Description

Hello,

we have defined a Spring based custom instance of AsyncHttpClient. This instance should be used by adding the property

camel.component.ahc-ws.client = asyncHttpClientTimeseriesImpl

to yaml file.

The implementation looks like this:

 

@Component
@RequiredArgsConstructor
public class AsyncHttpClientTimeseriesImpl extends DefaultAsyncHttpClient {
/* ... custom members ... */
@Override
 @SuppressWarnings("ConstantConditions")
 public synchronized BoundRequestBuilder prepareGet(String url) {
  /* a token is requested to be added to the httpHeaders */
}

 

When using the ahc-wss endpoint in a route, the custom client is never used. Instead a DefaultAsyncHttpClient is instanciated and will fail to connect, due to missing httpHeader containing the valid token.

Example of the route:

<route id="distributorCloudRoute">
  <from uri="seda:distributorEntryPoint?multipleConsumers=true"/>
  <to uri="ahc-wss:<url_of_externalHost>"/>
</route>

 

used dependencies from pom.xml:

<parent>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-dependencies</artifactId>
  <version>2.2.0.RELEASE</version>
</parent>
<apache-camel.version>3.4.4</apache-camel.version>
<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-spring-boot-starter</artifactId>
  <version>${apache-camel.version}</version>
</dependency>
<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-ahc-ws-starter</artifactId>
  <version>${apache-camel.version}</version>
</dependency>

 

In the former version that was used - Camel 3.1.0 - the error didn't occur.

It would be nice if you can confirm the wrong behaviour of AHC-WS component and give an possible version containing the fix.

Best regards
