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'

}
