Question

我正在尝试连接客户端服务器，在打开连接时遇到以下错误：

java.net.ConnectException: errno: 110 (Connection timed out), error: 
Connection timed out (local port XXXXX to address 0:0:0:0:0:0:0:0, remote 
port XXXX to address XXX.XXX.XXX.XX)

代码段：

URL url = new URL("http://XXX.XXX.XXX.XX:XXXX/services/ServiceEngine");

HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/json");

OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream());
writer.write(json);
writer.close();
BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String line;
while ((line = br.readLine()) != null) {
  jsonString.append(line);
}
br.close();
connection.disconnect();

当服务器在预定时间段内无法响应并且与代码中的逻辑关系不大时，就会发生连接超时。

您可以使用HttpURLConnection.setConnectTimeout（）更改此时间段，如下所示：

connection.setConnectTimeout(10000); //Time is set in milliseconds, so 1000 is 1 second.

正如另一位用户指出的那样，这可能是您的服务器尚未真正启动并准备好托管连接。

java.net.ConnectException：错误号：110（连接超时）
