Java Connection SSH Call Shell

First write a test script test.sh on the remote server and give the executable permission: chmod +x test.sh

#!/bin/bash echo ' test22 ' echo $

$ $ is the first parameter passed in the script, and our console prints this parameter

To create a new MAVEN project, add dependencies:

<dependency> <groupId>org.jvnet.hudson</groupId> <artifactid>ganymed-ssh2</artifactid > <version>build210-hudson-1</version> </dependency>

Write a tool class:

import java.io.ioexception;  import java.io.inputstream;  import  java.nio.charset.charset;    import ch.ethz.ssh2.connection;  import  ch.ethz.ssh2.session;    public class remoteshelltool {         private connection conn;      private  String ipAddr;      private String charset =  Charset.defaultcharset (). toString ();      private string username;       private String password;         public remoteshelltool (string ipaddr, string username, string  password,              string  CharSet)  {          this.ipaddr = ipaddr;           this.userName = userName;           this.password = password;          if  ( Charset != null)  {               this.charset = charset;          }       }        public boolean  Login ()  throws ioexception {          conn  = new connection (IPADDR);           Conn.connect (); //  connection           return  Conn.authenticatewithpassword (Username, password); //  Certification       }        public  string exec (STRING CMDS)  {           inputstream in = null;          string  result =  "";          try {               if  (This.login ())  {                   Session  Session = conn.opensession (); //  Open a session                    session.execcommand (CMDS);                                       in = session.getstdout ();                   result =  this.processstdout (In, this.charset);                   session.close ();                   conn.close ();               }           } catch  (IOEXCEPTION E1)  {               e1.printstacktrace ();           }          return result;       }         public string processstdout (inputstream in, string  CharSet)  {                 byte[] buf = new byte[1024];           stringbuffer sb = new stringbuffer ();           try {               while  (In.read (BUF)  != -1)  {                   sb.append (new string (buf, charset));               }           } catch  (ioexception e)  {                e.printstacktrace ();          }           return sb.tostring ();       }        /**      *  @param   Args      */      public static void  main (String[] args)  {             Remoteshelltool tool = new remoteshelltool ("192.168.27.41",  "Hadoop",                    "Hadoop",   "Utf-8");             string result  = tool.exec ("./test.sh xiaojun");           System.out.print (Result);        }    } 

The main function executes the./test.sh Xiaojun This command, the console prints out:

test22

Xiaojun
