Describe the bug
I'm using MP Rest Client to call another Rest Service from my service implementation and want to overwrite some header attributes by using @ClientsHeadersFactory, but when I using @Inject to use another CDI Beans then a NullpointerException is raised.
With Micro Profile Rest Client 1.4 there is the possibility to use '@Inject' if your implementation is managed by CDI. This allows you to inject secrets for example or any other CDI bean to calculate a header value.
Expected behavior injected ConfigProperty is available and not null
Actual behavior NullpointerException is occur in update method of implementation of ClientHeadersFactory.
To Reproduce Steps to reproduce the behavior:
- Create a implementation class of ClientHeadersFactory and override update method
@ApplicationScoped
public class MyClientHeadersFactory implements ClientHeadersFactory {
@Inject
@ConfigProperty(name = "secrets.value")
private String secretValue;
@Override
public MultivaluedMap<String, String> update(MultivaluedMap<String, String> incomingHeaders, MultivaluedMap<String, String> clientOutgoingHeaders) {
System.out.println("--- Incoming headers of the JAX-RS environment");
incomingHeaders.forEach((k, v) -> System.out.println(k + ":" + v));
System.out.println("--- Specified outgoing headers of the Rest Client");
clientOutgoingHeaders.forEach((k, v) -> System.out.println(k + ":" + v));
MultivaluedMap<String, String> resultHeader = new MultivaluedHashMap();
resultHeader.putAll(incomingHeaders);
resultHeader.putAll(clientOutgoingHeaders);
//here is the NullpointerException raised
resultHeader.add("X-Secret-Header", secretValue);
System.out.println("--- Header of the Rest Client after merging");
resultHeader.forEach((k, v) -> System.out.println(k + ":" + v));
return resultHeader;
}
}
- Register your implemented ClientHeadersFactory in your Rest Client interface by using
@RegisterClientHeaders()
@RegisterRestClient(configKey = "remote-restservice")
@RegisterClientHeaders(MyClientHeadersFactory.class)
public interface RemoteRestService
{
@POST
@Path("/doSomeStuff")
@Consumes({ "application/json" })
@Produces({ "application/json" })
Response createStuff( @Valid Stuff stuff);
}
Configuration
# Add your application.properties here, if applicable.
remote-restservice/mp-rest/url=http://localhost:9090/service
