linux下的java通过ftp读取另一linux下的文件名出现中文乱码。

public static void loadMyFile(String regStr,String ip,String usrname,String pwd,Integer m){
connectMyServer(ip,usrname,pwd);
try {
FtpClient.changeWorkingDirectory(regStr);
String files[] = FtpClient.listNames(regStr);
if (files == null || files.length == 0)
System.out.println("没有文件!");
else {
for (int i = 0; i < files.length; i++) {
System.out.println(files[i]); String filename=files[i].substring(regStr.length()+1,files[i].length());
System.out.println("文件名"+filename);
String remoteFileName=regStr+"/"+files[i];
BufferedOutputStream buffOut = null;
try {
buffOut = new BufferedOutputStream(new FileOutputStream("/doc"+files[i]));
FtpClient.retrieveFile(remoteFileName, buffOut);
} catch (Exception e) {
e.printStackTrace();
logger.debug("本地文件下载失败！", e);
} finally {
try {
if (buffOut != null)
buffOut.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
}finally{
closeConnect();
}

}

/**

public static boolean connectMyServer(String ip,String usrname,String pwd) {
boolean flag = true;
int reply;
try {

需要转一下编码，你的java的class文家中是GBK的编码，对面linux下是iso8859－1编码
String fileNameTmp = new String(files[i].getBytes("iso-8859-1"), "GBK");//将从linux取得的文件名转换为GBK编码
String filename=fileNameTmp .substring(regStr.length()+1,fileNameTmp .length());
然后再把转完编码的文件名按你的要求进行截取
