java - 将泛型类型的Json转换为特定的Json格式

Question

我正在使用 Java 8，并且尝试使用“Collectors.groupingBy”，但尚未获得所需的格式

public class ConsigneeLoadDetails {

    private Integer tripID;
    private String consignor;
    private String consignee;
    private String city;
    private Double distanceToNext;
    private Double load;
    private Integer cap;
    private Integer vehicleCapacity;
    private Double cLoad;
    private Integer truckUtilisation;
    private Double latitude;
    private Double longitude;  

    // getter , setter of all parameters 
}



List<ConsigneeLoadDetails> listConsigneeLoadDetails = new ArrayList();

// loop to add ConsigneeLoadDetails

listConsigneeLoadDetails.add(consigneeLoadDetails);

我的 API 响应低于 Json

我想要以下格式的回复

Answer 1

为什么不重新安排你的 POJO 类，就像这样

public class ConsigneeLoadDetails {

    private Integer tripID;
    private String consignor;
    private Integer vehicleCapacity;
    private Double cLoad;
    private Integer truckUtilisation;
    private List<consigneeDetails> consigneeDetails    
    private Double latitude;
    private Double longitude;  

    // getter , setter of all parameters 
}

public class ConsigneeDetails {

    private String consignee;
    private String city;
    private Double distanceToNext;
    private Double load;
    private Integer cap;

    // getter , setter of all parameters 
}
