Description

Rqueue currently creates its default ObjectMapper with minimal configuration only.
This can cause default enqueue/dequeue round-trip failures for payload types that
depend on Jackson modules present on the application classpath.

This PR updates the default mapper creation path to call findAndAddModules()
so that the default message conversion path is more consistent for enqueue,
dequeue, and listener argument mapping.

Changes:

  • update SerializationUtils.createObjectMapper() to use findAndAddModules()
  • add a regression test for the default GenericMessageConverter round-trip path

Fixes # (issue number if available)

Type of change

  • Bug fix (non-breaking change which fixes an issue)
  • New feature (non-breaking change which adds functionality)
  • Breaking change (fix or feature that would cause existing functionality to not work as expected)
  • This change requires a documentation update

How Has This Been Tested?

Prevent default message round-trip failures for module-backed payloads
215aee3
The default mapper bootstrap only disabled unknown-property failures,
so payloads that depend on Jackson module discovery could serialize on
enqueue and still fail during dequeue or listener argument mapping.
This change enables module auto-discovery in SerializationUtils and
adds a regression test that verifies the default GenericMessageConverter
round-trip path with a ServiceLoader-discovered Jackson module.
Constraint: Must preserve the existing MessageConverterProvider-based extension model
Rejected: Prefer Spring-managed ObjectMapper by default | changes the library's default configuration contract
Confidence: medium
Scope-risk: narrow
Directive: If default mapper bootstrap changes again, keep equivalent regression coverage for service-loaded modules
Tested: ./gradlew checkFormatJava :rqueue-core:test --tests com.github.sonus21.rqueue.converter.GenericMessageConverterTest --tests com.github.sonus21.rqueue.converter.JsonMessageConverterTest
Not-tested: Cross-service producer/consumer environments with different classpaths

Hi @JiHongKim98 , this will merge change to version 4.x, are you using spring spring boot 4.x?

I have a few questions regarding the release process.

I noticed that there are newer versions available on Maven Central (e.g. 3.4.1, 4.0.0-RC),
but GitHub releases seem to stop at v3.4.0.

Is there a reason why newer versions are not published as GitHub releases?

I have a few questions regarding the release process.
I noticed that there are newer versions available on Maven Central (e.g. 3.4.1, 4.0.0-RC),

but GitHub releases seem to stop at v3.4.0.
Is there a reason why newer versions are not published as GitHub releases?

Description
Rqueue currently creates its default ObjectMapper with minimal configuration only.

This can cause default enqueue/dequeue round-trip failures for payload types that

depend on Jackson modules present on the application classpath.
This PR updates the default mapper creation path to call findAndAddModules()

so that the default message conversion path is more consistent for enqueue,

dequeue, and listener argument mapping.
Changes:
  • update SerializationUtils.createObjectMapper() to use findAndAddModules()
  • add a regression test for the default GenericMessageConverter round-trip path
Fixes # (issue number if available)
Type of change
  •  Bug fix (non-breaking change which fixes an issue)
  •  New feature (non-breaking change which adds functionality)
  •  Breaking change (fix or feature that would cause existing functionality to not work as expected)
  •  This change requires a documentation update
