带循环弹簧的自定义 Json

Question

在这种情况下，我使用的是弹簧靴。和 Rest 控制器返回数据。

这是我现在使用 crudrepository 从数据库中获得的 JSON：

{
   forms: [
           {
            paent: "",
            posx: 1,
            fieldname: "CostCenter",
            posy: 1,
            ishidden: false,
            level: 0,
            recordname: "CostCenter",
            isrequired: true,
            inputtype: "text",
            issearchable: true,
            label: "Cost Center",
            seq: "1",
            isenabled: false
           },
          {
           parent: "CostCenterDetail",
           ishidden: false,
           level: 1,
           recordname: "CostCenter",
           isrequired: true,
           inputtype: "text",
           issearchable: false,
           label: "Description",
           posx: 1,
           fieldname: "Description",
           posy: 2,
           seq: "5",
           isenabled: true
          },
          {
           parent: "CostCenterDetail",
           ishidden: false,
           level: 1,
           recordname: "CostCenter",
           isrequired: false,
           inputtype: "text",
           issearchable: false,
           label: "Created User",
           posx: 1,
           fieldname: "CreateUserID",
           posy: 4,
           seq: "6",
           isenabled: false
          },
          {
           parent: "CostCenterDetail",
           ishidden: false,
           level: 1,
           recordname: "CostCenter",
           isrequired: false,
           inputtype: "date",
           issearchable: false,
           label: "Created User",
           posx: 2,
           fieldname: "CreateDate",
           posy: 4,
           seq: "7",
           isenabled: false
          },
          {
           parent: "CostCenterDetail",
           ishidden: false,
           level: 1,
           recordname: "CostCenter",
           isrequired: false,
           inputtype: "date",
           issearchable: false,
           label: "Created User",
           posx: 2,
           fieldname: "UpdateDate",
           posy: 5,
           seq: "9",
           isenabled: false
          },
          {
           parent: "CostCenterDetail",
           ishidden: false,
           level: 1,
           recordname: "CostCenter",
           isrequired: true,
           inputtype: "date",
           issearchable: false,
           label: "Effective Date",
           posx: 1,
           fieldname: "Effdt",
           posy: 1,
           seq: "3",
           isenabled: true
          },
          {
           posx: 1,
           fieldname: "CostCenterDetail",
           posy: 2,
           ishidden: false,
           level: 0,
           recordname: "Dummy",
           isrequired: false,
           inputtype: "scroll",
           issearchable: false,
           label: "Cost Center Detail",
           seq: "2",
           isenabled: true
          },
          {
           parent: "CostCenterDetail",
           ishidden: false,
           level: 1,
           recordname: "CostCenter",
           isrequired: false,
           inputtype: "text",
           issearchable: false,
           label: "Created User",
           posx: 1,
           fieldname: "UpdateUserID",
           posy: 5,
           seq: "8",
           isenabled: false
          },
          {
           parent: "CostCenterDetail",
           ishidden: false,
           level: 1,
           recordname: "CostCenter",
           isrequired: true,
           inputtype: "text",
           issearchable: false,
           label: "Status",
           posx: 2,
           fieldname: "Status",
           posy: 1,
           seq: "4",
           isenabled: true
           }
        ]
}

这就是问题所在。我想在我的控制器上循环我的 json，所以每次我发现我的“级别”正在改变我需要添加这个“[]”所以我的“级别：1”数据将在一个新数组中。

例子：

{
  forms : [
            {
              level:0,
              ---data--
                       [ {
                           level : 1,
                           --- data---
                         }
                       ]
             }
          ]
}

这是我的休息控制器：

@RequestMapping(value = "/alltable" ,method = RequestMethod.GET,  produces = MediaType.APPLICATION_JSON_VALUE)
    @ResponseStatus(value = HttpStatus.OK)
    public String test() {  
        JSONObject outerObject = new JSONObject();
        outerObject.put("forms", pspnlRepository.findAll());

        return outerObject.toString();
    }

如何遍历我的 json 并在我的 json 中添加一个新数组？ 任何帮助都会非常有用 谢谢！

这是我的存储库代码：

public interface pspnlRepository extends CrudRepository<pspnlfield, Long>{


    Iterable<pspnlfield> findAll();
}

试试这个：

@RequestMapping(value = "/alltable" ,method = RequestMethod.GET,  produces = MediaType.APPLICATION_JSON_VALUE)
    @ResponseStatus(value = HttpStatus.OK)
    public String test() {  
        JSONObject outerObject = new JSONObject();
        List<Object> pspnlfields=Lists.ArrayList(pspnlRepository.findAll());
        //you can loop here on pspnlfields and add what you want 
        // then put the edited list to your outerObject
        outerObject.put("forms", pspnlfields);

        return outerObject.toString();
    }
