Spring全局范围可选路径变量

Question

i need to create a global scope optional path variable on my website using Spring, so the same controller could handle a requests with URL's like

https://website.com/something

and

https://website.com/something/5

And i managed to do that this way

@RequestMapping("/something")
public class SomethingController {

  @RequestMapping(value = {"", "/{id}) //<-- important line here
  public Model something([...]) {
    return [...]

But let's say that i have 50 controllers in my application and i don't wan't to modify each and every one of them. Is there any simpler way to accomplish what i need? (application-scope or controller class-scope)

You can try to extend this controllers from Base Controller that is annotated with @RequestMapping (not so flexible), or you can try design patterns like Decorator Pattern. https://www.tutorialspoint.com/design_pattern/decorator_pattern.htm
