java 从本地拿取图片给前端显示

直接从本地拿取图片给前端显示，直接给前端流数据：

public static void getPhoto(HttpServletResponse response, String imgUrl) throws Exception {
    String path = "你的路径" + imgUrl；
    File file = new File(path);
    FileInputStream fis;
    fis = new FileInputStream(file);

    long size = file.length();
    byte[] temp = new byte[(int) size];
    fis.read(temp, 0, (int) size);
    fis.close();
    byte[] data = temp;
    response.setContentType("image/png");
    OutputStream out = response.getOutputStream();
    out.write(data);
    out.flush();
    out.close();
