遍历统计代码条数

最近在做公司软著，涉及项目较多，需要进行代码的统计和汇总，临时写了个脚本。分享一下。

代码很简单，只是方便自己明年做软著继续使用。

 

package com.wishos.ruanzhu;

import java.io.*;

public class App {
    // 这里为了好修改，全部设置了全局变量。
    private static String path = "/Users/wishos/Workspace/project01";
    private static String ext = ".java";
    private static String export = "/Users/wishos/Workspace/project01.txt";

    public static void main(String[] args) {
        scanPath(new File(path));
    }

    public static void scanPath(File path) {
        File[] files = path.listFiles();
        if (null == files) {
            return;
        }
        for (File file : files) {
            if (file.isDirectory()) {
                scanPath(file);
            } else {
                if (!file.getName().endsWith(ext)) {
                    continue;
                }
                try (FileReader fileReader = new FileReader(file);
                     BufferedReader bufferedReader = new BufferedReader(fileReader);
                     FileWriter fileWriter = new FileWriter(export, true);
                     BufferedWriter bufferedWriter = new BufferedWriter(fileWriter)
                ) {
                    String line;
                    while ((line = bufferedReader.readLine()) != null) {
                        bufferedWriter.write(line);
                        bufferedWriter.write("\n");
                    }
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}
