I tried the following code:
final AsyncContext async = req.startAsync();
async.setTimeout(30000);
async.addListener(new AsyncListener(){
@Override
public void onComplete(AsyncEvent event) throws IOException {
System.out.println(Thread.currentThread()+"onComplete");
}
@Override
public void onTimeout(AsyncEvent event) throws IOException {
System.out.println(Thread.currentThread()+"onTimeout");
}
@Override
public void onError(AsyncEvent event) throws IOException {
System.out.println(Thread.currentThread()+"onError
"+event.getThrowable());
}
@Override
public void onStartAsync(AsyncEvent event) throws IOException {
System.out.println(Thread.currentThread()+"onStartAsync");
}
});
async.start(new Runnable(){
@Override
public void run() {
try {
async.getResponse().getWriter().write("22222");
async.getResponse().getWriter().flush();
System.out.println(Thread.currentThread()+"run");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
The output:
Thread[http-bio-80-exec-4,5,main]run
Thread[http-bio-80-exec-5,5,main]onTimeout
Thread[http-bio-80-exec-5,5,main]onError null
Thread[http-bio-80-exec-5,5,main]onComplete
Although the Runnable writes some content. The onTimeout method is still
invoked.
