I have one GET Restful service that return JSON. I have to get Response time of that service. My requirement is that when i try to get JSON data from that service and if that service take more than 10 seconds then i have to redirect it some another page. So how can i do this?

My code is given below

import java.net.URL;
import java.net.HttpURLConnection;

URL url = new URL(sURL);
HttpURLConnection req = (HttpURLConnection) url.openConnection();
req.connect();

if (req.getResponseCode() == HttpURLConnection.HTTP_OK) {
    System.out.println("ResponseCode = HTTP_OK");
}

First set timeout and then catch the timeout exception and make a new request:

try {
    req.setConnectTimeout(TimeUnit.SECONDS.toMillis(10)); 
    req.setReadTimeout(TimeUnit.SECONDS.toMillis(10));

    [...] readData(req);

} catch (SocketTimeoutException e) {
    // do request again
}

Edit: readTimeout is optional. I'm using it always bacause I want wait too long for data.

firstly you want to setReadTimeout or setConnectTimeout in url request and catch java.net.SocketTimeoutException then in catch redirect to your new url as the code below 

import java.net.URL;
import java.net.HttpURLConnection;
try {
     URL url = new URL(sURL);
     HttpURLConnection req = (HttpURLConnection) url.openConnection();
     req .setReadTimeout(10000); // 10 seconds
       if (req.getResponseCode() == HttpURLConnection.HTTP_OK) {
            System.out.println("ResponseCode = HTTP_OK");
         }
    } catch (java.net.SocketTimeoutException e) {
        req = (HttpURLConnection) new URL("your new URL").openConnection();
   }

long start = System.currentTimeMillis();   
chain.doFilter(request, response);
long elapsedTime = System.currentTimeMillis() - start;

if(elapsedTime <= 10){
    System.out.println("ResponseCode = HTTP_OK");
}

check elapsedTime less then or equal to 10 or not, here request and respone is from ServletRequest and ServletResponse

HttpURLConnection has a setConnectTimeout method.

You can use it and catch the SocketTimeoutException, then you can redirect to the other page you want.

Edit

If you want the response anyway, and the duration also, you can take the current system time juste before the call, then after response compare the time that your request took.
