I18n属性文件批处理

      在做国际化的时候，要不停的对表现层的标签和用户提示信息进行转码。大家一般都会使用JDK自动native2Ascii进行处理。为了简化开发人员对windows DOS下的操作，整理一个开发人员熟悉的JAVA文件进行处理。共享一下代码：

   

 I18NClass 是文件处理类： 

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;

public class I18NClass {

 /**操作系统的字符级*/
 private static String forwardEncoding = "UTF-8";//
 private static String reverseEncoding = "UTF-8";

 /**
  * 正向转化文件为ASCII字节码文件
  *
  * @param src
  * @param dest
  */
 public void forward(String srcFile, String destFile) {

  Runtime rn = Runtime.getRuntime();
  FileOutputStream fos = null;
  
  String srcPath = FilePathSymbol(srcFile);
  String destPath = FilePathSymbol(destFile);
  
  if (srcPath.length() > 0 && destPath.length() > 0) {
   try {
    String command = "native2ascii -encoding " + forwardEncoding +" "
      + srcPath;

    Process process = rn.exec(command);
    InputStream is = process.getInputStream();
    byte[] buf = new byte[1024];
    int bytesRead;
    //目标文件是否存在
    if(destPath.length()>0){
     int post = destPath.lastIndexOf(File.separator);
     String path = destPath.substring(0, post);
     File file = new File(path);
     if(!file.exists()){
      file.mkdirs();
     }
     
    }
    fos = new FileOutputStream(new File(destFile));
    while ((bytesRead = is.read(buf)) != -1) {
     fos.write(buf, 0, bytesRead);
    }
    fos.flush();
    fos.close();
   } catch (IOException e) {
    e.printStackTrace();
    if (fos != null) {
     try {
      fos.close();
     } catch (IOException e1) {
      e1.printStackTrace();
     }
    }
   }
  } else {
   System.out.println("核实文件是否都写有路径!");
  }
 }

 /**
  * 反向转化文件为源码文件
  *
  * @param dest
  * @param src
  */
 public void reverse(String srcFile, String destFile) {
  Runtime rn = Runtime.getRuntime();

  String srcPath = FilePathSymbol(srcFile);
  String destPath = FilePathSymbol(destFile);
  FileOutputStream fos = null;
  if (srcPath.length() > 0 && destPath.length() > 0) {
   try {
    String command = " native2ascii -reverse -encoding "
      + reverseEncoding +" "+ srcPath;
    System.out.println(command);
    Process process = rn.exec(command);
    InputStream is = process.getInputStream();
    byte[] buf = new byte[1024];
    int bytesRead;
    fos = new FileOutputStream(new File(destFile));
    while ((bytesRead = is.read(buf)) != -1) {
     fos.write(buf, 0, bytesRead);
    }
    fos.flush();
    fos.close();
   } catch (IOException e) {
    if (fos != null) {
     try {
      fos.close();
     } catch (IOException e1) {
      e1.printStackTrace();
     }
    }
   }
  } else {
   System.out.println("核实文件是否都写有路径!");
  }
 }

 /**
  * 判断文件是否存在
  *
  * @param filePath
  * @return
  */
 private String FilePathSymbol(String filePath) {

  if (null != filePath && !"".equals(filePath)) {
   if (filePath.indexOf("/") != -1) {
    return filePath.replace("/", File.separator);
   }
  } else {
   System.out.println("【" + filePath + "】不存在源文件!");

  }
  return "";
 }

 public static String getForwardEncoding() {
  return forwardEncoding;
 }

 public static void setForwardEncoding(String forwardEncoding) {
  I18NClass.forwardEncoding = forwardEncoding;
 }

 public static String getReverseEncoding() {
  return reverseEncoding;
 }

 public static void setReverseEncoding(String reverseEncoding) {
