Disable HTTP cache in WebFlux

Question

In Spring Boot MVC app I disable HTTP cache this way:

WebContentInterceptor cacheInterceptor = new WebContentInterceptor();
cacheInterceptor.setCacheSeconds(0);
cacheInterceptor.setUseExpiresHeader(true);
cacheInterceptor.setUseCacheControlHeader(true);
cacheInterceptor.setUseCacheControlNoStore(true);
registry.addInterceptor(cacheInterceptor);

How to do it in Spring Boot WebFlux app?

Answer 1

If you're using Spring Boot and you'd like to prevent caching for static resources, you can achieve that with the following configuration property:

spring.web.resources.cache.cachecontrol.no-store=true

If you'd like to disable caching for everything, including REST calls and views, etc; then you can implement a custom WebFilter that does just that and expose it as a bean in your application:

class NoStoreWebFilter implements WebFilter {
    @Override
    public Mono<Void> filter(ServerWebExchange exchange, WebFilterChain chain) {
        exchange.getResponse().getHeaders()
                .setCacheControl(CacheControl.noStore().getHeaderValue());
        return chain.filter(exchange);
    }
}
