如何使用GWT发布数据并重定向到其他页面？

当我按下按钮时，我会将一些数据发布到服务器，然后重定向到另一个页面。 我使用了RequestBuilder，但它正在等待响应，当然可以。没有任何反应，同一页面停留。我看到RequestBuidler不应该用在这里......我应该用什么来发布数据并能够重定向？

When I press a button I post some data to server and there redirect to another page. I used RequestBuilder but it is waiting the response, and of course get it. And nothing happens, same page stays. I see RequestBuidler shouldn't be used here... What should I use to post data and be able to redirect?

在Spring中

@RequestMapping(method=RequestMethod.POST, value="/ddd") public ModelAndView processOrder(@RequestBody String orderInString, HttpSession session) throws Exception{ ... return new ModelAndView(new RedirectView("abc")); }

在GWT中

In GWT

public void postData(final String data, final String url) { RequestBuilder builder = new RequestBuilder(RequestBuilder.POST, url); try { builder.sendRequest(data, new RequestCallback() { public void onError(Request request, Throwable exception) { ... } public void onResponseReceived(Request request, Response response) { if (200 == response.getStatusCode()) { .. } else { .. } } }); } catch (RequestException e) { ... } return; }

推荐答案

FormPanel form = new FormPanel("_self"); form.setMethod(FormPanel.METHOD_GET); Hidden params0 = new Hidden("param1", "value1"); Hidden params1 = new Hidden("param1", "value2"); Hidden params2 = new Hidden("param2", "value3"); FlowPanel panel = new FlowPanel(); panel.add(params0); panel.add(params1); panel.add(params2); form.add(panel); form.setAction(GWT.getModuleBaseURL() + "../MyServlet"); RootPanel.get().add(form); form.submit();

就是这样。该代码添加FormPanel并发送表单。

Thats it. The code adds FormPanel and sends form.
