spring-boot-starter-webflux（Spring Boot v2.0.0.M2）已像在资源中的静态文件夹中提供静态内容一样进行配置。但它不会转发到索引.html。在Spring MVC中，可以像这样配置：spring-boot-starter-web

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

如何在Spring Webflux中做到这一点？

答案 1

在 WebFilter 中执行此操作：

@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);
  }
}

答案 2

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).bodyValue(indexHtml));
}
