java调用shell脚本

试了2种方法，一个是调用Runtime.getRuntime().exec(command)的方法来执行脚本，另一个是调用ProcessBuilder执行。相比前一个，ProcessBuilder支持多参数传入，而前一个只能用空格区分命令与参数，会将整个字符串作为shell来执行，而且在我测试过程中发现前一个无法读取shell写入到缓冲区的数据，因而在实际应用中选择了ProcessBuilder，测试代码如下：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

/**

public class ProcessBuilderShell {

    private void callShell(String cmd, String param1, String param2) {
        ProcessBuilder processBuilder = new ProcessBuilder(cmd, param1, param2);
        int runningStatus = 0;
        String s = null;
        try {
            Process p = processBuilder.start();
            BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
            BufferedReader stdError = new BufferedReader(new InputStreamReader(p.getErrorStream()));
            while ((s = stdInput.readLine()) != null) {
                System.err.println(s);
            }
            while ((s = stdError.readLine()) != null) {
                System.err.println(s);
            }
            try {
                runningStatus = p.waitFor();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }

        } catch (IOException e) {
            e.printStackTrace();
        }
        if (runningStatus != 0) {
            System.out.println("执行失败，code:"+runningStatus);
        }
    }

    public static void main(String[] args) {
        new ProcessBuilderShell().callShell("/oneapm/local/test_httpclient_bind_ip/cptSetIp.sh"
                ,args[0],args[1]);
    }
}
