如何在 java 中读取数据并将其放入模型中？

Question

我需要从休息中获取一些特定数据到我的模型。

我从休息中得到的数据：

[{"id":595,"name":"TransXChange20210805113332","prosystem_file_id":null,"dataset":16,"creator":113,"editor":113,"created":"2021- 08-05T09:45:21.444949Z","edited":"2021-08-05T09:45:27.542152Z","update_from_url":false,"description":"Rozkłady jazdy komunikacji miejskiej ważne od 08.08.2021","文件":"https://otwartedane.erzeszow.pl/media/resources/transxchange20210805113332.xml","链接":null,"extension":"XML","data_type":"[]","file_name": "transxchange20210805113332.xml","chart_info":null,"map_info":null,"score":4,"public":true,"licence":"other-open","connection_dict":null,"selection_string": null,"db_type":"POSTGRESQL","type":"file","dbview_cache_minutes":1,"preview_base64":null,"gpkg_display_info":null,"archive_to_csv":false},{"id":538, "name":"TransXChange20210513082611","prosystem_file_id":null,"dataset":16,"creator":113,"editor":113,"created":"2021-05-13T06:28:50.233464Z","已编辑":"2021-07-28T08:52:06.695966Z","update_from_url":false,"description":"Rozkłady jazdy komunikacji miejskiej wa日期 15.05.2021","file":"https://otwartedane.erzeszow.pl/media/resources/transxchange20210513082611.xml","link":null,"extension":"XML","data_type":" []","file_name":"transxchange20210513082611.xml","chart_info":null,"map_info":null,"score":4,"public":true,"licence":"other-open","connection_dict ":null,"selection_string":null,"db_type":"POSTGRESQL","type":"file","dbview_cache_minutes":1,"preview_base64":null,"gpkg_display_info":null,"archive_to_csv":false} ,{"id":544,"name":"TransXChange20210526143716","prosystem_file_id":null,"dataset":16,"creator":113,"editor":113,"created":"2021-05-26T12 :40:42.587492Z","edited":"2021-07-28T08:52:04.417450Z","update_from_url":false,"description":"Rozkłady jazdy komunikacji miejskiej ważne od 01.06.2021","file": "https://otwartedane.erzeszow.pl/media/resources/transxchange20210526143716.xml","link":null,"extension":"XML","data_type":"[]","file_name":"transxchange20210526143716。 xml","chart_info":null,"map_info":null,"score":4,"public":true,"licence":"其他r-open","connection_dict":null,"selection_string":null,"db_type":"POSTGRESQL","type":"file","dbview_cache_minutes":1,"preview_base64":null,"gpkg_display_info":null ,"archive_to_csv":false}]

我在一行中得到它

我的java代码：

RestTemplateBuilder builder = new RestTemplateBuilder();
        String soc = builder.build().getForObject("https://otwartedane.erzeszow.pl/v1/datasets/16/resources/", String.class);
        assert soc != null;
        System.out.println(soc);

问题是我需要将它们放入模型中

我的模特：

public class Resource {

private long id;
private String name;
private long prosystem_file_id;
private int dataset;
private int creator;
private int editor;
private LocalDateTime created;
private LocalDateTime edited;
private boolean update_from_url;
private String description;
private String file;
private String link;
private String extension;
private String data_type;
private String file_name;
private String chart_info;
private String map_info;
private int score;
private boolean isPublic;
private String licence;
private String connection_dict;
private String selection_string;
private String db_type;
private String type;
private int dbview_cache_minutes;
private String preview_base64;
private String gpkg_display_info;
private boolean archive_to_csv;

所有的 getter 和 setter 都会生成。 如何将它们放入模型中，例如列表？ 问题是我得到像 [{resource},{resource},{resource}] 这样的数据。

Answer 1

正如 RestTemplate documentation 所述

您可以调用 getForObject 方法，将所需的反序列化类作为参数传递。

类似：

RestTemplateBuilder builder = new RestTemplateBuilder();

Resource soc = builder.build().getForObject("https://otwartedane.erzeszow.pl/v1/datasets/16/resources/", Resource.class);
assert soc != null;
System.out.println(soc);

Answer 2

我找到了问题的答案。

我需要将我的调用分配给模型数组。

Resource[] soc =builder.build().getForObject( URL , Resource[].class );
