Spring @PathVariable get everything after /

Question

I have some url of type: "/something/some/random/path"

For all urls that start with "/something/" I want everything after it to be considered as a path variable

@RequestMapping("/something/{path}")
public MyCustomObj get(@PathVariable("path") String path){
    System.out.println(path); // "some/random/path"
}

I know is possible with redirect but is not what I need. I tried with regexp but doesn't seems to work

@RequestMapping("/spring-web/{path:.*}

There is any way to do that, or maybe some work arrounds?

Thanks

I see 2 workarounds here:

1. @RequestMapping("/something/**") and inject HttpServletRequest: public MyCustomObj get(HttpServletRequest) and manually parse path using request.getServletPath()

2. Do the same as above using custom HandlerMethodArgumentResolver. You could create custom annotation for this e.g. @MyPath:

   public class MyPathResolver implements HandlerMethodArgumentResolver {
   
       @Override
       public boolean supportsParameter(MethodParameter parameter) {
           return parameter.hasParameterAnnotation(MyPath.class);
       }
   
       @Override
       public Object resolveArgument(MethodParameter parameter, ModelAndViewContainer mavContainer,
       NativeWebRequest webRequest, WebDataBinderFactory binderFactory) throws Exception {
           return ((ServletWebRequest) webRequest).getRequest().getServletPath().split("/")[2]; 
          //you can do whatever you want here, you can even get a value from your RequestMapping annotation 
            and customize @MyPath value as you want
       }
   }
   

Then you can inject your newly created annotation like this: public MyCustomObj get(@MyPath String path). Remember to register your argument resolver.
