How to get access to HTTP header information in Spring MVC REST controller?
When you annotate a parameter with @RequestHeader
, the parameter retrieves the header information. So you can just do something like this:
@RequestHeader("Accept")
to get the Accept
header.
So from the documentation:
@RequestMapping("/displayHeaderInfo.do")
public void displayHeaderInfo(@RequestHeader("Accept-Encoding") String encoding,
@RequestHeader("Keep-Alive") long keepAlive) {
}
The Accept-Encoding
and Keep-Alive
header values are provided in the encoding
and keepAlive
parameters respectively.
And no worries. We are all noobs with something.
You can use the @RequestHeader
annotation with HttpHeaders
method parameter to gain access to all request headers:
@RequestMapping(value = "/restURL")
public String serveRest(@RequestBody String body, @RequestHeader HttpHeaders headers) {
// Use headers to get the information about all the request headers
long contentLength = headers.getContentLength();
// ...
StreamSource source = new StreamSource(new StringReader(body));
YourObject obj = (YourObject) jaxb2Mashaller.unmarshal(source);
// ...
}
