Java calls the cmd command and outputs the display information:
package com.anxin.cmd.test; import java.io.BufferedReader; import java.io.InputStreamReader; public class Command { public static void main(String[] args) { try { Runtime rt = Runtime.getRuntime(); Process pr = rt.exec("cmd /c dir"); // cmd /c calc // Process pr = rt.exec("D://xunlei//project.aspx"); BufferedReader input = new BufferedReader(new InputStreamReader(pr.getInputStream(), "GBK")); String line = null; while ((line = input.readLine()) != null) { System.out.println(line); } int exitVal = pr.waitFor(); System.out.println("Exited with error code " + exitVal); } catch (Exception e) { System.out.println(e.toString()); e.printStackTrace(); } } }There are three ways Java starts native application EXE:
The first method: use cmd method
/** * Execute the cmd command* * @param command * @throws IOException */ public static String executeCmd(String command) throws IOException { log.info("Execute command : " + command); Runtime runtime = Runtime.getRuntime(); Process process = runtime.exec("cmd /c " + command); BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream(), "UTF-8")); String line = null; StringBuilder build = new StringBuilder(); while ((line = br.readLine()) != null) { log.info(line); build.append(line); } return build.toString(); } executeCmd(start "AXAdWebBrowser" "D:/AXAdsBrowser/AXAdWebBrowser.exe"); The second method: use ProcessBuilder to call cmd method
/** * Start the application* * @param programName * @return * @throws IOException */ public static void startProgram(String programPath) throws IOException { log.info("Start the application: " + programPath); if (StringUtils.isNotBlank(programPath)) { try { String programName = programPath.substring(programPath.lastIndexOf("/") + 1, programPath.lastIndexOf(".")); List<String> list = new ArrayList<String>(); list.add("cmd.exe"); list.add("/c"); list.add("start"); list.add("/"" + programName + "/""); list.add("/"" + programPath + "/""); ProcessBuilder pBuilder = new ProcessBuilder(list); pBuilder.start(); } catch (Exception e) { e.printStackTrace(); log.error("Application:" + programPath + "Not exist!"); } } } The third way: use Desktop to start the application
/** * Start the application* * @param programName * @return * @throws IOException */ public static void startProgram(String programPath) throws IOException { log.info("Start the application: " + programPath); if (StringUtils.isNotBlank(programPath)) { try { Desktop.getDesktop().open(new File(programPath)); } catch (Exception e) { e.printStackTrace(); log.error("Application: " + programPath + "Not exist!"); } } }
