split-route-aggregate flow
split之后，可以將message分給不同的子flow處理，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");
}
