JSch是SSH2的纯Java实现 。
JSch允许您连接到sshd服务器并使用端口转发,X11转发,文件传输等,您可以将其功能集成到您自己的Java程序中。JSch获得BSD格式许可证。
最初,我们开发这些东西的动机是允许我们的纯Java X服务器 WiredX的用户享受安全的X会话。所以,我们的努力主要是为了实现用于X11转发的SSH2协议。当然,我们现在也有兴趣添加端口转发,文件传输,终端仿真等其他功能。
官网上有很详细说明和例子:

1. 工具类:
package util;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.concurrent.TimeUnit;
import com.jcraft.jsch.Channel;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;
public class SSHUtil {
private Channel channel;
private Session session = null;
private int timeout = 60000;
public SSHUtil(final String ipAddress, final String username, final String password) throws Exception {
JSch jsch = new JSch();
this.session = jsch.getSession(username, ipAddress, 22);
this.session.setPassword(password);
this.session.setConfig("StrictHostKeyChecking", "no");
this.session.setTimeout(this.timeout);
this.session.connect();
this.channel = this.session.openChannel("shell");
this.channel.connect(1000);
}
public String runShell(String cmd, String charset) throws Exception {
String temp = null;
InputStream instream = null;
OutputStream outstream = null;
try {
instream = this.channel.getInputStream();
outstream = this.channel.getOutputStream();
outstream.write(cmd.getBytes());
outstream.flush();
TimeUnit.SECONDS.sleep(2);
if (instream.available() > 0) {
byte[] data = new byte[instream.available()];
int nLen = instream.read(data);
if (nLen < 0) {
throw new Exception("network error...桌面有错误");
}
temp = new String(data, 0, nLen, "UTF-8");
}
} finally {
outstream.close();
instream.close();
}
return temp;
}
public void close() {
this.channel.disconnect();
this.session.disconnect();
}
}
2. 调用:
import util.SSHUtil;
public class Test {
public static void main(String[] args) throws Exception{
SSHUtil sshUtil = new SSHUtil("xx.xx.xx.2", "root", "xxxxxng");
String res = sshUtil.runShell("cd xxx\n ps -ef | grep java | awk '{print $2}' | xargs kill -9 \n nohup java -jar xxxx-0.0.1-SNAPSHOT.jar & \n", "utf-8");
//重启数据库
//String res = sshUtil.runShell("docken restart JY_mysql \n", "utf-8");
//String res = sshUtil.runShell("nohup java -jar forlovehome-0.0.1-SNAPSHOT.jar & \n", "utf-8");
// String res = sshUtil.runShell("/usr/apache-tomcat-7.0.47/bin/startup.sh\n", "utf-8");
System.out.println(res);
sshUtil.close();
}
}
