Spring integration dsl: http outbound gateway - java

Faced spring integration java-dsl issue, I'm stuck. This is a code I have for my flow declaration:
#Bean
public IntegrationFlow orchestrationFlow() {
return IntegrationFlows.from(
Jms.messageDrivenChannelAdapter(queueConnectionFactory())
.destination(bookingQueue())
.outputChannel(bookingChannel()))
.<String, BookingRequest>transform(s -> {
Ticket t = new Gson().fromJson(s, Ticket.class);
return new BookingRequest()
.setMovieId(t.getMovie().getId())
.setRow(t.getSeat().getRow())
.setSeat(t.getSeat().getNumber())
.setScreenNumber(t.getScreenNumber()
);
})
// HTTP part goes here
.<BookingRequest, HttpEntity>transform(HttpEntity::new)
.handle(
Http.outboundChannelAdapter(bookingServerUrl)
.httpMethod(HttpMethod.POST)
.extractPayload(true)
.expectedResponseType(BookStatus.class)
)
// and here HTTP part ends
.handle(
Jms.outboundAdapter(responseDestinationTemplate())
)
.get();
}
And everything was OK until I utilized HTTP outbound channel adapter. I need to call simple RESTful interface and code above does it pretty well. But, following Jms.outboundAdapter(responseDestinationTemplate()) line leads to nothing, no action performes after successfull http call.
If I remove http flow part (surrounded by comments) - it works. Implemented so much stuff, almost understood and saw beauty and simplicity of integration ...aand this is it. Yet another place I got stuck in.
And here are log after success REST call:

No errors, no warnings at all.


Spring Integration provides two MessageHandler types: one-way - just handle message and stop. And another one is like: handle request message and produce reply to the output channel.
The first one is called like outboundChannelAdapter and with your HTTP case you just only send a POST request and don't worry about the reply.
Since the message flow is stopped on the outboundChannelAdapter no any further action is possible in the integration chain. Like in your case the next Jms.outboundAdapter won't be reached.
If you really expect the reply from your REST service you should use Http.outboundGateway instead. And your BookStatus will be sent to the JMS as you'd like by your last .handle() in the flow.

Java Spring Security Authentication Server does not display error description

My Java Spring Authentication and Authorization Server is working.
I want to solve the errors in the requests I send from a client according to the OAuth2 flow. But none of the errors I get are detailed. For example, this request sent to /oauth2/authorize:
https://MY_DOMAIN/authorize?
response_type=code&
client_id=MY_CLIENT_ID&
redirect_uri=MY_CALLBACK_URL&
scope=SCOPE&
state=STATE
Gives the following error after I enter credentials:
My goal is not to resolve the error here, but there are different errors I get like this and I need to see a more informative error message so I can debug them all.
The console also has a non-informative output that goes like this:

Springboot access header in Controller method

I have this controller method:
#GET
#Path("/watch/{groupId}")
public Response watch(#PathParam("groupId") UUID groupId, #RequestHeader("X-Session-ID") String sessionId) {
LOGGER.info("Header passed: " + sessionId);
/* Other stuff */
}
My expectation is that in my watch() method, I'll have the group ID (passed as a URL segment) as a UUID and the session ID (passed as a header) as a String in the corresponding variables. And while the group ID is passed, the header value isn't. This is my log excerpt:

As you can see, the log entry for the session ID is not showing anything.
I am out of ideas as to why this is happening. Can someone help?

OK, I have figured out the problem here.
#GET is javax.ws.rs.GET.
#Path is javax.ws.rs.Path.
#PathParam is javax.ws.rs.PathParam.
But #RequestHeader is org.springframework.web.bind.annotation.RequestHeader.
That is, I was mixing Spring's REST and JAX-RS's. I replaced #RequestHeader (Spring) with #HeaderParam (JAX-RS) and now I get the HTTP header's value in my code.
Which is better, which one should I use etc. I'll figure out later. Right now the problem is solved.

Zipkins(in spring boot Application) is not storing all the trace id's when i am sending 10 request from an application to other application

I am using ZIPKINS for distributed tracing the problem is when I am trying to test ZIPKINS by sending 10 request at a time to that service from other service by using loop, checked the UI for the logs of that, I had got only 2 logs i.e for first and last, I haven't received logs of the remaining requests. Can you help in figuring out what is the problem in that. Trace ids and span ids are generated for all the request, I am unable to see that logs for the same. Logs that are received:

Log format is: [application name, traceId, spanId, export]
So the last value true/false is actually the export value which means:
Export – This property is a boolean that indicates whether or not this log was exported to an aggregator like Zipkin. Zipkin is beyond the scope of this article but plays an important role in analyzing logs created by Sleuth.
As export values are false, zipkin is not receiving those values. That is expected behavior.
Root Cause: Some of the logs are exporting and some are not is because of sampler rate. Not all of the logs are meant to be sent. Anyway if you want all of the logs to be sampled try adding this property:
spring.sleuth.sampler.probability=1.0

Thank you Joe. The resource to implement 'Spring Cloud GCP Core' was never mentioned in the tutorials or i overlooked it.
Somehow another account was connected in my Google Cloud SDK on my console. So i used
gcloud auth application-default login
and logged in the right account. Now it works. Thank you.

This looks like an issue regarding authentication. Did you follow the generic 'Spring Cloud GCP Core' [1] configuration?
Check your application.properties [2] (or other configuration) and make sure it contains at least the following properties:
spring.cloud.gcp.datastore.project-id=XXX
spring.cloud.gcp.datastore.credentials.location=YYY
or choose an other method shown in [1].

Citrus Example TCP send and receive fails

I'm trying to send and receive a TCP message via Citrus-Framework, where I used this thread as a reference:
Receiving messages from tcp server with Citrus framework and Spring Integration times out
I'm using a python message repeater, which returns the received message. I receive a payload with python and returns it but citrus times out. I tried all serializers (except SingleTerminatior, causes a context error).
I tried different serializers but none seem to solve my problem, Citrus always times out.

My context seems to be right (I'm using spring-integration-ip 5.0.8-RELEASE), there is no exception when executing the test (except using SingleTerminatior):
<?xml version="1.0" encoding="UTF-8"?>

I appreciate any kind of help
Thanks
because I'm new to spring here is the dependency I added from my part:
<dependency>
<groupId>org.springframework.integration</groupId>
<artifactId>spring-integration-ip</artifactId>
<version>5.0.8.RELEASE</version>
</dependency>

This is the debug output of citrus:

I checked Wireshark and the payload ("Req") inclusive the linefeed was returned, which can be seen in the screenshot. Maybe I should mention I'm running this in an Ubuntu VM.
Wireshark screenshot
#CitrusTest(name = "sendSpringIntegrationMessageTest")
public void sendSpringIntegrationMessageTest() throws Exception {
send("citrusServiceInputEndpoint").payload("Req");
receive("citrusServiceRepliesEndpoint").payload("Req");
}
EDIT
ok there seem to be an issue in my python server. I changed the code a bit to see the received bytes on the console (before I was just counting the bytes) and suddenly the output of citrus changed.

Because of the following post:
How to use Spring Integration 5 with Spring Boot 1.5.x
I switched from spring-integration-ip 5.0.8 to 4.3.9 and there the output changed one more time. Now my problem seems to move away from TCP issues to actual spring know-how.

Seems like after adjusting my environment a lot for test, I was lastly missing this line in my context file:
<int:object-to-string-transformer id="transformer" input-channel="replies" output-channel="response" />
Thanks for nudging me into the right direction.
