http响应头设置

    protected void service(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {// 设置响应头数据response.setHeader(null, "HTTP/1.1 200 OK");response.setHeader("Server", "Apache-Coyote/1.1");response.setHeader("Date", "Sun, 10 Jan 2016 04:09:02 GMT");// 当有下面这一个头设置时，访问得不到想要的json数据，不设置就可以访问并得到json数据// response.setHeader("Transfer-Encoding", "chunked");response.setHeader("Content-Type", "application/json;charset=UTF-8");// 本地的一个json数据文件File file = new File("D:/Environments/test.json");InputStream in = new FileInputStream(file);byte[] buffer = new byte[1024];int num = 0;OutputStream out = response.getOutputStream();while((num=in.read(buffer))!=-1){out.write(buffer, 0, num);}if(in!=null){in.close();}}

在上述的响应头Transfer-Encoding设置了，为什么不能够得到json数据？未知

D:/Environments/test.json
