问题 I cannot access the java.security.Principal authenticated by my CAS authentication system. serverWebExchange.getPrincipal() is allways empty. In fact this is the implementation of DefaultServerWebExchange : @Override public <T extends Principal> Mono<T> getPrincipal() { return Mono.empty(); } Another implementation of ServerWebExchange is ServerWebExchangeDecorator and its documentation says: Note: if the purpose for using a decorator is to override properties like getPrincipal() , consider

问题 I am looking at some examples of reactive web applications and i am seeing them like this @RequestMapping(value = "/{id}", method = RequestMethod.GET) @ResponseBody public Mono<Person> findById(...) { return exampleService.findById(...); } @RequestMapping(method = RequestMethod.GET, produces = MediaType.TEXT_EVENT_STREAM_VALUE) @ResponseBody public Flux<Person> findAll() { Flux<Person> persons = exampleService.findAll(); return persons; } When i am reading about the Mono and Flux in the

问题 I am receiving some XML payload in a POST request and want to see the payload as received for debugging purposes. Below (my custom WebFilter) code logs the URI and request headers as expected but not the request body/payload, must be something wrong with my reactive code - final ServerHttpRequest request = exchange.getRequest(); ByteArrayOutputStream baos = new ByteArrayOutputStream(); LOGGER.info("Request: uri={}", request.getURI()); LOGGER.info("Request: headers={}", request.getHeaders()

问题 I use Spring WebFlux (Project Reactor) and I'm facing the following problem: I have to get some data from db to use them to call another service - everything in one stream. How to do that? public Mono<MyObj> saveObj(Mono<MyObj> obj) { return obj .flatMap( ob-> Mono.zip( repo1.save( ...), repo2 .saveAll(...) .collectList(), repo3 .saveAll(...) .collectList()) .map(this::createSpecificObject)) .doOnNext(item-> createObjAndCallAnotherService(item)); } private void createObjAndCallAnotherService

问题 I'm building a prototype for a new application using Spring Webflux and Kotlin. Spring Webflux contains a WebTestClient for unit tests. According to the documentation I should be able to test the results of a REST call like this: @Test fun getVersion_SingleResult_ContentTypeJson_StatusCodeOk_ContentEqualsVersion() { //given var version = Version("Test", "1.0") val handler = ApiHandler(version!!) val client = WebTestClient.bindToRouterFunction(ApiRoutes(handler).apiRouter()).build() //expect

问题 Coming from .NET and Node I really have a hard time to figure out how to transfer this blocking MVC controller to a non-blocking WebFlux annotated controller? I've understood the concepts, but fail to find the proper async Java IO method (which I would expect to return a Flux or Mono). @RestController @RequestMapping("/files") public class FileController { @GetMapping("/{fileName}") public void getFile(@PathVariable String fileName, HttpServletResponse response) { try { File file = new File

问题 In non reactive applications we could do SecurityContextHolder.getContext().setAuthentication(authentication); to authenticate a request programmatically. What would be the equivalent with Webflux? public class ReactiveServiceAuthenticationFilter implements WebFilter { private final ReactiveAuthenticationManager authenticationManager; public ReactiveServiceAuthenticationFilter(ReactiveAuthenticationManager authenticationManager){ this.authenticationManager = authenticationManager; } @Override

问题 I am trying to use Rsocket with websocket in one of my POC projects. In my case user login is not required. I would like to send a message only to certain clients when I receive a message from another service. Basically, my flow goes like this. Service A Service B |--------| websocket |------------------| Queue based comm |---------------| | Web |----------------->| Rsocket server |--------------------->| Another | | |<-----------------| using Websocket |<---------------------| service | |---
