批处理学习以及批处理脚本案例
批处理脚本语法总结:
批处理脚本语法学习: @echo "Hello world" rem 类似于 System.out.println(); 输出语句 md D:\mybat //将在D盘下创建一个名为 mybat的文件夹 rd D:\mybat //将删除D盘中的mybat文件夹删除 del D:\mybat\sheepmu.txt //删除文件sheepmu.txt del D:\mybat\sheepmu.txt /q //安静模式删除,即删除时不弹出是否删除的提示框 xcopy D:\mybat\sheepmu.txt D:\mybat1 //若D中无mybat1这个文件夹则会创建文件夹再复制 e.向文件中写入内容: echo sheepmu >> D:\mybat\sheepmu.txt //如果这个文件不存在就创建文件并输入。如果是文件 夹不存在就不会成功! >>与>的区别是>是覆盖掉原来 的;>>是直接输入到原来的尾部 f.显示文件中内容: type D:\mybat\sheepmu.txt g.更改文件名后缀: ren D:\mybat\*.txt *.html
rem 自动安装字体文件到 windows 系统上 注: 字体文件与 bat 脚本文件在同一个目录下。如上图 @echo off setlocal EnableDelayedExpansion cd %~dp0 rem 相当于cd 到当前目录 for /f "delims=" %%i in ('dir /x /b *.?tf') do ( set "zt=%%~si" mshta "javascript:new ActiveXObject('Shell.Application').NameSpace(20).CopyHere('!zt:\=\\!',0x0010);close()" ) echo. echo 字体安装完毕! pause >nul
二:调用方式:
String batPath = "D:/文档/aa/aa.bat"; // 把你的bat脚本路径写在这里 Integer result= ExecuteShellUtils.execute(batPath); System.out.println(result);
三:java 执行 批处理或者shell 脚本的工具类:
package com.resafety.design.studio.controller; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import java.util.concurrent.Callable; import java.util.concurrent.Executors; import java.util.concurrent.Future; import java.util.concurrent.ScheduledExecutorService; import java.util.concurrent.TimeUnit; import com.resafety.util.LogUtils; /** * 执行脚本工具类 * @author 石 * */ public class ExecuteShellUtils { /** * 执行脚本 * @param shell * @return * @throws Exception */ public static Integer execute(String shell) throws Exception{ Runtime runtime = Runtime.getRuntime(); Process process = runtime.exec(shell); ProcessClearStream error=new ProcessClearStream(process.getErrorStream(), "Error"); ProcessClearStream output= new ProcessClearStream(process.getInputStream(),"OutPut"); error.start(); output.start(); Callable<Integer> call=new Callable<Integer>() { public Integer call() throws Exception { Integer status=process.waitFor(); return status; } }; ScheduledExecutorService singleThreadScheduledExecutor = Executors.newSingleThreadScheduledExecutor(); Future<Integer> submit = singleThreadScheduledExecutor.submit(call); //5分钟脚本未执行完成认为线程阻塞了,强制结束线程 Integer status = submit.get(5, TimeUnit.MINUTES); return status; } /** * 清空脚本缓存流类,防止线程阻塞 * @author 石 * */ static class ProcessClearStream extends Thread{ private InputStream inputStream; private String type; public ProcessClearStream(InputStream inputStream, String type) { this.inputStream = inputStream; this.type = type; } public void run() { try { InputStreamReader inputStreamReader = new InputStreamReader( inputStream,"GBK"); BufferedReader br = new BufferedReader(inputStreamReader); // 打印信息 String line = null; while ((line = br.readLine()) != null) { //LogUtils.debug(line); System.out.println(line); } // 不打印信息 // while (br.readLine() != null); } catch (IOException ioe) { ioe.printStackTrace(); } } } }
