Spring-integration DSL：如何以编程方式获得集成流的默认通道？

Question

@Bean
public IntegrationFlow flow(){
    return f->f
            .handle(m ->{System.out.println(m);throw  new RuntimeException("probleme");});

}

鉴于此流程，我如何以编程方式获取默认通道（“flow.input”）？

Answer 1

@Autowired
@Qualifier("flow.input")
private MessageChannel flowInputChannel;

要么

MessageChannel flowInputChannel = applicationContext.getBean("flow.input", MessageChannel.class);
