feat : handle transactions effectively #396
Conversation
WalkthroughThe recent changes enhance the transaction management and caching strategies across various service classes in the application. Several methods are now clearly defined as read-only, improving performance and ensuring data integrity. Additionally, new conditions and architectural rules have been established to enforce these practices throughout the codebase, fostering a more robust framework for managing transactions. Changes

31-31: Review read-only transaction annotation usageThe
@Transactional(readOnly = true)annotation in theHistoricalNavServiceclass is not suitable because the class contains methods that perform write operations to the database, such asschemeService.saveEntity. Consider revising the transaction management strategy to accommodate these operations.
- Method containing write operation:
schemeService.saveEntity(mfSchemeEntity)Analysis chain
Verify read-only transaction suitability.
The
@Transactional(readOnly = true)annotation has been added to the class. Ensure that all methods in this class do not perform any write operations to the database, as this annotation is intended for read-only operations.Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Verify if any methods in HistoricalNavService perform write operations. # Test: Search for potential write operations within the class.

src/main/java/com/learning/mfscreener/service/SchemeService.java (1)
157-157: Consider extending exception handling inmergeList.The
mergeListmethod currently handlesConstraintViolationExceptionandDataIntegrityViolationException, which is a good start. However, consider reviewing the transaction handling to ensure all potential exceptions are covered, such as general SQL exceptions or other runtime exceptions, to prevent unhandled exceptions from affecting application stability.
- Review exception handling in the
mergeListmethod for completeness.Analysis chain
Review transaction handling in
mergeList.The use of
transactionTemplate.executeWithoutResultprovides better transaction management. Ensure that error handling is robust and that all potential exceptions are considered.Scripts executed

src/main/java/com/learning/mfscreener/service/FIFOUnitsService.java (1)
29-29: Conflict with @transactional(readOnly = true) DetectedThe
FIFOUnitsServiceclass contains methods that likely perform write operations, such asbuyandsell, which conflict with the@Transactional(readOnly = true)annotation applied at the class level. Consider reviewing these methods to ensure they align with the read-only transactional context or adjust the transactional settings accordingly.
- Methods:
buy,sellAnalysis chain
Ensure all methods are read-only.
The addition of
@Transactional(readOnly = true)at the class level optimizes performance for read operations. Verify that no methods perform write operations, as this would conflict with the read-only setting.Scripts executed

Propagation.REQUIRES_NEW in
saveEntityMethodThe use of
Propagation.REQUIRES_NEWin thesaveEntitymethod ofUserCASDetailsServiceensures that it operates in a separate transaction, even when called from a read-only transactional context likePortfolioService. This is intentional and helps maintain data integrity. However, monitor for increased resource usage due to multiple transactions.
