Best Java Libraries 2024: Community Voting Results

The Java Community Has Chosen the Best Libraries of the Year: 2024 Results

The annual vote among Java developers has concluded. This year, the community selected the best libraries that significantly simplify application development, testing, and deployment. We have gathered the key categories and winners to keep you up to date with current trends.

Categories and Winners

The voting took place in six main categories. Here is the list of libraries that received the highest number of votes:

• Best Library for Development: Spring Boot — a long-time leader among frameworks, simplifying the creation of microservices and enterprise applications.
• Best Library for Testing: JUnit 5 — the standard for unit testing, which received updates with support for new Java features.
• Best Library for Database Work: Hibernate — an ORM solution that continues to evolve, offering improved performance and compatibility with Jakarta EE.
• Best Library for DevOps and CI/CD: Maven — despite competition from Gradle, this tool remains a favorite due to its maturity and vast number of plugins.
• Best Library for Data Processing: Apache Spark — the choice for Big Data and stream processing, actively used in Data Science projects on Java.
• Best Library for Security: Spring Security — a reliable solution for authentication and authorization, which has been updated with support for OAuth 2.1.

Trends of 2024

Analysts note several interesting trends based on the voting results:

• Growing popularity of reactive programming. Projects based on Spring WebFlux and Project Reactor are gaining momentum, although they still lag behind classic Spring Boot.
• Strengthening positions of cloud libraries. Tools for working with Kubernetes and cloud providers (e.g., Quarkus and Micronaut) made it into the top 5 in several categories.
• Focus on performance. The community prefers libraries that minimize overhead and support virtual threads (Project Loom).

Why Is This Important for Developers?

Knowing the best libraries helps reduce development time, avoid common mistakes, and stay competitive in the job market. For example, using Hibernate instead of direct JDBC queries can speed up the creation of complex queries, and JUnit 5 can improve code quality through enhanced test parameterization capabilities.

The full list of nominees and voting results are available on the official Java community website. We also recommend paying attention to the newcomers of the year — the Lombok and MapStruct libraries, which significantly reduce the amount of boilerplate code.
