How to set response header in spring mvc

Question

I have a method in which i want to set response header cache-control and pragma :-

public String addUser(@Valid User user, BindingResult bindingResult)
{
    if(bindingResult.hasErrors())
    {
        bindingResult.getFieldError();
        return"edit";
    }
    return "redirect:/welcome/profile/"+user.getName();
}

In this method i want to set cache-control and pragma like we do in simple servlet code using HttpservletResponse calling setHeader method :-

response.setHeader("Cache-Control","no-cache,no-store,must-revalidate");
    response.setHeader("Pragma","no-cache");
    response.setDateHeader("Expires", 0);

I searched spring docs and could not find any direct way to do it, but I found this:-

@RequestMapping("/something")
public ResponseEntity<String> handle(HttpEntity<byte[]> requestEntity) throws UnsupportedEncodingException 
{
    String requestHeader = requestEntity.getHeaders().getFirst("MyRequestHeader"));
    byte[] requestBody = requestEntity.getBody();
    HttpHeaders responseHeaders = new HttpHeaders();
    responseHeaders.set("MyResponseHeader", "MyValue");
    return new ResponseEntity<String>("Hello World", responseHeaders, HttpStatus.CREATED);
}

But I dont know how to use it

If you want to set headers for every response for a controller you can use @ModelAttribute annotation.

@ModelAttribute
public void setVaryResponseHeader(HttpServletResponse response) {
    response.setHeader("Vary", "Accept");
}

  public String addUser(@Valid User user, BindingResult bindingResult,HttpServletRequest request,HttpServletResponse response)
  {
       if(bindingResult.hasErrors())
       {
            bindingResult.getFieldError();
            return"edit";
      }
      response.setHeader("Cache-Control","no-cache,no-store,must-revalidate");
      response.setHeader("Pragma","no-cache");
      response.setDateHeader("Expires", 0);
      return "redirect:/welcome/profile/"+user.getName();
  }

Since Spring v. 4.1:

@RequestMapping("/something")
public ResponseEntity<MyClass> handle()
{
return ResponseEntity.status(HttpStatus.CREATED)
              .header("header", "value")
              .body(new MyClass());
}

how can I set `n` number of headers say from an array or a list? – Hari Shankar Nov 27 '18 at 09:27
You can use ResponseEntity.headers( **HttpHeaders** ).body( ... ). The class HttpHeaders implements a MultiValueMap interface and has methods **addAll(MultiValueMap values)** and **addAll(K key, List extends V> values)** – Антон Терёшин Dec 08 '18 at 13:11

You can manually set headers as follows.

imports:

import org.springframework.http.HttpHeaders;

code:

public ResponseEntity<Map<String, Object>> doSomething() {
   ...
HttpHeaders respHeaders = new HttpHeaders();
respHeaders.add("Pragma", "no-cache");
respHeaders.add("Cache-Control","no-cache,no-store,must-revalidate");
return new ResponseEntity<Map<String, Object>>(respHeaders, HttpStatus.OK);
}
