Explore Mica 2.x: New Features and Enhancements for Spring Cloud Microservices

mica (Mica)

Mica, meaning “cloud mother”, symbolizes the core of cloud services, enhancing Spring Cloud functionality and making microservice development faster and easier.

Core dependencies of Mica 1.x

Mica is based on Java 8, has no legacy baggage, supports traditional Servlet and Reactive (WebFlux). It uses mica-auto to auto-generate spring.factories and spring-devtools.properties, depending only on Spring Boot and the Spring Cloud suite, with no third‑party dependencies, making it a rare core component for microservices.

Spring: 5.x

Spring Boot: 2.1.x

Spring Cloud: Greenwich version

About this version

This release mainly fixes bugs, thanks to contributions from GitHub users @fengyie007, @PlexPt and former colleagues.

Mica 2.x is built on Spring Boot 2.2.x with many optimizations and is no longer compatible with older Spring Boot versions. The internal VIP version has been incubated to 2.1.1; see the Mica 2.x changelog.

The open‑source version of Mica 2.x is expected to be released in April 2020.
