如何将值从ajax传递到portlet页面

function sendDataToPortlet() {
    var dataToSend = { key: "value" }; // 要发送的数据

    $.ajax({
        url: "<%= portletDisplay.getNamespace() %>yourPortletActionURL", // Portlet的动作URL
        type: "POST",
        data: JSON.stringify(dataToSend),
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function(response) {
            // 更新Portlet页面的内容
            $("#portletContent").html(response.data);
        },
        error: function(xhr, status, error) {
            console.error("AJAX请求失败: " + error);
        }
    });
}

private YourService yourService;

@Override
public void processAction(ActionRequest request, ActionResponse response) throws IOException, PortletException {
    // 检查是否是AJAX请求
    if (request.getParameter("ajax") != null && request.getParameter("ajax").equals("true")) {
        // 解析请求数据
        BufferedReader reader = request.getReader();
        Gson gson = new Gson();
        YourDataClass requestData = gson.fromJson(reader, YourDataClass.class);

        // 处理数据
        YourResponseData responseData = yourService.processData(requestData);

        // 设置响应内容类型
        response.setContentType("application/json");
        PrintWriter writer = response.getWriter();
        gson.toJson(responseData, writer);
    } else {
        // 处理非AJAX请求
        super.processAction(request, response);
    }
}
