I have a Spring Boot app with multiple controllers serving various REST methods. Each of the methods require that the same header parameter be defined. Is there a way to specify something like the following one time for all controller methods?
public ResponseEntity get(@RequestHeader(value="NAME", required = true) String name, ...) {
...
}
Thanks.

First, we used the @RequestHeader annotation to supply request headers to our controller methods. After checking out the basics, we took a detailed look at the attributes for the @RequestHeader annotation. The example code is available over on GitHub.
Spring Controller annotation is typically used in combination with annotated handler methods based on the @RequestMapping annotation. It can be applied to classes only. It's used to mark a class as a web request handler. It's mostly used with Spring MVC applications.
You can probably achieve this using @ModelAttribute, like this:
public class Something {
private name;
//...
}
@ModelAttribute("something")
public Something addSomething(@RequestHeader(value="NAME", required = true) String name) {
return new Something(name);
}
@RequestMapping("/something")
public ResponseEntity get(@ModelAttribute Something something) {
//...
}
You can implement the @ModelAttribute populating method in a single Controller or in a @ControllerAdvice class, in order to assist multiple controllers. See reference documentation.
