I'm using Spring-integration java dsl in my project and I want to add configurable timeout for the parallel services that are being called. I should be able to add different timeout for thr different flows that I'm using here. Kindly help me with this.
Below is the codebase :
Config file
@Configuration
public class IntegrationConfiguration {
@Autowired LoansServiceImpl loansService;
long dbId = new SequenceGenerator().nextId();
// Main flow
@Bean
public IntegrationFlow flow() {
return flow ->
flow.split()
.log()
.channel(c -> c.executor(Executors.newCachedThreadPool()))
.convert(LoanProvisionRequest.class)
.scatterGather(
scatterer ->
scatterer
.applySequence(true)
.recipientFlow(flow1())
.recipientFlow(flow2())
.recipientFlow(flow3()),
gatherer -> gatherer.releaseLockBeforeSend(true))
.log()
.aggregate(a -> a.outputProcessor(MessageGroup::getMessages))
.channel("output-flow");
}
// flow1
@Bean
public IntegrationFlow flow1() {
return integrationFlowDefination ->
integrationFlowDefination
.channel(c -> c.executor(Executors.newCachedThreadPool()))
.handle(
message -> {
try {
lionService.saveLionRequest(
(LionRequest) message.getPayload(), String.valueOf(dbId));
} catch (JsonProcessingException e) {
throw new RuntimeException(e);
}
});
}
// flow2
@Bean
public IntegrationFlow flow2() {
return integrationFlowDefination ->
integrationFlowDefination
.channel(c -> c.executor(Executors.newCachedThreadPool()))
.handle(
message ->
lionService.getData(
(LionRequest) message.getPayload(), SourceSystem.PROVISION))
.log();
}
// flow3
@Bean
public IntegrationFlow flow3() {
return integrationFlowDefination ->
integrationFlowDefination
.channel(c -> c.executor(Executors.newCachedThreadPool()))
.handle(
message ->
lionService.prepareCDRequest(
(LionRequest) message));
}
@Bean
public MessageChannel replyChannel() {
return MessageChannels.executor("output-flow", outputExecutor()).get();
}
@Bean
public ThreadPoolTaskExecutor outputExecutor() {
ThreadPoolTaskExecutor pool = new ThreadPoolTaskExecutor();
pool.setCorePoolSize(4);
pool.setMaxPoolSize(4);
return pool;
}
}
Gateway
@MessagingGateway
public interface LionGateway {
@Gateway(requestChannel = "flow.input", replyChannel = "output-flow")
List<?> echo(LionRequest lionRequest);
}
Controller
@Autowired private LionGateway lionGateway;
@PostMapping(value = "/invoke-integration")
public String invokeIntegrationFlow(@RequestBody LionRequest lionRequest) {
String response1 = lionGateway.echo(lionRequest).get(0);
String response2 = lionGateway.echo(lionRequest).get(1);
System.out.Println("response2 ")
System.out.Println("response1 ")
return "response";
}
