use of org.springframework.messaging.handler.annotation.support.PayloadArgumentResolver in project spring-cloud-stream by spring-cloud.

the class AbstractBinderTests method buildStreamListener.

    InvocableHandlerMethod method = new InvocableHandlerMethod(this, m);
    HandlerMethodArgumentResolverComposite resolver = new HandlerMethodArgumentResolverComposite();
    CompositeMessageConverterFactory factory = new CompositeMessageConverterFactory();
    resolver.addResolver(new PayloadArgumentResolver(factory.getMessageConverterForAllRegistered()));
    method.setMessageMethodArgumentResolvers(resolver);
    Constructor<?> c = ReflectionUtils.accessibleConstructor(StreamListenerMessageHandler.class, InvocableHandlerMethod.class, boolean.class, String[].class);
    StreamListenerMessageHandler handler = (StreamListenerMessageHandler) c.newInstance(method, false, new String[] {});
