我正在使用 java ssh 工具与我的学校帐户建立 ssh 连接并查找文件然后将其删除。但是,我正在创建三个函数来做同样的事情,但使用不同的文件,我正在寻找一种方法来做同样的事情,而不是一个接一个地做。这是一些代码。基本上我想知道是否有一种方法可以在一个 ssh 连接或某种分叉或多线程上完成这一切。
public void updateinterval() {
try {
JSch jsch = new JSch();
String user = "***********";
String host = "********";
Session session = jsch.getSession(user, host, 22);
session.setPassword("*********");
// username and password will be given via UserInfo interface.
UserInfo userInfo = new SftpUserInfo();
session.setUserInfo(userInfo);
session.connect();
// look for a file named feedinterval
String checkfortimeupdate =
"cd public_html/final;grep '-send' feedinterval";
Channel channel = session.openChannel("exec");
((ChannelExec) channel).setCommand(checkfortimeupdate);
// X Forwarding
// channel.setXForwarding(true);
// channel.setInputStream(System.in);
channel.setInputStream(null);
// channel.setOutputStream(System.out);
// FileOutputStream fos=new FileOutputStream("/tmp/stderr");
// ((ChannelExec)channel).setErrStream(fos);
((ChannelExec) channel).setErrStream(System.err);
InputStream in = channel.getInputStream();
channel.connect();
byte[] tmp = new byte[1024];
while (true) {
while (in.available() > 0) {
int i = in.read(tmp, 0, 1024);
if (i < 0)
break;
String returned = new String(tmp, 0, i);
String argument = returned.substring(6);
if (returned.contains("-send")) {
// if its there its calls the removeinterval function
// which removes the file it found
// by doing the same thing this function does but with a
// different ssh command
arduinoupdate hey = new arduinoupdate();
hey.removeinterval();
try {
Runtime rt = Runtime.getRuntime();
String[] commands = {
"system.exe", "-send", argument };
Process proc = rt.exec(commands);
}
catch (IOException e) {
}
}
}
if (channel.isClosed()) {
System.out.println("UpdateInterval Closed exit-status: "
+ channel.getExitStatus());
break;
}
try {
/* Thread.sleep(1000); */
} catch (Exception ee) {
}
}
channel.disconnect();
session.disconnect();
} catch (Exception e) {
System.out.println(e);
}
}
