Java中的异步HTTP请求

Question

如何在不等待/读取响应的情况下在Java中发送异步HTTP GET / POST请求？我不想使用任何第三方库..

Answer 1

If you're not interested in reading the response at all you can just use URL.openStream() to create a connection and then immediately close the socket (or ignore it and let it time out, if you feel like being mean to the server). This isn't strictly asynchronous, but it will be quite a bit faster than any approach that relies upon fetching and parsing the server's response.

This can of course be made asynchronous by offloading the openStream() calls to another thread, either manually or by using the utilities available in java.util.concurrent .

Answer 2

java.util.concurrent can be used .

If you interested is using third party libraries then you might want to take a look at

Async Http Client

Answer 3

I would suggest using something like the Jetty HttpClient if you don't mind adding the Jetty libraries to your app. Here's a good example from Jetty's wiki page http://wiki.eclipse.org/Jetty/Tutorial/HttpClient .
