What Hibernate-SpringBoot is

Repository of Spring Boot + Hibernate 5/6 samples demonstrating performance tuning techniques: batch insert strategies via JpaRepository and EntityManager, DataSource-Proxy query profiling, prepared statement caching, server-side prepared statements, persistence context management, and database-specific optimizations (MySQL, PostgreSQL).

Quickstart

Get the Hibernate-SpringBoot source

Clone the repository and explore it locally.

terminalbash

1git clone https://github.com/AnghelLeonard/Hibernate-SpringBoot.git2cd Hibernate-SpringBoot3# follow the project's README for install & configuration

Best use cases

Performance Tuning Reference for Spring Boot Teams

Use as a living document and code reference when optimizing Hibernate/JPA applications. Each example includes configuration, implementation, and explains trade-offs and when to apply each pattern.

Learning Resource for Persistence Best Practices

Developers new to Spring Boot persistence can study runnable examples covering N+1 query problems, batching, caching, and timezone management without needing to construct samples from scratch.

Performance Audit & Code Review Baseline

Architecture/engineering teams can reference examples during code reviews to validate that batch sizes, connection pooling, and query strategies align with documented best practices.

Implementation considerations

Examples target MySQL and PostgreSQL; verify JDBC URL parameters (rewriteBatchedStatements, cachePrepStmts, useServerPrepStmts) are safe for your database and driver version.
Batch sizing and Persistence Context flushing must be tuned per workload; blindly copying batch_size=30 may cause memory pressure or diminishing throughput on your dataset.
Requires Log4J 2 or DataSource-Proxy integration for query profiling; excludes or augments Spring Boot's default logging, which may complicate centralized log aggregation.
Entity lifecycle management (@Version, assigned generators, cascade policies) varies by use case; patterns shown are not universal and need adaptation to your domain model.
Timezone handling and prepared statement caching introduce edge cases (legacy JDBC behavior, server-side state) that demand testing in your target environment.

When to avoid it — and what to weigh

Need Actively Maintained Framework — No releases published (latestRelease: none). Last push 2026-03-25 is recent, but absence of versioned releases signals this is a reference collection, not a dependency or framework to import as a library.
Require Spring Boot 3.x+ or Hibernate 7+ Support — README explicitly directs Spring Boot 3/Hibernate 7 users to a separate repository. This collection targets Hibernate 5/6 and Spring Boot 2; upgrade compatibility is not guaranteed.
Looking for a Plug-and-Play Library — This is example code and documentation, not a reusable library or framework. Copy-paste and adaptation are expected; no versioned artifact to depend on.
Production-Critical Deployment Without Expertise — Examples require understanding of Hibernate internals, JDBC settings, and database-specific optimizations. Without team expertise in persistence tuning, misapplying patterns can introduce subtle bugs.

License & commercial use

Licensed under Apache License 2.0 (Apache-2.0), a permissive OSI-approved license. Source code, examples, and documentation are freely usable, modifiable, and redistributable under Apache 2.0 terms.

Apache 2.0 permits commercial use of the example code and patterns. However, this is a reference repository, not a library dependency. If you copy code into a commercial product, you must include a copy of the Apache 2.0 license and state any material modifications. Consult your legal team if you plan to redistribute or rebrand the repository contents. The author's associated books (Spring Boot Persistence Best Practices, Java Persistence Performance Illustrated Guide) are separate commercial products.

Security considerations

No security audit mentioned. Examples cover timezone UTC handling and SQL preparation, which are relevant to injection prevention. However, as example code, security considerations are not centralized: developers must review each pattern for their threat model. Prepared statements (when configured correctly) reduce SQL injection risk; server-side prepared statements add complexity and potential for statement plan DoS. No mention of connection pool security (credential rotation, network isolation).

Alternatives to consider

Hibernate-SpringBoot-4 (Spring Boot 3/Hibernate 7 variant)

If targeting Spring Boot 3.x or Hibernate 7+, the author maintains a separate repository with up-to-date examples. This project explicitly references it for modern stack users.

Vlad Mihalcea's Blog & High-Performance Java Persistence Book

Covers similar JPA/Hibernate optimization topics with deep technical explanations and benchmarks. Complementary written format; some patterns in this repo reference Vlad's work.

Spring Data JPA Documentation + Official Hibernate Guides

Authoritative sources for Spring Boot persistence. Less comprehensive on advanced batching and tuning but offer official support and are kept current with releases.

Hibernate-SpringBoot FAQ

Can I use this code directly in production?

Yes, as reference patterns and example code. Copy and adapt examples to your codebase, test thoroughly in your environment, and validate performance gains with your data. Do not assume patterns are universally optimal; tuning is workload-specific.

Is this library actively maintained and will it receive updates?

The repository is maintained (recent pushes) but not released as versioned artifacts. It is a curated collection of examples, not a framework. For Spring Boot 3.x/Hibernate 7+, the author directs users to a separate repository.

What if my database or Spring Boot version differs from the examples?

Examples target MySQL, PostgreSQL, Hibernate 5/6, and Spring Boot 2. Patterns are portable but require validation: JDBC URL settings, Hibernate properties, and API calls may differ. Test in your environment before production deployment.

Can I depend on this as a Maven/Gradle library?

No, this is a reference repository with standalone example projects, not a published library. Clone or copy examples into your codebase and adapt them.
