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
     
       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();        }    }
