InputStream如何写入HttpServletResponse中呢?

下文笔者讲述将InputStream写入到HttpServletResponse的方法分享,如下所示

实现思路:
    1.获取response.getOutputStream()
	2.将InputStream写入到reponse中即可

例：InputStream写入到HttpServletResponse中

response.setContentLength(getContentLength());
byte[] buffer = new byte[10240];

try (
    InputStream input = getInputStream();
    OutputStream output = response.getOutputStream();
) {
    for (int length = 0; (length = input.read(buffer)) > 0;) {
        output.write(buffer, 0, length);
    }
}
