问题
I have to setup the flows dynamically.
Example:
@Component
@Slf4j
public class FTPFlow {
@Autowired
private IntegrationFlowContext integrationFlowContext;
@EventListener(ApplicationReadyEvent.class)
public void setup(){
integrationFlowContext.registration(flow()).register();
}
public IntegrationFlow flow() {
DefaultFtpSessionFactory defaultFtpSessionFactory = new DefaultFtpSessionFactory();
defaultFtpSessionFactory.setHost("localhost");
defaultFtpSessionFactory.setPort(252);
defaultFtpSessionFactory.setUsername("user");
defaultFtpSessionFactory.setPassword("password");
return IntegrationFlows.from(Ftp.inboundAdapter(defaultFtpSessionFactory).preserveTimestamp(true)
.localDirectory(new File("D:/tools/input"))
.regexFilter("yo.txt")
.remoteDirectory("/testing")
.deleteRemoteFiles(true),
e -> e.poller(Pollers.fixedDelay(10, TimeUnit.SECONDS)))
.transform((GenericTransformer<File, File>) file -> {
log.info("Dummy transformer. ");
return file;
})
.handle(o -> {
log.info("history {}", o.getHeaders());
})
.get();
}
}
The springboot application:
@SpringBootApplication
@EnableMessageHistory
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
The headers don't contain the history but if I don't use the IntegrationContext and use the @Bean directly on the method flow then I can see the history.
Do I have to enable the history when using IntegrationFlowContext?

I actually found out myself. Just adding answer for other people
When you are using IntegrationFlowContext you have to provide the "id" otherwise the history is not reserved.
integrationFlowContext.registration(flow()).id("tesflow").register();
