Reading RequestMapping wildcard in webflux application-CodePudding

I am trying to obtain the wildcard value from a controller's @requestMapping within a Spring boot webflux application:

@Controller
@RequestMapping("/template/**")
public class TemplateController {
    @GetMapping
    public Mono<String> getTemplate ( ... ) {
        String path = ...     // obtain the value of ** in the @RequestMapping
        return Mono.just(path);
    }
}

Everything I have found regarding reading such a value is for an MVC application; those solutions don't work for a webflux application.

How does one access this value within a webflux context? I would prefer an annotation-based approach for reusability, but any solution would do.

CodePudding user response：

You could get the path from ServerHttpRequest that could be obtained from ServerWebExchange passed to the controller method. From ServerHttpRequest you can access to a structured representation of the full request path

@GetMapping("/endpoint")
public Mono<Void> endpoint(ServerWebExchange serverWebExchange) {
    ServerHttpRequest request = serverWebExchange.getRequest();

    RequestPath path = request.getPath();
    String value = path.value();

    return Mono.empty();
}

With this you can play around the methods of RequestPath, maybe it helps
