SPRING INTEGRATION子FLOW

split-route-aggregate flow 
split之后,可以将message分给不同的子flow处理,配置如下:
@Bean
public IntegrationFlow parallelSplitRouteAggregateFlow() {
    return IntegrationFlows
            .from(Http.inboundGateway("/trigger"))
            .handle((p, h) -> Arrays.asList(1, 2, 3))
            .split()
            .channel(MessageChannels.executor(Executors.newCachedThreadPool()))
            .<Integer, Boolean>route(o -> o % 2 == 0, m -> m
                    .subFlowMapping(true, sf -> sf.gateway(oddFlow()))
                    .subFlowMapping(false, sf -> sf.gateway(evenFlow())))
            .aggregate()
            .get();
}

@Bean
public IntegrationFlow oddFlow() {
    return flow -> flow.<Integer>handle((payload, headers) -> "odd");
}

@Bean
public IntegrationFlow evenFlow() {
    return flow -> flow.<Integer>handle((payload, headers) -> "even");
}
