使用jsch
当我运行以下cmd'sudo su - '程序挂起时
[TestNG] Running:
C:\Users\brian.crosby\AppData\Local\Temp\testng-eclipse-952620154\testng-customsuite.xml
[root@tbx2-toy-1 ~]#
它看起来像“sudo su - ”，因为输出状态“[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) {
}
}
}
这是我发送cmds的地方：
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);
}
}
我再次花了几个小时在谷歌试图找到一个解决方案，但没有成功

您的代码缺少运行所需的其余代码。您需要从初始化的会话对象中初始化所需的通道类型。由于您需要能够在彼此之后运行多个命令，因此您需要一个Shell类型的通道：
你应该查看JSch的例子（即Shell.java），这里有一个快速参考：
/* -*-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.
*
