私はMina SSHDサーバー（0.14.0）とCamel SSHコンポーネント（2.16.2）でSSHD統合デモを作成しようとしています。今はパテでSSHDと完全に通信できますが、SSHDとCamelを統合できないため、Camel ProducerTemplateのrequestBody（）から何の応答も得られませんでした。デバッグの一日の後、まだ動作しません。ここ は私のSSHDコードです：次のようにCamel ProducerTemplateのrequestBody（）がスタックしました
public class EchoSshServer {
public void startSshServer() throws IOException {
SshServer sshd = SshServer.setUpDefaultServer();
sshd.setPort(22);
sshd.setKeyPairProvider(new SimpleGeneratorHostKeyProvider("d:\\hostkey.ser"));
sshd.setPasswordAuthenticator(new PasswordAuthenticator() {
@Override
public boolean authenticate(String u, String p, ServerSession s) {
if ("sync".equals(u) && "sync".equals(p))
return true;
return false;
}
});
//sshd.setShellFactory(new EchoShellFactory());
sshd.setCommandFactory(new EchoCommandFactory());
sshd.start();
}
public static void main(String[] args) {
try {
new EchoSshServer().startSshServer();
Thread.sleep(Integer.MAX_VALUE);
} catch (InterruptedException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
コマンド・ファクトリー・コードは次のとおりです。
public class EchoCommandFactory implements CommandFactory {
@Override
public Command createCommand(String command) {
return new EchoCommand(command);
}
public static class EchoCommand implements Command, Runnable {
private String request;
public EchoCommand(String request) {
this.request = request;
}
private InputStream in;
private OutputStream out;
private OutputStream err;
private ExitCallback callback;
private Environment environment;
private Thread thread;
@Override
public void start(Environment env) throws IOException {
environment = env;
thread = new Thread(this, "EchoCommand");
thread.start();
}
@Override
public void run() {
System.out.print(request);
try {
out.write((request).getBytes(StandardCharsets.UTF_8));
out.flush();
} catch (IOException e) {
e.printStackTrace();
}
}
@Override
public void setInputStream(InputStream in) {
this.in = in;
}
@Override
public void setOutputStream(OutputStream out) {
this.out = out;
}
@Override
public void setErrorStream(OutputStream err) {
this.err = err;
}
@Override
public void setExitCallback(ExitCallback callback) {
this.callback = callback;
}
@Override
public void destroy() {
thread.interrupt();
}
}
}
とクライアント側のコード：
public static void main(String[] args) throws Exception {
CamelContext context = new DefaultCamelContext();
context.addRoutes(new RouteBuilder() {
@Override
public void configure() throws Exception {
from("direct:start").to("ssh://sync:[email protected]:22");
}
});
context.start();
ProducerTemplate template = context.createProducerTemplate();
String reply = template.requestBody("direct:start", "login:bot", String.class);
System.out.println(reply);
}
クライアントがrequestBodyにはまります（）メソッドでは、サーバーのログは次のようになります。
