用Java程序代替Notepad++的文字处理和Powershell

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<String> aLink = new ArrayList<String>();        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...");    }}
