后端返回图片路径不展示问题

需要先转换为base64编码返回

 File imageFile  = new File(one.getValuess().toString());
            //通过ImageIO把文件读取成BufferedImage对象
            BufferedImage bufferedImage = null;
            try {
                bufferedImage = ImageIO.read(imageFile);
            } catch (IOException e) {
                throw new RuntimeException(e);
            }
            //构建字节数组输出流
            ByteArrayOutputStream  baos = new ByteArrayOutputStream();
            //写入流
            String suffix =imageFile.getName().substring(imageFile.getName().lastIndexOf(".") + 1);
            try {
                ImageIO.write(bufferedImage, suffix, baos);
            } catch (IOException e) {
                throw new RuntimeException(e);
            }
            //通过字节数组流获取字节数组
            byte[] byte1s = baos.toByteArray();
            //获取JDK8里的编码器Base64.Encoder转为base64字符
            String s1 = Base64.getEncoder().encodeToString(byte1s);
