Spring what is the easiest way to return custom Http status, headers and body to Rest Client

问题

I would like to return to my Rest Client the simplest answer. Only the:

http status code 201
http status message Created
http header Content Type
http response body Custom string answer

What is the easiest way?

I've used to use ResponseEntity object this way:

return new ResponseEntity<String>("Custom string answer", HttpStatus.CREATED);,

but unfortunately, I can not simple pass http header in constructor.

I have to create HttpHeaders object and there add my custom header like this:

MultiValueMap<String, String> headers = new HttpHeaders();
headers.add(HttpHeaders.CONTENT_TYPE, MediaType.TEXT_PLAIN_VALUE);

return new ResponseEntity<String>("Custom string answer", headers, HttpStatus.CREATED);

But I am looking for something simpler. Something that could fit one line of code.

Can Anyone help?

回答1:

As already suggested from @M.Deinum this is the easiest way:

@RequestMapping("someMapping")
@ResponseBody
public ResponseEntity<String> create() {
    return ResponseEntity.status(HttpStatus.CREATED)
       .contentType(MediaType.TEXT_PLAIN)
       .body("Custom string answer");
}

I guess this will help:

@RequestMapping(value = "/createData", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)
@ResponseStatus(HttpStatus.CREATED)
@ResponseBody
public String create(@RequestBody Object input)
{
    return "custom string";
}
