ftp下载数据出现乱码 一个txt文件
URL u3=new URL("ftp://user:password@111.111.111.11:11//vehicle.txt");
urlconn3=u3.openConnection();
in3 = urlconn3.getInputStream();
BufferedReader br3=new BufferedReader(new InputStreamReader(in3));
StringBuffer t3 = new StringBuffer();
while((line=br3.readLine())!=null){
rec=line.split("\t");
String tel=rec[0];
String hpzl=rec[1];
String hphm=rec[2];
String jf=rec[3];
String fsxx1=rec[4];
System.out.println(fsxx1);
String fsxx = new String(fsxx1.getBytes("GBK"), "ISO-8859-1");
// String address=rec[3];
System.out.println(tel+hpzl+hphm+jf+fsxx1);
} 乱码 ftp
------解决方案--------------------
用apache ftpclient吧，部分样例代码
