Java使用字符流拷贝文件出现乱码

//      BufferedWriter out = null;

Reader in = null;

Writer out = null;

try {

//          in = new BufferedReader(new FileReader(src));

//          in = new BufferedReader(new InputStreamReader(new FileInputStream(src)));

//          out = new BufferedWriter(new FileWriter(new File(dir, src.getName())));

//          out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(new File(dir, src.getName()))));

in = new FileReader(src);

out = new FileWriter(new File(dir, src.getName()));

System.out.println("正在拷贝文件(" + src + ")到目录("+dir+")下");

char[] buffer = new char[1024];

int len = 0;

while((len = in.read(buffer)) != -1) {

out.write(buffer, 0, len);

out.flush();

}

return true;

} catch (Exception e) {

return false;

} finally {

closeIO(in, out);

}
