java远程执行shell命令

1、连接服务器，执行shell的方法

package com.shishike.susie.utility;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.Properties;
import java.util.Vector;

import org.apache.log4j.Logger;

import com.jcraft.jsch.Channel;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.JSchException;
import com.jcraft.jsch.Session;
import com.jcraft.jsch.ChannelExec;
import com.shishike.susie.model.SSHUserInfo;



public class ExecuteShell {
	private String ipAddress;  
	  
    private String username;  
  
    private String password;  
  
    public static final int DEFAULT_SSH_PORT = 22;  //默认是22
  
    private Vector stdout;  
	
    private static Logger logger = Logger.getLogger(ExecuteShell.class);
	
    public ExecuteShell(final String ipAddress, final String username, final String password) {  
        this.ipAddress = ipAddress;  
        this.username = username;  
        this.password = password;  
        stdout = new Vector();  
    }  
  
    public int execute(final String command) {  
        int returnCode = 0;  
        JSch jsch = new JSch();  
        SSHUserInfo userInfo = new SSHUserInfo();  
  
        try {  
            // Create and connect session.  
            Session session = jsch.getSession(username, ipAddress, DEFAULT_SSH_PORT);  
            session.setPassword(password);  
            session.setUserInfo(userInfo);  
            session.setConfig("StrictHostKeyChecking", "no");//去掉连接确认的
            session.connect(30000);  
  
            // Create and connect channel.  
            Channel channel = session.openChannel("exec");  
            ((ChannelExec) channel).setCommand(command);  
  
            channel.setInputStream(null);  
            BufferedReader input = new BufferedReader(new InputStreamReader(channel  
                    .getInputStream()));  
  
            channel.connect();  
            System.out.println("The remote command is: " + command);  
  
            // Get the output of remote command.  
            String line;  
            while ((line = input.readLine()) != null) {  
                stdout.add(line);  
            }  
            input.close();  
  
            // Get the return code only after the channel is closed.  
            if (channel.isClosed()) {  
                returnCode = channel.getExitStatus();  
            }  
  
            // Disconnect the channel and session.  
            channel.disconnect();  
            session.disconnect();  
        } catch (JSchException e) {  
            // TODO Auto-generated catch block  
            e.printStackTrace();  
        } catch (Exception e) {  
            e.printStackTrace();  
        }  
        return returnCode;  
    }  
    
    public static boolean executeRemoteShell(String ip, String username, String passwd, String command) {
    	ExecuteShell sshExecutor = new ExecuteShell(ip, username, passwd);  
        int result = sshExecutor.execute(command);  
        Vector stdout = sshExecutor.getStandardOutput();  
        for (String str : stdout) {  
            System.out.println(str);
            logger.info(str);
        }
        if (result == 0)
        	return true;
        else 
        	return false;
    }
    public Vector getStandardOutput() {  
        return stdout;  
    }
}

2、调用方式

	@Override
	public boolean mkDir(String jenkinsUser,String jenkinsPass,String serverAddr,String moduleName) {
		// TODO Auto-generated method stub
		
		String warpath="/home/work/.jenkins/jobs"+"/"+moduleName;
	    String command = String.format("if [ ! -d %s ]; then mkdir %s;fi",warpath,warpath);//command格式要正确
	   Boolean res= ExecuteShell.executeRemoteShell(serverAddr,jenkinsUser,jenkinsPass,command);
			
		return res;
	}

3、使用的依赖项

    com.jcraft
    jsch
    0.1.51
