Spring Cloud Stream @SendTo Annotation not working

Question

I\'m using Spring Cloud Stream with Spring Boot. My application is very simple:

ExampleService.class:

@EnableBinding(Processor1.class)
@Service
publi         


        

Answer 1

What leads you to believe that @SendTo on its own is supported? @SendTo is a secondary annotation used by many projects, not just Spring Cloud Stream; as far as I know, there is nothing that will look for it on its own.

Try Spring Integration's @Publisher annotation instead (with @EnablePublisher).

EDIT

To force proxying with CGLIB instead of a JDK proxy, you can do this...

@Bean
public static BeanFactoryPostProcessor bfpp() {
    return bf -> {
        bf.getBean(IntegrationContextUtils.PUBLISHER_ANNOTATION_POSTPROCESSOR_NAME,
                PublisherAnnotationBeanPostProcessor.class).setProxyTargetClass(true);
    };
}
