我已经实现了一个DataTable配置，每行都有一个删除按钮。然而，删除按钮的功能仅限于具有特定角色的用户，例如“ADMIN”。没有“ADMIN”或“EDITOR”角色的用户在尝试使用删除按钮时会遇到一个提示，通知他们未经授权的访问。
这是一个按钮，它被呈现在我的DataTable列中：

<form style="display:inline !important;" action="/admin/delete/" method="post" onsubmit="return confirm('Do you really want to delete employee ${row.id} ?');">
<input type="hidden" name="id" value="${row.id}" />
<button class="form-command btn btn-danger btn-sm" type="submit"><i class="fa fa-trash-o"></i></button>
</form>`;

字符串
这是控制器类中的删除API：

@PreAuthorize("hasRole({'ROLE_ADMIN', 'ROLE_EDITOR'})")
    @DeleteMapping("delete")
    @ResponseStatus(HttpStatus.OK)
    void delete(@RequestBody Integer id) {
        deleteEntity(id);
    }

@PreAuthorize注解应该检查经过身份验证的用户的角色，如果他们没有被授权，则拒绝他们。事情是这样的，我想向前端用户发送一条消息，告诉他们他们没有删除行的权限。

$(document).ready(function () {
    $('#tableID').DataTable({
        "processing": true,
        "serverSide": true,
        "ajax": {
            "url": "api-endpoint",
            "type": "POST",
            'beforeSend': function (xhr) {
                xhr.setRequestHeader(csrfHeader, csrfToken);
            },
            'data': function (d) {
                d.search.value = d.search.value || '';
                d.columns[2]['search']['value'] = d.columns[2]['search']['value'] || '';
                d.columns[3]['search']['value'] = d.columns[3]['search']['value'] || '';
                d.columns[4]['search']['value'] = d.columns[4]['search']['value'] || '';
            },
        },
        "columns": [
            // ... (other columns remain unchanged)
        {
                    "data": null,
                    "render": function (data, type, row) {
                        let dropdownMenu = ``;
                        let deleteForm = `
                        <form style="display:inline !important;" action="/admin/delete/" method="post" onsubmit="return confirm('Do you really want to delete employee ${row.id} ?');">
                            <input type="hidden" name="id" value="${row.id}" />
                            <button class="form-command btn btn-danger btn-sm" type="submit"><i class="fa fa-trash-o"></i></button>
                        </form>`;
                        return dropdownMenu + "<br/>" + deleteForm;
                    },
                    "orderable": false
                }
            
        ],
        initComplete: function () {
            // ... (unchanged)
        }
    });
});

我如何才能做到这一点？
