import java.nio.file.attribute.BasicFileAttributes;</div>
<div>public class ChangeGBK2UTF {</div>
<div>/**

 * @throws IOException 
 */
public static void main(String[] args) throws IOException {
Path path = Paths.get("C:/src");
String pattern = "**/*.java";
final PathMatcher matcher = FileSystems.getDefault().getPathMatcher(
"glob:" + pattern);
SimpleFileVisitor<Path> visitor = new SimpleFileVisitor<Path>() {
@Override
public FileVisitResult visitFile(Path file,
BasicFileAttributes attrs) {
if (matcher.matches(file)) {
System.out.println("to process " + file);
try {
byte[] bytes = Files.readAllBytes(file);
String gbkContent = new String(bytes, "gb18030");</div>
<div>Files.write(file, gbkContent.getBytes("UTF-8"));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return FileVisitResult.CONTINUE;
}
};
Files.walkFileTree(path, visitor);
}
}
</div>

试试其它关键字
