jsch并运行“命令苏 - ”

Question

使用jsch

当我运行下面的CMD“须藤苏 - ”程序挂起

[TestNG] Running: 
C:\Users\brian.crosby\AppData\Local\Temp\testng-eclipse-952620154\testng-customsuite.xml 
[root@tbx2-toy-1 ~]# 

它看起来像“须藤苏 - ” becasue的工作输出状态“[root @ tbx2-toy-1〜]＃”，但是当我发送另一个cmd时，它没有响应。

继承人的代码：

package com.linux; 

import java.io.InputStream; 
import org.testng.annotations.*; 
import com.jcraft.jsch.*; 
import com.thoughtworks.selenium.*; 

public class LinuxConnection extends SeleneseTestBase{ 
String host = null; 
private StringBuilder strFileData; 
String randomFileName = null; 

public String getFileData() { 
    return strFileData.toString(); 
} 
public String getRandomFileName() { 
    return randomFileName; 
} 

public LinuxConnection() { 
    strFileData = new StringBuilder(); 
} 

@Test 
public void createUpdateTBX2FileData(String command)throws Exception { 

    try { 
     JSch jsch = new JSch(); 
     host = "brian-crosby@************.net"; 

     String user = host.substring(0, host.indexOf('@')); 
     host = host.substring(host.indexOf('@') + 1); 

     Session session = jsch.getSession(user, host, 22); 

     UserInfo ui = new MyUserInfo(); 
     session.setUserInfo(ui); 
     session.connect(); 

     ChannelExec channel = (ChannelExec)session.openChannel("exec"); 
     ((ChannelExec)channel).setPty(true); 
     ((ChannelExec) channel).setCommand(command); 

     ((ChannelExec) channel).setErrStream(System.err); 

     InputStream in = channel.getInputStream(); 
     channel.connect(); 

     byte[] tmp = new byte[2048]; 

     while (in.read(tmp, 0, 2048) > 0) { 
      String str = new String(tmp); 
      strFileData.append(str); 
      System.out.println(strFileData); 
     } 
     in.close(); 
     channel.disconnect(); 
     session.disconnect(); 
    } catch (Exception e) { 
     System.out.println(e); 
    } 
} 

public static class MyUserInfo implements UserInfo { 

    public String getPassword() { 
     return "********"; 
    } 

    public boolean promptYesNo(String str) { 
     str = "Yes"; 
     return true; 
    } 

    String passwd; 

    public String getPassphrase() { 
     return null; 
    } 

    public boolean promptPassphrase(String message) { 
     return true; 
    } 

    public boolean promptPassword(String message) { 
     passwd = "*******"; 
     return true; 
    } 

    public void showMessage(String message) { 

    } 
} 

} 

这里是我发送的CMDS：在谷歌

package com.linux; 

import org.testng.annotations.*; 

public class testLinuxConnection { 

@Test 
public void testLinux() throws Exception{ 
    LinuxConnection obj = new LinuxConnection(); 
    String command = "touch tester1.txt; sudo su -; rm tester1.txt;"; 
    obj.createUpdateTBX2FileData(command); 
} 
} 

我又花了几个小时试图找到一个解决方案，但没有成功

任何帮助表示赞赏

你是代码缺少剩下的代码需要为此运行。您需要从初始化的会话对象中初始化您需要的通道类型。既然你需要能够在彼此之后运行多个命令，你需要一个Shell类型通道：

您应该检查JSch的例子（即Shell.java），这里是一个快速参考：

/* -*-mode:java; c-basic-offset:2; indent-tabs-mode:nil -*- */ 
/** 
* This program enables you to connect to sshd server and get the shell prompt. 
* $ CLASSPATH=.:../build javac Shell.java 
* $ CLASSPATH=.:../build java Shell 
* You will be asked username, hostname and passwd. 
* If everything works fine, you will get the shell prompt. Output will 
* be ugly because of lacks of terminal-emulation, but you can issue commands.
