Spring集成DSL：如何以編程方式獲取集成流的默認通道？

Question

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

} 

鑑於此流程，我怎樣才能以編程方式獲得默認通道（「flow.input」）？

Answer 1

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

或

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