Java 如何在Apache http客户端中设置连接超时？

我想使用运行线程安全的异步HTTP请求。我注意到它不尊重我的

CONNECTION\u TIMEOUT

参数

代码是ColdFusion/Java混合的

client = loader.create("org.apache.http.impl.nio.client.DefaultHttpAsyncClient").init();
CoreConnectionPNames = loader.create("org.apache.http.params.CoreConnectionPNames");

client.getParams()
      .setIntParameter(JavaCast("string", CoreConnectionPNames.SO_TIMEOUT), 10)
      .setIntParameter(JavaCast("string", CoreConnectionPNames.CONNECTION_TIMEOUT), 10);

client.start();

request = loader.create("org.apache.http.client.methods.HttpGet").init("http://www.google.com");
future = client.execute(request, javacast("null", ""));

try {
   response = future.get();
}
catch(e any) {}

client.getConnectionManager().shutdown();

不管我为连接超时提供了什么，请求总是返回200 OK。检查下面的输出

连接超时有什么作用吗

输出

apache的HttpClient的文档有点零碎。在您的设置中尝试此选项（在版本4中对我有效）：

必须使用框架的类方法定义HttpParams对象

        HttpParams params = new BasicHttpParams();
        HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
        HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
        HttpConnectionParams.setConnectionTimeout(params, 2000);

        SchemeRegistry registry = new SchemeRegistry();
        registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
        registry.register(new Scheme("https", SSLSocketFactory.getSocketFactory(), 443));

        ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);

        HttpClient client = DefaultHttpClient(ccm, params);

谢谢我正在试用你的代码，但是要把它翻译成CF需要额外的工作。对我来说太简单了。在前两个示例中，linse

HTTPConnectionParams

引用了我需要创建的对象。Porbably

org.apache.http.params.

但是您提供给

setConnectionTimeout

的

params

参数来自哪里？我不能在那里抛出它，否则它会抛出一个

params is undefined

错误。。。如果这听起来很迟钝，很抱歉，但是使用java/CF混合代码是乏味的。另外，是否需要SchemeRegistry对象，我可以不使用它吗；这里有更多信息：javadoc在这里：

        HttpParams params = new BasicHttpParams();
        HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
        HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
        HttpConnectionParams.setConnectionTimeout(params, 2000);

        SchemeRegistry registry = new SchemeRegistry();
        registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
        registry.register(new Scheme("https", SSLSocketFactory.getSocketFactory(), 443));

        ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);

        HttpClient client = DefaultHttpClient(ccm, params);
