使用JAVA執行shell

引入依賴
1         <dependency>
            <groupId>ch.ethz.ganymed</groupId>
            <artifactId>ganymed-ssh2</artifactId>
            <version>262</version>
        </dependency>

創建Connection並連接
1 Connection conn = new Connection("IP");
conn.connect();

需要賬號密碼登錄的機器，進行校驗，返回布爾值
1 boolean login = conn.authenticateWithPassword(ACCOUNT, PASSWORD);

打開回話，並執行shell指令
1 Session session = conn.openSession();
session.execCommand("cd /home/scripts;ls");　　　　//多條指令時，用英文半角頓號隔開

getStdout()方法可拿到一個輸入流，即遠端控制台返回的數據

StreamGobbler gobbler = new StreamGobbler(session.getStdout());
BufferedReader reader = new BufferedReader(new InputStreamReader(gobbler));

　流處理
    StringBuilder result = new StringBuilder();
    while(true) {
        String readLine = reader.readLine();
        if (readLine == null) {
            reader.close();
            break;
        }
        result.append(readLine).append("\n\r");
    }    

 

 

getExitStatus()可獲取指令執行結果，0-成功；1-失敗

Integer exitStatus = session.getExitStatus();

切記：關閉reader、session、conn

 

 

 

 以下為完整可用的工具類
 1 　　　　 Connection conn = new Connection("IP");
        conn.connect();
        boolean login = conn.authenticateWithPassword("ACCOUNT", "PASSWORD");
        if (login) {
            Session session = conn.openSession();
            session.execCommand("cd /home/scripts;ls");
            StreamGobbler gobbler = new StreamGobbler(session.getStdout());
            BufferedReader reader = new BufferedReader(new InputStreamReader(gobbler));
            
            StringBuilder result = new StringBuilder();
            while(true) {
                String readLine = reader.readLine();
                if (readLine == null) {
                    reader.close();
                    break;
                }
                result.append(readLine).append("\n\r");
            }
            
            Integer exitStatus = session.getExitStatus();
            session.close();

            System.err.println("result:"+result);
            System.err.println("exit ? " + exitStatus);
        }
        
        if (conn != null) {
            conn.close();
        }
