[原创]使用java批量修改文件编码（ANSI-->UTF-8）

从网上下载的项目，有时候.java文件的编码是ANSI。导入到自己的MyEclipse后，查看项目源码的时候，总是乱码。

一个个.java去修改的话，既麻烦又不现实。所以写了下面这个工具类，进行批量转编码。

代码的原理仅仅就是遍历文件，然后使用流，对按照文件的原编码进行读取，用目的编码进行写操作。

直接上源码：

package test;

import java.io.BufferedReader;

import java.io.BufferedWriter;

import java.io.File;

import java.io.FileInputStream;

import java.io.FileOutputStream;

import java.io.IOException;

import java.io.InputStreamReader;

import java.io.OutputStreamWriter;

public class Main {

	// private String sDirectory = "D:/Workspaces/BeyondDiscuz/src/com";

	private String sDirectory = "D:\\Workspaces\\BeyondDiscuz\\src\\com";

	private String dDirectory = "D:\\Workspaces\\BeyondDiscuz\\src\\cn";

	public static void main(String[] args) {

		Main 吗 = new Main();

		try {

			吗.readerFile(吗.sDirectory);

		} catch (IOException e) {

			e.printStackTrace();

		}

	}

	public void readerFile(String filePath) throws IOException {

		if ("".equals(filePath) || null == filePath) {

			return;

		}

		File f = new File(filePath);

		if (f.isDirectory()) {

			String[] child = f.list();

			for (int i = 0; i < child.length; i++) {

				String path = f.getAbsolutePath() + File.separator;

				String newPath = path.replace(this.sDirectory, this.dDirectory);

				child[i] = path + child[i];

				File c = new File(child[i]);

				String newFile = child[i].replace(this.sDirectory, this.dDirectory);

				System.out.println("旧路径：" + path);

				System.out.println("新路径：" + newPath);

				File newP = new File(newPath);

				if (!newP.exists())

					newP.mkdir();

				if (c.isFile()) {

					System.out.println("旧文件：" + child[i]);

					System.out.println("新文件：" + newFile);

					// Charset US-ASCII ISO-8859-1 UTF-8 UTF-16BE UTF-16LE UTF-16

					BufferedReader r = new BufferedReader(new InputStreamReader(new FileInputStream(c), "GBK"));

					// BufferedReader r = new BufferedReader(new InputStreamReader(new FileInputStream(c)));

					File newF = new File(newFile);

					newF.createNewFile();

					// BufferedWriter w = new BufferedWriter(new

					// OutputStreamWriter(new FileOutputStream(newF), "UTF-8"));

					BufferedWriter w = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(newF)));

					// BufferedWriter w = new BufferedWriter(new FileWriter(newFile));

					String lineText = null;

					while ((lineText = r.readLine()) != null) {

						// String temp = new String(lineText.getBytes("ISO-8859-1"), "UTF-8");

						w.write(lineText);

						w.newLine();

					}

					w.close();

					r.close();

				} else {

					readerFile(child[i]);

				}

			}

		}

	}

}

上面自己的写代码只是基本思路，下面是更简洁的代码：

public static void main(String[] args) {

        try {

            String srcDirPath = "E:\\eclipseWorkspaceSandbase\\test";

            // 转为UTF-8编码格式源码路径

            String utf8DirPath = "E:\\eclipseWorkspaceSandbase\\test-8";

            // 获取所有java文件

            Collection<File> javaGbkFileCol = FileUtils.listFiles(new File(srcDirPath), new String[] { "java" }, true);

            for (File javaGbkFile : javaGbkFileCol) {

                System.out.println(javaGbkFile);

                // UTF8格式文件路径

                String utf8FilePath = utf8DirPath + javaGbkFile.getAbsolutePath().substring(srcDirPath.length());

                // 使用GBK读取数据，然后用UTF-8写入数据

                FileUtils.writeLines(new File(utf8FilePath), "UTF-8", FileUtils.readLines(javaGbkFile, "GBK"));

            }

        } catch (Exception e) {

            e.printStackTrace();

        }

    }
