Question

How to get request header value from http request in spring mvc based on custom annotation condition on Field level Element type without using any handlerMapping object?

Answer 1

I don't really get what you're asking, Spring MVC already offers an annotation to map request headers, see the doc

@RequestMapping("/displayHeaderInfo.do")
public void displayHeaderInfo(@RequestHeader("Accept-Encoding") String encoding,
        @RequestHeader("Keep-Alive") long keepAlive) {
    //...
}
