Java _ Java 执行Linux 指令，

完整项目：http://pan.baidu.com/s/1eRUDslG

核心代码：

    Process process = Runtime.getRuntime().exec(cmd);
    InputStreamReader ir = new InputStreamReader(process.getInputStream());
    LineNumberReader input = new LineNumberReader(ir);

    String line;
    while ((line = input.readLine()) != null) {
        System.out.println(line);
    }

完整示例代码：（封装的共有方法）：

package test.szh.util;

import java.io.IOException;
import java.io.InputStreamReader;
import java.io.LineNumberReader;

public class RunCommand {

	public synchronized static String runCommands(String[] args)
			throws IOException, InterruptedException {

		String cmd = "";

		if (args == null || args.length == 0) {
			System.out.println("请输入命令行参数");
		} else {
			for (int i = 0; i < args.length; i++) {
				cmd += args[i] + " ";
			}
		}

		StringBuffer result = null;
		try {

			Process process = Runtime.getRuntime().exec(cmd);
			InputStreamReader ir = new InputStreamReader(
					process.getInputStream());
			LineNumberReader input = new LineNumberReader(ir);

			String line;
			result = new StringBuffer();

			while ((line = input.readLine()) != null) {
				result.append(line + "\n");
				System.out.println(line);

			}

		} catch (java.io.IOException e) {
			System.err.println("IOException " + e.getMessage());
		}

		return result.toString();

	}

	public static void main(String[] args) throws IOException,
			InterruptedException {
		String[] cmds = { "curl http://192.168.3.14:8078/kafka/detail -d topic=clicki_track_topic&consumer=clicki_track_storm_base" };
		System.out.println(runCommands(cmds));
	}

}
