Java 如何使用gson库形成json，以使对象、列表之间有循环？

我是Java新手，因为我的背景是JavaScript。 输入是通过jsp页面输入的，它们的值被提供给json请求。 我有如下所示的dto对象，使用它我必须形成json，使用Java中的gson库将其作为请求发送给postman。 现在我能够形成请求，但并不完全是不知道，如果有更好的方法来处理我在下面共享的代码，我想知道如何使用不同的

visibilityInfo

数组来循环

visibilityType

，因为json请求在请求中会有它们的数组

请参阅下面的dto对象和包含代码的主类

MainClass.java:

            List<String> accountNumbers = new ArrayList<>();
            accountNumbers.add("1233");
    accountNumbers.add("2234");         
            VisibilityInfo vi = new VisibilityInfo();
            vi.setVisibilityType(VisibilityType.THIRD_PARTY);
            vi.setAccountNumbers(accountNumbers);
            vi.setReceivingAddress(addr);
            List<VisibilityInfo> visibilityInfo = new ArrayList<>();        
            visibilityInfo.add(vi); 
             scv.setEnroleeName(Values.enroleeName);
             scv.setVisibilityInfo(visibilityInfo);
             scv.setCompanyName(Values.companyName);

            String jsonStr = gsonObj.toJson(nr);
            System.out.println(jsonStr);
        }
    } 

Address.java

AddressType.java

预期结果：需要添加代码，根据

VisibilityType

，循环

VisibilityInfo

，如预期结果所示

{ 
  "transactionId": "12334567", 
  "clientId": "PPP", 
  "destinationAddress": "xyz@ggg.com", 
  "sendConfirmationNotification": { 
    "enroleeName": "Dev User 992", 
    "visibilityInfo": [ 
      { 
        "visibilityType": "FOURTH_PARTY", 
        "accountNumbers": [ 
          "1233", 
          "6722" 
        ], 
        "receivingAddress": null 
      }, 
      { 
        "visibilityType": "OUTBOUND", 
        "accountNumbers": [ 
          "6152", 
          "1277" 
        ], 
        "receivingAddress": null 
      }, 
      { 
        "visibilityType": "INBOUND", 
        "accountNumbers": null, 
        "receivingAddress": { 
          "addressType": "PPP_Store", 
          "addressLine1": null, 
          "addressLine2": null, 
          "addressLine3": null, 
          "politicalDivision": null, 
          "city": "downtown test", 
          "state": "NY", 
          "zipcode": "7539", 
          "country": "US", 
          "phoneNumber": null 
        } 
      } 
    ], 
    "companyName": "Clent_companyName", 
    "nickName": "DXXX1",

    "cvURL": "http://www.google.com/test/sampleURL" 
  }, 
  "locale": "en_US",

获得的实际结果：

你能帮我写一个有效的代码，并将基于

VisibilityType

到

VisibilityInfo

的对象数组添加到创建的json对象中。

我建议你为每个类创建一个构造函数，该构造函数包含所有必需的值。这样，您可以用更少的代码创建对象

MainClass.java:

  import java.util.ArrayList;
  import java.util.List;
  import com.google.gson.Gson;
  import com.xxx.nsp.constants.Values;
  import com.xxx.nsp.dto.Address;
  import com.xxx.nsp.dto.SendCVConfirmationNotification;
  import com.xxx.nsp.dto.VisibilityInfo;
  import com.xxx.nsp.dto.VisibilityType;
  import com.xxx.nsp.json.NSPNotificationRequest;
  public class MainClass {
      public static void main(String[] args) {  

          Address addr = new Address(Values.addressType, Values.addressLine1, 
            Values.addressLine2, Values.addressLine3, Values.politicalDivision,
            Values.city, Values.state, Values.zipcode, null, Values.phoneNumber);

          List<String> accountNumbers = new ArrayList<>();
          accountNumbers.add("1233");
          accountNumbers.add("2234");

          List<VisibilityInfo> visibilityInfo = new ArrayList<>();        
          visibilityInfo.add(new VisibilityInfo(VisibilityType.THIRD_PARTY,
            accountNumbers, addr));  

          SendCVConfirmationNotification scv = new SendCVConfirmationNotification(
            Values.enroleeName, Values.companyName, Values.nickName, visibilityInfo, 
            Values.hasClaims, Values.hasReturns, Values.cvURL, null); 

          NSPNotificationRequest nr = new NSPNotificationRequest(Values.transactionId,
            Values.clientId, Values.destinationAddress, scv, Values.locale,
            Values.mediaType, Values.pageId);

          Gson gsonObj = new Gson();
          String jsonStr = gsonObj.toJson(nr);
          System.out.println(jsonStr);
      }
  } 

public enum VisibilityType {
    INBOUND,
    OUTBOUND,
    FOURTH_PARTY,
    THIRD_PARTY;
}

 public static void main(String[] args) {  

      List<VisibilityInfo> visibilityInfo = new ArrayList<>(); 

      List<String> accountNumbers = new ArrayList<>();
      accountNumbers.add("1233");
      accountNumbers.add("6722");       
      visibilityInfo.add(new VisibilityInfo(VisibilityType.FOURTH_PARTY,
        accountNumbers, null));

      List<String> accountNumbers = new ArrayList<>();
      accountNumbers.add("6152");
      accountNumbers.add("1277");       
      visibilityInfo.add(new VisibilityInfo(VisibilityType.OUTBOUND,
        accountNumbers, null));

      Address addr = new Address(Values.addressType, null, 
        null, null, null, "downtown test", "NY", "7539", "US", null);    
      visibilityInfo.add(new VisibilityInfo(VisibilityType.OUTBOUND,
        null, addr));

      SendCVConfirmationNotification scv = new SendCVConfirmationNotification(
        Values.enroleeName, Values.companyName, Values.nickName, visibilityInfo, 
        Values.hasClaims, Values.hasReturns, Values.cvURL, null); 

      NSPNotificationRequest nr = new NSPNotificationRequest(Values.transactionId,
        Values.clientId, Values.destinationAddress, scv, Values.locale,
        Values.mediaType, Values.pageId);

      Gson gsonObj = new Gson();
      String jsonStr = gsonObj.toJson(nr);
      System.out.println(jsonStr);
  }

将此添加到NSNotificationRequest：

public NSPNotificationRequest(String transactionId, String clientId,
  String destinationAddress, SendCVConfirmationNotification sendCVConfirmationNotification,
  String locale, String mediaType, String pageId){
    this.transactionId = transactionId;
    this.clientId = clientId;
    this.destinationAddress = destinationAddress;
    this.sendCVConfirmationNotification = sendCVConfirmationNotification;
    this.locale = locale;
    this.mediaType = mediaType;
    this.pageId = pageId;
    //if this class includes any other properties, include them accordingly
}

如果我犯了一个错误或误解了你的问题，告诉我，我会设法解决

以下是一些提示：

• 尽量发布不太一般的问题和需要较少代码的更具体的问题
• 查看Java文档、构造函数、数据类型等
• 不要使用那么多枚举。在某些情况下，它们有意义（VisibilityType），而在某些情况下它们没有意义（值）

编辑：

要获得指定的预期结果，必须编辑VisibilityType和主方法：

如果我犯了一个错误或误解了你的问题，告诉我，我会设法解决

以下是一些提示：

• 尽量发布不太一般的问题和需要较少代码的更具体的问题
• 查看Java文档、构造函数、数据类型等
• 不要使用那么多枚举。在某些情况下，它们有意义（VisibilityType），而在某些情况下它们没有意义（值）
