文件编码

import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;

import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;
public class FileOuttest {

public static String file2Str(String file){
  //将文件转化为字节数组字符串，并对其进行Base64编码处理
  InputStream in = null;
  byte[] data = null;
  //读取文件字节数组
  BASE64Encoder Base64 = new BASE64Encoder();
  try{
    in = new FileInputStream(file);        
    data = new byte[in.available()];
    in.read(data);
    in.close();
  } catch (IOException e) {
    e.printStackTrace();
  }
  System.out.println(Base64.encode(data).toString());
  return new String(Base64.encode(data));

}


//public static void main(String[] args) {
