How to Set Response Header Values ​​in Spring Service Methods for Boot?

Question

Newbie question ... I am creating my first Spring Boot restful support service. For my calm service design, some data should be returned in the response header.

How to set response header values ​​inside a controller class method?

Answer 1

From the spring documentation:

@RequestMapping("/handle")
public ResponseEntity<String> handle() {
    URI location = ...;
    HttpHeaders responseHeaders = new HttpHeaders();
    responseHeaders.setLocation(location);
    responseHeaders.set("MyResponseHeader", "MyValue");
    return new ResponseEntity<String>("Hello World", responseHeaders, HttpStatus.CREATED);
}

Source: https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/http/ResponseEntity.html

Answer 2

HttpServletResponse. API- Servlet, . ResponseEntity HttpEntity.

HttpHeaders headers = new HttpHeaders();
headers.add("1", "uno");

return new ResponseEntity<>(headers, HttpStatus.OK);
