Could not resolve view with name 'streamrecords' in servlet with name 'spring'

I am using a simple stream interger number from controller example using Spring 4, Java 8, Tomcat 7.

CODE: 

package com.entrib.emg.server.controller.rest;
import java.io.IOException;
import java.io.OutputStream;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.mvc.method.annotation.StreamingResponseBody;

@Controller
public class StreamRecordsController {

    @RequestMapping(value = "/streamrecords", method = RequestMethod.GET)
    public StreamingResponseBody handleRequest ()
            throws Exception {

        return new StreamingResponseBody() {
            @Override
            public void writeTo (OutputStream out) throws IOException {
                for (int i = 0; i < 1000; i++) {
                    out.write((Integer.toString(i) + " - ")
                                        .getBytes());
                    out.flush();
                    try {
                        Thread.sleep(5);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
            }
        };
    }
}

ERROR:

QUESTION:

What am I missing over here.

EXPECTATIONS:

This is just a simple rest API code, I am expecting a stream of integers streamed from this controller when the API is hit from either browser or postman.

UPDATED

------------------------------------------------

When I added @ResponseBody, I am getting below error,

Type Status Report

Description The target resource does not have a current representation that would be acceptable to the user agent, according to the proactive negotiation header fields received in the request, and the server is unwilling to supply a default representation.
Solution

  • You are missing @ResponseBody on your servlet method or alternatively you can mark your class with @RestController
