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

...ANSWER
Answered 2021-Jun-15 at 06:57This is because your ItemProcessorSurveillance implements two interfaces: ItemProcessor and StepExecutionListener but is only registered as an ItemProcessor in the step. It should also be registered as a listener so that beforeStep is called when appropriate to set the stepExecution field.

** I am implementing role-based access control to my application. There are 3 users(Admin, Teacher, Student) in the application with same attribute so I created a basedUser entity to let them inherit it.

Answered 2021-Jun-13 at 15:15The log shows that the ResourcesPlugin is being found but its plug-in activator is getting a null pointer exception when it tries to get the IContentTypeManager.
The content type manager is provided using OSGi declarative services but you have not included org.apache.felix.scr which deals with this.
So at a minimum you need to include org.apache.felix.scr and start it in the section:

Need some help here, I'm not able to understand why my transactions are not getting rolled back in an event of exception.

This is my Service
...ANSWER
Answered 2021-Jun-11 at 12:22The method PublicationServiceImpl.save must be public if you want to use @Transactional.
As per Spring Documentation:
When you use transactional proxies with Spring’s standard configuration, you should apply the @Transactional annotation only to methods with public visibility. If you do annotate protected, private, or package-visible methods with the @Transactional annotation, no error is raised, but the annotated method does not exhibit the configured transactional settings.

...ANSWER
Answered 2021-Jun-10 at 17:33it's BROKER_1.FOO.NET:9094, and it is available.
The bootstrap port may be available and responding to requests, but that broker then returned it's configured advertised.listeners.
Based on your error, either
- that's set to be localhost/127.0.0.1:9092
- or you're getting the default Spring property for the bootstrap servers config

I'm using SignalR on ASP.NET Core 5 web server for Android device management. I can send messages from device (D2C), and receive messages with String parameters (C2D). But I can't receive messages with custom object parameters, the handler receives all object members as null. I develop an WPF client and it receives this object well.
I'm following ASP.NET Core SignalR Java client documentation. It explains how to use custom objects in Passing Class information in Java section.
In build.gradle file:

Answered 2021-Jun-10 at 13:49It seems that in the java client the custom object field names should be in lowercase. So changing the field names solves the problem.

QUESTION
I am using spring-batch in spring-boot application. The Spring Boot version is 2.3.3.RELEASE.
What I intend to achieve
I have to read a xml file containing thousands of Transactions with header tag (fileInformation). Do some business logic on transaction and then write the file back with the updated values in transaction. I am using StaxEventItemReader for reading the file and StaxEventItemWriter for writing to the file. Then i have couple of ItemProcessors for handling the business logic. Xml file looks like :
ANSWER
Answered 2021-Jun-10 at 07:38You step is doing too much. I would beak things down to two steps:
- Step 1: extracts the file information header and puts it in the job execution context
- Step 2: reads the file information header from the execution context and uses it in whatever step-scoped bean needed for that step (for example the stax callback in your case)
