尝试使用sudo -S -p.
我使用JSch位于的类的其他方式jsch-0.1.38.jar。
这个想法是将sudo输入从控制台重定向到java代码。
SudoExec 类
public abstract class SudoExec {
private String mHost;
private static String passwd;
private SSHObserverItf mObserver = null;
protected boolean isForceStop = false;
protected boolean isAsIs = false;
protected Timer mTimer = null;
//default constructor
public SudoExec(String hostName,String userName,String password){
setHost(userName+"@"+hostName);
setPassword(password);
}
public void init(int timeToWait) {
mTimer = new Timer();
new Thread(){
public void run(){
execCMD();
}
}.start();
mTimer.doWait(timeToWait);
isForceStop = true;
}
private void execCMD (){
isForceStop = false;
try{
JSch jsch=new JSch();
String host=getHost();
String user=host.substring(0, host.indexOf('@'));
host=host.substring(host.indexOf('@')+1);
Session session=jsch.getSession(user, host, 22);
// username and password will be given via UserInfo interface.
UserInfo ui=new MyUserInfo();
session.setUserInfo(ui);
session.connect();
String command=getCmd();
Channel channel=session.openChannel("exec");
((ChannelExec)channel).setPty(true);
if(isAsIs == true){
((ChannelExec)channel).setCommand(command);
}
else{
((ChannelExec)channel).setCommand("sudo -S -p '' " + command);
}
InputStream in=channel.getInputStream();
OutputStream out=channel.getOutputStream();
((ChannelExec)channel).setErrStream(System.err);
channel.connect();
out.write((passwd+"\n").getBytes());
out.flush();
byte[] tmp=new byte[1024];
while(true && isForceStop == false){
while(in.available()>0 ){
int i=in.read(tmp, 0, 1024);
if(i<0)break;
mObserver.onResponse((new String(tmp, 0, i)));
}
if(channel.isClosed()){
mObserver.onResponse("exit-status: "+channel.getExitStatus());
mTimer.doNotify();
break;
}
try{Thread.sleep(100);}catch(Exception ee){}
}
mObserver.onResponse("close channel ... ");
channel.disconnect();
mObserver.onResponse("close session ... ");
session.disconnect();
}
catch(Exception e){
System.out.println(e);
mObserver.onErrorResponse(e.getMessage());
}
}
public static class MyUserInfo implements UserInfo, UIKeyboardInteractive{
public String getPassword(){
return passwd;
}
public boolean promptYesNo(String str){
return true;
}
public String getPassphrase(){ return null; }
public boolean promptPassphrase(String message){ return true; }
public boolean promptPassword(String message){
return true;
}
public void showMessage(String message){
}
@Override
public String[] promptKeyboardInteractive(String arg0, String arg1,
String arg2, String[] arg3, boolean[] arg4) {
return null;
}
}
public void setPassword(String password){
passwd=password;
}
public void setHost(String hostname){
mHost=hostname;
}
public String getPassword(){
return passwd;
}
public String getHost(){
return mHost;
}
protected abstract String getCmd();
public void setObserver(SSHObserverItf observer) {
mObserver = observer;
}
}
SSHObserverItf 接口
public interface SSHObserverItf {
public void onResponse(String line);
public void onErrorResponse(String line);
}
一些任务
public class SomeTask extends SudoExec implements SSHObserverItf{
private static String command = "";
private static String hostname = "";
private static String user = "";
private static String pass = "";
private static Boolean isError=false;
private static String wait = "300";
static public void main(String args[]) throws IOException, ParseException, NoSuchFieldException, SecurityException, IllegalArgumentException, IllegalAccessException {
new SomeTask(hostname,user,pass);
if (isError == true){
System.out.println("Test failed");
}
else{
System.out.println("\nSucceeded to invoke command : " + command);
}
}
public CopyPeriodMergeToExternal(String hostName, String userName, String password) throws IOException, ParseException {
super(hostName, userName, password);
SSHObserverItf observer = this;
super.setObserver(observer);
super.init(Integer.parseInt(wait) * 1000);
}
@Override
protected String getCmd() {
isAsIs = true;
command="rm -f somescript.sh";
System.out.println("Run followed command : " + command);
return command;
}
@Override
public void onResponse(String line) {
System.out.println(line);
}
@Override
public void onErrorResponse(String line) {
System.out.println(line);
System.out.println("Error has occured");
isError = true;
}
}
课堂的主要部分SudoExec是：
public static class MyUserInfo implements UserInfo, UIKeyboardInteractive{
public String getPassword(){ // <---
return passwd;
}
public boolean promptYesNo(String str){
return true; // <---
}
希望它能解决你的问题
