要增加apache SSHD的scpClient的ChannelOutputStream因为SocketTimeoutException的等待超时时间,可以通过以下步骤实现:
下面是一个示例代码:
import org.apache.sshd.client.channel.ChannelOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.net.Socket;
import java.net.SocketTimeoutException;
public class CustomChannelOutputStream extends ChannelOutputStream {
private static final int TIMEOUT = 5000; // 设置超时时间为5秒
public CustomChannelOutputStream(Socket socket) throws IOException {
super(socket);
socket.setSoTimeout(TIMEOUT); // 设置Socket超时时间
}
@Override
public void write(int b) throws IOException {
try {
super.write(b);
} catch (SocketTimeoutException e) {
// 处理超时异常
// 可以进行重试、记录日志等操作
throw e;
}
}
}
使用示例:
import org.apache.sshd.client.SshClient;
import org.apache.sshd.client.session.ClientSession;
import org.apache.sshd.client.subsystem.scp.ScpClient;
public class Main {
public static void main(String[] args) {
try (SshClient client = SshClient.setUpDefaultClient()) {
client.start();
try (ClientSession session = client.connect("username", "hostname", 22).verify().getSession()) {
session.addPasswordIdentity("password");
session.auth().verify();
try (ScpClient scpClient = session.createScpClient()) {
CustomChannelOutputStream outputStream = new CustomChannelOutputStream(scpClient.getSendChannel().getSocket());
scpClient.setOutputStream(outputStream);
// 进行文件传输操作
// ...
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
这样,通过自定义的CustomChannelOutputStream类,可以增加apache SSHD的scpClient的ChannelOutputStream的等待超时时间。
