我在java中使用Jtidy解析器。这是我的代码......
URL url = new URL("www.yahoo.com");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
InputStream in = conn.getInputStream();
Tidy tidy = new Tidy();
Document doc = tidy.parseDOM(in, null);
当我来到这个语句Document doc = tidy.parseDOM(in, null);
时,解析页面需要花费太多时间,所以我想设置文档对象的时间限制。请帮帮我,如何设定时间。

您可以使用java.util.Executors
框架并向其提交有时间限制的任务。
这里有一些代码可以证明这一点:
// Note that these variables must be declared final to be accessible to task
final InputStream in = conn.getInputStream();
final Tidy tidy = new Tidy();
ExecutorService service = Executors.newSingleThreadExecutor();
// Create an anonymous class that will be submitted to the service and returns your result
Callable<Document> task = new Callable<Document>() {
public Document call() throws Exception {
return tidy.parseDOM(in, null);
}
};
Future<Document> future = service.submit(task);
// Future.get() offers a timed version that may throw a TimeoutException
Document doc = future.get(10, TimeUnit.SECONDS);
