Java調用cmd命令，并輸出顯示信息:

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();

}

}

}

Java啟動本機應用程序EXE的三種方式:

第一種方式：利用cmd方式

/**

* 執行cmd命令

*

* @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");

第二種方式：利用ProcessBuilder調用cmd方式

/**

* 啟動應用程序

*

* @param programName

* @return

* @throws IOException

*/

public static void startProgram(String programPath) throws IOException {

log.info("啟動應用程序：" + programPath);

if (StringUtils.isNotBlank(programPath)) {

try {

String programName = programPath.substring(programPath.lastIndexOf("/") + 1, programPath.lastIndexOf("."));

List list = new ArrayList();

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("應用程序：" + programPath + "不存在！");

}

}

}

第三種方式：使用Desktop啟動應用程序

/**

* 啟動應用程序

*

* @param programName

* @return

* @throws IOException

*/

public static void startProgram(String programPath) throws IOException {

log.info("啟動應用程序：" + programPath);

if (StringUtils.isNotBlank(programPath)) {

try {

Desktop.getDesktop().open(new File(programPath));

} catch (Exception e) {

e.printStackTrace();

log.error("應用程序：" + programPath + "不存在！");

}

}

}
