in AuthenticationResponseParser.parse(new URI(fullUrl), params);
where params is
Map<String, List<String>>
and is created as
for (String key : httpRequest.getParameterMap().keySet()) {
params.put(key, Collections.singletonList(httpRequest.getParameterMap().get(key)[0]));
}
throws exception
Error: class java.util.Collections$SingletonList cannot be cast to class java.lang.String (java.util.Collections$SingletonList and java.lang.String are in module java.base of loader 'bootstrap')
What could be going wrong?
I am using MSALJ maven dependency com.microsoft.azure, msal4j, 1.13.2
Tried to pass String as params but it is expecting List of strings
Using Spring 2.7.0 to create an API gateway, that was working fine until I tried to replace the RestTemplate with OpenFeign.
Here is the relevant build.gradle contents:

My FeignClient:

when I try to start the application now I get:

Description:
A component required a bean of type 'org.springframework.boot.autoconfigure.http.HttpMessageConverters' that could not be found.
Action:
Consider defining a bean of type 'org.springframework.boot.autoconfigure.http.HttpMessageConverters' in your configuration.
But none of the online examples seem to show the need for adding custom HttpMessageConverters since they are included in spring-web and spring-boot-starter-webflux
UPDATE -
this appears to be related to #Autowired. I put both my service and feign service in a regular class and it starts up fine. But when I autowire those two services, I get this error again.
After upgrading to micronaut 3.x and replacing the annotation Javax.inject to Jakarta.inject. #Named is unable resolve the property.
import io.micronaut.context.annotation.Bean
import io.micronaut.context.annotation.Factory
import io.micronaut.context.annotation.Requires
import java.util.concurrent.ExecutorService
import jakarta.inject.Named
import kotlin.coroutines.CoroutineContext
#Factory
open class ExecutorServiceCoroutineContextFactory {
#Bean
#Requires(missingBeans = [CoroutineContext::class])
fun executorServiceCoroutineContext(#Named("\${coroutines.executor}")executorService: ExecutorService): CoroutineContext {
return ExecutorServiceCoroutineDispatcher(executorService)
}
}
application.yml
coroutines:
executor: coroutines
The resulting error
Message: No bean of type [java.util.concurrent.ExecutorService] exists for the given qualifier: #Named('${coroutines.executor}'). Make sure the bean is not disabled by bean requirements (enable trace logging for 'io.micronaut.context.condition' to check) and if the bean is enabled then ensure the class is declared a bean and annotation processing is enabled (for Java and Kotlin the 'micronaut-inject-java' dependency should be configured as an annotation processor).
Path Taken: new Controller(Client client,CoroutineContext coroutineContext) --> new Controller(Client client,[CoroutineContext coroutineContext]) --> CoroutineContext.executorServiceCoroutineContext([ExecutorService executorService],String name)
io.micronaut.context.exceptions.DependencyInjectionException: Failed to inject value for parameter [executorService] of method [executorServiceCoroutineContext] of class: kotlin.coroutines.CoroutineContext
Hardcoding the value "coroutines" does work but wondering why the code can't resolve it.
I am trying to implement a custom annotation (meta annotation) for #Controller as follows:
#MustBeDocumented
#Retention(AnnotationRetention.RUNTIME)
#Target(AnnotationTarget.CLASS)
#Secured(SecurityRule.IS_AUTHENTICATED)
#Controller
annotation class CustomController(
#get:AliasFor(annotation = Controller::class)
val value: String
)
//Usage:
#CustomController("/demo-api")
class ChangeController(private val changeGroupApi: ChangeGroupApi) {
//...
}
However, Micronaut behaves as if the controller class isn't even annotated at all. See related log, it's the same with that when the class isn't annotated.

Any ideas to make it work?
I have a webflux project and I am adding apache geode. In my build.gradle I have:
implementation 'org.springframework.data:spring-data-geode:2.2.4.RELEASE'
implementation 'org.springframework.boot:spring-boot-starter-webflux:2.2.4.RELEASE'
Once adding the spring-data-geode implementation the application crashes with:

The trouble is, if I add
spring.main.web-application-type=none or spring.main.web-application-type=reactive to my application.properties then that interferes with the #ClientCacheApplication(name = "Web", locators = #Locator(host="1.2.3.4", port=10334), logLevel = "debug", subscriptionEnabled = true) annotation and the application does not connect to the geode locator, nor then run the #EnableClusterDefinedRegions which causes problems defining simple regions that I want to pick up from the server.
UPDATE To add spring-boot-starter-web to build.gradle and make the spring boot application type NONE as below appears to fix the instant problem, but...
SpringApplication app = new SpringApplication(Web.class);
app.setWebApplicationType(WebApplicationType.NONE);
SpringApplication.run(Web.class, args);
... but then the webflux mapping cannot find the #Bean websocket handler:
2020-01-28T16:54:26,236 DEBUG [http-nio-8082-exec-2] org.sprin.web.servl.handl.AbstractHandlerMapping 412 getHandler: Mapped to ResourceHttpRequestHandler ["classpath:/META-INF/resources/", "classpath:/resources/", "classpath:/static/", "classpath:/public/", "/"]

and this causes the website to error:
The console log says
WebSocket connection to 'ws://localhost:8082/ws/data' failed: Error during WebSocket handshake: Unexpected response code: 404
The problems with regions was because the classes using the regions defined by #EnableClusterDefinedRegions were (a) instantiated by new command rather than Spring #Autowired; and (b) in another package not seen by the Spring Boot #ComponentScan. Once these were fixed then the regions were auto-defined and handled using #Resource annotation.
#Resource(name = "Example") private Region<Object, Object> example
Also the main program was given
SpringApplication app = new SpringApplication(Web.class);
app.setWebApplicationType(WebApplicationType.REACTIVE);
SpringApplication.run(Web.class, args);
The other problem was fixed by getting the correct dependencies in the build.gradle and then annotating endpoints for rSocket / webSocket with:
#MessageMapping(value = "helloWorld")
public Flux<String> getFluxSocket() {
log.traceEntry();
log.info("In hello world");
return Flux.just("{\"Hello\":\"World\"}");
}
or
#GetMapping(value = "/helloWorld", produces = MediaType.TEXT_EVENT_STREAM_VALUE)
public Flux<String> getRestSocket() {
log.traceEntry();
return Flux.just("Hello World");
}
for HTTP endpoints.
