如何在数组中声明新字段

Question

我的传输类看起来像这样：

private long fromTimestamp;
private long toTimestamp;
private Integer variableId;
private Integer typeId;
private boolean time;
private String period;
private Object[] columns = {variableId, typeId, time, period};

Class在我的Controller中用作RequestBody，我不需要字段variableId，typeId，time和period。它应该只在一个数组中。

当我将参数放在JSON中时没有意义：

{
"fromTimestamp": 0,
"toTimestamp": 10,
"variableId": 1, 
"typeId": 1, 
"time": false, 
"period": null,
"columns": [{
    "variableId": 1, 
    "typeId": 1, 
    "time": false, 
    "period": null
}]

如何直接在名为columns的数组中声明新fild？

为什么不使用这样的东西：

public class Transport {
    private long fromTimestamp;
    private long toTimestamp;
    private Column[] column;
    ...
}

public class Column {
    private Integer variableId;
    private Integer typeId;
    private boolean time;
    private String period;
    ...
}
