我正在尝试使用Jsch编写Java程序,在该程序中,我想使用该程序开始执行Shell脚本,并在执行完Shell脚本后退出该程序.

String userName = "";

String hostName = "";

String password = "";

JSch javaSecureChannel = new JSch();

Session jschSession = null;

Channel jschChannel = null;

try {

jschSession = javaSecureChannel.getSession(userName, hostName, 22);

Properties configurationProperties = new Properties();

configurationProperties.put("StrictHostKeyChecking", "no");

jschSession.setConfig(configurationProperties);

jschSession.setPassword(password);

jschSession.connect();

jschChannel = null;

jschChannel = jschSession.openChannel("shell");

jschChannel.setOutputStream(System.out);

File shellScript = createShellScript();

FileInputStream fin = new FileInputStream(shellScript);

byte fileContent[] = new byte[(int) shellScript.length()];

fin.read(fileContent);

InputStream in = new ByteArrayInputStream(fileContent);

jschChannel.setInputStream(in);

jschChannel.connect();

while(true){

//if(jschChannel.isClosed)

if(jschChannel.getExitStatus() == 0){

System.out.println("exit-status: " + jschChannel.getExitStatus());

break;

}

try{

Thread.sleep(1000);

}catch(Exception ee){

ee.printStackTrace();

}

}

} catch (Exception e) {

e.printStackTrace();

}

jschChannel.disconnect();

jschSession.disconnect();

System.out.println("Done...!!!");

createShellScript方法如下.

String temporaryShellFileName = "shellscript.sh";

File fileStream = new File(temporaryShellFileName);

try {

PrintStream outStream = new PrintStream(new FileOutputStream(fileStream));

outStream.println("#!/bin/bash");

outStream.println("cd /u01/app/java/gids4x/Test");

outStream.println("Test_with_NULL.sh");

outStream.close();

} catch (Exception e) {

System.err.println("Error: " + e.getMessage());

}

使用上面的代码,我可以开始执行Shell脚本.但是,即使在程序执行完成之后,即在脚本执行完成之后,我也不会终止程序执行.

您能否建议需要准确执行的操作？
