I've been trying to set up a simple WebSocketHandler implementation but I've been running into this error javax.servlet.ServletException: No adapter for handler [turnip.gg.TurnipWebSocketHandler#5fdceca2]: The DispatcherServlet configuration needs to include a HandlerAdapter that supports this handler that I have not been able to solve.
Here's my configuration;
#Configuration
class WebSocket {
#Autowired
#Qualifier("TurnipWebSocket")
private lateinit var handler: WebSocketHandler
#Bean
fun handlerMapping() = SimpleUrlHandlerMapping(mapOf("/socket" to handler), 1)
#Bean
fun handlerAdapter() = WebSocketHandlerAdapter()
}
And here's my simple WebSocketHandler
#Component("TurnipWebSocket")
class TurnipWebSocketHandler : WebSocketHandler {
override fun handle(session: WebSocketSession): Mono<Void> = session.receive()... // Does other stuff with it
}
Thanks in advance!

In RestTemplate I have a custom interceptor which will log some request response details and saves to database.
my custom Interceptor:
import org.springframework.http.HttpRequest;
import org.springframework.http.client.ClientHttpRequestExecution;
import org.springframework.http.client.ClientHttpRequestInterceptor;
#Component
public class LogServices implements ClientHttpRequestInterceptor {
#Override
public ClientHttpResponse intercept(final HttpRequest request, final byte[] body, final ClientHttpRequestExecution execution) throws IOException {
final String uri = request.getURI().toString();
final ClientHttpResponse response = execution.execute(request, body);
//log request response details and save to database
return response;
RestTemplate bean configuration in springboot:
#Bean
public RestTemplate restTemplate(final RestTemplateBuilder restTemplateBuilder) {
return restTemplateBuilder
.setConnectTimeout(Duration.ofMillis(connectTimeout))
.setReadTimeout(Duration.ofMillis(readTimeout))
.build();
Add the interceptor to restTemplate bean:
#Configuration
public class LogInterceptorConfiguration {
#Autowired
public void configureLogger(final RestTemplate restTemplate, final LogServices logServices) {
final var interceptors = restTemplate.getInterceptors();
interceptors.add(logServices);
restTemplate.setInterceptors(interceptors);
}
How can I add this interceptor to FeignClient?
In application.yml:
feign:
client:
config:
default:
connectTimeout: 5000
readTimeout: 5000
request-interceptors[0]: com.api.restclient.InterceptorOne
request-interceptors[1]: com.api.log.LogServices
InterceptorOne which adds a header to every request in feign client:
#Configuration
public class InterceptorOne implements RequestInterceptor {
#Override
public void apply(RequestTemplate requestTemplate) {
requestTemplate.header("some-header", "value");
}
But I cannot add the LogServices interceptor since it does not work due to the error cannot be cast to class feign.RequestInterceptor
My guess is that the interceptor I am trying to add is a generic interceptor and not specifically request interceptor. So I want to know how do I add a generic interceptor to FeignClient similar to RestTemplate
You can add multiple interceptors as follows
feign:
client:
config:
feignName:
connectTimeout: 5000
readTimeout: 5000
loggerLevel: full
errorDecoder: com.example.SimpleErrorDecoder
retryer: com.example.SimpleRetryer
requestInterceptors:
- com.example.InterceptorOne
- com.example.LogServices
decode404: false
encoder: com.example.SimpleEncoder
decoder: com.example.SimpleDecoder
contract: com.example.SimpleContract
When I use org.springframework.boot:spring-boot-starter-web, I can remove Whitelabel error page and instead of it to show my message, when to link not found resource:
application.yml
server:
error:
whitelabel:
enabled: false
spring:
mvc:
throw-exception-if-no-handler-found: true
resources:
add-mappings: false
NotFoundResource.class
#RestControllerAdvice
class NotFoundResource {
#ExceptionHandler(NoHandlerFoundException.class)
public String handleNotFoundResource() {
return "Requested resource wasn't found on the server"
}
}
How do I do it with webflux? In weblux doesn't contain NoHandlerFoundException.class.
You can create your own ErrorWebExceptionHandler class for this requirement. Spring boot documentation gives insight on this.
[Quoted from documentation]
To change the error handling behavior, you can implement
ErrorWebExceptionHandler and register a bean definition of that type.
Because a WebExceptionHandler is quite low-level, Spring Boot also
provides a convenient AbstractErrorWebExceptionHandler to let you
handle errors in a WebFlux functional way, as shown in the following
example
For a more complete picture, you can also subclass
DefaultErrorWebExceptionHandler directly and override specific
methods.
You can put some breakpoints on DefaultErrorWebExceptionHandler class and check how it works to render error response. Then based on your project requirement you can customize it for your need.
Here is a very simple thing I tried out.
CustomErrorWebExceptionHandler class:
public class CustomErrorWebExceptionHandler extends AbstractErrorWebExceptionHandler {
public CustomErrorWebExceptionHandler(
ErrorAttributes errorAttributes,
ResourceProperties resourceProperties,
ApplicationContext applicationContext) {
super(errorAttributes, resourceProperties, applicationContext);
}
#Override
protected RouterFunction<ServerResponse> getRoutingFunction(ErrorAttributes errorAttributes) {
return route(all(), this::renderErrorResponse);
}
private Mono<ServerResponse> renderErrorResponse(ServerRequest serverRequest) {
Throwable throwable = (Throwable) serverRequest
.attribute("org.springframework.boot.web.reactive.error.DefaultErrorAttributes.ERROR")
.orElseThrow(
() -> new IllegalStateException("Missing exception attribute in ServerWebExchange"));
if (throwable.getMessage().equals("404 NOT_FOUND \"No matching handler\"")) {
return ServerResponse.status(HttpStatus.BAD_REQUEST).contentType(MediaType.APPLICATION_JSON)
.body(Mono.just("Requested resource wasn't found on the server"), String.class);
} else {
return ServerResponse.status(HttpStatus.BAD_REQUEST).contentType(MediaType.APPLICATION_JSON)
.body(Mono.just("Some Error happened"), String.class);
}
}
}
Create a bean from that class:
#Configuration(proxyBeanMethods = false)
#ConditionalOnWebApplication(type = ConditionalOnWebApplication.Type.REACTIVE)
#ConditionalOnClass(WebFluxConfigurer.class)
#AutoConfigureBefore(ErrorWebFluxAutoConfiguration.class)
public class Beans {
#Bean
#Order(-1)
public CustomErrorWebExceptionHandler modelMapper(ErrorAttributes errorAttributes,
ResourceProperties resourceProperties,
ApplicationContext applicationContext, ServerCodecConfigurer serverCodecConfigurer,
ObjectProvider<ViewResolver> viewResolvers) {
CustomErrorWebExceptionHandler customErrorWebExceptionHandler = new CustomErrorWebExceptionHandler(
errorAttributes, resourceProperties,
applicationContext);
customErrorWebExceptionHandler
.setViewResolvers(viewResolvers.orderedStream().collect(Collectors.toList()));
customErrorWebExceptionHandler.setMessageWriters(serverCodecConfigurer.getWriters());
customErrorWebExceptionHandler.setMessageReaders(serverCodecConfigurer.getReaders());
return customErrorWebExceptionHandler;
}
}
application.properties:
server.error.whitelabel.enabled=false
spring.mvc.throw-exception-if-no-handler-found=true
spring.resources.add-mappings=false

I am calling another microservice once my current microservice is up and ready using feign client in my current microservice built using Jhipster.
So my Feign Interface is
package com.persistent.integration.client;
import java.util.List;
import org.springframework.data.domain.Pageable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import com.persistent.integration.service.dto.DataPipelineDTO;
#AuthorizedFeignClient(name = "Integrationconfiguration")
public interface DataPipelinesResourceFeign {
#RequestMapping(value = "/api/data-pipelines", method = RequestMethod.GET)
List<DataPipelineDTO> getAllDataPipelines(#RequestParam(value = "pageable") Pageable pageable );
}
}
And I have implemented ApplicationRunner where I have called feign client method.
#Component
public class ApplicationInitializer implements ApplicationRunner {
#Autowired
private DataPipelinesResourceFeign dataPipelinesResourceFeign;
#Autowired
private ActiveMQListener activeMqListener;
#Override
public void run(ApplicationArguments args) throws Exception {
// TODO Auto-generated method stub
Pageable pageable = PageRequest.of(0, 20);
try {
List <DataPipelineDTO> allStartedDataPipeLines = dataPipelinesResourceFeign.getAllDataPipelines(pageable); //.stream().filter(p->p.getState().equals(State.STARTED)).collect(Collectors.toList());
allStartedDataPipeLines.forEach(datapipe ->
{
try {
activeMqListener.consume(datapipe);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
});
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
But after running this, it gives below exception at dataPipelinesResourceFeign.getAllDataPipelines :

many suggestions on internet were to add listerner RequestContextListener. But problem persisted even if I added listener in webConfigurer.java in onStartup method.
{
servletContext.addListener(RequestContextListener.class);
}
But of no use.
Any leads would be appreciated.
I found a workaround for this. I don't know why TokenRelayRequestIntercepton isn't working but you can use your own RequestInterceptor based on Spring's SecurityContext.
First, define a RequestInterceptor :
public class MyRequestInterceptor implements RequestInterceptor {
public static final String AUTHORIZATION = "Authorization";
public static final String BEARER = "Bearer";
public MyRequestInterceptor() {
super();
}
#Override
public void apply(RequestTemplate template) {
// demander un token à keycloak et le joindre à la request
Optional<String> header = getAuthorizationHeader();
if (header.isPresent()) {
template.header(AUTHORIZATION, header.get());
}
}
public static Optional<String> getAuthorizationHeader() {
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
if (authentication != null && authentication.getDetails() != null && authentication.getDetails() instanceof OAuth2AuthenticationDetails) {
OAuth2AuthenticationDetails oAuth2AuthenticationDetails =
(OAuth2AuthenticationDetails) authentication.getDetails();
return Optional.of(String.format("%s %s", oAuth2AuthenticationDetails.getTokenType(),
oAuth2AuthenticationDetails.getTokenValue()));
} else {
return Optional.empty();
}
}
}
and then, declare a config class for your feign client using your RequestInterceptor, it should contains something like this :
#Bean(name = "myRequestInterceptor")
public RequestInterceptor getMyRequestInterceptor() throws IOException {
return new MyRequestInterceptor();
}
Your Feign client shoud look like this:
#FeignClient(name = "SERVICE_NAME", configuration = MyFeignConfiguration.class)
public interface MyRestClient {
I had the same issue with Feign Client running on startup using ApplicationRunner and I came up with following solution.
I defined my FeignClientsConfiguration with OAuth2FeignRequestInterceptor, which accepts predefined bean DefaultOAuth2ClientContext and OAuth2 configuration OAuth2ProtectedResourceDetails:
#Configuration
public class MyConfig extends FeignClientsConfiguration {
#Bean
public RequestInterceptor oauth2FeignRequestInterceptor( DefaultOAuth2ClientContext oAuth2ClientContext, MyOauth2Properties properties) {
return new OAuth2FeignRequestInterceptor(oAuth2ClientContext, resourceDetails(properties));
}
#Bean
public DefaultOAuth2ClientContext oAuth2ClientContext() {
return new DefaultOAuth2ClientContext();
}
private OAuth2ProtectedResourceDetails resourceDetails(MyOauth2Properties oauth2Properties) {
ResourceOwnerPasswordResourceDetails resourceDetails = new ResourceOwnerPasswordResourceDetails();
resourceDetails.setAccessTokenUri(oauth2Properties.getAccessTokenUri());
resourceDetails.setUsername(oauth2Properties.getUsername());
resourceDetails.setPassword(oauth2Properties.getPassword());
resourceDetails.setClientId(oauth2Properties.getClientId());
return resourceDetails;
}
}
Your feign client will look something like this:
#FeignClient(url = "http://localhost:8080/api/v1")
public interface FeignClient {
}
After all this, calling FeignClient from ApplicationRunner.run() works fine.
Spring Boot 2.2.6
I have mixins configured in my objectmapperbuilder config, using the regular spring web controller, the data outputted according to the mixins.
However using webflux, a controller with a method returning a Flow or Mono have the data serialized like if the objectmapper a default one.
How to get webflux to enforce an objectmapper configuration to be used ?
sample config:
#Bean
JavaTimeModule javatimeModule(){
return new JavaTimeModule();
}
#Bean
Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer(){
return jacksonObjectMapperBuilder -> jacksonObjectMapperBuilder.featuresToEnable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS)
.mixIn(MyClass.class, MyClassMixin.class);
}
I actually found my solution by stepping through the init code:
#Configuration
public class Config {
#Bean
JavaTimeModule javatimeModule(){
return new JavaTimeModule();
}
#Bean
Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer(){
return jacksonObjectMapperBuilder -> jacksonObjectMapperBuilder.featuresToEnable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS)
.mixIn(MyClass.class, MyClassMixin.class);
}
#Bean
Jackson2JsonEncoder jackson2JsonEncoder(ObjectMapper mapper){
return new Jackson2JsonEncoder(mapper);
}
#Bean
Jackson2JsonDecoder jackson2JsonDecoder(ObjectMapper mapper){
return new Jackson2JsonDecoder(mapper);
}
#Bean
WebFluxConfigurer webFluxConfigurer(Jackson2JsonEncoder encoder, Jackson2JsonDecoder decoder){
return new WebFluxConfigurer() {
#Override
public void configureHttpMessageCodecs(ServerCodecConfigurer configurer) {
configurer.defaultCodecs().jackson2JsonEncoder(encoder);
configurer.defaultCodecs().jackson2JsonDecoder(decoder);
}
};
}
}
I translated the solution of #Alberto Galiana to Java and injected the configured Objectmapper for convenience, so you avoid having to do multiple configurations:
#Configuration
#RequiredArgsConstructor
public class WebFluxConfig implements WebFluxConfigurer {
private final ObjectMapper objectMapper;
public void configureHttpMessageCodecs(ServerCodecConfigurer configurer) {
configurer.defaultCodecs().jackson2JsonEncoder(
new Jackson2JsonEncoder(objectMapper)
);
configurer.defaultCodecs().jackson2JsonDecoder(
new Jackson2JsonDecoder(objectMapper)
);
}
}
Just implement WebFluxConfigurer and override method configureHttpMessageCodecs
Sample code for Spring Boot 2 + Kotlin
#Configuration
#EnableWebFlux
class WebConfiguration : WebFluxConfigurer {
override fun configureHttpMessageCodecs(configurer: ServerCodecConfigurer) {
configurer.defaultCodecs().jackson2JsonEncoder(Jackson2JsonEncoder(ObjectMapper()
.setSerializationInclusion(JsonInclude.Include.NON_EMPTY)))
configurer.defaultCodecs().jackson2JsonDecoder(Jackson2JsonDecoder(ObjectMapper()
.enable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES)))
}
}
Make sure all your data classes to be encoded/decoded have all its properties annotated with #JsonProperty even if property name is equal in class and json data
data class MyClass(
#NotNull
#JsonProperty("id")
val id: String,
#NotNull
#JsonProperty("my_name")
val name: String)
In my case, I was trying to use a customized ObjectMapper while inheriting all of the behavior from my app's default WebClient.
I found that I had to use WebClient.Builder.codecs. When I used WebClient.Builder.exchangeStrategies, the provided overrides were ignored. Not sure if this behavior is something specific to using WebClient.mutate, but this is the only solution I found that worked.
WebClient customizedWebClient = webClient.mutate()
.codecs(clientCodecConfigurer ->
clientCodecConfigurer.defaultCodecs()
.jackson2JsonDecoder(new Jackson2JsonDecoder(customObjectMapper)))
.build();
I have tried all the different solutions (#Primary #Bean for ObjectMapper, configureHttpMessageCodecs(), etc.). What worked for me at the end was specifying a MIME type. Here's an example:
#Configuration
class WebConfig: WebFluxConfigurer {
override fun configureHttpMessageCodecs(configurer: ServerCodecConfigurer) {
val encoder = Jackson2JsonEncoder(objectMapper, MimeTypeUtils.APPLICATION_JSON)
val decoder = Jackson2JsonDecoder(objectMapper, MimeTypeUtils.APPLICATION_JSON)
configurer.defaultCodecs().jackson2JsonEncoder(encoder)
configurer.defaultCodecs().jackson2JsonDecoder(decoder)
}
}
I want to define RestTemplate as an application bean using #Bean annotation in my configuration class in a spring boot application.
I am calling 4 rest services in different places in my application flow. Currently I am creating RestTemplate every time every request. Is there a way I can define that as application bean using #Bean and inject that using #Autowired?
Main reason for this question is I can able to define RestTemplate using #Bean but when I inject it with #Autowired I am loosing all defined interceptors (Interceptors are not getting called.)
Configuration Class
#Bean(name = "appRestClient")
public RestTemplate getRestClient() {
RestTemplate restClient = new RestTemplate(
new BufferingClientHttpRequestFactory(new SimpleClientHttpRequestFactory()));
List<ClientHttpRequestInterceptor> interceptors = new ArrayList<ClientHttpRequestInterceptor>();
interceptors.add(new RestServiceLoggingInterceptor());
restClient.setInterceptors(interceptors);
return restClient;
}
Service Class
public class MyServiceClass {
#Autowired
private RestTemplate appRestClient;
public String callRestService() {
// create uri, method response objects
String restResp = appRestClient.getForObject(uri, method, response);
// do something with the restResp
// return String
}
}
It seems my Interceptors are not getting called at all with this configuration. But RestTemplate is able to make a call to the REST service and get a response.
Answer for Spring boot 2.*.* version.
I am using Spring boot 2.1.2.RELEASE and I also added RestTemplate in my project in a class where mail method exists.
#Bean
public RestTemplate restTemplate(RestTemplateBuilder builder) {
return builder.setConnectTimeout(Duration.ofMillis(300000))
.setReadTimeout(Duration.ofMillis(300000)).build();
}
and Used in my service or other classes like this
#Autowired
RestTemplate res;
and in methods
HttpEntity<String> entity = new HttpEntity<>(str, headers);
return res.exchange(url, HttpMethod.POST, entity, Object.class);
Judging form the name of the interceptor, I'm guessing you're doing some logging in it? You could of missed logging level configuration. I created a small application to check weather your configuration works, using 1.3.6.RELEASE version.
In this class I define the RestTemplate bean and the interceptor with logging.
package com.example;
// imports...
#SpringBootApplication
public class TestApplication {
private static final Logger LOGGER = LoggerFactory.getLogger(TestApplication.class);
public static void main(String[] args) {
SpringApplication.run(TestApplication.class, args);
}
#Bean(name = "appRestClient")
public RestTemplate getRestClient() {
RestTemplate restClient = new RestTemplate(
new BufferingClientHttpRequestFactory(new SimpleClientHttpRequestFactory()));
// Add one interceptor like in your example, except using anonymous class.
restClient.setInterceptors(Collections.singletonList((request, body, execution) -> {
LOGGER.debug("Intercepting...");
return execution.execute(request, body);
}));
return restClient;
}
}
For logging to work, I also have to set the correct debug level in application.properties.
logging.level.com.example=DEBUG
Then I create a service where I inject this RestTemplate.
#Service
public class SomeService {
private final RestTemplate appRestClient;
#Autowired
public SomeService(#Qualifier("appRestClient") RestTemplate appRestClient) {
this.appRestClient = appRestClient;
}
public String callRestService() {
return appRestClient.getForObject("http://localhost:8080", String.class);
}
}
And also an endpoint to test this out.
#RestController
public class SomeController {
private final SomeService service;
#Autowired
public SomeController(SomeService service) {
this.service = service;
}
#RequestMapping(value = "/", method = RequestMethod.GET)
public String testEndpoint() {
return "hello!";
}
#RequestMapping(value = "/test", method = RequestMethod.GET)
public String test() {
return service.callRestService();
}
}
By performing a GET request to http://localhost:8080/test I should expect to get the String hello! getting printed (the service makes a call to http://localhost:8080 which returns hello! and sends this back to me). The interceptor with logger also prints out Intercepting... in the console.
Edd's solution won't work if you're using Spring Boot 1.4.0 or later. You will have to use RestTemplateBuilder to get this working. Here is the example
#Bean(name="simpleRestTemplate")
#Primary
public RestTemplate restTemplate(RestTemplateBuilder restTemplateBuilder){
RestTemplate template = restTemplateBuilder.requestFactory(new BufferingClientHttpRequestFactory(new SimpleClientHttpRequestFactory()))
.interceptors(logRestRequestInterceptor) //This is your custom interceptor bean
.messageConverters(new MappingJackson2HttpMessageConverter())
.build();
return template;
}
Now you can autowire the bean into your service class
#Autowired
#Qualifier("simpleRestTemplate")
private RestTemplate simpleRestTemplate;
Hope this helps
