Spring Framework

Spring is the leading open-source application framework for Java. The Spring ecosystem provides a comprehensive programming and configuration model for modern Java-based enterprise applications, covering web MVC, data access, security, messaging, cloud-native patterns, and AI integrations. Spring Boot enables rapid application development with embedded servers and auto-configuration. Spring is maintained by VMware and hosted under the Spring Projects GitHub organization.

Spring Framework publishes 10 APIs on the APIs.io network, including Beans API, Environment API, Health API, and 7 more. Tagged areas include AI, Cloud Native, Enterprise, Framework, and Java.

The Spring Framework catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

Spring Framework’s developer surface includes authentication, GitHub presence, documentation, engineering blog, release notes, and 8 more developer resources.
