Installation Instructions
Here you can find instructions on how to install Subversive using different types of Subversive distributions.
Introduction
The Subversive (SVN) installation consists of installing the Subversive plug-in and a Subversive SVN Connector. The Subversive plug-in is developed as an Eclipse official project with an EPL license and is distributed from the Eclipse website. A Subversive SVN Connector uses a SVN library to communicate with SVN repositories. Currently, there is only the connector which uses the SVNKit library. This library is developed as open-source project, but since its license is not EPL-compatible, the whole connector has to be distributed from an external website.
In order to use Subversive, you have to install the Subversive plug-in and the connector that is compatible with your operating system (OS) and the used SVN version.
Phase 1 - Installation of the Subversive Plug-In
You can install Subversive using its online or archived update site.
Run Eclipse and select Help > Install New Software... from the main menu.
In the Install dialog that appears, press the Add... button and specify the path to an online or archived Subversive update site, e. g. https://download.eclipse.org/technology/subversive/4.8/release/latest/. If you need a specific version, have a look at the Downloads page.
Select the required Subversive features to install and follow the standard plug-in installation procedure. Reboot Eclipse after installation is complete.
Follow the instructions below to install Subversive connectors.
Phase 2 - Installation of Subversive SVN Connectors
Once the Subversive plug-in is installed and Eclipse is rebooted, Subversive automatically displays the dialog that shows Subversive SVN Connectors compatible with the installed version of the plug-in. Alternatively, you can install Subversive SVN Connectors from online and archived update sites for connectors.
Run Eclipse and select Help > Install New Software... from the main menu.
In the Install dialog that appears, press the Add... button and enter the URL of the following update site: https://osspit.org/eclipse/subversive-connectors/.
Select the required features to install and follow the standard plug-in installation procedure. Reboot Eclipse after installation is complete.

Finding - 2 different ways to get result from API to showing by using Datatables.net

As of 2023Feb07_1503 - failed to achieve by method of: data: data

Published on

My html table:

<table id="listaVideos2" class="display">
        <thead>
        <tr>
            <th>nombre</th>
            <th>descripcion</th>
            <th>codigoYoutube</th>
            <th>bpm</th>
        </tr>
        </thead>
    </table>

My JavaScript:

$.ajax({
        "url": "listado2",
        "type": "GET",
        "datatype": 'json',
        "success": function (data) {
            $('#listaVideos2').DataTable({
                "fixedHeader" : true,
                "paging":   false,
                "info":     true,
                "autoWidth": true,
                "order": [],
                data: data,
                select: true,
                columns: [
                    { "data": "nombre" },
                    { "data": "descripcion" },
                    { "data": "codigoYoutube",
                        "title": "Youtube",
                        "orderable": false
                    },
                    { "data": "bpm" },
                ]
            });
        }
    });

or another way you can use:

$('#listaVideos2').DataTable({
        "fixedHeader" : true,
        "paging":   false,
        "info":     true,
        "autoWidth": true,
        "order": [],
        ajax: {
            url: 'listado2',
            dataSrc: ''
        },
        select: true,
        columns: [
            { "data": "nombre" },
            { "data": "descripcion" },
            { "data": "codigoYoutube",
                "title": "Youtube",
                "orderable": false
            },
            { "data": "bpm" },
        ],
        buttons: [
            { extend: "create", editor: editor },
            { extend: "edit",   editor: editor },
            { extend: "remove", editor: editor }
        ],
        dom: "Bfrtip",
    });

And my Controller: (if your controller is a @RestController I think you wouldn't need the @ResponseBody)

@GetMapping("/listado2")
    @ResponseBody
    public List<Video> apiListadoVideos() {
        return videosServicio.buscarTodosLosVideos();
    }

where my Video class is this simple (I just remove de getters, setters...):

public class Video {
    private Integer id;
    @NotEmpty
    @NotBlank
    private String nombre;
    private String descripcion;
    @NonNull @NotBlank
    private String codigoYoutube;
    private String bpm;
    private Categoria categoria;
    private Tono tono;
    private Modo modo;
}
