Xilai Dai commented on CAMEL-12252:
-----------------------------------

To fix it, the address has to be set on the JAXRSClientFactoryBean object of 
the ClientFactoryBeanCache of the CxfRsProducer, then even the Endpoint is 
Singleton, the Address still can be set dynamiclly.

> Dynamic setting the DESTINATION_OVERRIDE_URL doesn't work on CXFRS producer

>                 URL: https://issues.apache.org/jira/browse/CAMEL-12252
>             Project: Camel
>          Issue Type: Bug
>          Components: camel-cxfrs
>    Affects Versions: 2.17.0, 2.18.5, 2.19.4, 2.20.2
>         Environment: Java 8
>            Reporter: Xilai Dai
>            Priority: Major

> Given the sample MyProcessor, setting the DESTINATION_OVERRIDE_URL 
> dynamically during the invoke:
> {code}
> public void process(Exchange exchange) throws Exception {
>     String env = (String)exchange.getIn().getHeader("Environnement");
>     if (env.equalsIgnoreCase("DEV")) {
>         exchange.getIn().setHeader(exchange.DESTINATION_OVERRIDE_URL,
>             "http://esbdev11.local:8080/server1/metaServlet";);
>     } else {
>         exchange.getIn().setHeader(exchange.DESTINATION_OVERRIDE_URL,
>             "http://esblab11.local:8080/server2/metaServlet";);
>     }
> }
> {code}
> Given the sample Route:
> {code}
>         from("cxfrs:bean:MyREST")
>         .process(new HeaderProcessor())
>         .setHeader("Environnement")
>         .simple("${header.http_query[env][0]}")
>         .process(new MyProcessor())
>         .setHeader(org.apache.camel.Exchange.HTTP_METHOD, constant("GET"))
>         .setHeader(org.apache.camel.Exchange.ACCEPT_CONTENT_TYPE, 
> constant("*/*"))
>         .setHeader(org.apache.camel.Exchange.HTTP_PATH, constant("/"))
>         .to("cxfrs:bean:restClient?maxClientCacheSize=5");
> {code}
> Send request to cxfrs:bean:MyREST with different http header "dev", then the 
> cxfrs:bean:restClient always make call to the last setting Address.
> (Only it works as expected when setting maxClientCacheSize=0 on the 
> cxfrs:bean:restClient)
> There is no this issue on Camel 2.16.x, but start problem from Camel 2.17.x 
> and later versions. Investigations show that the CxfRsEndpoint becoming 
> Singleton after CAMEL-9628, that explain why the last Address setting always 
> applied.
