Question

In the traditional way for every client request I get servlet response.
something like this:

HttpResponse response = client.execute(request)

Now I want to get updates from my servlet every time interval.
How can i catch the server s response?

比较一下,当我忙 the地工作时,《刑法》就是这样:

public void run()
{
    while(true)
    {            
        Object serverMessage = inStream.readObject();               
        // Do somthing with serverMessage
    }
}

Answer 1

You can simulate a server to client push with an approach called long polling, addressed here: Long Polling example
HTTP is a request driven protocol. You could explore other messaging protocols depending on what you re doing. Anything from Web Sockets to basic TCP, to a variety of frameworks that build ostensibly richer apis on top of tcp. What are you trying to accomplish?

Answer 2

页: 1 客户将不得不提出更多的要求,服务器——和服务器——然后是服务器。

然而(例如,Javascript)你可以尝试使客户在定期间隔中发出要求。
