Java ORM Libraries
Java ORM Libraries
Java ORM libraries provide enterprise-level features and maturity. Hibernate is the most widely used JPA implementation, Spring Data JPA offers Spring framework integration. MyBatis allows full SQL control, and JOOQ provides type-safe SQL query builders. They have proven track records in large-scale systems.
GitHub Star Comparison
| No | Name | GitHub Stars | Description | Trend | License | Type | Official Site |
|---|---|---|---|---|---|---|---|
| 1 | MyBatis | ⭐ 20.2k | MyBatis is a SQL-centric lightweight persistence framework that provides complete control over SQL statements. It supports both XML mapping files and annotation-based approaches, focusing on complex queries and high performance, with particular strength in enterprise legacy system integration for Java applications. | stable | Apache-2.0 | Library | Official |
| 2 | jOOQ | ⭐ 6.4k | jOOQ stands for "Java Object Oriented Querying" and is a library that provides the best way to write SQL in Java. Through database-first DSL (Domain Specific Language), it achieves type-safe query construction with SQL-like fluent API. With a special approach that balances complex SQL and type safety, you can leverage SQL knowledge while benefiting from Java's type system. It adopts an innovative approach that generates Java code from database schemas and guarantees SQL syntax accuracy at compile time. | stable | Apache-2.0 | Library | Official |
| 3 | Hibernate ORM | ⭐ 6.2k | Hibernate is the de facto standard ORM library in the Java ecosystem. As an Object-Relational Mapping (O/RM) tool, it elegantly connects object-oriented Java objects with relational databases. Standardized as part of Jakarta EE (formerly Java EE), it provides flexible data access through HQL (Hibernate Query Language) and Criteria API. | stable | LGPL-2.1 | Library | Official |
| 4 | Spring Data JPA | ⭐ 3.1k | Spring Data JPA is the official data access library of the Spring Framework, developed to "Simplify the development of creating a JPA-based data access layer". Based on Hibernate, which is an implementation of JPA (Java Persistence API), it significantly reduces boilerplate data access code through repository patterns and automatic query generation from method names. As of 2025, it serves as the de facto standard ORM library for Java enterprise application development and forms the core of the Spring Boot ecosystem. | stable | Apache-2.0 | Library | Official |
| 5 | EclipseLink | ⭐ 222 | EclipseLink is developed as "the official reference implementation of Java Persistence API (JPA)" and serves as an enterprise-level Object-Relational Mapping (ORM) framework. In addition to complete implementation of JPA 2.0 specification, it provides advanced caching capabilities, batch processing, and diverse database support. With strong backing from Oracle Corporation, it has a proven track record of stable operation in large-scale enterprise systems and has established itself as a standard choice for data persistence solutions in Java enterprise development. | stable | EPL-2.0 | Library | Official |
| 6 | OpenJPA | - | OpenJPA is Apache Software Foundation's JPA (Java Persistence API) implementation. It provides bytecode enhancement and query optimization features, characterized by lightweight and simple design as an open-source ORM. While complying with standard JPA specifications, it achieves flexible data access through proprietary extensions. | stable | MIT | Library | - |
