java - Freemarker 和 webflux 错误

Question

当我在 webflux 应用程序中使用 freemarker 时，我总是遇到一个异常:无法解析名称为“”的 View ；

我的 FreemarkerConfig:

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

View 解析器:

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

类路径: my classpatg

堆栈跟踪: 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);
    }
}

主处理程序:

@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" 当您构建项目时，/src/main/resources/ 部分就消失了，就像输出jar 将在存档根目录下直接包含 templates 目录。
