java代码远程执行shell脚本

1、脚本信息如下：

2、代码如下：

public class SSHTool {

    private Connection conn;
    private String ipAddr;
    private Charset charset = StandardCharsets.UTF_8;
    private String userName;
    private String password;

    public SSHTool(String ipAddr, String userName, String password, Charset charset) {
        this.ipAddr = ipAddr;
        this.userName = userName;
        this.password = password;
        if (charset != null) {
            this.charset = charset;
        }
    }

    /**
     * 登录远程Linux主机
     *
     * @return 是否登录成功
     */
    private boolean login() {
        conn = new Connection(ipAddr);
        try {
            // 连接
            conn.connect();
            // 认证
            return conn.authenticateWithPassword(userName, password);
        } catch (IOException e) {
            e.printStackTrace();
            return false;
        }
    }


    /**

     *
     * @param cmds 命令行序列
     * @return 脚本输出结果
     */

        InputStream in = null;
        StringBuilder result = new StringBuilder();
        try {

                // 打开一个会话
                Session session = conn.openSession();
                session.execCommand(cmds);
                in = session.getStdout();
                result = this.processStdout(in, this.charset);
                conn.close();

    }

        StringBuilder sb = new StringBuilder();
        try {
            // 此方法是休息10秒后最后一次性输出2行数据
            int length;
            while ((length = in.read(buf)) != -1) {
                sb.append(new String(buf, 0, length));
            }
