Spring是将自定义Http状态，标头和正文返回给Rest Client的最简单方法 [英] Spring what is the easiest way to return custom Http status, headers and body to Rest Client

问题描述

我想向我的Rest Client返回最简单的答案. 只有:

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

• http状态码 201
• http状态消息已创建
• http标头内容类型
• http响应正文自定义字符串答案

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

最简单的方法是什么?

我曾经以这种方式使用ResponseEntity对象:

I've used to use ResponseEntity object this way:

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

但是不幸的是，我不能简单地在构造函数中传递http标头.

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

我必须创建HttpHeaders对象，并在其中添加我的自定义标头，如下所示:

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);

但是我正在寻找更简单的方法.可能适合一行代码的东西.

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

任何人都可以帮忙吗?

推荐答案

正如@ M.Deinum所建议的那样，这是最简单的方法:

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");
}
