SSH Apache Minaはファイルの内容を読み取って印刷します

Question

Hellooo私はサーバ用にapache minaを使用していますが、いくつかのコマンドを返すechoshellfactoryを作りたいと思います。

私はそれを作ったが、私はfr（）メソッドを印刷するコマンドが必要な場合、Eclipseコンソールでは出力するが、パテコンソールでは印刷しない。

私は、これは応答がStringであることを知っていますが、レスポンスを全体の方法にするための方法があります。

public class EchoShellFactory implements Factory<Command> { 

public Command create() { 
    return new EchoShell(); 
} 

public static class EchoShell implements Command, Runnable { 

    private static final String SHELL_THREAD_NAME = "name"; 
    private static final String SHELL_PROMPT = "aaa# ====> "; 
    private static final String SHELL_CMD_QUIT = "quit"; 
    private static final String SHELL_CMD_EXIT = "exit"; 
    private static final String SHELL_CMD_VERSION = "version"; 
    private static final String SHELL_CMD_HELP = "help"; 
    private static final String SHELL_CMD_FILEREADER = "fr"; 
    private static final String SHELL_CMD_ENTER = ""; 

    private InputStream in; 
    private OutputStream out; 
    private OutputStream err;

    public InputStream getIn() { 
     return in; 
    }

     return out; 
    } 

    public OutputStream getErr() { 
     return err; 
    }

     this.in = in; 
    } 

    public void setOutputStream(OutputStream out) { 
     this.out = out;

     thread.start();

      reader.addCompleter(new StringsCompleter(SHELL_CMD_QUIT, SHELL_CMD_EXIT, SHELL_CMD_VERSION, 
        SHELL_CMD_HELP, SHELL_CMD_FILEREADER)); 
      writer = new PrintWriter(reader.getOutput()); 

      // output welcome banner on ssh session startup 
      writer.println("****************************************************"); 
      writer.println("*    Welcome to aaa.     *"); 
      writer.println("****************************************************"); 
      writer.flush(); 

      String line; 
      while ((line = reader.readLine()) != null) { 
       handleUserInput(line.trim()); 
      } 

     } catch (InterruptedIOException e) { 
      // Ignore 
     } catch (Exception e) { 
      e.getLocalizedMessage(); 
     } finally { 
      callback.onExit(0); 
     } 
    } 

    private void handleUserInput(String line) throws InterruptedIOException, FileNotFoundException { 

     if (line.equalsIgnoreCase(SHELL_CMD_QUIT) || line.equalsIgnoreCase(SHELL_CMD_EXIT)) 
      throw new InterruptedIOException(); 

     String response = null; 

     if (line.equalsIgnoreCase(SHELL_CMD_VERSION)) 
      response = "Version 1.0.0"; 
     else if (line.equalsIgnoreCase(SHELL_CMD_FILEREADER)) 
      fr(); 
     else if (line.equalsIgnoreCase(SHELL_CMD_HELP)) 
      response = "Help is not implemented yet..."; 
     else if (line.equalsIgnoreCase(SHELL_CMD_ENTER)) 
      response = ""; 
     else 
      response = "======> \"" + line + "\" is unknown command"; 

     writer.println(response); 
     writer.flush(); 
    } 
} 
} 

Answer 1

fr（）メソッドは必要ありません。代わりに、印刷方法frの

（）は、次の操作を行います

response = new String(Files.readAllBytes(Paths.get("C:\\Users\\John\\Desktop\\asd.txt")));
