spring-projects/spring-data-jpa

This system is the Spring Data JPA project, a framework that provides repository support for JPA-based data access. It includes a newly introduced module for Hibernate Envers to manage entity revision history and query revisions. The codebase also features tooling for build standardization, static analysis, and performance benchmarking of repository query methods.

This change introduces new configuration and benchmarking assets for the Spring Data JPA module. It adds a Sonargraph architecture definition file (\Spring Data JPA.sonargraph\) that defines the project's internal layering (Support, Repository, Domain, Mapping, Utilities) and external subsystem dependencies (Querydsl, Spring, Spring Data Commons), along with code quality thresholds. It also includes an AspectJ configuration file (\aop.xml\) to enable \AnnotationBeanConfigurerAspect\ for dependency injection, and a Java code formatting profile (\formatting.xml\) named "Spring Data" to standardize code style. Additionally, JMH benchmark classes (\AotRepositoryQueryMethodBenchmarks.java\ and \RepositoryQueryMethodBenchmarks.java\) are added to measure the performance of AOT-generated repository query methods against standard reflective ones.

This change introduces the new spring-data-envers module, providing Spring Data repository support for Hibernate Envers revision history. It includes the \@EnableEnversRepositories\ annotation for configuration, core repository interfaces and implementations (\EnversRevisionRepository\, \EnversRevisionRepositoryImpl\) to query entity revisions, and support classes (\DefaultRevisionMetadata\, \ReflectionRevisionEntityInformation\) to handle both default and custom revision entities. The implementation enables paginated and sorted revision queries and integrates with the standard Spring Data repository infrastructure.

The ANTLR code generator template has been updated to include JSpecify annotations (such as @NullUnmarked) in the generated Java parser, listener, base listener, and visitor classes. This change improves static analysis and null-safety checking for users of the generated code by providing explicit nullability information, replacing previous approaches that may have relied on other mechanisms or lacked such annotations.

The Maven build now integrates the Spring Develocity Conventions extension (version 0.0.26) to standardize build behavior and reporting. Additionally, the JVM configuration has been updated to include specific exports and opens for JDK compiler modules and base libraries, ensuring compatibility with the new build conventions and tooling requirements.

The project dependencies and build configuration have been updated to the 4.2.0-SNAPSHOT release line. This includes upgrading the core Spring Data Commons dependency to 4.2.0-SNAPSHOT, setting the default Hibernate version to 7.4.9.Final, and updating EclipseLink to 5.0.1. Test infrastructure dependencies have also been refreshed, including H2 to 2.5.250, PostgreSQL JDBC driver to 42.7.13, MySQL JDBC driver to 26.7.0, Oracle JDBC driver to 23.26.3.0.0, and JSqlParser to 5.4. The build now supports testing against Hibernate 8.0.0.Beta1 and 8.1.0-SNAPSHOT via dedicated profiles, and includes Testcontainers support for MySQL, PostgreSQL, and Oracle.

The Maven Wrapper configuration has been updated to use Maven distribution version 3.9.16. This ensures that builds executed via the wrapper will consistently use this specific Maven version, improving reproducibility and potentially providing access to the latest features and bug fixes available in that release.

.mvn/wrapper · high confidence

The repository has been initialized with essential project files, including a .gitignore configuration to exclude build artifacts and IDE settings, a Maven wrapper (mvnw/mvnw.cmd) to ensure consistent builds, and standard documentation files such as README.adoc, CONTRIBUTING.adoc, CI.adoc, and SECURITY.adoc. The project is licensed under the Apache License 2.0, and obsolete placeholder files have been removed.
