusResponseTest status, ApiVersionResponseTest jsonapi) {
        this.status = status;
        this.jsonapi = jsonapi;

    }
    public SupplierResponseTest(StatusResponseTest status, ApiVersionResponseTest jsonapi, String message) {
        this.status = status;
        this.jsonapi = jsonapi;
        this.message = message;
    }
    public SupplierResponseTest(StatusResponseTest status, ApiVersionResponseTest jsonapi, JsonElement data) {
        this.status = status;
        this.jsonapi = jsonapi;
        this.data = data;

    }
    public StatusResponseTest getStatus() {
        return status;
    }
    public ApiVersionResponseTest getJsonapi() {
        return jsonapi;
    }
    public String getMessage() {
        return message;
    }
    public JsonElement getData() {
        return data;
    }   
}

步骤定义（现在正在工作）调用嵌套对象，如下所示：

@Then("^the response has the \"([^\"]*)\" version$")
public void the_response_has_the_version(String arg1) throws Throwable {

    try{            

        Assert.assertEquals(arg1, supplierResponse.getJsonapi().getApiVersion());

    } catch (Exception e){
        System.out.println(e.getMessage());
    }


}

Bingo bango。固定。
