java之base64code

最近在做项目中遇到base64code处理的问题。下面是我写的示例：

package com.juck.test;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;


public class Base64Code{

    //测试主方法
    public static void main(String[] args){

        final String fileName = "示例文件";
        final String fileSuffix = ".jpg";
        final String url = "XXXXXXX";//文件路径

        try{
            String base64Code=encoderToBase64Code(url);
            base64CodeToFile(base64Code,"D:\\BASE64编码字符串"+fileName+".txt");
            decoderToBase64Code(base64Code,"D:\\解码"+fileName+fileSuffix);
        }catch(Exception e){
            e.printStackTrace();
        }

    }


    //文件转换程BASE64编码
    public static String encoderToBase64Code(String path)throws IOException{

          File file = new File(path);
          FileInputStream input = new FileInputStream(file);
          byte[] buffer = new byte[(int)file.length()];
          input.read(buffer);
          input.close();
          System.out.print(new BASE64Encoder().encode(buffer));//打印文件经过编码后的字符串
          return new BASE64Encoder().encode(buffer);
    }


    //BASE64字符串解码并保存文件
    public static void decoderToBase64Code(String base64Code,String targetPath) throws IOException{
          byte[] buffer = new BASE64Decoder().decodeBuffer(base64Code);
          FileOutputStream out = new FileOutputStream(targetPath);
          out.write(buffer);
          out.close();



     //BASE64字符串保存成文本
     public static void base64CodeToFile(String base64Code,String targetPath) throws IOException{
           byte[] buffer = base64Code.getBytes();
           FileOutputStream out = new FileOutputStream(targetPath);
           out.write(buffer);
           out.close();
     }

    }

}

import java.io.File;
import java.io.FileInputStream;

import java.io.IOException;

		final String url = "XXXXXXX";//文件路径

		try{
			String base64Code=encoderToBase64Code(url);
			base64CodeToFile(base64Code,"D:\\BASE64编码字符串"+fileName+".txt");
			decoderToBase64Code(base64Code,"D:\\解码"+fileName+fileSuffix);
		}catch(Exception e){
			e.printStackTrace();
		}

	}


    //文件转换程BASE64编码
	public static String encoderToBase64Code(String path)throws IOException{
	
	      File file = new File(path);

		  input.read(buffer);
		  input.close();
		  System.out.print(new BASE64Encoder().encode(buffer));//打印文件经过编码后的字符串
		  return new BASE64Encoder().encode(buffer);
	}


	//BASE64字符串解码并保存文件
	public static void decoderToBase64Code(String base64Code,String targetPath) throws IOException{
	      byte[] buffer = new BASE64Decoder().decodeBuffer(base64Code);
		  FileOutputStream out = new FileOutputStream(targetPath);
		  out.write(buffer);
		  out.close();



     //BASE64字符串保存成文本
	 public static void base64CodeToFile(String base64Code,String targetPath) throws IOException{
	       byte[] buffer = base64Code.getBytes();
		   FileOutputStream out = new FileOutputStream(targetPath);
		   out.write(buffer);
		   out.close();
	 }
	
	}
