            How to publish two messages of the same type to different worker instances based on the message content without using Send and RequestAddress?
            Asked 2021-Jun-16 at 03:47

            How to publish two messages of the same type to different worker instances based on the message content without using Send and RequestAddress?

            My scenario is:

            I am using Azure ServiceBus and Azure StorageTables.

            I am running two different instances of the same worker service workera and workerb. I need workera and workerb to both consume messages of type Command based on the value of Command.WorkerPrefix.

            the Command type looks like:



            Answered 2021-Jun-15 at 23:37

            Using MassTransit with Azure Service Bus, I would suggest taking the message routing burden away from the publisher, and moving it to the consumer. By configuring the receive endpoint and using a subscription filter each instance would add its own subscription and use a message header to filter published messages.

            On the publisher, a message header would be added:



            How do I use a Transaction in a Reactive Flow in Spring Integration?
            Asked 2021-Jun-15 at 18:32

            I am querying a database for an item using R2DBC and Spring Integration. I want to extend the transaction boundary a bit to include a handler - if the handler fails I want to roll back the database operation. But I'm having difficulty even establishing transactionality explicitly in my integration flow. The flow is defined as



            Answered 2021-Jun-15 at 18:32

            Well, it's indeed not possible that declarative way since we don't have hook for injecting to the reactive type in the middle on that level.

            Try to look into a TransactionalOperator and its usage from the Java DSL's fluxTransform():

            I know there are some other questions (with answers) to this topic. But no of these was helpful for me.

            Here I'm wondering about the line [in s_client]
            New, TLSv1/SSLv3, Cipher is ECDHE-RSA-AES256-GCM-SHA384

            You're apparently using OpenSSL 1.0.2, where that's a basically useless relic. Back in the days when OpenSSL supported SSLv2 (mostly until 2010, although almost no one used it much after 2000), the ciphersuite values used for SSLv3 and up (including all TLS, but before 2014 OpenSSL didn't implement higher than TLS1.0) were structured differently than those used for SSLv2, so it was important to qualify the ciphersuite by the 'universe' it existed in. It has almost nothing to do with the protocol version actually used, which appears later in the session-param decode:



            How to test stream-based API in .NET
            Asked 2021-Jun-15 at 05:30

            I'm developing internal messaging protocol that is based on TCP. Everything works, but I want to add tests to it.

            It is possible to test serialization/deserialization with MemoryStream, but I can't find a way to test this thing as whole - with contiguous message interchange, because MemoryStream "ends" after reading first message.

            The question: Is there a stream that behaves like NetworkStream (duplex, ends only when other end closed, can't seek) in base library or any nuget package?

            Currently I can start 2 TcpClients and use them, but I think it have too much overhead for tests especially when there's hundreds of tests running simultaneously

            Reply Channel for Messaging Gateway using Java DSL
            Asked 2021-Jun-14 at 14:28

            I have a REST API which receives a POST request from a client application.



            Answered 2021-Jun-14 at 14:28

            Your current flow does not return a value, you are simply logging the message.

            A terminating .log() ends the flow.

            Delete the .log() element so the result of the transform will automatically be routed back to the gateway.

            Or add a .bridge() (a bridge to nowhere) after the log and it will bridge the output to the reply channel.

            I had the same error as like you, on the same line. I checked out docs and it says 2 things about background message handler.

            1. It must not be an anonymous function.
            2. It must be a top-level function (e.g. not a class method which requires initialization).

            In my case it was not a top-level function, it was declared inside a class. When you move your handler out of any class or function, so that it is a top-level function and doesn't require any class or method initialisation then the error will be gone.



            Python: Is there any issue with using __getattribute__ within a class?
            Asked 2021-Jun-13 at 20:37

            I have created a class for managing subscriptions to a messaging service. The class instantiates three separate clients for reasons related to the configuration for each subscription, also three per instance of the class. To reduce the instantiation of the three clients to one for loop, I've used __getattribute__ and __setattr__. I've read other threads about these methods, and I'm not sure if using them as I have could lead to issues. Here is a very simplified example:



            Answered 2021-Jun-13 at 20:37

            Instead of using the dunder methods __setattr__/__getattr__ (or __getattribute__), you should use getattr(self, client) and setattr(self, client, value)...

            but better yet, you should just use a dict if you need to map names to objects.

            hope you are doing well. Here are the steps I have done to pass through the loading page:

            1. Make sure you have correctly installed the firebase packages and added the firebase config file into your project as the document stated: document

            2. Open the firebase console and go into the crashlytics page (the screenshot you have shown in this question)

            3. You need to manually make a crash in your app. Please call the below function somewhere inside your app (better assign to a button and click it to trigger)



            Kafka Consumer Unable To Resolve Listener Method Intermittently
            Asked 2021-Jun-11 at 19:58

            I have been facing the exception below on the Kafka consumer side. Surprisingly, this issue is not consistent and an older version of the code (with the exact same configuration but some new unrelated features) works as expected. Could anyone help in determining what could be causing this?



            Answered 2021-Jun-11 at 19:58

            You don't need all the standard @KafkaListener method invoking infrastructure when your listener already implements one of the message listener interfaces; instead of registering endpoints for each listener, just create a container for each from the factory and add the listener to the container properties.
