Java 将多个图像转换为字节数组

我试图将响应作为多个图像字节数组发送给另一个应用程序

我从数据库中获取车辆图像列表，并将其转换为字节数组

ByteArrayInputStream instream = null;
ServletOutputStream out = null ;
for(Vehicle vehicle : vehicleList)
{
   byte[] imageInByte = null;
   VehicleImage vehicleImage=VehicleImagePeer.doSelectFirst(c.add(VehicleImagePeer.VEHICLE_ID, getId()));
   c.clear();
   String path = TaxiApp.getConfigValue("IMAGE.PATH")+vehicleImage.getPath();
   System.out.print(path);
   BufferedImage originalImage = ImageIO.read(new File(path));
   ImageIO.write(originalImage, "png", baos);
   imageInByte = baos.toByteArray();
   baos.close();

out = response.getOutputStream();
response.setContentLength(imageInByte.length);
response.setCharacterEncoding(Charset.forName("UTF-8").name());
int bufferSize = response.getBufferSize();
byte[] buffer = new byte[bufferSize];
instream = new ByteArrayInputStream(imageInByte);
TaxiApp.logprintf("Total page size in bytes: %s and default response bufferSize in bytes: %s%n", new Object[] 
{
   Integer.valueOf(imageInByte.length), Integer.valueOf(bufferSize) 
});
int length = 0;
while ((length = instream.read(buffer, 0, bufferSize)) != -1)
{
out.write(buffer, 0, length);
out.flush();
}

使用此代码，我将所有图像转换为字节数组

现在我需要作出回应。 我使用此代码来响应

ByteArrayInputStream instream = null;
ServletOutputStream out = null ;
for(Vehicle vehicle : vehicleList)
{
   byte[] imageInByte = null;
   VehicleImage vehicleImage=VehicleImagePeer.doSelectFirst(c.add(VehicleImagePeer.VEHICLE_ID, getId()));
   c.clear();
   String path = TaxiApp.getConfigValue("IMAGE.PATH")+vehicleImage.getPath();
   System.out.print(path);
   BufferedImage originalImage = ImageIO.read(new File(path));
   ImageIO.write(originalImage, "png", baos);
   imageInByte = baos.toByteArray();
   baos.close();

out = response.getOutputStream();
response.setContentLength(imageInByte.length);
response.setCharacterEncoding(Charset.forName("UTF-8").name());
int bufferSize = response.getBufferSize();
byte[] buffer = new byte[bufferSize];
instream = new ByteArrayInputStream(imageInByte);
TaxiApp.logprintf("Total page size in bytes: %s and default response bufferSize in bytes: %s%n", new Object[] 
{
   Integer.valueOf(imageInByte.length), Integer.valueOf(bufferSize) 
});
int length = 0;
while ((length = instream.read(buffer, 0, bufferSize)) != -1)
{
out.write(buffer, 0, length);
out.flush();
}

我有个问题。 响应只能发送第一个图像字节数组。但我需要发送所有图像字节数组…请解决此问题
