meixuesong/aggregate-persistence

This system is a Java library for aggregate persistence, providing mechanisms to detect changes in domain objects through deep comparison and deep copying. It enables the creation of snapshots and the generation of field-level deltas to track state modifications. The codebase includes comprehensive test coverage for these features, validating behavior across complex object graphs and various data types.

The library now provides built-in support for deep comparison and deep copying of aggregate roots. A new \DeepComparator\ interface and \JavaUtilDeepComparator\ implementation allow the \Aggregate\ class to detect changes by comparing the current root with its snapshot. Additionally, a \DeepCopier\ interface and \SerializableDeepCopier\ implementation enable deep copying of objects, which is used to create snapshots of the aggregate root. These changes facilitate more robust change detection and state management within the aggregate pattern.

src/main · high confidence

Added deep equality tests for aggregate persistence; Added test fixtures for complex object persistence; Added tests for aggregate persistence and data object utilities.

The project has been initialized with a new pom.xml that targets Java 21 and includes updated dependencies, including junit 4.13.1, mockito-core 4.11.0, and commons-lang3 3.18.0. The build is configured to use the Maven compiler plugin 3.12.1, and release profiles are set up for publishing to the Central Repository.
