Question

当我按下按钮时，我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，当然得到它。没有任何反应，同一页留下来。我看到不应该在这里使用RequestBuidler ...我应该使用什么来发布数据并能够重定向？

在春天

@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

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;
}

Answer 1

    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();

多数民众赞成。代码添加FormPanel并发送表单。

添加更多规格，代码，这很模糊。既然你使用的是Spring-mvc，你应该有类似的东西

 private static final String newPage = "index2";  //this is resolved with view resolver
 @RequestMapping(params = "action=button")
 protected String getALPLicense(final RenderRequest request,
            final RenderResponse response, final Model model) throws Exception {
 try{
 }catch{
 }
 return newPage;  //this is your new redirected page
 }

如何使用GWT发布数据并重定向到另一个页面？
