Spring返回自定義header及Content-type
阿新 • • 發佈:2019-01-26
在使用Spring中, 如果直接對Resopnse中的content-type賦值,會被系統忽略, 如:
@GetMapping("/e2")
public String getE2( HttpServletResponse response) throws IOException {
response.setHeader("content-type", "application/x-javascript; charset=gb2312");
response.setHeader("selfHeader","selfHeaderValue");
return "common body" ;
}
//返回值
此時Response描述如下
Content-Length: 11
Content-Type: text/html;charset=UTF-8
Date: Fri, 10 Aug 2018 01:11:47 GMT
selfHeader: selfHeaderValue
如果業務需要設定自定義content-type可以使用如下兩種方法
方法一 使用Response.getOutputStream
@GetMapping("/e3")
@IgnoreSecurity
public void getE3(HttpServletResponse reponse) throws IOException {
reponse.setHeader("content-type", "application/x-javascript; charset=gb2312");
reponse.setHeader("selfHeader","selfHeaderValue");
reponse.getOutputStream().print("this is body");
}
返回結果如下;
Content-Length: 12
Content-Type: application/x-javascript;charset=gb2312
Date : Fri, 10 Aug 2018 01:29:46 GMT
selfHeader: selfHeaderValue
方法二,使用ResponseEntity
@GetMapping("/e")
public ResponseEntity<String> getE() {
HttpHeaders headers = new HttpHeaders();
headers.add("head1", "head1value");
headers.add("Content-Type", "application/x-javascript; charset=gb2312");
return ResponseEntity.status(200).headers(headers).body("this is body");
}
返回結果如下;
Content-Length: 12
Content-Type: application/x-javascript;charset=gb2312
Date: Fri, 10 Aug 2018 01:31:52 GMT
head1: head1value
