我正在尝试进行一些服务器/套接字编程。服务器代码是在Ubuntu机器上用纯Java编写的。客户端代码是为我的LG Thrill编写的。服务器似乎工作正常。我通过编写一个简单的测试客户端来测试服务器，该客户端基本上使用带有"localhost" IP的try/catch块。我通过从手机ssh到服务器机器来检查IP是否可达（是的，它是可达的）。
我的服务器代码如下：
package org.vsector.server;
import java.io.IOException;
import java.net.ServerSocket;
public class SceneFlowServer {
int port;
Thread running = null;
CameraHandler handler = null;
public SceneFlowServer( int port, CameraHandler handler ){
this.port = port;
this.handler = handler;
}
public void start(){
if( handler == null ) return;
try{
running = new Thread(){
public void run(){
try{
ServerSocket listen = new ServerSocket( port );
while( true ){
System.out.print( "I am waiting on port " + port + "... " );
handler.accept( listen.accept() );
System.out.println( "Got someone!" );
Thread spinoff = new Thread( handler );
spinoff.start();
}
}catch( IOException e ){
System.err.println( "Could not listen on port " + port + "!" );
System.err.flush();
return;
}
}
};
running.start();
running.join();
}catch( Exception e ){
System.err.println( "Could not start thread!" );
System.err.flush();
}
}
}
我的CameraHandler代码：
package org.vsector.server;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.Socket;
public class CameraHandler implements Runnable {
Socket client = null;
public CameraHandler(){ }
public void accept( Socket client ){
this.client = client;
}
@Override
public void run() {
// TODO Auto-generated method stub
BufferedReader in;
try {
in = new BufferedReader( new InputStreamReader( client.getInputStream() ));
System.out.println( in.readLine() );
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
client.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
我的客户端代码如下：
package org.vsector.client;
import java.io.PrintWriter;
import java.net.InetSocketAddress;
import java.net.Socket;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class ProcessingClientActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView text = (TextView) findViewById( R.id.textBox );
Socket sock;
try {
text.append( "\nOpening and writing to socket... " );
sock = new Socket();
sock.connect( new InetSocketAddress( "some ip", 4444 ), 30000 );
PrintWriter out = new PrintWriter( sock.getOutputStream(), true );
out.println( "Hello!" );
out.close();
sock.close();
text.append( "Done!" );
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
text.append( "Error: " + e + "\n" );
text.append( e.getMessage() );
}
}
}
权限已设置，但仍出现“错误：java.net.SocketTimeoutException：连接超时。”
我无法弄清是什么原因导致的！有任何想法吗？
编辑：
算了。网络问题。我在家庭网络上运行代码，一切正常。
