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 projectrepositories {    // 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' }
