I'm having trouble connecting the webflux webclient to my endpoint.
In my controller, I'm trying to expose a hot stream of Chocolate DTO's.
When I try to call the endpoint with postman, it works.
This sentence exists because Stackoverflow wants me to add more text, because there is too much code in my question, sorry for the inconvience.
#RestController
public class HotChocolateController {
#GetMapping(value = "/stream/chocolate", produces = MediaType.APPLICATION_STREAM_JSON_VALUE)
public Flux<Chocolate> chocolateStream() {
return Flux.interval(Duration.ofMillis(500))
.map(l -> Chocolate.builder()
.id(String.valueOf(System.currentTimeMillis()))
.name("Hot Chocolate")
.build())
.log();
}
}
Then I'm trying to test my setup with an unit test:
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
class ReactiveEndpointTests {
private final WebClient client = WebClient.builder().baseUrl("http://localhost:8080").build();
#Test
public void testHotChocolate(){
Flux<Chocolate> chocolateSource = client.get().uri("/stream/chocolate").retrieve().bodyToFlux(Chocolate.class);
chocolateSource.subscribe(chocolate -> System.out.println());
}
When I run this test, I get the following exception:
reactor.core.Exceptions$ErrorCallbackNotImplemented: java.lang.NullPointerException

Do you have any idea why this may happen?
You are just subscribing for the stream and immediately exiting the test method.
You can change the method to something like the code below and you'll be able to see the result of the get request:
#Test
public void testHotChocolate(){
Flux<String> chocolateSource =
client.get()
.uri("/stream/chocolate")
.retrieve()
.bodyToFlux(String.class)
.doOnNext(System.out::println);
chocolateSource.blockLast();
}

I have an error with Apache Camel when starting Spring boot
Can someone tell me how can I fix it ?
Thank you !

I tried to make a simple REST API using Spring Boot and Apache Camel
WebClient configuration (minimized reproducible use case, tested with different durations, no effect):
public WebClient createWebClient() {
ConnectionProvider provider = ConnectionProvider.builder("WebClientProvider")
.maxConnections(2)
.maxIdleTime(Duration.ofSeconds(10))
.maxLifeTime(Duration.ofSeconds(20))
.pendingAcquireTimeout(Duration.ofSeconds(10))
.evictInBackground(Duration.ofSeconds(10))
.build();
HttpClient httpClient = HttpClient.create(provider).option(ChannelOption.CONNECT_TIMEOUT_MILLIS, 5000);
ReactorClientHttpConnector reactorClientHttpConnector = new ReactorClientHttpConnector(httpClient);
return WebClient.builder()
.clientConnector(reactorClientHttpConnector)
.build();
}
Usage of the client, as a GET to a public cloud service provider:
public Flux<SomeClass> doGetSomething() {
return webClient.get()
.uri(buildUri())
.accept(MediaType.APPLICATION_JSON)
.retrieve()
.bodyToMono(byte[].class)
.flatMapMany(byteArray -> Flux.fromArray(byteArrayToModel(byteArray, SomeClass[].class)))
.onErrorResume(e -> {
return Flux.error(new RuntimeException("Failed to call get", e));
});
}

Test mechanism:
GET requests through insomnia to the reactive web app (clicking with the mouse on Send button continuously until it fails), requests failing intermittently, at random intervals with no obvious (for me), causes.
Any ideas how to solve this?

P.S.
Debugged internal libraries workflow, and got here, in reactor netty http:
#Bean
public SecurityWebFilterChain securityWebFilterChain(
ServerHttpSecurity http,
ReactiveAuthenticationManager jwtAuthenticationManager,
ServerAuthenticationConverter jwtAuthenticationConverter
) {
AuthenticationWebFilter authenticationWebFilter = new AuthenticationWebFilter(jwtAuthenticationManager);
authenticationWebFilter.setServerAuthenticationConverter(jwtAuthenticationConverter);
return http
.addFilterAt(authenticationWebFilter, SecurityWebFiltersOrder.AUTHENTICATION)
.securityMatcher(
new NegatedServerWebExchangeMatcher(
new OrServerWebExchangeMatcher(
ServerWebExchangeMatchers.pathMatchers(ALLOWED_URLS.toArray(new String[0])),
ServerWebExchangeMatchers.pathMatchers(HttpMethod.OPTIONS, "/**")
)
)
)
.httpBasic()
.disable()
.csrf()
.disable()
.formLogin()
.disable()
.logout()
.disable()
.exceptionHandling()
.authenticationEntryPoint((exchange, e) -> {
if (e.getCause() instanceof AccessDeniedException) {
throw new ForbiddenException(e);
}
throw new UnauthorizedException(e);
})
.and()
.authorizeExchange()
.pathMatchers("/api/auth/password").hasAnyRole(RolesList.SUPER_ADMIN.name(), RolesList.ADMIN.name())
.pathMatchers("/api/client/**").hasRole(RolesList.SUPER_ADMIN.name())
.pathMatchers("/api/user/**").hasRole(RolesList.SUPER_ADMIN.name())
.pathMatchers("/api/**").authenticated() //entire server side app will be kept here
.anyExchange().authenticated()
.and()
.build();
}
#Configuration
#EnableWebFlux
public class CorsGlobalConfiguration implements WebFluxConfigurer {
private final NetworkProperties networkProperties;
public CorsGlobalConfiguration(NetworkProperties networkProperties) {
this.networkProperties = networkProperties;
}
#Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/api/client/search")
.allowedOrigins(networkProperties.getAllowedOrigins())
.allowedMethods("POST", "OPTIONS");
}
}
Above are my spring security config and cors config.
When super admin accessing /api/client/search he is getting success response.
But when admin is trying to access he is getting Cors error instead of access denied.
What am i missing here?
Below is the exception stack trace which very strange according to exception my exception handler is creating response but browser displaying cors error instead of Access denined.
Again same thing is working fine for super admin

Note: "myhostname.service" is due to I am using consul and I can ping myhostname.service also can connect to it using "redis-cli -c -h myhostname.service -p 6379" command.
My code to connect to redis is,

Since I was getting exception at java.net.InetAddress.getByName("hostname") I tried,
running a redis-cli from my app container to connect to redis cluster containers it was successful.(as mentioned above.)
Since I was getting exception at java.net.InetAddress.getByName("hostname") I tried same method from inside of my app container using my redis hostname. It was successful and did not throw UnknownHostException.
Pinging to the redis host from app container works.
I did set up redis-cluster on local machine it works fine with above code only change was I provided 127.0.0.1:6379 instead of hostname.service:6379.
I am using spring-boot-starter-parent:2.0.3.RELEASE and lettuce-core:5.0.4. Is there any issue with the code?
I can not say this answers this question completely but got the reason for the issue. Issue is when app containers startup, redis containers/service is not still registered with the consul, so look up for redis containers with the lookup name say "master1.redis.service" returns UnknownHostException. But since I was running redis-cli and ping after a while there was no connection issue. I verified this by restarting app containers while keeping the Redis containers up and then there was no UnknownHostException. The reason unknow to me was if initially if there was UnknowHostException why ClusterTopologyRefreshOptions did not work? As per my thinking it should have looked up the hostname again after some duration and would have got the resolution/ip from the consul. But that did not happen
I want to define cxf:rsclient in Java dsl instead of xml based dsl.
I have the following defined in Java dsl.
from("direct:fromChannel")
.split()
.tokenizeXML("APIDataMessage").streaming()
.unmarshal(jaxb)
.convertBodyTo(com.testing.camel.MeasureEvent.class)
.setHeader("Content-Type", constant("application/json"))
.to("cxfrs://bean://toClient");
And I have the following for RSClient
#Bean
public SpringJAXRSClientFactoryBean toClient()
{
SpringJAXRSClientFactoryBean springJAXRSClientFactoryBean = new SpringJAXRSClientFactoryBean();
String measurementEventURL = "http://" + connectorsConfig.getHost() +
":" + connectorsConfig.getPort() + "/api/measurementEvents";
springJAXRSClientFactoryBean.setBeanId("toClient");
springJAXRSClientFactoryBean.setAddress(measurementEventURL);
springJAXRSClientFactoryBean.setServiceClass(com.testing.camel.MeasurementEventEndpoint.class);
springJAXRSClientFactoryBean.setLoggingFeatureEnabled(true);
springJAXRSClientFactoryBean.setSkipFaultLogging(true);
springJAXRSClientFactoryBean.setProvider(jsonProvider());
return springJAXRSClientFactoryBean;
}
And here is my jsonProvider definition:
JacksonJsonProvider jsonProvider()
{
return new JacksonJsonProvider();
}
And following is the stacktrace that I see while calling this route.
