放置在具有嵌套值的JSON响应一个Java POJO

Question

我有一个API POST端点返回结构类似于这样一个JSON对象：

• 数据（I发送了原始数据）
• JsonAPI（该JSON的API版本端点符合）
• 状态（通话状态到端点）
• 消息（用于在架构验证错误的情况下）

的这些都是使用GSON fromJson（）存储在以下POJO：

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; 
    } 

} 

正如你可以看到我目前存储jsonapi值作为JsonElement。这意味着当我解析json的值时，最终的字符串值为{"version":"1.0"}。

我的目标是将此值存储为子（？）对象。而且，而不是在SupplierResponseTest中的api值为JsonElement，因为它是一个对象或枚举。但是，我坚持要如何做到这一点。

以这种方式存储值的目的是为了能够对新对象的值进行黄瓜验证，该值将为1.0，而不是解析一堆json {"version":"1.0"}。

我使用的黄瓜：

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"  | 

我在遇到问题的具体步骤定义是：

@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()); 
    } 


}

好吧，我率先从this question。

我创建了一个新的类，其覆盖嵌套JSON元件：

package json.responses; 
public class ApiVersionResponseTest { 

    private String version; 

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


    public String getApiVersion() { 
     return version; 
    } 

} 

父类构造函数被改变，以允许apiversion传递和创建为新的对象：

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（现在工作）像这样调用嵌套对象：

@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()); 
    } 


}
