如何使用Java程序代替Notepad++的文字处理和Powershell

这篇文章给大家分享的是有关如何使用Java程序代替Notepad++的文字处理和Powershell的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。

由于Notepad++里面的文字处理有些复杂，我在想能不能用一个Java程序来统一处理呢？

尝试了一下，发现不太复杂，Java果然处理各种事情都比较方便。程序如下：

注意在RegExp里面，必须用四个反斜杠\\\\代表一个反斜杠\

package com.pwc;import java.io.BufferedReader;import java.io.ByteArrayOutputStream;import java.io.DataInputStream;import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.IOException;import java.io.InputStreamReader;import java.net.URL;import java.util.ArrayList;import java.util.regex.Matcher;import java.util.regex.Pattern;public class WechatMomentDownload {        public static String jsonFile = "C:\\Download\\exported_sns_gary.json";    public static String outputFolder = "C:\\Download\\gary_pic\\";    public static void main(String[] args) throws IOException {        BufferedReader reader = null;        String sLine = "";        String sContent = "";        String sLink = "";        URL url = null;        String outputFile = "";        ArrayList aLink = new ArrayList();        String Regex1 = "CDATA\\[http\\:\\\\\\/\\\\\\/(sh)?mmsns([^]]*)\\/0\\]";                reader = new BufferedReader(                new InputStreamReader(new FileInputStream(new File(jsonFile)), "UTF-8"));        if (reader != null) {            while ((sLine = reader.readLine()) != null) {                sContent = sContent + sLine;            }            reader.close();        }                Pattern pattern = Pattern.compile(Regex1);        Matcher matcher = pattern.matcher(sContent);        int count = 0;                System.out.println("Start processing...");        while(matcher.find()) {            count++;            sLink = sContent.substring(matcher.start() + 6, matcher.end() - 1);            sLink = sLink.replaceAll("\\\\/", "/");            aLink.add(sLink);         }                System.out.println(count + " pictures were found");                for (String sLinkTemp : aLink) {            url = new URL(sLinkTemp);            DataInputStream dataInputStream = new DataInputStream(url.openStream());                        outputFile = outputFolder + count + ".jpg";            FileOutputStream fileOutputStream = new FileOutputStream(new File(outputFile));            ByteArrayOutputStream output = new ByteArrayOutputStream();            System.out.println("Downloading " + sLinkTemp + " to file " + outputFile);                        byte[] buffer = new byte[1024];            int length;             while ((length = dataInputStream.read(buffer)) > 0) {                output.write(buffer, 0, length);            }            fileOutputStream.write(output.toByteArray());            dataInputStream.close();            fileOutputStream.close();                    count--;        }                System.out.println("End of processing...");    }}
