2019-12-19 jersey upload （input

inputStream，FormDataContentDisposition

问题描述：使用jersey框架上传，通过inputstream 不能获取到输入流的字节大小

解决：将输入流写入到输出流中读取

byte[] buffer =new byte[1024];

ByteArrayOutputStream outSteam =new ByteArrayOutputStream();

int ls = -1;

try {

while ((ls = inputStream.read(buffer)) != -1) {

outSteam.write(buffer,0, ls);

}

outSteam.close();

inputStream.close();

}catch (IOException e) {

e.printStackTrace();

}

int size = outSteam.size();
