java base64 json_图片转base64使用JSON传输

要传输的JSON格式：

后台代码：

@RequestMapping(value = {"/photoJson"})

@ResponseBodypublicPhysicalIdCheckDto testPhotoJson(@RequestBody PhysicalIdCheckDto physicalIdCheckDto) {

String imgStr=physicalIdCheckDto.getCargoReceiptNo();

BASE64Decoder decoder= newBASE64Decoder();try{byte[] b =decoder.decodeBuffer(imgStr);for (int i = 0; i < b.length; ++i) {if (b[i] < 0) {

}

}

OutputStream out= new FileOutputStream("E:\\img\\logo.jpg");

out.write(b);

out.flush();

out.close();

}catch(Exception e) {

}

System.out.println("输出JSON："+physicalIdCheckDto);returnphysicalIdCheckDto;

}

base64转图片

/*** @Description: 将base64编码字符串转换为图片

* @Author:

* @CreateTime:

*@paramimgStr base64编码字符串

*@parampath 图片路径-具体到文件

*@return

*/

public static booleangenerateImage(String imgStr, String path) {if (imgStr == null)return false;

BASE64Decoder decoder= newBASE64Decoder();try{//解密

byte[] b =decoder.decodeBuffer(imgStr);//处理数据

for (int i = 0; i < b.length; ++i) {if (b[i] < 0) {

b[i]+= 256;

}

}

OutputStream out= newFileOutputStream(path);

out.write(b);

out.flush();

out.close();return true;

}catch(Exception e) {return false;

}

}

图片转base64

/*** @Description: 根据图片地址转换为base64编码字符串

* @Author:

* @CreateTime:

*@return

*/

public staticString getImageStr(String imgFile) {

InputStream inputStream= null;byte[] data = null;try{

inputStream= newFileInputStream(imgFile);

data= new byte[inputStream.available()];

inputStream.read(data);

inputStream.close();

}catch(IOException e) {

e.printStackTrace();

}//加密

BASE64Encoder encoder = newBASE64Encoder();returnencoder.encode(data);

}

测试：

/*** 示例*/

public static voidmain(String[] args) {

String strImg= getImageStr("F:/86619-106.jpg");

System.out.println(strImg);

generateImage(strImg,"F:/86619-107.jpg");

}
