java - 无法从 Pojo 类反序列化 JSON 响应和访问类
问题描述
我正在创建 pojo 类来反序列化 Rest Assured 中的 JSON 响应。我还在反序列化过程中利用了 Lombok 注释。
这是一个 JSON 响应，是我测试的重点。它有多个嵌套列表，就像我将要测试的许多其他响应一样。
{
"annualReturnFilingMonth": null,
"financialReportFilingMonth": null,
"nzsxCode": null,
"annualReturnLastFiled": "2002-05-29T12:15:56.000+1200",
"hasConstitutionFiled": true,
"countryOfOrigin": "NZ",
"overseasCompany": "No",
"extensiveShareholding": false,
"stockExchangeListed": null,
"shareholding": {
"numberOfShares": 300,
"shareAllocation": [
{

]
}
],
"historicShareholder": []
},
"ultimateHoldingCompany": null,
"australianCompanyNumber": null,
"insolvencies": [],
"removalCommenced": false
}
下面是我为上述响应创建的 POJO 类
import lombok.Data;
import java.util.Date;
import java.util.List;
public class Shareholders {
Root root;
Shareholding shareholding;
ShareAllocation shareAllocation;
Shareholder shareholder;
ShareholderAddress shareholderAddress;
IndividualShareholder individualShareholder;
}
@Data
class Root {
public Object annualReturnFilingMonth;
public Object financialReportFilingMonth;
public Object nzsxCode;
public Date annualReturnLastFiled;
public boolean hasConstitutionFiled;
public String countryOfOrigin;
public String overseasCompany;
public boolean extensiveShareholding;
public Object stockExchangeListed;
public Shareholding shareholding;
public Object ultimateHoldingCompany;
public Object australianCompanyNumber;
public List<Object> insolvencies;
public boolean removalCommenced;
}
@Data
class Shareholding{
public int numberOfShares;
public List<ShareAllocation> shareAllocation;
public List<Object> historicShareholder;
}
@Data
class ShareAllocation{
public int allocation;
public List<Shareholder> shareholder;
}
@Data
class Shareholder{
public String type;
public Date appointmentDate;
public Object vacationDate;
public IndividualShareholder individualShareholder;
public Object otherShareholder;
public ShareholderAddress shareholderAddress;
}
@Data
class ShareholderAddress{
public String uniqueIdentifier;
public Date startDate;
public Object endDate;
public Object careOf;
public String address1;
public String address2;
public String address3;
public Object address4;
public Object postCode;
public Object countryCode;
public Object addressType;
public Object pafId;
}
@Data
class IndividualShareholder{
public String firstName;
public String middleNames;
public String lastName;
public String fullName;
}
现在我想做一个简单的测试，在其中验证响应中特定键的值。在这种情况下，它是“numberOfShares”
"shareholding": {
"numberOfShares": 300,
"shareAllocation": [
这是我的测试：
package steps;
import lombok.var;
import io.restassured.response.Response;
import pojo.Shareholders;
import static org.hamcrest.MatcherAssert.assertThat;
import static org.hamcrest.Matchers.equalTo;
public class GetShareholderInformation {
public static void numberOfSharesReturned(Response response, int numberOfSharesReturned) throws Throwable {
System.out.println(response.getBody().prettyPrint());
int numberOfSharesRet = numberOfSharesReturned;
var shares = response.getBody().as(Shareholders.class);
assertThat(shares.getClass(), equalTo(numberOfSharesRet));
}
}
这是我运行测试时遇到的错误：

问题陈述：
- 从错误的角度来看，JSON 响应没有映射到 POJO 类。
- 在我的测试中，我不知道如何访问 Shareholders 类中的子类“Shareholding”，因为“Shareholding”是一个私有类。
