问题 I want to use a reactive client (Reactive WebSocketClient i.e ReactorNettyWebSocketClient) to talk to a server which I don't know if it is reactive or not. Does it make sense to use a reactive client to talk to a server which is not reactive? I tried to connect to a server probably not reactive, and I got this error: io.netty.handler.codec.http.websocketx.WebSocketHandshakeException: Invalid handshake response getStatus: 999 Unknown at io.netty.handler.codec.http.websocketx

问题 I have a springboot project which uses Springboot Resttemplate. We have moved to springboot 2.0.1 from 1.5.3 and we are trying to make the rest calls from it asynchronous by using WebClient. We used to process the string received using Resttemplate as given below. But WebClient returns only data in Mono or Flux. How can I get the data as String. Already tried block() method , but it does asynchronous calls. @Retryable(maxAttempts = 4, value = java.net.ConnectException.class, backoff =

问题 Could someone help me to understand the difference between Mono.defer(), Mono.create() and Mono.just()? How to use it properly? 回答1: Mono.just(value) is the most primitive - once you have a value you can wrap it into a Mono and subscribers down the line will get it. Mono.defer(monoSupplier) lets you provide the whole expression that supplies the resulting Mono instance. The evaluation of this expression is deferred until somebody subscribes. Inside of this expression you can additionally use

问题 I am new to Spring Webflux. I want to use WebFilter to do authentication checking. So, the idea is intercepting the request, checking the Authorization header, and propagate the request Here is what I have tried to do. I have successfully intercept the request and check whether the header is correct or not. public class AuthWebFilter implements WebFilter { @Override public Mono<Void> filter(ServerWebExchange exchange, WebFilterChain chain) { log.info("Request {} called", exchange.getRequest()

问题 Great thx for viewing my question) I have some strange subject: my spring boot tests don't work. They start successfully but always throwing 403 HTTP status when making the requests to any controller I have some project with next dependencies: buildscript { ext.kotlin_version = '1.3.71' dependencies { classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.71" classpath "org.springframework.boot:spring-boot-gradle-plugin:2.2.1.RELEASE" classpath "com.google.cloud.tools.jib:com.google.cloud

问题 I'm using Spring RequestContextHolder in the controller and it works fine. But in the unit test I get java.lang.IllegalStateException using WebTestClient . Here is an example: package demo.reactive.controller; import org.springframework.http.ResponseEntity; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; import org.springframework.web.context.request.RequestContextHolder; import reactor.core.publisher.Mono;
