Windows系统中Java调用cmd命令及执行exe程序的方法
作者：qiaolevip
这篇文章主要介绍了Windows系统中Java调用cmd命令及执行exe程序的方法,主要用到了IOException类,需要的朋友可以参考下
Java调用cmd命令，并输出显示信息:
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启动本机应用程序EXE的三种方式:
第一种方式：利用cmd方式
/**
* 执行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");
第二种方式：利用ProcessBuilder调用cmd方式
/**
* 启动应用程序
*
* @param programName
* @return
* @throws IOException
*/
public static void startProgram(String programPath) throws IOException {
log.info("启动应用程序：" + 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("应用程序：" + programPath + "不存在！");
}
}
}
第三种方式：使用Desktop启动应用程序
/**
* 启动应用程序
*
* @param programName
* @return
* @throws IOException
*/
public static void startProgram(String programPath) throws IOException {
log.info("启动应用程序：" + programPath);
if (StringUtils.isNotBlank(programPath)) {
try {
Desktop.getDesktop().open(new File(programPath));
} catch (Exception e) {
e.printStackTrace();
log.error("应用程序：" + programPath + "不存在！");
}
}
}
