Try this :

@RestController
public class SampleController { 
    @RequestMapping("/req")
    public String performReqest(){
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);        
        JsonObject properties = new JsonObject();
        properties.addProperty("no", "123");
        properties.addProperty("name", "stackoverflow");
        HttpEntity<String> request = new HttpEntity<>(properties.toString(), headers);
        RestTemplate restTemplate = new RestTemplate();
        String response = restTemplate.postForObject("http://localhost:4040/student", request, String.class);
        return "Response from Server is : "+response;       
    }

    @RequestMapping("/student")
    public String consumeStudent(@RequestBody Student student){
        System.out.println(student);
        return "Hello.."+student.name;
    }   
}

class Student{
    public int no;
    public String name; 
    public Map<String,String> properties;   
}

Don't forgot to move Student class and change all field to private with require getters and setters. Above code is only for demo purpose.
