QUESTION
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 18:32Well, 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.

QUESTION
I successfully built a WordPress widget that, when a page is refreshed, downloads .csv files via their URLs found in a JSON file. The widget works perfectly; each time the page is refreshed, the .csv files are downloaded from their URLs in the JSON.
Now I am taking the code from the widget and pasting it into a plugin that does the same thing each day via a cron job. Unfortunately, the exact same code now doesn't work when triggered by the cron job.
While I can't post all the code due to security reasons, here's the excerpt where I'm encountering the bug.
...ANSWER
Answered 2021-Jun-11 at 13:36Running the cron job manually via the plugin "Advanced Cron Manager" caused the glitch. When the cron job runs automatically, there's no issue. Solved!

I'm trying to start an InboundChannelAdapter manually using a @Scheduled function. I think I'm setting up the message payload wrong but I'm not sure what to have it as. Here's the code:
...ANSWER
Answered 2021-Jun-11 at 07:39You are using an outdated API.
The annotation-based configuration model has been long deprecated in favor of functional programming model, so EnableBinding
, StreamListener
etc are on their way out.
For you case you can simply use Supplier with StreamBridge. See this section for more details. And then you can do programmatic start/stop binding using the available lifecycle features of spring-cloud-stream.
Now, that doesn't mean your other problem will be resolved, but without a full stack trace and sufficient detail (e.g., version of frameworks you are using) it is difficult to say.
