JAVA：经过这么长时间后中断线程
我目前正在开发一个项目，要求我从 Internet 下载 WSDL 文件。
然而，我的问题之外的一切都很好......
我使用以下代码：
private Definition getDefinition(String url) throws WSDLException {
// Read the url and return an instance to a WSDL Definition
return WSDLFactory.newInstance().newWSDLReader().readWSDL(url);
}
这个 WSDLFactory 是一个线程（据我所知）。我遇到的问题是，在我提供的 URL 列表中，其中一些指向不再存在的 WSDL。这反过来又导致我的程序等待非常长的时间才意识到它应该抛出 FileNotFoundException。这是因为 WSDL 应该所在的位置需要很长时间才能返回 HTTP_RESPONSE 代码。
有没有办法可以将这个 WSDLFactory 包装成尝试获取 WSDL 但只给它 5-10 秒的时间？之后，它说“你已经有太多的时间来做这件事。我们正在超越你”？
I am currently working on a project that calls me to download a WSDL file from the internet.
Everything outside of my problem works great however...
I use the following code:
private Definition getDefinition(String url) throws WSDLException {
// Read the url and return an instance to a WSDL Definition
return WSDLFactory.newInstance().newWSDLReader().readWSDL(url);
}
This WSDLFactory is a Thread(to my knowledge). The issue I have is that in the list of URL's I provide, a few of them point to WSDL's that no longer exist. This in turn causes my program to wait an Extraordinarily long time before it realizes that it should throw a FileNotFoundException. This is caused because the location the WSDL should be at takes forever to return an HTTP_RESPONSE code.
Is there a way I can wrap this WSDLFactory into something that attempts to get the WSDL but only gives it 5-10 seconds to do so? After which, it says "You have had too much time to do this. We are stepping over you"?

查看 Executor 和 Futures 框架。
Look into the Executor and Futures frameworks.
如果可能，请设置底层套接字的超时
socket.setSoTimeout或通过库中的更高级别配置选项。否则（如果你的类路径上有 Google 的 guava）请尝试：
http://guava-libraries.googlecode.com/svn/trunk/javadoc/com/google/common/util/concurrent/TimeLimiter.html
Set the underlying socket's timeout if possible
socket.setSoTimeoutor via a higher-level config option in the library.Otheriwise (and if you've got Google's guava on the classpath) try:
http://guava-libraries.googlecode.com/svn/trunk/javadoc/com/google/common/util/concurrent/TimeLimiter.html
您可以尝试设置http超时
sun.net.client.defaultConnectTimeout。当然这取决于WSDLReader的实现检查这里：
网络属性
You can try setting the http timeout
sun.net.client.defaultConnectTimeout. Of course this depends on the implementation of WSDLReaderCheck here:
networking properties
使用辅助线程，它会在 5 秒后调用第一个线程的 Interrupt() 方法。在第一个线程中处理 InterruptedException。
Use a secondary thread, that calls the interrupt() method on the first thread after 5 seconds. Handle the InterruptedException in the first thread.
