Freemarker和webflux错误

Question

[当我在webflux应用中使用freemarker时，总是会遇到一个例外：无法解析名称为'';;的视图]

我的FreemarkerConfig：

@Bean
public FreeMarkerConfigurer freeMarkerConfigurer() {
    FreeMarkerConfigurer configurer = new FreeMarkerConfigurer();
    configurer.setTemplateLoaderPaths("classpath:/src/main/resources/templates");
    return configurer;
}  

ViewResolver：

@Override
public void configureViewResolvers(ViewResolverRegistry registry) {
    registry.freeMarker().suffix(".ftl");
}

classpath：my classpatg

stacktrace：stacktrace

主路由器：

@Configuration
public class MainRouter {

    @Bean
    public RouterFunction<ServerResponse> route(MainHandler mainHandler){

        RequestPredicate get = RequestPredicates.GET("/news");

        return RouterFunctions.route(get, mainHandler::news);
    }
}

mainhandler：

@Component
public class MainHandler {

    private Logger logger = LoggerFactory.getLogger(MainHandler.class);

    @Autowired
    private UserService userService;

    public Mono<ServerResponse> news(ServerRequest serverRequest) {

        Mono<? extends Principal> principal = serverRequest.principal();

        return principal.flatMap(p -> {

            logger.info(p.getName());

            return userService.findByUserName(p.getName()).flatMap(user -> {
                return ServerResponse.ok().render("news", Map.of("currentUser", user, "messages", userService.findMessages(user)))
                        .onErrorResume(error->{
                    logger.info(error.getLocalizedMessage());
                    return ServerResponse.badRequest().build();
                });
            });

        });
    }
}

我想应该是"classpath:/templates"在构建项目时/src/main/resources/部分不见了，就像输出jar将在存档根目录下直接包含templates目录。
