疯子解决eclipse 编码问题的小工具
eclipse 默认为中文编码为gbk，当用gbk环境写的代码，其物理文件的编码为gbk.即使用eclipse 改为utf-8其物理文件的编码仍不变，所以通过以下代码生成。
package com.sparrow.utils;import java.io.BufferedReader;import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.IOException;import java.io.InputStreamReader;import java.io.OutputStreamWriter;import com.sparrow.constant.COMMON;import com.sparrow.core.Log;public class ConvertEncoding {private static boolean isTest = true;private static String sourceEncoding = "gb2312";private static String descEncoding = "UTF-8";/** * @author zlz * * @time 2013-7-16上午10:26:40 * @param args */public static void main(String[] args) {BufferedReader bf = new BufferedReader(new InputStreamReader(System.in));String rootPath = null;String yn = null;System.out.println("请输入要转换的路径");try {rootPath = bf.readLine();} catch (IOException e) {}Convert(rootPath);System.out.println("请输入文件的当前编码,回车默认为gbk");try {String tempEncoding = bf.readLine();if (!"".equals(tempEncoding)) {sourceEncoding = bf.readLine();}} catch (IOException e) {}System.out.println("请输入目标文件编码，回车默认为utf-8");try {String tempEncoding = bf.readLine();if (!"".equals(tempEncoding)) {descEncoding = bf.readLine();}} catch (IOException e) {}System.out.println("立即生成吗？Y/N");try {yn = bf.readLine();} catch (IOException e) {}if (yn.toLowerCase().equals("y")) {isTest = false;Convert(rootPath);System.out.println("ending");}}public static void Convert(String path) {File file = new File(path);File[] files = file.listFiles();for (File f : files) {if (f.isDirectory() && !f.isHidden()) {Convert(f.getPath());} else {String fileName = f.getPath();String sourceText = readFileContent(fileName, sourceEncoding);if (fileName.endsWith(".java")) {if (isTest) {System.out.println(sourceText);} else {writeFile(fileName, sourceText, descEncoding);System.out.println(fileName + " is encoded");}}}}}/** * 以行为单位读取文件，常用于读面向行的格式化文件 */public static String readFileContent(String fileName, String charset) {if (StringUtil.isNullOrEmpty(charset)) {charset = "UTF-8";}File file = new File(fileName);BufferedReader reader = null;StringBuffer sb = new StringBuffer();try {reader = new BufferedReader(new InputStreamReader(new FileInputStream(file), charset));String tempString = null;while ((tempString = reader.readLine()) != null) {sb.append(tempString);sb.append(COMMON.ENTER_TEXT);}reader.close();} catch (IOException e) {Log.getInstance().error(e);} finally {if (reader != null) {try {reader.close();} catch (IOException e1) {}}}return sb.toString();}public static boolean writeFile(String filePath, String s, String charset) {OutputStreamWriter osw = null;try {osw = new OutputStreamWriter(new FileOutputStream(filePath),charset);osw.write(s, 0, s.length());osw.flush();return true;} catch (Exception e) {Log.getInstance().error(e);return false;} finally {if (osw != null) {try {osw.close();} catch (IOException e) {}}}}} 1 楼 loloku 18 小时前 对你的贡献表示支持，但是同时我有个疑问，为什么不在一开始的时候就把GBK调成UTF-8？ 2 楼 zh_harry 18 小时前 这个工具是为编码不统一的情况开发的，如果编码统一的话就不用转码了，一开始调成UTF-8是标准的流程，但有些老项目或其他公司的项目会遇到这种情况，还有有些人没有在一开始配成UTF-8,以后再改真的很麻烦，这也是eclipse的不足吧，它应该支持！
