Java / Micronaut Interview questions
What is Micronaut?
Micronaut is a modern, JVM-based framework for building modular, testable microservice and serverless applications in Java, Kotlin, or Groovy. It was created by the team behind Grails and is now maintained by the Micronaut Foundation, with the current major line being Micronaut 5.
Unlike traditional frameworks that wire dependencies and scan annotations at runtime through reflection, Micronaut does most of that work at compile time using annotation processors. That single design decision is what gives it fast startup, low memory consumption, and minimal proxying overhead.
It ships with its own dependency injection container, an HTTP server and client, cloud-native integrations such as service discovery and distributed configuration, and first-class support for GraalVM native image compilation.
