Results Overview

Aspire + Java Integration Proposal

See 2024 JetBrains Java Developer Survey and Spring Boot Statistics for context on the Java ecosystem.

Note: The Community Toolkit provides Java/Spring Boot hosting. Aspire 13 elevated Python and JavaScript to first-class citizens with polyglot connection properties including JDBC format. This proposal outlines bringing Java to the same first-class status.

Executive Summary

Java is the second most popular enterprise language after JavaScript/TypeScript, with Spring Boot dominating the web framework space (~70% of Java web applications). With Aspire 13's rebrand from ".NET Aspire" to "Aspire" and first-class Python/JavaScript support, Java is the natural next step. This document outlines a Spring Boot-centric approach while maintaining flexibility for other Java frameworks.
