spring mvc獲取header

兩種方法： 
1.在方法參數中加入@RequestHeader 
2.在類級別注入HttpServletRequest 

建議使用第二種方法，這樣可避免每個方法都加入HttpHeaders參數 

 

@Controller
@RequestMapping("/hello")
public class HelloController {
     @Autowired
     private HttpServletRequest request;

     @RequestMapping(value="/printname/{name}", method=RequestMethod.GET)
     public String printName(@PathVariable String name,
              @RequestHeader HttpHeaders headers) {
          System.out.println("from request:" + request.getHeader("code"));
          System.out.println("from parameter:" + headers.getFirst("code"));

          return "hello";
     }
}
