Java 将批量的gbk的乱码文件转换到utf8

由于自己的eclipse设置时UTF8，导入别人写的代码，全是乱码。

在eclipse下又发现不了gbk，于是写了个工具转换。

不支持目录迭代。

package com.iteye.niewj.util;
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 java.io.PrintWriter;


public class UTF8Parser {


static File srcDir = new File("D:/prj/java/niewj_oy/eclipse_swt_src/src/swt/");
static File destDir= new File("D:/prj/java/niewj_oy/eclipse_swt_src/src/swt_cp/");

public static void main(String[] args) {
//1.判断是目录
if(!srcDir.isDirectory()){
return;
}
//2.遍历所有目录
File[] fs = srcDir.listFiles();

//创建目标目录
if(!destDir.exists()){
destDir.mkdirs();
}

try {
new UTF8Parser().parse(fs);
} catch (IOException e) {
e.printStackTrace();
}
}


private void parse(File[] fs) throws IOException {
for(File file:fs){
if(!file.isDirectory()){
File destFile = new File(destDir,file.getName());
parse2UTF_8(file,destFile);
}else{
parse(file.listFiles());
}
}
}


private void parse2UTF_8(File file,File destFile) throws IOException {
StringBuffer msg = new StringBuffer();
//读写对象
PrintWriter ps = new PrintWriter(new OutputStreamWriter(new FileOutputStream(destFile,false),"utf8"));
BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(file),"gbk"));

//读写动作
String line = br.readLine();
while(line!=null){
msg.append(line).append("rn");
line = br.readLine();
}
ps.write(msg.toString());
br.close();
ps.flush();
ps.close();
}

}
