sshj 示例

开发常常需要去服务器做一些操作，比如配置一下，或者取服务器的配置什么的，需要写点工具方便开发。

下面是一个使用sshj 模拟ssh的过程。

package sshStuff;

import net.schmizz.sshj.SSHClient;
import net.schmizz.sshj.common.IOUtils;
import net.schmizz.sshj.connection.channel.direct.Session;
import net.schmizz.sshj.connection.channel.direct.Session.Command;
import net.schmizz.sshj.transport.verification.PromiscuousVerifier;

public class Functor {

	public static void main(String[] args) throws Exception {
		String TMP = "http://10.59.60.231:31154";
		if(args.length >= 1){
			TMP = args[0];
		}
		String ret = connect(TMP);
		System.out.println(ret);
	}

	public static String connect(String url) throws Exception {
		SSHClient ssh = new SSHClient();
		ssh.addHostKeyVerifier(new PromiscuousVerifier());
		ssh.connect(getIp(url), getPort(url));
		ssh.authPassword("root", "123456");

		Session session = ssh.startSession();
		Command cmd = session.exec("cat /usr/local/tomcat/StartTomcat.sh");
		String ret = IOUtils.readFully(cmd.getInputStream()).toString();
		// System.out.println(ret);
		session.close();
		ssh.close();
		return ret;
	}

	private static String getIpPort(String url) {

		String[] slash = url.split("/");
		String ipport = null;
		if (url.toLowerCase().startsWith("http")) {
			ipport = slash[2];
		} else {
			ipport = slash[0];
		}
		return ipport;
	}

	private static String getIp(String url) {
		String ipport = getIpPort(url);
		return ipport.split(":")[0];
	}

	private static int getPort(String url) {
		String ipport = getIpPort(url);
		return Integer.parseInt(ipport.split(":")[1]) + 1;
	}

}

下面是gradle配置

apply plugin: 'java'

repositories {
    mavenCentral()
}

dependencies {
   
    compile group: 'net.schmizz', name: 'sshj', version: '0.10.0'
}

// In this section you declare where to find the dependencies of your project
repositories {
    // Use jcenter for resolving your dependencies.
    // You can declare any Maven/Ivy/file repository here.
    jcenter()
}


jar {
	from {configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } } 
    manifest {
        attributes 'Main-Class': 'sshStuff.Functor'
    }
    exclude 'META-INF/*.RSA', 'META-INF/*.SF','META-INF/*.DSA' 
}
