We recommend specifying the specific dataId and group directly through spring.config.import. If you need to specify a profile, we suggest using a ${} placeholder in the dataId, such as spring.cnfig.import=nacos: application-${profile}. yml&group=mygroup

Summary

This PR adds profile-specific configuration loading to NacosConfigDataLocationResolver, enabling Spring Cloud Nacos to load profile-aware config files (e.g., application-dev.yml alongside application.yml). This aligns with Spring Boot's standard config data behavior.

Review Notes

• Feature value: Profile-specific config loading is a standard Spring Boot feature. Adding it to the Nacos config data resolver improves consistency with Spring Cloud Config and Kubernetes config providers.
• Implementation: The getProfileConfigDataLocation() method correctly handles optional prefix, extension preservation, and query parameter positioning.
• [Warning] Backward compatibility: This changes the config loading behavior — existing deployments that rely on the current single-file loading may see additional config files being loaded. Please document this behavior change and consider adding a property to disable profile-specific loading if needed.
• [Info] Test coverage: Good that tests are included. Consider adding edge case tests for:
  • Config locations with query parameters (e.g., nacos:app.yml?group=xxx)
  • Multiple active profiles
  • Optional prefix handling (optional:nacos:app.yml)

Cross-repo Note

If this feature is merged, the official docs should be updated to explain profile-specific config loading behavior.
