Question

我开发了一个Web应用程序（部署在weblogic服务器上），我想连接到solaris服务器并使用特定的unix用户执行shell脚本。目前，该脚本与wls用户一起运行。这是我的代码部分：

String CLA="-d";
out.println("Stopping ASAP for the changes to reflect ...");
                        ProcessBuilder processBuilder = new ProcessBuilder("/bin/ksh","/apps/vpn/asap/scripts/stop_asap_sys_tool"+" "+CLA);
                        process = processBuilder.start();
                        InputStream is = process.getInputStream();
                        InputStream isErr = process.getErrorStream();
                        InputStreamReader isr = new InputStreamReader(is);
                        InputStreamReader isrErr = new InputStreamReader(isErr);
                        BufferedReader br = new BufferedReader(isr);
                        BufferedReader brErr = new BufferedReader(isrErr);
                        String line;
                        String lineErr;

                        while ((line = br.readLine()) != null) {
                            System.out.println(line);
                        }
                        while ((lineErr = brErr.readLine()) != null) {
                            System.out.println(lineErr);
                        }

我的搜索结果建议使用Jsch。有人可以给我一个关于我使用Jsch的实现的例子。或者其他任何方式吗？！

谢谢， Bhavin

Answer 1

Jsch是一个很好的方式，这里可以帮助你做你想做的事情：

这里是StackOverflow [click]

建议，当您执行脚本，然后在Windows上编写或在那里打开它们时，您需要在文件上运行dos2unix（如果您在Linux上执行）;否则你的远程执行将会失败。

我认为这可以帮到你

public String execNixComAndGetRez(String user, String password, String host,
        String command) {

    int port = 22;
    String rez = "+!";

    try {
        JSch jsch = new JSch();
        Session session = jsch.getSession(user, host, port);
        session.setPassword(password);
        session.setConfig("StrictHostKeyChecking", "no");

        // System.out.println("Establishing Connection...");
        session.connect();

        ((ChannelExec) channel).setErrStream(System.err);

        InputStream in = channel.getInputStream();

        channel.connect();

        byte[] tmp = new byte[1024];

                rez = new String(tmp, 0, i);
            }
            if (channel.isClosed()) {
                // System.out.println("exit-status: "+channel.getExitStatus());

            }
        }
        channel.disconnect();
        session.disconnect();
    }

    catch (Exception e) {
        rez = e.toString();
    }
    return rez;
}

使用java（进程构建器）与特定的unix用户运行Shell脚本
