java 操作命令行

目的：用java进行调用ab压测

window： cmd ab.exe

linux： sh  ab.sh

命令： abs -n 500 -c 10 https://www.baidu.com/ > out.txt  简单直观可靠

那么用java如何调用ab进行压测呢

方法一

public static void methodOne() {
        String path;
        if (HostUtils.isWindows()) {
            path = "D:\\softInstall\\wamp2016_new\\bin\\apache\\apache2.4.9\\bin\\";
            String cmd = "cmd /C abs -n 300 -c 100 https://www.baidu.com/ >>abc.txt";
            String[] cmd2 = new String[]{"cmd", "/C", "abs", "-n", "300", "-c", "100", "https://www.baidu.com/", ">>abc.txt"};
            try {
                Process process = Runtime.getRuntime().exec(cmd2, null, new File(path));
                process.waitFor();
                InputStream inputStream = process.getInputStream();
                BufferedReader br = new BufferedReader(new InputStreamReader(inputStream, "gb2312"));
                String line = null;
                while ((line = br.readLine()) != null) {
                    System.out.println(line);
                }
            } catch (IOException e) {
                e.printStackTrace();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }

        }
    }

方法二

public static void methodTwo() {
        try {
            String result = new ProcessExecutor().command("cmd", "/C", "D:\\softInstall\\wamp2016_new\\bin\\apache\\apache2.4.9\\bin\\abs", "-n 300", "-c 100", "https://www.baidu.com/", ">>D:\\softInstall\\wamp2016_new\\bin\\apache\\apache2.4.9\\bin\\aa.txt")
                    .timeout(60, TimeUnit.SECONDS)
                    .readOutput(true).execute()
                    .outputUTF8();
            System.out.println(result);
        } catch (IOException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (TimeoutException e) {
            e.printStackTrace();
        }
    }

方法三

public static void methodThree() {
        try {
            Future<ProcessResult> cmd = new ProcessExecutor().command("cmd", "/C", "D:\\softInstall\\wamp2016_new\\bin\\apache\\apache2.4.9\\bin\\abs", "-n 300", "-c 100", "https://www.baidu.com/", ">>D:\\softInstall\\wamp2016_new\\bin\\apache\\apache2.4.9\\bin\\aa.txt")
                    .timeout(60, TimeUnit.SECONDS).readOutput(true).start().getFuture();
            String result = cmd.get().outputUTF8();
            System.out.println(result);
        } catch (IOException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (ExecutionException e) {
            e.printStackTrace();
        }
    }

压测对比：

性能都差不多，看个人爱好吧
