JAVA后端接收图片
@RequestMapping("/filesUpload")
public void filesUpload(HttpServletRequest request, HttpServletResponse response,
@RequestParam MultipartFile image) throws IOException {
JsonObject json = new JsonObject();
byte[] bs = image.getBytes();
int stateInt = 1;

try {
String filePath = "你要保存的路径";
System.out.println("开始上传");
File validateCodeFolder = new File(filePath);
if (!validateCodeFolder.exists()) {
validateCodeFolder.mkdirs();
}
// 将字符串转换成二进制,用于显示图片
// 将上面生成的图片格式字符串 imgStr,还原成图片显示
String type = ".jpg";
String uuid = "文件名字";
String filename = uuid + type;
InputStream in = new ByteArrayInputStream(bs);
File file = new File(filePath, filename);// 可以是任何图片格式.jpg,.png等
FileOutputStream fos = new FileOutputStream(file);
byte[] b = new byte[1024];
int nRead = 0;
while ((nRead = in.read(b)) != -1) {
fos.write(b, 0, nRead);
}
fos.flush();
fos.close();
in.close();
System.out.println("上传成功");

json.addProperty("code", 200);
