We have implemented a micro service architecture having Eureka discovery server,spring cloud API gate way,Spring cloud config server and a microservice rest API.
These are working very well now.The next step am planed to enable the spring cloud load balancer.
I prefer the load balancer inside the gate way.When i run the while applications,all services are registered in the eureka server.Refer the screen short
Gate way routing implemented like below
#Configuration
public class RequestRouter {
#Bean
public RouteLocator gatewayRoutes(RouteLocatorBuilder builder) {
return builder.routes().route(r -> r.path("/service-one/**")
.uri("lb://MICROSERVICE-ONE/")).build();
}
}
On the routing URI i refer lb with application name which shown in the eureka server.
When i send a request to the microservice rest API .The gateway log says
2022-07-01 23:11:38.690 WARN 36552 --- [ctor-http-nio-3] o.s.c.l.core.RoundRobinLoadBalancer : No servers available for service: MICROSERVICE-ONE

what was the mistake i made here.
suggest a better solution.Spend a lot of time on the top this issue, could not resolve it .
Thanks in advance

I am trying out a spring boot app using web-flux, and r2dbc for PostgreSQL, initially I could do few POST, GET, PUT, DELETE actions. However, when I tried to link customer table with subscription table, errors started to show up.
I am pasting these entity classes below here

private long customerId;
private String customerName;
private String customerEmail;
private String customerPhone;
#OneToMany(fetch = FetchType.EAGER, mappedBy = "customer", cascade = CascadeType.ALL)
#JsonIgnoreProperties("customer")
private List<Subscription> subscriptionList = new ArrayList<>();
}

I referred internet to resolve this problem, but didn't come across to anything helpful. Any help would be appreciable.
You can choose to delete all the records associated to the customer by running the command below on your DB. On your query console the command below.
NOTE: If this works if you intend to delete all records associated to that customer.
alter table subscriptions
add constraint subscriptions_subscription_id_fk
foreign key (customer_id) references customers (id) on delete cascade;
This is equivalent to
#ManyToOne(mappedBy = "customer", cascade = CascadeType.ALL)
When using JPA
I am using Spring Boot 2.2.4 with spring-boot-starter-webflux, spring-boot-starter-security and spring-security-oauth2-client.
With the reactive WebClient I want to call Auth0's management API using OAuth 2.0 client credentials to get some user information.
I have followed Baeldung's Spring WebClient and OAuth2 Support tutorial. My application.properties looks like this:
spring.security.oauth2.client.registration.auth0.authorization-grant-type=client_credentials
spring.security.oauth2.client.registration.auth0.client-id=XXX
spring.security.oauth2.client.registration.auth0.client-secret=YYY
spring.security.oauth2.client.provider.auth0.token-uri=https://ZZZ.eu.auth0.com/oauth/token
My Spring #Configuration like this:
#Configuration
#RequiredArgsConstructor
class Auth0Configuration {
#Value("${auth0.api.base-url}")
private final String auth0ApiBaseUrl;
#Bean
WebClient auth0WebClient(ReactiveClientRegistrationRepository reactiveClientRegistrationRepository) {
ServerOAuth2AuthorizedClientExchangeFilterFunction oauth =
new ServerOAuth2AuthorizedClientExchangeFilterFunction(
reactiveClientRegistrationRepository,
new UnAuthenticatedServerOAuth2AuthorizedClientRepository());
oauth.setDefaultClientRegistrationId("auth0");
return WebClient.builder()
.filter(oauth)
.baseUrl(auth0ApiBaseUrl)
.build();
}
}
But when I make the first call with the WebClient, this error occurs:
2020-02-12 20:18:11.098 ERROR 1945 --- [ctor-http-nio-3] a.w.r.e.AbstractErrorWebExceptionHandler : [f0218135] 500 Server Error for HTTP GET "/oauth2/authorization/auth0"

When following the stack trace I see that the property redirectUriTemplate in the ClientRegistration is null. But since I am using client credentials a redirect URI shouldn't be needed at all.
Is there an error in my configuration? How can I make WebClient work with the client credentials flow?
The application is working now with this configuration:
#Configuration
#RequiredArgsConstructor
#Slf4j
class Auth0Configuration {
// some properties
#Bean
WebClient auth0WebClient(ReactiveOAuth2AuthorizedClientManager authorizedClientManager) {
var exchangeFilterFunction = new ServerOAuth2AuthorizedClientExchangeFilterFunction(authorizedClientManager);
exchangeFilterFunction.setDefaultClientRegistrationId(AUTH_0_CLIENT_REGISTRATION_ID);
return WebClient.builder()
.baseUrl(auth0ApiBaseUrl)
.filter(exchangeFilterFunction)
.defaultHeader(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE)
.build();
}
#Bean
public ReactiveClientRegistrationRepository reactiveClientRegistrationRepository() {
return new InMemoryReactiveClientRegistrationRepository(
ClientRegistration.withRegistrationId(AUTH_0_CLIENT_REGISTRATION_ID)
.authorizationGrantType(AuthorizationGrantType.CLIENT_CREDENTIALS)
.tokenUri(auth0TokenUri)
.clientAuthenticationMethod(ClientAuthenticationMethod.POST)
.clientId(auth0ClientId)
.clientSecret(auth0ClientSecret)
.scope()
.build()
);
}
#Bean
public ReactiveOAuth2AuthorizedClientManager reactiveOAuth2AuthorizedClientManager(ReactiveClientRegistrationRepository clientRegistrationRepository) {
DefaultReactiveOAuth2AuthorizedClientManager authorizedClientManager =
new DefaultReactiveOAuth2AuthorizedClientManager(clientRegistrationRepository, new UnAuthenticatedServerOAuth2AuthorizedClientRepository());
authorizedClientManager.setAuthorizedClientProvider(ReactiveOAuth2AuthorizedClientProviderBuilder.builder()
.clientCredentials(clientCredentialsGrantBuilder -> {
WebClientReactiveClientCredentialsTokenResponseClient accessTokenResponseClient = new WebClientReactiveClientCredentialsTokenResponseClient();
accessTokenResponseClient.setWebClient(WebClient.builder()
.filter((request, next) -> {
FormInserter<String> body = (FormInserter<String>) request.body();
body.with("audience", auth0Audience);
return next.exchange(request);
})
.build());
clientCredentialsGrantBuilder.accessTokenResponseClient(accessTokenResponseClient);
}
)
.build()
);
return authorizedClientManager;
}
}
I am trying to run the sonar gradle plugin and after running the tests I get the following:

EDIT:Turns out the cause is the Sonar Surefire library, more specifically the fact that it is not designed to handle unbalanced parentheses in test class names and I accidentally left unbalanced parentheses in one of my cucumber scenario names
Summarizing the solution from the comments, this problem is caused by unbalanced parentheses in scenario names. It is best to avoid parentheses in feature and scenario names.
In my specific case, I had a Feature called Feedback (bounce and confirmation), and this caused cucumber to generate per scenario reports with the name ).Email successfully sent( instead of the usual Feedback (bounce and confirmation).Email successfully sent. And apparently, the sonarqube plugin doesn't like that.
Changing the feature name to Bounce and confirmation feedback solved the issue.
