是否可以在运行时使用spring-integration-dsl?
注册MessageSources在我的情况下,我想创建多个FileReadingMessageSources(基于来自UI的输入),然后将有效负载发送到特定的channel / jms路由(从元数据或用户输入读取)
另一个问题是,是否可以动态注册IntegrationFlows?
答案 0 :(得分:3)
这有点棘手,需要一些Spring基础知识知识,但是有可能:
@Service
public static class MyService {
@Autowired
private AutowireCapableBeanFactory beanFactory;
@Autowired
@Qualifier("dynamicAdaptersResult")
PollableChannel dynamicAdaptersResult;
public void pollDirectories(File... directories) {
for (File directory : directories) {
StandardIntegrationFlow integrationFlow = IntegrationFlows
.from(s -> s.file(directory),
e -> e.poller(p -> p.fixedDelay(1000))
.id(directory.getName() + ".adapter"))
.transform(Transformers.fileToString(),
e -> e.id(directory.getName() + ".transformer"))
.channel(this.dynamicAdaptersResult)
.get();
this.beanFactory.initializeBean(integrationFlow, directory.getName());
this.beanFactory.getBean(directory.getName() + ".transformer", Lifecycle.class).start();
this.beanFactory.getBean(directory.getName() + ".adapter", Lifecycle.class).start();
}
}
}
请调查我的样本,并告诉我你不清楚的事情。
