如何从Spring Rest Controller发送流中的文本块？

Question

I would like to send data in chunks as and when it is ready from spring controller.

 @RequestMapping("/")
    public String home(){
         while(i=0;i<10;i++){
          //send numbers from 0 to 10 in chunks as http response
          //code to send this number as response
          Thread.sleep(50000);
        }
                }

How to achive this ?

Spring MVC can provide a servlet response object, which you can then write to. Eg :

    @RequestMapping("/")
    public void home(HttpServletResponse response) throws IOException {
        PrintWriter writer = response.getWriter();
        for (int i = 0; i < 10; i++) {
            writer.println(i);
            writer.flush();
            Thread.sleep(50000);
        }
    }
