Question

spring-boot-starter-webflux（Spring Boot v2.0.0.M2）已经像在spring-boot-starter-web中一样配置，以便在资源中的静态文件夹中提供静态内容。但它并没有转发到index.html。在Spring MVC中，可以像这样配置：

@Override
public void addViewControllers(ViewControllerRegistry registry) {
    registry.addViewController("/").setViewName("forward:/index.html");
}

如何在Spring Webflux中执行此操作？

Answer 1

在WebFilter中执行：

@Component
public class CustomWebFilter implements WebFilter {
  @Override
  public Mono<Void> filter(ServerWebExchange exchange, WebFilterChain chain) {
    if (exchange.getRequest().getURI().getPath().equals("/")) {
        return chain.filter(exchange.mutate().request(exchange.getRequest().mutate().path("/index.html").build()).build());
    }

    return chain.filter(exchange);
  }
}

Answer 2

有ticket in the Spring Boot tracker for this。

Answer 3

import static org.springframework.web.reactive.function.server.RequestPredicates.GET;
import static org.springframework.web.reactive.function.server.RouterFunctions.route;
import static org.springframework.web.reactive.function.server.ServerResponse.ok;

@Bean
public RouterFunction<ServerResponse> indexRouter(@Value("classpath:/static/index.html") final Resource indexHtml) {
return route(GET("/"), request -> ok().contentType(MediaType.TEXT_HTML).syncBody(indexHtml));
}

Answer 4

使用WebFlux Kotlin DSL也是如此：

@Bean
open fun indexRouter(): RouterFunction<ServerResponse> {
    val redirectToIndex =
            ServerResponse
                    .temporaryRedirect(URI("/index.html"))
                    .build()

    return router {
        GET("/") {
            redirectToIndex // also you can create request here
        }
    }
}
