Path Variable

Like the usual Spring Web annotations, you can use the @PathVariable annotation to specify the path variables to be used in the request.

    @GetMapping(value = "/getRequest-withPathVariable/{testPathVariable}",
        produces = MediaType.APPLICATION_JSON_VALUE)
    Mono<ResponseEntity<String>> getRequestWithPathVariable(@PathVariable("testPathVariable") String pathVariable);

Note that the path variable name in the annotation should match the path variable name in the path. In the above example, the path variable name in the annotation is testPathVariable and the path variable in the path is {testPathVariable}. The path variable name in the annotation is used to bind the path variable value to the method parameter.
