需要ganymed-ssh2-build210.jar
1 連接
Connection conn = new Connection(ip地址, 端口號);
conn.connect();
2認證並判斷
boolean isAuthenticated = conn.authenticateWithPassword(用戶名, 密碼);
if (isAuthenticated == false){
System.out.println("密碼錯誤");
throw new IOException("Authentication failed.");
}
3打開一個Session
final Session session=conn.openSession();
4上傳文件（根據情況）
SCPClient client = new SCPClient(conn);
client.put(updateFileBytes, "xlsbz_server.zip", "/app/mhfx/");
5執行Shell命令（一般放線程里執行）
new Thread(new Runnable() {
public void run() {
try {
session.requestDumbPTY(); //建立虛擬終端
session.startShell(); //打開一個shell
OutputStream fout = session.getStdin(); //也可以用PrintWriter out = new PrintWriter(session.getStdin());
//輸入命令
fout.write(("bash xlsbz_server/bin/telnet.sh" + "\n").getBytes());
Thread.sleep(1000);
fout.write(("freeze" + "\n").getBytes());
Thread.sleep(60000);
fout.write(("quit" + "\n").getBytes());
Thread.sleep(1000);
fout.write(("bash xlsbz_server/bin/xlsbz.sh" + "\n").getBytes());
Thread.sleep(1000);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}).start();
6關閉session和相應流
session.close();
Thread.sleep(1000);
conn.close();
Thread.sleep(1000);
補充一點：
有時候需要從遠程服務器獲取返回結果
final InputStream is = new StreamGobbler(session.getStdout()); //StreamGobbler的作用是把session的標准輸出包裝成InputStream，用於接收目標服務器上的控制台返回結果，讀取br中的內容。然后在循環中，把每一行的內容添加到StringBuffer里面。
new Thread() {
public void run() {
BufferedReader br = new BufferedReader(new InputStreamReader(is));
while (true) {
try {
String line = br.readLine();
if (line == null) break;
System.out.println(line);
} catch (IOException e) {
e.printStackTrace();
}
}
try {
is.close();
br.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}.start();
