使用Spring WebFlux的header API版本控制的干净解决方案？

@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface ApiVersion {
    int value();
}

@RestController
@RequestMapping("/api")
public class MyController {

    @GetMapping("/data")
    @ApiVersion(1)
    public Mono<String> getDataV1() {
        // 处理版本1的逻辑
    }

    @GetMapping("/data")
    @ApiVersion(2)
    public Mono<String> getDataV2() {
        // 处理版本2的逻辑
    }
}

@Component
@Order(1)
public class ApiVersionInterceptor implements HandlerInterceptor {

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        if (handler instanceof HandlerMethod) {
            HandlerMethod handlerMethod = (HandlerMethod) handler;
            ApiVersion apiVersion = handlerMethod.getMethodAnnotation(ApiVersion.class);
            if (apiVersion != null) {
                int version = apiVersion.value();
                String versionHeader = request.getHeader("Api-Version");
                if (versionHeader != null && Integer.parseInt(versionHeader) == version) {
                    return true;
                } else {
                    response.setStatus(HttpStatus.BAD_REQUEST.value());
                    return false;
                }
            }
        }
        return true;
    }
}

@Configuration
public class WebConfig implements WebMvcConfigurer {

    @Autowired
    private ApiVersionInterceptor apiVersionInterceptor;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(apiVersionInterceptor);
    }
}
