处理数据时渲染视图 [英] Render view while processing data

问题描述

我使用的是Play框架2.5.14，可以玩Java.

I'm on Play Framework 2.5.14, with play for java.

我有一个可加载和处理某些数据的服务，并且处理该数据需要很长时间.

I have a Service that loads and processes some data, and it takes a long time to process that data.

我正在这样做:

Controller

public Result showData() {
    List<Data> data = service.getProcessedData();

    return ok(views.html.data.render(data));
}

View

@(data: List[Data])

<!-- html code -->

但是当我转到页面时，它很空白，因为service.getProcessData()花费的时间太长.函数完成后，将呈现视图.

But when I go to the page it is in blank a long time because service.getProcessData() takes too long. When the function finish, then the view is rendered.

我需要加载视图，并在数据准备好后填充视图.

What I need is for the view to load and when the data is ready, fill the view.

推荐答案

就像我在评论中说的那样，我没有找到使用Play的解决方案.

Like I said in comments, I did not find a solution using Play.

我要做的是渲染视图，并在视图本身中用javascript/jquery调用ajax请求以获取慢速数据.

What I do is to render the view, and in the view itself I call an ajax petition in javascript/jquery to get the slow data.

希望这会有所帮助，这是我唯一喜欢的解决方案.

Hope this can help, it is the only solution that I liked.
